Re: [digitalradio] Re: WSPR New Digital Mode - QSO Completed

[Jeff Moore]

AFAIK, the current release version of WSPR does NOT have the QSO capability in 
it.  What the message was apparently about was the first successful WSPR QSO 
using a beta version of the software with that capability.

I'm puzzled. When I checked the link, it seems WSPR is some kind of
automatic RX/TX connection reporting mode - Just reports what other
WSPR stations it "sees". That is, there is no back and forth QSO like
PSK31 and others. Did you actually have a QSO - chat back and forth -
with this mode or was your QSO just and automatice send/heard connection?
Thank you and 73,
Paul

My reading of the message is that Morse code is "authorized" NOT
mandated.  It seems a reasonable decision for a organization often
dependent on volunteers, if they want to use it.. let'em.  MARS will
continue to use MT63, ALE, PSK, and many other digital modes.

[digitalradio] Update: Digital Modes in 2008

[Andrew O'Brien]

Digital Modes in 2008: An Overview
   by Andy K3UK

To arrange QSOs or see a list of activity from these varying modes,
you are encouraged to try 

http://www.obriensweb.com/sked/  (click on digitalradio) 

http://www.projectsandparts.com/30m/

http://psk.gladstonefamily.net/pskmap.html

and join http://groups.yahoo.com/group/digitalradio/  for on-line
email discussion of how to get started in digital modes.



Common Modes
 

PSK31 , usually the easiest to get started.  Works well under most
conditions, MANY users.  Check 14070, 7035, 7070, 3580. 10140. 
Available in DM780, Winwarbler, Multipsk, MMVARI, FLdigi, MixW

PSK63:  Twice as fast (and wide in your waterfall)) as PSK31.  Great
for contesting and nets.  Not as good as PSK31 for weak signal
reception. Available in DM780, Winwarbler, Multipsk, MMVARI, FLdigi, MixW.

PSK125/250.  Good for VHF/UHF nets, file transfers, emergency
communication. Available in DM780,  Multipsk,  FLdigi, MixW.

RTTY:  Prone to the effects of propagation and occasional "gibberish"
is received.  Very common during contest weekends, the de facto
digital mode for contests.  Also used by many DXpeditions.  Not a lot
of "rag chew" QSOs, these months.  Check 14080-14100.  Available in
DM780, Winwarbler, Multipsk, MMVARI, FLdigi, MMTTY. Hamscope, MixW,
and many more.

MFSK16:  Performs "better" than PSK31 under weak conditions.  Not a
lot of users, can go hours without hearing a MFSK16 signal.  Can be
difficult to "lock" on to a signal at first. Some software
applications for this mode facilitate the sending of a small picture.
 Check 14072-14085, 10141.  Available in DM780,  Multipsk, MMVARI,
FLdigi, MixW.

Olivia:  Perhaps the "best" for weak signal QSO modes, Not a lot of
users, can go hours without hearing a Olivia  signal. Varying
combinations of tones can make it hard for a ham to determine which
variety of Olivia it is.  When conditions are really tough, this is
the one to try.  Check 14077, 14105-14110. 10141, 7077.  Available in
DM780, , Multipsk, MMVARI, FLdigi, MixW. 

HELL:  With the efforts of the Feld-Hell Club this "odd" mode is more
common that some of the aforementioned modes.  80 Meter Net  0300 Z 
Saturday 3.574.  NOTE NEW FREQUENCY  Net Control is  AC7XF Hugh
30 Meter Net  Z Monday 10.138.   Net Control is W8LEW Lew
10 Meter Net 1800 Z, Monday, 28.074.  Net Control is N3LFC Larry*
40 Meter Net 0200 Z Thursday 7073 KHz.  NOTE NEW FREQUENCY.  Net
Control is W8LEW, Lew.  This modes performs quite well bit not as good
 as PSK31, Olivia, and MFSK under average conditions. Requires good
eyesight for weak conditions.  Available in DM780, Multipsk, MMVARI,
FLdigi, Mixw. 

DominoEX :  Can be as good as it can get for weak signal detection and
QSOs.  Not a lot of users, can go DAYS  without hearing a DominoEx 
signal. As with Olivia, several varying settings add to dificulty in
determining which setting to use for decode.  Check 3581-4, 7077,
14077. Available in DM780,  Multipsk, , FLdigi, MixW

THOR:  Still an experimental variant of DominoEX, but may be more
common in the next few months.  Currently Alpha testing in FLdigi and
may be release with NBEMS.  Available in FL-Digi if an alpha tester.

ALE:  Gathering steams as a "mode" to be used for emergency
communications.  Can be very frustrating to set up, and even more
frustrating to get it to decode basic ALE digital formats. If used
correctly, for "automatically" establishing a link to another station
and then SWITCHING to a mode that matches conditions,  there is
nothing better !  Check http://hflink.com/  for MANY active
frequencies.  This one is not for the rookie, but can be a lot of fun.
ALE 400 within the software program Multipsk performs very well and
has LOTS of promise. Only two applications support SOFTware ALE,
PC-ALE and Multipsk.  Several expensive radios support FIRMware
applications of ALE.


MT63:  Used by some MARS stations, but you can go weeks without
hearing an MT63 stations on the hams bands.  Very good weak signal
decode, takes up a LOT of bandwidth.  Signal sounds like a low-toned
white noise.  Available in DM780,,Multipsk, MixW.


SSTV:  Used for sending pictures and text.  Very active used among
some hams.  Check 14230 for analogue SSTV and 14.233 for digital.
Check also 10.138 for narrow SSTV.  Digital variants of SSTV in such
software as Easypal are very efficient  . Analogue SSTV is available
in Multipsk, DM780, MixW, and MMSSTV. 

Throb/ThrobX.  Another one that does well under very weak conditions
but you can go weeks without hearing a station.  It sounds just like
it's name, a steady throbbing tone. It can be mistaken for JT65A or
MFSK8 at times.  Available in DM780,  Multipsk,  FLdigi.  Several
different "throbbing " rates .  


JT65A:  The best of them all for weak signal detection with evry low
transmit power needed.  Very active, many stations on the air with
this mode, worldwide.  Google the K3UK Bozo's Guide to JT65A for more
details.  This is NOT a

[digitalradio] Digital Voice Net Reminder

[Tony]

All,

Just a reminder about the Digital Voice Net on 14236.0KHz every Saturday and 
Sunday at 1800z. Mel, K0PFX is net control.

Check-ins for AOR fast modem users will begin at 1800z. The FDMDV net will 
follow immediately afterward.

Go to http://n1su.com/fdmdv/download.html for the latest release of FDMDV. 
Download the melp file http://f6baz.free.fr/FTP/DrmDv/melp_1400.dll and copy 
it to the FDMDV directory.

Go to http://tim-tom1.magix.net/ to hear Digital Voice Over HF recordings.

Re: [digitalradio] Re: CW - last resort?

[Rick W.]

I have to concur with Charlie. I did not see anything negative in the 
MARS reappraisal of CW. In fact, it seemed bizarre and counterproductive 
to me when they decided to not only drop CW, but to prohibit its use on 
MARS channels some years back!

I do agree that there are almost no new hams who are willing to do the 
work necessary to become proficient with CW. Of all the classes I have 
taught over the years, mostly entry level Technician and more recently 
several General classes, I can not recall any of my students ever going 
on to learn CW.

When I commented on this to our STM a year or so ago, he pointed out 
that while things were not going all that well with the Section 
Intrastate CW nets, the growth area was actually in the entry level CW 
nets. Back in the early 1980's when I got relicensed, I was quite active 
on the WNN (Wisconsin Novice Net) and WSSN (Wisconsin Slow Speed Net) 
and was even WSSN NCS for a year or so on Monday nights. We had about as 
many QNI then as now, so maybe there will be a few new replacements? Or 
maybe that is wishful thinking?

Based on the comments by David, he does not seem to understand that CW 
really can get through when other modes can not, and that includes most 
of the digital modes.This is especially true if you consider the 
bandwidth used. And when you are in an emergency situation, you may have 
a telegraph key or can figure out a way to key the rig, but you may not 
have the computer necessary for most digital modes.

There may be a few digital modes, that can compete with CW under extreme 
conditions and can operate with faster throughput. But there are very 
few traffic nets or emergency nets that seem to do this. None in our 
Section even though I have talked it up from time to time. The ARES 
"leadership" wants all digital to move to only Winlink 2000 so digital 
activity has not progressed well except perhaps in the more heavily 
populated areas.

I can not even get new hams to operate machine CW, even though they have 
the privileges now to operate on 80/40/15/10. But then again, almost 
none of them will operate SSB or digital on 10 meters either:(

[digitalradio] How to choose Olivia tone/bandwidth parameters -- an idea

[Ian Wade]

Here is an idea that Olivia developers might care to consider.

People often remark that it's difficult to set up the right parameters 
when receiving Olivia signals. There are potentially eight possible tone 
settings to choose from (2, 4, 8, 16, 32, 64, 128 and 256 tones) and 
five possible bandwidths (125, 250, 500, 1000 and 2000 Hz) -- a total of 
40 possible combinations -- making it almost impossible to choose the 
right combination before the signal disappears.

Out of these 40 possible tone/bandwidth combinations, there are probably 
up to 8 that are in popular use: 4/250, 4/500, 8/250, 8/500, 8/1000, 
16/500, 16/1000 and 32/1000. Even so, narrowing the choice down to these 
8 still takes too long. What is needed is a simple way of indicating 
which combination is in use at the start of transmission.

This is where we can make use of the capability to display text 
characters in the waterfall. If we allocate a code for each 
tone/bandwidth combination, and display that code as text in the 
waterfall immediately before transmitting the Olivia signal, it will be 
possible to set up the correct parameters very quickly, in time to 
decode the signal.

A possible coding scheme could be as in the table below. The most 
popular combinations are indicated with asterisks.

Each code is preceded by the letters "OL-" (for Olivia), to identify the 
mode. So, for an 8/500 signal, you would see the characters "OL-12" in 
the waterfall before the Olivia signal starts.

OL-37   256  500
OL-38   256 1000
OL-39   256 2000


This idea could even be extended to other modes, substituting a 
different code in place of "OL".

I believe that Olivia is greatly under-utilized because of the 
difficulty in choosing the correct tone/bandwidth parameters when 
receiving a signal. Being able to select the parameters quickly by 
reading the code in the waterfall should go a long way to promoting more 
Olivia activity.

Comments anyone?

I guess it's time for us all to learn how to build spark gap
transmitters, just in case.

You see the bandwidth already - so why not just OL + number of tones?

I don't think users will like a lookup table.

That's exactly the correct reading. Another tool for the toolbox.

Digital modes (ranging in complexity from WL2K and ALE down to PSK31
and RTTY) will carry the bulk of the traffic.  But if the computer
goes down and propagation stinks, CW certainly beats "nothing".

[Jose A. Amador]

Interesting, but I believe it has already been done in MultiPSK with the 
RS ID codes sent in MFSK in the preamble. They seem to work well.

I have used Video ID's and maybe your proposal is a bit more compact and 
readable that the usual video ID's. It should be tested out. I believe 
tha making Olivia more popular is a good thing.

Just some more food for thought.

I am crossposting this to the Olivia and MultiPSK groups from the

Even when I have nothing against DV, people have to recognize that it is 
not a QRP activity. I see quite a few signals I can never decode because 
they do not exceed the threshold.  FDMDV is not PSK31.

To: [EMAIL PROTECTED]


Another good turn out for the nets this weekend.  Thanks to the
following for participating:

N1FFX/mobile, K2MO, K6KAR, W7KEV,K4RG,KC3OL,WB8EJN, AC5IU,
W4ROS,KG4MUW, K4KR, N2KBE, WA5QPZ, K3DCC, W0TFF, K4MIA,W5RRR and
WB5USB.

And we welcome NB2I, John from NJ on FDMDV first time in the nets.
John was an early adopter of the AOR9800 so glad to see/hear him
trying out this mode as well.  N1FFX is running mobile on his way to
Florida and made several contacts from his mobile station.   Running
DV mobile is quite a challenge so congratulations Gerry for being the
first mobile to check in the nets. Gerry was using a Bluetooth headset
and took advantage of the pc "space bar" for PTT control.  It was
interesting to note that not a lot of "multipath" was observed in the
waterfall, however typical for mobiles, deep fades were evident as the
terrain was constantly changing.   Propagation on Sunday overall was
pretty good with both short and long hops.  It is rare that I can copy
Oklahoma stations, but Sandy WB5RRR was quite strong with SNRs in the
teens/signals S9+.

New Mexico is not only the "Land of Enchantment" but also the land of
DV all centered around Albuquerque that includes K3DCC, KB5XE, AC5IU
and WB5USB.  You guys could start your own local DV club!  :-) Good to
see all the activity from the SW.

Sorry if I missed any one, if so.. I'll look for you later nets.

One last note... I had an interesting QSO on 14.236 around 0200 UTC on
1 June (Saturday night).  I heard JA3ILI in Japan calling "CQ" with an
S9 plus signal and very good audio using the AOR9800 DV box.  The freq
was clear and "Harry" and I had a good QSO.  It turns out that Harry
was using an internet link and running remote using W6AOR's club
station.   Remote operation is been done using FDMDV by K6KAR, K3DCC,
KB5XE and others on FDMDV.

Are you suggesting calling CQ in a different digital mode than Qlivia,
then switching over?  If the listener can read the (Olivia) "Text"
then they are already reading at the proper BW/Tone??

Could be true Chuck. I guess to take it just a step further, we need 
to ask Simon to start looking into writing another mode into his 
great software to decode/operate the hammers to hit the trees like 
the old natives in the jungle do.  

Oops, somebody would have to go cut down trees and the "huggers"

Oh wait! This even predates CW and was just as effective . hmm

Perfect!  Just as the US is moving back to AX.25 packet technology for Emcomm 
purposes, people are planning on "shutting down" and making wholesale changes 
to the AX.25 protocol.  Brilliant!

Hopefully, it will only affect the VK crowd.

Re: [digitalradio] Re: How to choose Olivia tone/bandwidth parameters -- an idea

[Jose A. Amador]

Paul,

Some programs are capable of sending a "Video ID" using Hell, so, you 
can read the ID as a text preamble from the waterfall.

MultiPSK also does send a RS ID using some codes sent as an MFSK 
preamble. FDMDV now does use the RS ID too, to help "zero beating" on 
the spectrum center.
