I have tried everything I can think of and cannot get the 746 to
transmit. The audio from my speakers sounds perfect with no
distortion etc, but no transmitting. The card is the computer card
Realtek and I also tried with a USB external card, still no luck. Am
I missing something here ? If anyone has a solution I would
appreciate it. I might add the system was working perfect until about
a week ago...Thanks Mike K9HCK



 

RE: [digitalradio] Filter question

[David Little]

Paul,
 
It may help on PSK-31.
 
Olivia can use a bandwidth wider than the filter.  MT-63 and other modes
can also.
 
For this reason, I would look at how much I used the narrow bandwidth
modes and make your decision accordingly.  
 
To slow Olivia down to 250Hz BW needs to be considered in terms of duty
cycle and speed of delivery.
 
Just some thoughts to consider,

Re: [digitalradio] Mystery signal

[David]

Hi Jerryyou are seeing WSJT JT65A...a weak signal mode that was 
origionally made for EME work and has become a very widely used mode on 
HFthere are many stations worldwide using it as a DX mode.
in my mornings around 2030z to 2200z i often work stations in USA while 
in my evenings 0730z to 1000z i would be working into EU.sometimes 
with signal as low as -27 below the noise floor.
WSJT7 is available for Windows XP and may work on Vistait can also 
be compiled for LinuxJoe Taylor W1JT is the main author and the 
program can be found at his Princeton Uni site.there is a very good 
Bozo Guide written by Andy K3UK that will be a help to new users...its 
avaiable on the digitalradio site.

RE: [digitalradio] Re: How Can We Push HF Emcomm Messages to the Field?

[David Little]

We get quite good results in the 45 to 50 mile range using VHF SSB (2M)
and 5 watts with Olivia from fixed location to fixed location and low
gain omni vertical antennas.  From a mobile to a fixed location, 
 
I would estimate as good a signal on SSB as can be expected from the
same mobile to a repeater input on FM; unless there is a tremendous
height difference to offset the signal to noise gain of the SSB
transmission.

And further, this thought should be considered as VHF FM, or VHF SSB? In
a
base/mobile or mobile/mobile environment, SSB on VHF works over much
greater
distances. 

With voice communications, VHF SSB benefits from having flutter
resulting in
the desired signal amplitude going up and down, while the background
noise
level is held pretty constant, by the AGC in the receiver. FM is
opposite
in that regard - when the signal gets weak, the background noise level
comes
up, at least until the squelch closes. In my perception, I seem to be
better able to fill in the gaps in syllables when the signal drops out,
than
when it's filled with noise. 

VHF SSB also has the benefit of probably not requiring the mobile
station to
have to take time to set up an antenna. If the mobile station is parked
in
a null, chances are that moving the vehicle a few inches will change a
multipath situation enough to provide good copy. If there's benefit to
be
had by setting up a portable (v.s. mobile) antenna, putting a VHF
omnidirectional stick up 10-20' is a pretty trivial task. While there
can
be benefit to be had by using horizontal antennas, unless you're into
serious weak-signal work, it's not necessary to realize large gains in
coverage, even using omni antennas on both ends, using SSB.

Digital modes that are designed to work well in weak signal
circumstances on
HF SSB rigs will similarly work well on weal signal VHF SSB rigs,
because
the same "linear-mode" technology is involved. Probably the biggest
caveat
to that will be frequency accuracy and stability. Radios on a net will
need
to be well warmed up, or have high stability oscillators, if they are
operating unattended, and expected to be able to be received by the
sender.

I've encouraged those that are working on upgrading our regional
hospital
network to use the IC-706's that they already have set up for HF pactor,
to
try VHF pactor using the SSB mode, as a way to gain from the more
readily
available spectrum, so they don't have to compete for access to the very
few
frequencies available on HF for digital operations. It'll be interesting
to
see how they do.

If the base station has a 100 watt VHF radio like the 746pro - you might
be
able to still reach the volunteer, but he may not have enough power to
get
back to you.

Or he may be out of VHF range.

HF is the way to go - but both ends of the conversation need NVIS
antennas.
HF antennas tend to be large, and NVIS needs to be horizontal. I'm not
sure
there exists an NVIS antenna for a car or truck. Maybe something
horizontal
can be setup in the bed of a pick up truck? In general HF antennas for
vehicles do not perform very well - but they are better than nothing.

There are portable NVIS HF antennas available that can be setup rather
quickly. Perhaps this is something to be done when he arrives at his
destination, and then call the base on HF?

Also keep in mind that HF radios typically cost over a thousand dollars
compared to maybe two hundred for a VHF radio.

RE: [digitalradio] Re: How Can We Push HF Emcomm Messages to the Field?

[David Little]

FWIW, in the response to Gustav
 
It was known that Region 4 Resources would be deploying into the area in
support of the Southern Baptist Disaster Relief Organization.
 
Days ahead, info was exchanged on formal net operations in that area to
allow members from Region 4 to check propagation and effective
communications into what was projected to be the effective area; region
6, which is a fairly big target area.
 
Propagation, time of day and available frequencies were reviewed and a
net plan was decided on to allow the best chance for reliable
communications into the affected area for 24 hour operations to support
the deployed members from region 4 as they traveled into the affected
area, in-transit to their various support locations and to get them
safely back home to region 4.
 
NCS were lined up on 2 hour shifts, and a pool of 12 were scheduled to
make sure each day was covered in every 2 hour slot with a minimum of
operator fatigue.
 
One member was appointed to gather status reports on the deployed teams
and report up the chain of command
 
Weather conditions were constantly given directly to the teams via voice
to advise them what they were traveling into, as Gustav was leaving and
they were traveling into the edges of the affected area.
 
NVIS can be achieves with two 102" whips, one front and one back, joined
in the center over the vehicle, but it is better to have a support team,
trained and ready, to understand propagation, MUF, general band
conditions and be in emergency net operation with as many members as
possible making every attempt possible to shut and listen.  
 
The net can periodically be extended by NCS (Net Control Station)
calling for only stations with Good Readable to Loud and Clear copy on
NCS, and in turn having them make the same call to determine the relay
path.  An accurate region roster and some idea of geography helps NCS to
determine effectives of net and who to use for relay from deployed team
members, if NCS does not have directly copy.
 
NCS always chooses an alternate NCS, the furthest distance possible with
reliable copy.  This allows them to work together and achieve the
broadest working net, with just 2 members to start and direct the net.  
 
The net is closed at the end of the 2 hours, and a new net is
established with each oncoming NCS, which allows maintenance of the most
accurate net roster.
 
One member is appointed to track weather conditions in the path of the
deployed teams, as radio station coverage is minimal at best from local
broadcast stations,  Major media resources are monitored to keep abreast
of the fuel and power situation along the route.  Having plenty of fuel
in the ground is no good if the station has no electricity to pump it
out of the ground.
 
An open fuel station may clog one lane of a 4 lane divided highway as
vehicles line up for miles to exit and refuel.  The deployed members
need to be in the proper lane, before the traffic snarl happens.  They
also need to be in touch with federal resources in convoy to keep them
abreast, as the federal response may not be as well organized.
 
Cellular coverage is monitored.  MCS and ANCS use Skype to coordinate
the net via text chat.  Deployed members use Echolink where cellular
coverage allows use of their air card for wireless access to an ISP.
Winlink is used via aircard telnet/internet connectivity to direct
messages to a single or group address, giving a little privacy if they
are the first to arrive to a delicate situation and wish not to be in
the clear with their Sitrep..   
 
SHARES stations are active in the net, or on standby for direct access
to federal entities.  Phone Patch operators are on hand, ready to
provide first access into a developing situation that may involve
hazmat, mass casualty, etc.
 
While traveling, something like a TS-2000 in cross band mode could give
all members of a amateur caravan access to the HF net, if each member
had something useful to report; otherwise, VHF from car to car, and one
vehicle contained the team leader from each deployment group to relay
the Intel back into the net for distribution.  
 
OK, How am I doing so far?
 
Point to ponder: Anyone who deploys "without prior notice" has a highly
technical tactical designator assigned to them - "fool"

RE: [digitalradio] Global traffic and emergencies

[David Little]

Rick, Andy, All,
 
It is totally unreliable, undocumented and probably not reputable.  
 
I can't remember if it was during Huntsville or Dayton that the headshed
made these assertions and small publicity came out afterwards.
 
For the most part this discussion has always flown under the radar.
 
It never gets too much attention, and should probably be swept under the
rug as uncomfortable.
 
After all, All amateurs can directly interface with FEMA, GEMA, TSA,
EPA, and the other Agencies and Federal entities that make up the SHARES
network, so there is no need for any division between use of FCC (ARRL)
Spectrum and NTIA (MARS /  SHARES / Federal ) spectrum.
 
Someone has to provide "ground truth" reporting of the actual incident,
so I guess it should be an Amateur from a few hundred miles out, rather
than a local operator using last mile infrastructure.
 
I guess it is more comfortable thinking that the converse is the rule.
Think about it.  
 
If you were managing communications to save lives and property, would
you rely on relay, or direct contact?  
 
Would you expect remote reporting of local conditions from hundreds of
miles away, when last mile infrastructure was in place and able to do
so?
 
Would you use a group that maintained rigid net discipline and regular,
daily training, or someone who shows up to an Incident Command center
with a dead battery in his HT and hungry?
 
Would you expect your ARRL AREC diplomas to allow admittance to a
Incident Command site that is functioning under NIMS, or would you
travel with certificates of completion of IS100, IS200, IS700 and
IS800A?  (MARS is considering requiring both; at present, only ICS for
Billet Call holders are required.)
 
Do you know what NIMS is; what ESF#2 is, what the National Support
Framework is?.
 
Do you know what TWIC is?  (On December 2nd, you certainly will).
 
Emergency Communications is a subject that is undergoing great flux...
If wideband digital modes are what is required to send and receive an
IS213 form in proper formatting, it stands to reason that any Federal
response would require the medium that is capable of delivering.
Anything else is inviting failure.  If the mode is unwelcome on FCC
governed spectrum, and has an active and efficient network on NTIA
spectrum, which would you choose?
 
As for non ARQ modes, I have used MT-63, Olivia, and even played with
Contestia in 2000Hz bandwidths.  Each is somewhat useful for unformatted
text and forward error correction.  EasyPal looks very promising and the
programmers have been very responsive to tailoring it for the MARS
program; because someone thought enough to ask.  I hope that WinMor will
be in the competition with Pactor III and other Proprietary modes, but
it will all boil down to bandwidth necessary to carry compressed
information.  That is what the entire discussion is and has been about.
 
At present, the only way to get the job done to the requirements of the
served agencies, on a Federal Response is on NTIA spectrum, as they
allow wide-band digital formats.
 
Pay no attention to that man behind the curtain; I was only kidding.

David,

I have been a ham for many years and follow most all public 
service/emergency communications issues quite closely. I have never 
heard of your claims below from any reputable source. If you read QST 
and follow ARRL BOD decisions you would know that the ARRL has supported

any and all public service approaches. While it is true that there is 
the Winlink 2000 system that uses proprietary and non-proprietary modes,

there are also several non-proprietary systems to choose from with 
another on the way.

Some of these modes are wide bandwidth but kept within an MF/HF phone 
band width as required under Part 97 here in the U.S. Some of the 
digital modes which have been around for a long time can be near to, or 
even more than, 2000 kHz wide.

Even one of the The old MIL-STD-188-141A (often referred to as one of 
the ALE modes) goes back to development in the 1970's. And newer modes, 
e.g., MT-63, Olivia, etc. have been around for some years and are 
sometimes used in wide mode, depending upon conditions.

Point us to some of the actual source material you found that supports 
your belief about what the ARRL has done.

RE: [digitalradio] Global traffic and emergencies

[David Little]

We all have out opinions.
 
2.4 KHz is well within the 3.0 KHz bandwidth.  The desire of Hams to
operate on top of another station is another reason for serious
consideration of NTIA spectrum for reliable communications and the
discipline necessary to conduct them.
 
MARS still handles some MARSGRAMS also; mostly during holidays, so I see
no indication of competition with the license renewal notices and
birthday greetings relayed by the NTIS.
 
Unfortunately for those who want to send everything via 500 Hz in serial
format, all Federal agencies are looking for something to handle their
requests in formatted binary/compressed packages.  P1 and P2 can move
this along in an environment that is not time critical, but, in all
cases, if you want to get the info flowing in large quantity for timely
delivery, you have to dedicate the bandwidth to do so.  
 
That is why we aren't using 8 bit machines running at 4.77 MHz anymore.
 
Beginning to see a pattern here?
 
Cheers,

At this point in time most of the traffic is ham to ham. like welcome to ham 
radio, your license is about to expire, welcome to a new ham club (group of 
hams) etc..Some of these are also confirmation of messages received, birthday 
greetings and the like... This ia a free public service sponsored by NTS and 
the ARRL and if fact was one of the first ham related activities... The "relay" 
in American Radio RELAY League (ARRL) refers to this aspect of the hobby.
There still are the messages to the general public. In the times of 
communication emergencies (which is the prime reason for the existence of NTS) 
there are many health and welfare related messagesMany of these cannot be 
handled or delivered by any other means when the infrastructure supporting , 
the traditional phone system, cell phones and email disappears...The routine 
messages are a way of keeping the skills of trained operators honed or oiled if 
you will, to respond in a  structured fashion in an emergency or disaster 
without giving it a second thought... It becomes part of your operating skills.
"Amateur Radio -When all else fails."  Individual stations operating without 
any infrastructure but within a structured system, on emergency power, if 
necessary, have always been the hallmark of ham radio.

Note, that what I have been discussing is the digital aspect of NTS... Similar 
activites as well as traffic volume exists within the traditional NTS systems.  
NTS Digital is only a complementary system to traditional NTS and interfaces 
with it at all levels of NTS structure, from Transcontential Corps (TCC) to 
area, region, section and local..
Indeed the automated portion of NTS Digital would not be successfull without 
these links to the traditional NTS operator structure

  I was surprised because so many people use email and cell phones.  Where does 
this volume come from?

RE: [digitalradio] Global traffic and emergencies

[David Little]

Another example of why ARRL turned over all long distance (HF) emergency
communications to the MARS organizations and agreed that Hams were to
provide only  last mile (VHF/UHF) emergency communications.
 
The Ham community showed their distaste for P3, so it has been largely
moved to NTIA frequencies.  
 
Unfortunately, it set the stage for loss of confidence in the Amateur
Community for Emergency Communications over a long range, unless they
are self-funding the entire response..
 
There still are some RMS Pactor stations on the Ham spectrum, and some
using P3 for Keyboard to Keyboard use.  
 
Most of them are candidates for MARS service as they continue to get the
flack from the contesters.
 
Everyone eventually gets whet they want.  Some are late to realize that
what they got in return wasn't actually what they wanted...
 
Enjoy,

While we in this area was up to our back side with water
early this year Pactor and WinLink work just fine for us.

FEMA as well as SEMA Just loved that they could get updates via 
their blackberry. You must first understand that in the rural areas 
such as this there is very little cell coverage if any.

If it was not for HF and WinLink a lot of info would have not gotten
from point "A" to point "B".

I know that just made a lot of the anti pactor - anti wide shack in
their shoes. Deal with it, once again it worked.

Maybe soon something new and better will come down the line.

Re: [digitalradio] Does an NTS Digital Net Station run 24/7 allband HF?

[David Struebel]

Bonnie,
NTSD is complementary to the traditional NTS structure and interfaces with it 
on all the NTS structure levels.  It is administered through the NTS structure 
at area level by Area Digital Coordinators each reporting to the NTS Area 
Chairperson.
NTSD automated stations are one transmitter scanning the indicated HF bands.  
Usually some soft of all band antenna is used with automatic antenna tuners.
My station is a Kenwood TS-450S, a 135 foot doublet, with a MFJ 993 
autotuner Modem is a SCS PTC-IIex.  My VHF  packet link is a Kantronics 
KPC-3+ which feeds into my NTS PBBS and the Eastern Flexnet system
The majority are using Winlink classic with Winlink classic scanner software. 
This is an older piece of software originally developed as APLINK (AMTOR and 
packet) by many of the same authors who later developed  Winlink 2000 and can 
be run on a very modest computer. For instance I am using a Pentium 166 MHz 
computer and Windows 98SE.   Some stations are running Winlink 2000 and some 
are using Airmail.
Again the majority have multiple Pactor mode capability using the SCS modems. A 
couple of the automated stations are Pactor 1 only typically using a PK-232MBX,
not everyone can afford a SCS modem... We do have an equipment bank with Pactor 
1 capable Pk-232MBXs to bring a new station on the line, as other stations 
leave or lose interest... Most who come into our ranks eventually upgrade to a 
SCS modem, at least two operators in the past two years You may get a 
fuller look at NTSD operation from this web page

http://home.earthlink.net/~bscottmd/n_t_s_d.htmthe stations and frequencies 
may not be exacly up to date but it wil give you an idea Most of the 
participants in NTSD are Digital Relay Stations manually connecting into the 
various automated systems.

Copied into this message are the operators of the Eastern area MBO stations, 
our ARRL contact, Steve Ewald WV1X, and Dave Knight W4ZJY, and George Thomas 
K7BDU, the Digital Area Coordinators for Central and Pacific area NTSD, 
respectively Marcia, KW1U in addition to being a MBO is also the Chair of 
Eastern Area NTS staff.

Hope that answers your questions... As I noted before, my original comment was 
not to be little HFLink ALE operations, just trying to let you know we are 
still out there after all this time.

  Hi Dave WB2FTX,

  Does a station in the NTS Digital net
  operate 24/7 on all HF bands simultaneously?

  Does a typical station in the NTS Digital net use 
  8 transceivers to achieve simultaneous operation 
  on the 8 HF bands 
  80m/40m/30m/20m/17m/15m/12m/10m?

  Or, does each NTS Digital station scan every HF band? 

  What type of software/hardware does a typical 
  NTS Digital station use to achieve allband 24/7 HF operation?

  I'm very curious about it, because none of the 
  publicly available information by NTS indicates 
  that any station in the net is running 24/7 allband HF.

Global Emergency Network Marks Record (Nov 19, 2008) -- The Global ALE High 
Frequency Network (HFN) -- an international Amateur Radio Service organization 
of ham operators dedicated to emergency/relief radio communications -- has 
become the first network to operate continuously for more than 500 days on all 
international Amateur Radio shortwave bands simultaneously. According to HFN 
International ALE Coordinator Bonnie Crystal, KQ6XA, the main purpose of the 
Network is to provide efficient emergency and disaster relief communications to 
remote areas of the world. "Beginning with a core group of six North American 
radio operators in June 2007, HFN rapidly expanded to cover large areas of the 
planet with 24/7 digital communications," she said."HFN was designed to be an 
open framework for global Amateur Radio emergency services to interoperate on 
HF using the Automatic Link Establishment (ALE) system." Relying on ionospheric 
radio communications,
interconnected HFN base stations scan the radio bands every 10 seconds, 
from 3.5 MHz-28.0 MHz. Through this Net, Crystal said, ham operators stay 
connected with each other at all hours of the day or night in any mode of 
operation, and can send Internet e-mail or cell phone mobile text messages from 
the field."

RE: [digitalradio] Black Friday deals of interest to hams

[David Little]

On the Dell, better be sure to buy a powered USB hub for Ham use.
 
I spent a few hours getting the sound and printer going on a new one for
a relative last week.  
 
The Dell USB powered speakers, keyboard and mouse consumed 3 of the rear
USB ports.  A Brother color laser printer took up the fourth one.
 
Until I was able to balance the load among the 4 USB ports in the back,
there wasn't enough current available for stable voltage to get a
recognition signal on the bus for Vista to identify the USB items and
activate them for use.
 
With most ham software written for Serial ports (which haven't been
standard on computers for nearly a decade), the need for high enough
current reserve on the USB bus is a must.
 
Dell managed to fall below the minimal acceptance on this model, but a
properly powered external USB Hub will probably solve the problem.
 
Otherwise, it looked to be an OK computer for beginner or dedicated
purpose.  
 
I don't know how the sound card would do on digital modes, but it did
have front-mounted line in and headphone out jacks, and the sound applet
lets you disable rear channels and special effects for straight stereo
and 2 speaker operation.

[digitalradio] Re: Sound card question

[David Freese]

The following is an excerpt from the web page "Sights and Sounds of
Digital Signals", http://www.w1hkj.com/FldigiHelp/Modes/index.htm.

THOR Modes

General Description

THOR is a family of offset incremental multi-frequency shift keyed
modes with low symbol rate, closely related to DominoEX. A single
carrier of constant amplitude is stepped between 18 tone frequencies
in a constant phase manner. As a result, no unwanted sidebands are
generated, and no special amplifier linearity requirements are
necessary. The tones change according to an offset algorithm which
ensures that no sequential tones are the same or adjacent in
frequency, considerably enhancing the inter-symbol interference
resistance to multi-path and Doppler effects.

The mode has full-time Forward Error Correction, so is extremely
robust. The default speed (11 baud) was designed for NVIS conditions
(80m at night), and other speeds suit weak signal LF, and high speed
HF use. The use of incremental keying gives the mode complete immunity
to transmitter-receiver frequency offset, drift and excellent
rejection of propagation induced Doppler.
Protocol

These are unconnected, manually controlled message asynchronous
simplex chat modes, using binary convolutional Forward Error
Correction. The default calling mode is THOR11.
Coding and Character Set

A binary varicode with ASCII-256 user interface (same as MFSK16) is
used. Lower case characters are sent faster. An ASCII-128 secondary
character set extension allows a fixed (typically ID) message to be
sent whenever the transmitter is idle. Modulation uses two dibit
pairs, symbol synchronous, differential.

The FEC system uses binary convolution to generate two dibits per
varicode bit, and halves the corrected data rate compared to the
equivalent DominoEX mode. Rate R=1/2, Constraint length K=7,
Interleaver L=10 (40 bits).
Operating Parameters Mode   Symbol Rate Typing Speed1   Duty Cycle2 
Bandwidth3  ITU Designation4
THOR45  3.90625 baud14 wpm  100%173 Hz  173HF1B
THOR55  5.3833 baud 22 wpm  100%244 Hz  244HF1B
THOR85  7.8125 baud 28 wpm  100%346 Hz  346HF1B
THOR116 10.766 baud 40 wpm  100%262 Hz  262HF1B

THOR22  21.533 baud 78 wpm  100%524 Hz  524HF1B

Notes:

1. WPM is based on an average 5 characters per word, plus word space.
Values based on sending 100 "paris " words.
2. Transmitter average power output relative to a constant carrier of
the same PEP value.
3. This is the "Necessary Bandwidth" as defined by the ITU.
4. A summary of the ITU Designation system can be found at
http://en.wikipedia.org/wiki/Types_of_radio_emissions

5. Double spaced mode.
6. Default and normal calling mode.


Implementation details are contained in the GPL software source code
for fldigi which can be downloaded from the following site:

http://www.w1hkj.com/fldigi-distro/fldigi-3.03.tar.gz

This is a tar zipped format that will be familiar to all Unix, Linux,
Free BSD and OS X developers.  Windows developers can unzip this type
of archive using one of several archive managers including PKZIP.

Fldigi is open source source software that is licensed under the

incorporate into a commercial product.  You must however abide by the
the license under which it has been developed and published.  To date
one other amateur product has used fldigi source with great success,
DM-780, by Simon Brown.

DominoEX-FEC and THOR differ in two ways:

The FEC table structures in DominoEX-FEC have been manipulated in a
way that prevents the transmission of control codes.  THOR uses the
same FEC table as MFSK and can transmit the full ASCII character set.
 The interleave used in THOR is longer than used in DominoEX-FEC, and
it will have a slower throughput but greater immunity againts multi-path.

Fldigi can encode and decode both DominoEX-FEC and THOR.

  Let's practice for 30 minutes on Thursday night to check out our stations
  for CQWW RTTY this weekend. Actually, let's do 30-minute practices to
  accommodate Europe better. The first one is more convenient for Europe and
  the NA East coast should be able to work them on the low bands. (20 will be
  fading on the P4-EU path while 80 will be starting up . 40 should be solid.)
  The later practice will accommodate NA coast to coast, primarily on 40 and
  80 except for local ground wave on the higher bands.

  2300-2330 UTC, Thursday 25 September

  0200-0230 UTC, Friday 26 September

  Hope to work everyone everywhere on the weekend. Just need to get some more
  things fixed at the station here between now and then!

Sorry,
Can't do anything with a KAM or PK-232 (any version).  Pactor II and III are 
proprietary modes.
Pactor II and Pactor III are only available on the SCS line of  modems 
Cheapest one is the PTC-IIex about $900... Check this web site for their
US distributor

http://www.farallon.us/webstore/

The PTC-IIex with only Pactor II is $859, with the Pactor III license it's 
$998.

Do you need need all that speed?  All Pactor connects start out in Pactor I, 
and only shift if the higher configuration is available at both ends.
What are you going to use it for?   Winlink 2000?

Hello all,

Just to say that aside to Olivia, you have a mode which name is 
Contestia,
which is twice quicker than Olivia and almost as sensitive. It is 
built on
the same principle as Olivia but with different parameters and a 
reduced set

of characters.

It is present at least on Mixw and Multipsk

RE: [digitalradio] CW - last resort?

[David Little]

Isn't this just precious.  .  
 
The move is divisive, and obviously geared toward attrition.  Navy seems to
be leading the charge
 
Chief NAVMARMARS managed to honor tradition, and managed to make policy move
back toward the stone age.
 
Nice tantrum.
 
What a comfort.
 
I will sleep better at night.
 
For those that haven't followed the media campaign, MARS is moving toward a
Customer-Based Emergency Communications organization.  
 
Since they are now involved directly with TSA and other Gov't ESFs, it seems
only logical that they should try to pass their customer's traffic in CW.  
 
After all, it is more common than Latin, and all of their customers will
certainly be able to copy.  
 
Further note,  I don't think he really views CW as a last resort.

RE: [digitalradio] ARRL Introduces "Fifth Pillar" at Dayton HamventionR

[David Little]

Too bad all the potential hams that wanted to hear this 20 years ago are now
top Cell Phone engineers, WiFi Gurus, running Satellite Radio stations,
etc.  

Paragraph 4 is the affirmation of this and the effect from the cause.  It
could have read that professional technical minds have always gravitated
toward Amateur Radio as a means of expanding their understanding.  But,
thanks to the league, they chose to take their talent elsewhere. The league
spoklesperson forgot to include the identifier "senior" hams attribute their
affininty to Amateur Radio as launching their professional careers.
Somehow, the league's steerage has driven the wheels of the concept of
keeping up with technology; until now (Wink, Wink - Nudge, Nudge).

I sure hope they didn't miss the chance to break this earth shattering
decision to the world on a CW broadcast.  Oh. Wait a minute; I have erred.
That should have read a RTTY broadcast - After all, this is the 21st
century.


The league of exceptional shortcomings in foresight has spoken again.  Don't
tell these guys about USB or Firewire interfaces - it might confuse them...

ARRL Introduces "Fifth Pillar" at Dayton HamventionR
On Saturday, May 17 at the Dayton Hamvention, ARRL President Joel Harrison,
W5ZN, plans to announce that the League will expand its identity program to
include greater emphasis on technology. Harrison explained that "Ham radio
operators, and particularly ARRL members, closely identify with current and
emerging radio technology. Today, we are naming 'technology' as ARRL's new
fifth pillar." ARRL's other four pillars, the underpinnings of the
organization, are Public Service, Advocacy, Education and Membership. "For
hams, expanding the four pillars to include technology will reinforce one of
the organization's guiding principles -- that ham radio is state-of-the-art,
innovative and relevant," he said.

"Radio amateurs have entered a new era. More than a dozen Amateur Radio
satellites are presently in orbit with more to come. Software is expanding
the capabilities of their radio hardware and communication by digital voice
and data is expanding rapidly among hams," Harrison said.

In addition to the new fifth pillar, the ARRL has launched a year-long ham
radio recruitment campaign emphasizing the Amateur Radio Service as a
scientific national resource. The campaign invites newcomers to discover ham
radio in the 21st Century -- where hams are using science, technology and
experimentation to explore the radio spectrum. "For more than 90 years, the
ARRL has been at the forefront of technology, encouraging experimentation
and education through its license training resources, publications and
periodicals. ARRL provides its members with top-notch technical information
services, trusted product reviews and radio spectrum advocacy," Harrison
said. "The ARRL Laboratory is a centerpiece of ham radio technology,
contributing to radio electronics experimentation, spectrum development and
advocacy, and radio frequency engineering."

Harrison also noted that many hams attribute their affinity to "Amateur"
Radio as launching their professional careers in radio engineering,
satellite communications, computer science and wireless communications.

"This is less about defining a new course for Amateur Radio, but simply
recognizing a course that has always been a precept of radio amateurs and
the ARRL," he said. Referring to the federal rules and regulations for
Amateur Radio, Harrison explained that one of the defining principles of the
Service's very creation by the government is the amateur's proven ability to
contribute to the advancement of the radio art. Harrison remarked, "Today's
technology is nothing new to ham radio!"

[digitalradio] how ?

[David Michael Gaytko // WD4KPD]

yesterday looking around 30m with psk(not sure if 31 or 63), i saw, but 
did not catch the tail end of a signal in the waterfall with a "73" 
printed after it.

this did not look like an video id as used by multipsk.  this signal was 
simply formed by the psk signal itself.

anyone got an idea ?

RE: [digitalradio] Best line of the day

[David Little]

Olivia would be a much better choice for critical information.
 
Next would be Contestia, then MT-63.
 
MFSK-16 should also be a consideration
 
Within all 3 of these are variations in number of tones and bandwidth that
will give you choices based on propagation.
 
PSK-31 is a narrowband "one-shot" digital mode.  It is the "least common
denominator" as it requires zero learning curve.
 
FEC, and finally ARQ will both yield more accurate results.
 
I don't waste my time on the amateur bands with Pactor III due to the
bandwidth arguments, but use it on NTIA freqqencies and it would be my first
choice to save life and property.  PSK would fall somewhere around the
Campbell Soup can and twine category...
 
Just tools in the toolbox.

I agree. Static crashes are a powerful QRN source here too.

Guess Olivia would be better, even 8/250 would stand a better chance of 
good copy.

In spite of strong signals, if there is no "second chance", it does not 
matter much how clever Varicode is. It is certainly a big step ahead on 
quiet bands, but when QRM dominates, it is simply not enough.

That's what happens when there are static crashes, like those from the
string of cells (or super-cells) moving  across the Eastern US.  
 
Got FEC??
 
The station could improve the odds against him by using faster (or no AGC)
for quicker recovery time to lessen the lost data (again, no FEC - no
redundancy- no second chances)...
 
Of course, the ease of using PSK as opposed to a mode with error correction
attracts the masses, and is is narrow bandwidth...
 
The station probably was actually decoding everything, including the static
crashes and resulting lost data....

I saw this today...

 Yes I copied you fine. Can't seem to transmit back though. No tones
out

 Well Andy has the same trouble, I'm on VOX on the Kenwood TS450s

Anyone have any idea why JASON generates no audio at all for some people?

Re: [digitalradio] Re: another non- contest on a no contest band

[David]

Hi AllSSB is allowed by all countries on 30m..

SSB stands for Single Side Band and is a form of modulation and not a 
Mode as suggested by some.many people use SSB to mean Speech or 
Voice which is a Mode and a misuse of the term SSB.

RTTY is sent in LSB or Lower Side Band form of SSBmost digital modes 
are USB another form of SSB.all allowed on 30m.

i think you will find in most Amateur Radio Regulations of all countries 
that Voice or Speech is donated as such and not SSB

Yes i know this is a usage hangover from the 'wars' between ops of AM 
and SSB but by now should be buried and the terms used correctly.AM 
Voice or SSB Voicejust as the new technology is being called Digital 
Voice

The misuse of terms is also confusing to new hams who in classes are 
taught correctly..

I know im going to get some flames for this but who cares...i dont as it 
is correct

[digitalradio] another non- contest on a no contest band

[David Michael Gaytko // WD4KPD]

30 Meter QRP Weekend April 19th & 20th

10.140  +/- 1000 PSK
(10.135 – 10.145 – HELL,OLIVIA,RTTY,Etc)


for all intents and purposes, this non-contest is still a contest.
there is a sponsor, and bragging rights are earned by the contesters
in the organization.

it may be legal, but still in poor taste.

They Criticized Vista. And They Should Know. 

By RANDALL STROSS

ONE year after the birth of Windows Vista, why do so many Windows XP users
still decline to “upgrade”? 

 
<http://topics.nytimes.com/top/news/business/companies/microsoft_corporation
/index.html?inline=nyt-org> Microsoft says high prices have been the
deterrent. Last month, the company trimmed prices on retail packages of
Vista, trying to entice consumers to overcome their reluctance. In the
United States, an XP user can now buy Vista Home Premium for $129.95,
instead of $159.95.

An alternative theory, however, is that Vista’s reputation precedes it. XP
users have heard too many chilling stories from relatives and friends about
Vista upgrades that have gone badly. The graphics chip that couldn’t handle
Vista’s whizzy special effects. The long delays as it loaded. The
applications that ran at slower speeds. The printers, scanners and other
hardware peripherals, which work dandily with XP, that lacked the necessary
software, the drivers, to work well with Vista.

Can someone tell me again, why is switching XP for Vista an “upgrade”?

Here’s one story of a Vista upgrade early last year that did not go well.
Jon, let’s call him, (bear with me — I’ll reveal his full identity later)
upgrades two XP machines to Vista. Then he discovers that his printer,
regular scanner and film scanner lack Vista drivers. He has to stick with XP
on one machine just so he can continue to use the peripherals.

Did Jon simply have bad luck? Apparently not. When another person, Steven,
hears about Jon’s woes, he says drivers are missing in every category —
“this is the same across the whole ecosystem.”

Then there’s Mike, who buys a laptop that has a reassuring “Windows Vista
Capable” logo affixed. He thinks that he will be able to run Vista in all of
its glory, as well as favorite Microsoft programs like Movie Maker. His
report: “I personally got burned.” His new laptop — logo or no logo — lacks
the necessary graphics chip and can run neither his favorite video-editing
software nor anything but a hobbled version of Vista. “I now have a $2,100
e-mail machine,” he says.

It turns out that Mike is clearly not a naïf. He’s Mike Nash, a Microsoft
vice president who oversees Windows product management. And Jon, who is
dismayed to learn that the drivers he needs don’t exist? That’s Jon A.
Shirley, a Microsoft board member and former president and chief operating
officer. And Steven, who reports that missing drivers are anything but
exceptional, is in a good position to know: he’s Steven Sinofsky, the
company’s senior vice president responsible for Windows.

Their remarks come from a stream of internal communications at Microsoft in
February 2007, after Vista had been released as a supposedly finished
product and customers were paying full retail price. Between the nonexistent
drivers and PCs mislabeled as being ready for Vista when they really were
not, Vista instantly acquired a reputation at birth: Does Not Play Well With
Others.

We usually do not have the opportunity to overhear Microsoft’s most senior
executives vent their personal frustrations with Windows. But a lawsuit
filed against Microsoft in March 2007 in United States District Court in
Seattle has pried loose a packet of internal company documents. The
plaintiffs, Dianne Kelley and Kenneth Hansen, bought PCs in late 2006,
before Vista’s release, and contend that Microsoft’s “Windows Vista Capable”
stickers were misleading when affixed to machines that turned out to be
incapable of running the versions of Vista that offered the features
Microsoft was marketing as distinctive Vista benefits.

Last month, Judge Marsha A. Pechman granted class-action status to the suit,
which is scheduled to go to trial in October. (Microsoft last week appealed
the certification decision.)

Anyone who bought a PC that Microsoft labeled “Windows Vista Capable”
without also declaring “Premium Capable” is now a party in the suit. The
judge also unsealed a cache of 200 e-mail messages and internal reports,
covering Microsoft’s discussions of how best to market Vista, beginning in
2005 and extending beyond its introduction in January 2007. The documents
incidentally include those accounts of frustrated Vista users in Microsoft’s
executive suites.

Today, Microsoft boasts that there are twice as many drivers available for
Vista as there were at its introduction, but performance and graphics
problems remain. (When I tried last week to contact Mr. Shirley and the
others about their most recent experiences with Vista, David Bowermaster, a
Microsoft spokesman, said that no o

Hi Eric...we have the same problem here in VKwhen you buy a computer 
you have to take the o/s that they want to load..if you try and buy 
one without an o/s you get told in no uncertian terms you cant.i 
have looked into the consumer protection regulations and found that it 
may be illegal to force you to buy what you dont wantapparently 
there must be choice.try telling that to a salesman or a store 
manageryou get pointed to the door..if i bought a new PC or 
Laptop i want it with out an o/s as i would want to load Linux and if 
you tell the salesperson that you get a lot of sales tripe that is 
usually not true but is fed to them via the Gates  propaganda 
machine...you may find a store where a salesperson has tried or uses 
Linux and you then get a better hearing but you still may not able to 
buy what you want.
check the consumer regs in your State or Country before you go and buy

RE: [digitalradio] Re: 10 Tips for the PSK31 Digital Mode

[David Little]

One more consideration is AGC recovery time.
 
Slow AGC and static crashes are not a good combo in many of the digital
modes.  
 
No AGC or Fast AGC will make a difference in that situation.
 
This may not apply to PSK-31 as much as more complex digital modes, but a
point worth considering.
 
DSP filtering of signals above and below the signal you are trying to copy
are also a great help; if your rig will allow that narrow of a passband.

Subject: Re: [digitalradio] Re: 10 Tips for the PSK31 Digital Mode



There is no difference between an RF gain control and AGC. AGC is just 
Auotmatic Gain control instead of manual gain control.

The only way to copy a weak signal adjacent to a strong one is to prevent 
the strong signal from affecting the AGC, and the only way to do that is by 
using a narrrow filter or notch filter (at IF, not audio) to attenuate the 
strong signal.

You can use a wide (SSB) filter to see all the stations in the passband, and

then use Passband Tuning or IF Shift, or a narrow filter (at IF, not audio!)

to narrow in on the station you want to work if it is one of the weaker 
ones. You do not need to do anything for the strong signal unless it is 
overloading your front end and then you can switch in attenuation and switch

it out again when you are finished.

Many people have experienced a weak PSK31 signal disappearing or waterfall 
darkening when a strong signal comes on. This is because the strong signal 
is reducing the gain (and therefore the noise background), just the same as 
if you manually reduced the gain, and generally the only cure for this is 
using narrow filtering. Some receivers, designed specifically for PSK31, 
such as our latest PSK-20, do not use AGC, but distribute gain in such as 
way that it can copy weak signals adjacent to strong ones, without 
distorting the last IF stage or detector, but few transceivers can do this.

RE: [digitalradio] MARS WinLink in Tennessee Storms

[David Little]

Ken,
 
The Katrina After Action  Report (AAR) brought Amateur Radio back into play,
based on it's effectiveness in the pandemonium following the hurricane.
 
By the end of 2006, MARS was facing de-funding and cessation of existence.
 
The dynamic was the need for Emergency Communications as demonstrated as
recently as the past year, and the number of MARS members who were all
dressed up with no place to go.
 
Put in this perspective, the happenings of the past year seem to make more
sense.
 
The Huntsville Hamfest in 2007 is where the MARS Chiefs decided to interact
as a Tri-Service MARS organization (while retaining their own identity to
the branch of service they represent), and the ARRL decided to enter into a
MOU with MARS in which the division of responsibilities was defined.  
 
The outcome of that was the division between long-range (HF) and last mile
(VHF) communications during disaster support emerged.  
 
For years, in the background,the SHARES (SHAred RESources) HF folks have
been operating as the nucleus for communications infrastructure continuity
between the various Federal entities, as well as Infrastructure providers.
This group allows interaction between all Federal entities as well as the
ones in the volunteer support field(s) who have been licensed into the
system.  In SHARES operations, a MARS Volunteer who is licensed into the
system may directly contact any Federal Agency or Infrastructure  Provider
in net operation or disaster support.  
 
The same thing (on a smaller scale) has been implemented in the concept of
Local Emergency Planning Committee (LEPC) groups on a county to county
basis, where all players interact to provide the most up-to-date plan for
emergency operations.  This allows for Fire, Law Enforcement, Major
Business, Education, Manufacturing, Utility; any entity large enough to need
an emergency plan to meet and keep up to date with each-others needs and
capabilities.  
 
Amateur Radio is well represented in out county.  We will have up to 8
redundant stations by the end of this summer, each paid for by the
organization needing the support.
 
It is blending toward a generic team of communications providers, in which
(currently) an Amateur Radio Service license is the common bond.

Dave,

First of all, I will be the first to admit that I'm not up on all the 
latest technology.

BUT, I have felt for a long time (34 years to be exact), that the heyday 
of amateur radio emergency communications is long past. 

If we look back to the 1930's and so, radio communications was rare and 
hams could provide extraordinary communications during an emergency 
compared to anything else available. Even in the 1950's and 60's, local 
governments could be easily isolated and would have to depend upon ham 
radio in an emergency.

But during the 1970's and later, police, fire and other government 
agencies greatly expanded their ability to communicate even during 
emergencies. Individuals hams with a portable station were able to 
contribute less and less. A modern fire chief at a disaster isn't going 
to accept a ham with a hand held trying to get communications through to 
a certain heavy rescue truck or mutual aid unit. By the time Katrina 
came along, government agencies were expecting internet bandwidth and 
cell phone capabilities and that is certainly far beyond the realm of 
individual hams or even local ham organizations. 

Modern communications and the government's need for same has gone far 
beyond the scope and abilities of ham radio. 

I was very active with AREC and RACES during the late 60's and early 
70's, (county EC and RACES Radio Officer) but I realized then that if I 
wanted to contribute to the community, I could do a million times more 
as a volunteer firefighter. Ham radio could only make minor 
contributions while trying to relive the glory days of earlier decades. 
Those days are long gone, I'm afraid.

OTOH, perhaps it's good to see MARS actually doing something productive 
in this area. I was very active MARS in the 60's but was dismayed that 
it did nothing to follow fulfill it's charter of providing emergency 
communications.

RE: [digitalradio] MARS WinLink in Tennessee Storms

[David Little]

It is interesting , isn't it?

MARS doesn't hold contests.

MARS doesn't allow stations to intentionally interfere with other stations.

MARS doesn't promote awards for the number of contacts you can make in a
minute and not say anything.

MARS doesn't get their panties wadded up when information is exchanged
without being interfered by contesters, QRN or jammers.

Army MARS offers training  during 90% of it's net operations.

MARS has requirements for membership.

MARS promotes discipline and efficient operation.

MARS gets to play on NTIA spectrum and doesn't have to subject itself to the
bonfire of vanities experienced on ham frequencies.  

Kid of sets a precedent, doesn't it.

This probably goes as far as any other single example to explain why the
ARRL relegated the Amateur Radio community to the realm of last mile (VHF)
communications in support of emergency communications and abdicated the HF
realm to the Tri Service MARS organizations.  Bread and Circuses has worked
since Roman times; why should this be any different.  

The ARRL knew when to throw in the towel, and had a pretty good idea about
the quality of their members; as well as their devotion level to do the
tasks traditionally required of the Amateur Radio Service in exchange for
the spectrum they enjoy.  The operation has been a success; the patient is
definitely dying

Pactor III is probably more effective than CW ever was as a 'filter" to
determine the dedication level of emergency communicators.  

But, you have to consider that there is not a HF rig less than $500.00 new,
and entry level for a HF rig that utilizes the best of 20th century
technology starts around $1200.00 

With that said, you can begin to appreciate that the $900.00 cost of a
Pactor III controller (taking advantage of the 10% discount for Emergency
Communicators) will deliver the mail, with the cheapest HF rig.  A PTC-IIex
controller connected to an Icom IC-718 cost about what an IC-7000 or a
little less than a TS-2000 costs; in a field of choices that can cost up to
$15,000.00 for a HF rig alone.  

The "Contest Grade" of transceivers that go north of ten grand will clog up
the airwaves and render them unusable by others far more often than Pactor
III and WL2K.  

Anyone saying that frequency usage during a contest is less adversely
affected than by WL2K transmissions using Pactor III is sadly being less
than truthful with their self and others, and there is simply no room for
discussion to the contrary.  A little intellectual honesty will trump knee
jerk reaction every time

Emergency Preparedness in our county in Glynn County, GA currently includes
8 SCS Pactor III controllers.  At least 4 more are scheduled for purchase
prior to Hurricane season.  

The reason for this is that nothing else will come close to the throughput
and devotion of the WL2K system when other infrastructure is down.  

The county services have now learned the importance of owning their own
amateur radio equipment and promoting operators from within their ranks to
be able to have the additional layer of communications infrastructure
available and in play during time of emergency.

I would say this is a wake-up call, but, sadly, wake-up calls concerning the
Amateur Radio Service are a small spot in the rear-view mirror.  

So, it is entirely predictable that the Amateur community would resist WL2k
and Pactor III.  It does what they no longer have the devotion to do.  I
continue to refine my ear, and ability to work voice under less than optimal
conditions.  I continue to refine my station(s);  fixed, mobile and portable
in an attempt to be prepared to do the job required to retain the Amateur
Radio Spectrum.  Pactor III is a tool that I use very sparingly.  I am very
fortunate to be able to use it freely on the NTIA spectrum, and, given a
choice, it is a no-brainer which service will handle the most traffic during
an emergency situation.

To a "T", the amateur radio community will continue to resist, until they
have no ground under their feet.  Spectrum refarming is very lucrative for
funding .  The FCC may seem slow, but they do have a little more will to
survive than others under their blanket seem to...

All in all, it is progress.  The direction it is taking isn't pretty, but
the outcome will include Pactor III, I am not too sure it will include
Amateur Radio...  Laughing last will be a hollow victory in this case

I have used the serial cable from my rig to my tnc with no problems. 
The person who has monitored my signal can't hear me with my dummy
load.  The PSK-31 cable that I got from Associated Radio is sealed and
 I can't tell how the interface box or DB9 looks like.  Unhooking the
microphone does no good.  When I unhook the interface cable while
talking thru the microphone the interference goes away immediately and
vice verse.  It doesn't matter which end I disconnect.  I have no
problems with the microphone and speaker lines from the interface.  I
have tried wrapping the cable in aluminum foil.  I am using 450 ohm
ladder line to my mfj deluxe tuner which probably doesn't help it
much.  I pulled my ground from my ground rod and if there is a ground
now it would be thru my house service.  My tuner, rig and computer are
within 3 ft of each other. I have not heard my signal but have been
told by more than one person that is has rf on it.  I could get a
recording of it if needed. I don't feel that this problem just
started, I just haven't used the cable to transmit.  I have a picture
frame shaped ferrite of about 1 in square that I tried but it didn't
help.  I have a cube shaped screwdriver magnetizer that I just thought
of trying with the other ferrite.  I have not yet tried the beer can
that KC7CJO suggested.  Thanks to both of you for responding.

Hi Jack.you will note that the digitalradio group is populated by

merits of various digital modes.and the regulations controlling them
they forget that they are only a percentage of the Amateur Radio 
Operators from around the world and we who are the "others" are having 
to put up with there arguing
on two occasions i have withdrawn from this group due to the fact that 
two thirds of the e-mails coming into my mailbox i dont want to read as 
they are nothing but rubbish that doesnt interest this ham who lives in 
another part of the world
i have suggested that maybe another group be started  so that those who 
want to argue there points of view do so away from the rest of the world 
who are interested in DIGITAL MODES and DIGITALRADIO without all the 
arguments.This idea has not been taken up...

I bet that guy did not have a clue, he has a hardware box that can
only use Amtor/Pactor. probably PSK31 and a couple of other
modes.most of which he can't, or has never used. He has probably
never been on any Internet forums or newsgroups, so he has not a clue
what is going on in the digital world of Ham Radio, nor does he 
probably care.

I would cite a lack of knowledge of modes and bandwidths etc on his
part, maybe he thinks the various digital modes all have retrys and
error correction..so it will just sort itself out and all modes
will simply "share" frequencies!
Yesterday, I was on 20m and I heard a stack of signals which were not
Pactor (I had a Pactor sked setup) I switched to PSK31 on my hardware
boxno go. I fired up HRD on my SLUSB, still no go :-( I was not
sure what signals they were, to be able to try and resolve them,
being just interested in what they were. Being a little tone deaf and
not having an intimate knowledge of all the modes and what they sound
like, did not help me.
Were they MT63? PSK250? I don't know If you run Digipan,
you have no hope!
With the increasing number of new modes being developed, the problem
will get worse :-( Add the coming of improved propagation and this
will become a spectrum quagmire in which no one will be able to
operate easily.
We have all helped create the mess we have. A gazillion software
programs, all doing their "own thing" some with many modes and
expanding more modes, nearly daily, others that don't have so many modes.
No software that I know of has a decoder function, with an "identify
signal" menu. Unless the software guys can come up with something
like that as an integrated or standalone solution, the schemozzle
will get worse.
IF people can identify a signal, with callsigns, they will be less
inclined to interfere with it, if a operator can't resolve a
signal.they probably care a lot less about any interference to it.
Sadly, only soundcard software solutions can be given this signal
decoder ability, hardware boxes are a different deal. You need
operator digital modes knowledge too, many people do not know what
all the modes sound like, I know I don't, even though I have a

Hi Jack.you didnt mention the 20m frequency that you were on and

have been a digital op since 2000 and even i get problems with some 
digital modes..im usually on 14076 most evenings using 
JT65A..this looks like a carrier on the left side and tone dotes out 
to the right.it is part of the WSJT suite of modes.every night i 
get what are obviously "Winlink" PMBO's at around 14075.2 and 
14075.6they come on even when there are strong signals on the freq 
so they must be auto and unattended..i believe these PMBO's use 
Pactor 3 which is a commercial program of SCS in Germany.i also 
believe that Winlink is a commercial program by the same company.
there was a RTTY contest on this week end.14076 was unusable as many 
RTTY stations just used what freq they liked...some of us qsy'd to 
18102 to see if we could get any VK to EU propagation..i put out a 
JT65A CQ and was immediatly clobbered by a very strong RTTY 
station.deliberate interference...by the look of his signal he was 
not calling CQ and there is no contests allowed on WARC bands any 
way.i continued to call CQ and he went away after about 5 minutes..
i agree Jack it looks like a mess and we ops have made it sothere 
has been some attempt to get areas for each one but once again there are

as the JT65 modes were initially mainly used on EME.
Either will constitute a good contact as long as RRR is exchanged. The 
73 exchange is not required for either EME or Terrestrial

and is really just a courtesy.
 
Usually you will see new stations both in EU and the US using the EME 
protocol until they have gained some experience

and or someone has explained how to send terrestrial signal reports.
 
Hope this helps.

*Subject:* [digitalradio] JT65A reports

There seems to be a difference btween reporting systems between the US
system and the European system on terrestrial JT65A contacts.

Can anyone explain to me when a contact is 'valid' between two stations
using the two different systems please?

For example, I received the following today (callsigns obscured to not
cause offence) on 20M

163700 12 -2 0.0 5 4 * CQ EA*** JM** 1 0
163900 10 -5 0.1 5 3 * G0DJA EA*** JM** 1 0
164100 6 -6 0.0 5 3 * G0DJA EA*** 1 0
164300 10 -15 4 3 RRR ?

That was it, no report, not even "OOO"s. I was using what, in the
guide, says is the European standard of sending the received dB signal
strength, but the EA station was using the US version, appart from no 
"OOO".


A quick read through the excellent Bozos guide gave me the clue that the
other station was double left clicking on callsigns (US system
reports)and I am double right clicking (Eu system reports).

Now, two questions occur to me at this point.
1. Is my EA contact 'good' or 'incomplete' and
2. What's going to happen when US stations and Eu stations work each 
other?


I wonder why two reporting systems were created for terrestrial JT65A?
My guess is that the US one will win out anyway, as that just seems to
be the way these things go and left clicking is more "the norm" than
right anyway, so why the alternative systems?

Also, whilst I'm asking questions, why does double right clicking
automatically turn Auto TX to ON? If you are not careful, and want to
pre-load a callsign to call at the end of an existing QSO, you end up
accidentally TXing over the top of the person working the station you
want to have a go at next. This seems a bit like poor operating and
it's not untill you do it for the first time that you realise what's
happening...

Thanks for any help with these problems I'm having - Dave (G0DJA)

 
Hi Barry..as far as i can tell the 73 exchange is still needed for a 
complete contact.
look in WSJT 6 Help "Examples of minimal JT65 QSO's" and both styles of 
EME and Terrestial
are shown.i understand there has been some talk about this with Joe 
Taylor and his statement is that the minimal shown is the way that it 
always has been on  CW or SSB
some ops are very fussy about the 73 and ive had them send it several 
times until they get a 73 reply.


hope to work you one day on JT65A 20 or 30 m

Listen to mineIt IDs in CW at the end of an unsucessful connect attempt

  I'm glad to hear that you are using a busy frequency detector, Dave. 
  The detectors in PK232 and SCS modems are certainly better than 
  nothing, but are quite limited. Neither detects PSK31 transmissions, 
  for example. As part of the SCAMP project, Rick KN6KB (a member of 
  the Winlink team) developed a soundcard-based busy detector that was 
  reported here to be very effective at detecting most modes found on 
  the ham bands today. I have repeatedly suggested that Rick's detector 
  be incorporated in WinLink PMBOs -- a straightforward and inexpensive 
  process -- but there has inexpicably been no progress on this front 
  for several years.

  Our HF amateur bands are a shared resource; no one can stake a claim 
  of ownership of any frequency or set of frequencies unless an 
  emergency has been declared. If contests draw more amateurs to the HF 
  bands -- as intended! -- then yes, there will be more congestion and 
  it will be harder to find a clear frequency on which to exchange 
  messages. Using HF amateur bands to offer a message passing service 
  with guaranteed quick delivery times is simply incompatible with the 
  defined usage model for these bands. There are techniques you could 
  use to optimize performance -- like QSYing to the WARC bands during 
  contests -- but nothing short of exclusively-assigned frequencies 
  would enable you to achieve a guaranteed Quality-Of-Service. I 
  personally don't think the assignment of exclusive frequencies to 
  specific sub-groups is consistent with amateur radio -- except during 
  a declared emergency.

Hi Everyone,

I've been following this debate for the past several days and finally have to 
add my two cents.

I'm part of NTSD, that's the National Traffic System Digital...We mostly use 
the old version of Winlink (before Winlink 2000) also reffered to as "Winlink 
Classic" running
Pactor I II and sometimes III... We used to use AMTOR and Clover but have all 
changed over to Pactor... Many of us are still using PK-232MBX's for Pactor I, 
others are using SCS TNC's All our connects occur in the automatic band 
segments... Winlink Classic has a very good "busy detector" in it... I've seen 
it work on not only Pactor, AMTOR, and Clover signals but other including RTTY, 
dead carriers etc...
Winlink classic when it hears another signal, postpones the connect and then 
tries 15 minutes later for a total of three attempts at a clear frequency.
I can tell you that with an active busy detector, our systems are almost 
helpless against RTTY signals that come into the automatic band segments 
especially during contests... Traffic thru put declines severely during these 
contests.

We're happy with staying within the automatic band segments with our 500 Hz 
Pactor I and Pactor II signals... It would be nice if others realized that the 
automatic segments do contain stations with "busy detector" armed and ready and 
please refrain from casual operation there, especially during a contest.

I know I'm going to get a lot of flack from those of you that don't like 
automatic stations, but like I said Winlink 2000 is  not the only Pactor 
operation around running automatically... We prefer to stay in the automatic 
band segments... Please have the common courtesy to respect our operations.

Re: [digitalradio] FCC: "Petition to Kill Digital Advancement"

Hi All..as this petition only has to do with Hams in the USA i would 
suggest that argument from both sides be taken to a group especially for 
the subject and not be put on the other many Hams outside the 
USA.this petition has already engendered some very bad slanging

Hi John.i run Kubuntu 7.10 herethats Ubuntu with the KDE

multidigi program available you can d/l at www.w1hjk.com.use the 
binary as it is easy to get setup.BUT read the Help file first you 
will need a couple of other libraries as well..you can also in a 
console type 'apt-get install fldigi' and you will get and early copy

if you have a problem please dont hesitate to e-mail me and i will give 
you a lot of help

Re: [digitalradio] Hearing impaired hams

[David]

Hi Andy..you are quite right ...i have had a problem with CW for 
many years due to hearing problems...tinitus in right ear and hearing 
loss in bothat times when a band is very noisy i also have trouble 
hearing ops on SSBthis is why i find digital modes are excellent for 
qso'sfor ragchew and dx i mainly use PSK and mainly on 20m...
recently found WSJT JT65A JT2 and JT4A and found that they are excellent 
modes when the band condx are poor..especially on 20m 14076..
i started on digital modes about 7 years ago when my xyl complained of 
the noise from SSB..earphones you say.yes but she didnt like hearing 
me using ham jargon either.
digital modes helped with this problem too.

Hi Andy.the only problem was that those of us that usually work WSJT 
JT65A on 14076 found that we couldnt due to the PSK63 ops on that 
freq.it was mainly EU stations that were the worst.it would be 
nice if some ops thought of other users of the band

[digitalradio] i think it was funny....

[David Michael Gaytko // WD4KPD]

last night while trying ale400 on 40m, one of the jerks with the wide 
pactor signal came up on top.
as i cursed the jerk in absentia, an  ale141a  signal came on and 
covered up the pactor !

possible moral..if one group of operators is allowed to get away 
with it, soon everyone will do it and
there go the bands for regular joe ham.

Hi Robert...thats a round about wayusually its Win programs being 
ported to Linux and you want to go the other way ;-) .as you can 
guess im a Linux opwe of course use Wine to work Win programs (if 
they will work)...the ECM .iso can be burnt to a CD and will work in any 
PC machine or a modern typeit has all the works on it...no need to 
put it on a h/d...if the CD is burnt with multi-session all settings can 
be burnt to the CD if used in a burner.
have fun

i may be wrong, but my $.02 worth asks how long before Home Land

[digitalradio] Im fed up

[David]

Hi All...I am about to unsuscribe to this group as im not interested in 
having my mailbox filled up with the constant argueing about "automatic 
stations" and there need for bandwidth and the opposite view that they 
dont need the space.its not that it may be a valid argument but that 
its got to the point that its clogging up a good group with all the 
slanging e-mails between 2 opinionseither the discussion is taken 
somewhere else or stopped before the group loses good operators like 
myself due to all the rubbish being sent out
No dont write to me by the time this has hit you desk i'll be gone and 
will not reply to any e-mails about this group

Sorry but thats the way I feel..i note too that the argument is mainly 
in ONE country..there are other hams worldwide who probably dont care 
about the arguing..

Hi Jose.in most Linux distros such as Ubuntu Fedora Mandriva etc 
there is a gui for setting the Date and Time under a Settings Menu.i 
use the KDE desktop so know that one well..i understand that the same is 
available under GNOME.in KDE it comes up with the GUI and you can 
set the automatic update of the time so that it uses a ntp 
server...there are some listed in the gui...the one i use is setup for 
VK and is useful if any part of the net goes down overseas.a list of 
the servers can be found by searching on the net.
I presume it does the same thing as Dimension4 does for Windows as i 
notice it uses a net time server
Yes this is done via a modem interfacing to the net...
i dont know of a way to do this via a radio and a time signal station 
such as WWV or WWVH...
Here in VK the HF time signal stations are very weak or not audible at 
times due to propagation and the fact there are none down under in the 
South Pacific.

Hope this helps ...any more questions im only too happy to try and 
answer.

i have been on hf/jt65a since its birthday.  while not knowing it all, i have 
never heard of a jt65a beacon or unattended operations. the mode COULD be used 
for a beacon just like the cw beacons run by the california group. 

jt65a can't operate unattended, the message operation must have an operator 
present to switch messages. pse don't include this mode with anything like 
winlink which does USE unattended operations for some portions of its program.

except for the obvious jerksit is mostly the contest sponsors fault.

iethis is a contest...do ANYTHING u wish to winuse ur amp if u 
got it/forget courtesy/forget that there be some non contesters on the 
band/etc.

its the sponsors RESPONSIBILITY  to control the contest parameters. it 
wouldn't be too much to ask for the sponsor to have at least one 
official station participate.  this official station could if necessary 
note rule breakers and dq the points, or possibly the whole entry by 
said jerk.

[digitalradio] xl spread sheet or similar ?

[David Michael Gaytko // WD4KPD]

hello all...a real programing dummy here.

my rotor display has broken.  the dc output to the formerly

@090', and finially [EMAIL PROTECTED]'. ie North centered.

i know i can calculate it every time, but this is the digital
age! looking for a brain to program a simple spreadsheet to
allow me to input the bearing and readout the mVdc so
i can use my dvm to set my rotor.

would be kind of nice to run it as perhaps a task bar applet
so would be there all the time, but i could do a onetime printout
also.

will someone help ?

[digitalradio] protocol for cq

[David Michael Gaytko // WD4KPD]

addendum...

as to the special symbol in the cq message, this would
allow you to tell if a station is calling cq, without having
to click and decode...

sort of like how distinctive a cq message is in cw, or ryry
sounds like in rtty.

david/wd4kpd

[digitalradio] protocol....cq on first only ?

[David Michael Gaytko // WD4KPD]

well of the bat seems ok, but once the conversation starts
the whole thing goes out the window.

maybe better if the jt65 code would have a special symbol
that would indicate a cq call.

that would be up to Joe i think.

[digitalradio] odd sounding jt65

[David Michael Gaytko // WD4KPD]

i know some of you have noticed some odd sounding
jt65a on the bands very slow and narrow by about 1/2.
at least it sounded like that, and no decoder in Multipsk
could decode it.

well today i fired up WSJT and sent some cq's.  my signal
sounded just like that, and i had not changed anything
in the program. finally noticed that the sound card error
that is monitored in the bottom left corner of WSJT showed
a tx error of 3.0, when of course it should be 1.0. i went to
the dos settings and checked, they seemed unchanged. restarted
WSJT, and problem cleared.

so if you can monitor you tx audio, keep an eye on the sound card
errors in WSJT.

[digitalradio] BIG DF OPERATING

[David Michael Gaytko // WD4KPD]

HEY GUYS DON'T TRY TO CALL A STATION THAT HAS
MORE THAN 100CPS OF DF FROM YOU.  IF HE IS LOOKING
AT +/- 200 OR LESS, HE IS NOT GOING TO DECODE YOU
AND YOU ARE WASTING TIME !

I WAS CALLING CQ TODAY ON 20M WITH MY TOL SET TO 200.
I DID NOT GET ANY ANSWERS AT FIRST, BUT NOTICED
ANOTHER STATION JUST ABOVE ME ON THE OPPOSITE
TIME SLOT.  JUST FOR FUN, I OPENED THE TOL UP, AND
DECODED THAT HE WAS CALLING ME, AND WOULD HAVE
BEEN A GUD DX CONTACT, BUT I MISSED IT.  HE SHOULD
NOT HAVE CALLED ME FROM SO FAR AWAY USING WHAT
AMOUNTS TO AN RIT IN EFFECT.

GUYS...PSE TRY TO TUNE TO THE SYNC TONE USING THE
RF DIAL, NOT THE CURSOR.

[digitalradio] help prevent qrm

[David Michael Gaytko // WD4KPD]

20m was a mess today, everyone planting on 076.

this is not necessary !  try this...

set in spectrum the jt65 DF axis option

freeze the program to 0, with tol to 200

tune whichever station you wish to tune by shifting
your dial to place the sync tone on 0

the 200cps tol will effectively give you a filter 400cps
wide around the other stations rf freq and it will not
decode anything outside the window, this eliminates lots
of qrm to you.  if you rig cant quite tune that close, when
most of the other stations tones are withing that window
you can re-freeze

the idea is to not use a large DF and take up more space
than needed, and spread everyone out a bit.

300cps is more than enough to ensure no qrm.

From: David Michael Gaytko // WD4KPD <[EMAIL PROTECTED]>
To: Harry Popov <[EMAIL PROTECTED]>

hello harry

well regarding the sideband issue, my understanding is that
it was done that way because of the technical limitation of
the mixer or sideband filtering method of the rigs back then would no
allow the lower frequencies to
maintain the mark high for RTTY.  i don't think there be any
modern rig today that has this problem. so now it is only because
of tradition that this is still done.  it could be changed.

as to the channels, with modern rigs 100hz is routinely done,
and all the stations i worked these past few days on wsjt
have all been well within this tolerance.  it seems that at
least trying would be better than taking up unnecessary
space by trying to qso with a very wide df.

just trying to help.
