Re: [digitalradio] RTS for PTT interface Re: PC-ALE

[Erwin Jabor]

Hi Bonnie,

Sorry for asking an OM. It is so usual hi.
Well I was trying it without success, BUT finally I found the problem. The CAS 
interface was connected in the software to com2. I dont have a com2 so I get an 
error about this. When I just putting the CAS to com1 (the same I use for RX/TX 
switching it works fine. Thanks for your fast response.
Will be surpriced when I can make the first qso. Will be active in the next 10+ 
day's.
vy73 and have a fine Day.

[digitalradio] RTS for PTT interface Re: PC-ALE

Dear Erwin,

Try using only one method for hardware PTT:
RTS for PTT
-or-
DTR for PTT

Do not use both at the same time.

Be sure your hardware interface has the same 
selection as the software.

There is one more factor to consider:
What type of interface are you using?
Does your interface get relay power from the DTR line?

Sorry if I'm not an "OM", Erwin, but I hope that my 
suggestion will help you to find a possible solution anyway :)

[Erwin Jabor]

Hi Om's.

I'm new to PC-ALE. I use an ALINCO-DX70 for PSK31 without problems. At the 
computer I use the 2 handshaking signals on com1 to switch the TX-70 from TX to 
RX. Works fine. I was trying the same with PC-ALE. I can see the audio on the 
display, but I cannot switch to TX-Mode. Have set it in the config to com1 and 
flagged the two handshaking signal on, but what ever I do I cannot activate the 
TX. I'm shure for 100% that I'm doing someting wrong, but what ?
Every help will be appreciated.

Erwin, DU1MGA

[digitalradio] 14100.5 and 14112.0 kHz Re: RFSM8000

[expeditionradio]

Hi John,

The 188-110 and RFSM activity is common 
on all the ALE channels. Often, it is 
convenient for operators link on an ALE pilot 
channel, such as 14109.5, and then QSY to one 
of the other ALE data freqs for traffic. 

Here are the freqs that are normally used 
for RFSM or 188-110: 

20 meters:
14100.5 USB 
14109.5 USB
14112.0 USB <<< active
14346.0 USB < image 

30 meters:
10136.5 USB
10145.5 USB 

40 meters:
7040.5 USB
7065.0 USB
7110.5 USB <<< active 
7185.5 USB < image

80 meters:
3584.5 USB
3617.0 USB
3845.0 USB < image

Re: [digitalradio] On PSK31 versus other modes

[Rick]

Consider that voice SSB requires over 2000 Hz for reasonable quality and 
2700 Hz would be better. Speaking on the air may be about 120 wpm. That 
figures out to around ~ 20 Hz per wpm, give or take some. For passing 
traffic it would be much slower though with more Hz per wpm.

PSK31 is about the narrowest mode available to communicate at that 
speed. Even CW may be around the same bandwidth (~ 60 Hz). This allows 
enormous numbers of hams to set their dial frequency at one point and 
must move their cursor to read out or even contact or call other hams.

PSK31 can be sent at an average speed of around 40 wpm in that 60 Hz 
bandwidth, or 1.5 Hz per wpm. If you only look at throughput per 
bandwidth you find that if you need high speed, robustness, and 
accuracy,  nothing can touch Pactor 2 and 3. If you need keyboard speed, 
then it likely be a different story.

Scaling different modes, under moderately good conditions and using 
Patrick's Multipsk information and some averages with ARQ modes from 
KN6KB's RF Footprint Powerpoint:

Mode   bandwidth (Hz)   /   speed (wpm) = Hz/wpm

Olivia 32/1000 -   1000 / 24 = 42

ALE MIL-STD-188-141A - 2000 / 76  =  26

Olivia 16/500 - 500 / 20 = 25

Olivia 8/1000 1000 / 59 = 17

FAE = 2000 / 150 = 13

MT63 1000 / 100 = 10

45 Bd RTTY 600 / 60 = 10 (some will consider this narrower and with a 
better score)

MFSK16 - 316  / 42  = 7.5

Pactor 1 200 / 600/200 =  3

ThrobX - 94/40  = 2.3

DominoEX/11 194 / 77 = 2.5

PSK31 60 / 40 = 1.5

Pactor 2 700 / 500 = 1.4

Pactor 3 2400 / 2225 = 1

If you adjust some of the numbers for conditions where the S/N is well 
below zero dB, then I think it would change things a bit. Some of these 
numbers are guesstimates so if anyone has other suggested numbers, it 
might be interesting. The main thing is to look at the relative 
comparison. But we need to keep things in perspective, since all things 
are not equal and a wide footprint mode for keyboarding would be 
difficult to justify unless it had special abilities to handle difficult 
conditions as some of these modes have. I could do another SWAG on this 
with say, -5 or -10 S/N.

RE: [digitalradio] RFSM8000

[John Bradley]

Tnx fer the note, Howard

 

Over the next week or so ,we should have VE5GPM up and running 24/7 on RFSM
8000, not beaconing, but ready to receive calls and transfer files.

 

VE5TLW and I will be working on learning the software and making a little
noise with same. I think we will find an alternate frequency to play on
since

14109.5 is busy with ALE soundings ,and will let you know what it is.

 

To that end would welcome input from the US ham community since this is a
more critical issue south of the border than here.

 

I THINK that you are able to use the non-standard modulation which is 2.4khz
wide , as opposed to the Mil Std 188 which is 3khz wide.  You should be able
to copy any packets in the Packet window.  

 

Again , get some opinions from others in the US as to whether this is legal
, and where in the US band plan it could be used.  At first blush , it
certainly has some promise.

RE: [digitalradio] On PSK31 versus other modes

[John Bradley]

 

Hey, don't get me wrong, I am also active with PSK31 and RTTY, and regularly
use each, sometimes even in contests since there are  not

A lot of VE5's on either mode.

 

The tuning difficulty on some of the early "newer" modes, particularly MT63
and to a lesser extent, MFSK was certainly very true. 

However Pavel, Patrick and others have made the newer modes such as Olivia
very easy to tune, as easy as PSK31 in fact.

 

I am not suggesting for one minute that we turn our backs on older modes
such as RTTY and PSK31, but to keep an open mind and keep trying

The new modes as they surface, and form your own opinions . 

 

Ham radio has a long history of experimenting.

Dave, an interesting point. I was going to post about PSK31 last week
but forgot to get around to it. The gist of my thoughts were
essentially the same as yours...that is...after all the myriad of
other digital modes, PSk31 is amazingly dominant and well utilized.
After hours of looking for MT63 and Olivia last week (for a test) I
would assume the 40 or 20M bands were dead, then remember to tune the
PSK31 areas and found dozens of signals , almost 24 hours per day.

I was going to post something along the lines of "back to basics" and
encourage some of the experimenters to not forget PSK31. I am now
testing as new software release from G3PLX, I doubt that it will
replace PSk31, but then again I was skeptical about Steve Fords' old
QST article suggesting that PSK31 would supplant RTTY...Steve was
right.

So folks, I agree with Dave. While I love experimenting with new
modes, I do not want to suggest that this group somehow looks down at
PSK31. I use it regularly.

[digitalradio] A word from the owner

[Andrew O'Brien]

Each January, I publish the list rules.  The primary rule is that we
avoid personal attacks while encouraging vigorous debate of topic
associated with amateur digital radio.  Most of the time, the rules
are followed and I have very little do do.

  The other day, i saw a post that John VE5MU posted and it singled
out a AA6YQ on an issue.  My first instinct was to step in and remind
people of the basic rule.  Knowing John VE5MU, I then decided that
perhaps I misunderstood the context of his remark and thus I took no
action.


Upon return from the office this evening, I see that others have
reacted to VE5MU's post and some personal issues have emerged.  looks
like my first instinct was correct.  I am sure that John VE5MU meat no
real "dissin", but context within an email is often difficult to
discern.  So, I apologise to the group, I should have addressed the
matter in a friendly way and asked for the tone to be turned down a
tad.

Here is an except from the rules...


This group is uncensored. Members are free to engage in the posting of
information, solicit answers to questions, and engage in lively
discussion.

Expressions of diverse opinions are encouraged. However, expressions
of opinion should
be non-judgmental and devoid of personal insult. For example : You can
say " I really
disagree, and I think your view is totally wrong" but should not say
"You are a jerk,
and obviously have the I.Q of a mole".

Racist remarks, or remarks intolerant of the diverse cultures found
within the amateur
 radio community, are not allowed.

The expression of fraternal greetings associated with varying holidays
celebrated around the world are NOT prohibited.

The use of swear  words is discouraged.

Please try to avoid endless debate of a topic. Make your opinions
known by all means,
respond to counterpoints a couple of times too, if you want. However,
after a while debates
often turn in to endless circular arguments. When this happens the
moderators will occasionally "end the debate" by giving a 72 hour
notice. This means after 72 hours notice, posting on the topic should
end. Occasionally, a "cooling off" period is enacted whereby the list
is  placed on fully moderated status to allow the debate to cool of.
In 2006 for example,
this happened three times.

Sanctions:

The goal of this group is that no member will be removed or banned simply
 because they expressed an idea. Only one member has ever been banned
If you post or
reply to a message that is considered clearly inappropriate, you will receive a
friendly message from the Moderator. If you continue to send
inappropriate messages
you will receive an official warning. If the offensive posting
continues you will
placed on moderated status for at least 30 days. Repeat of such actions after
removal of moderated status will result in a one year ban from this group.

The posting of pornographic messages or pictures (to Files section) will result
in an immediate ban

Andy,

I've noticed they are trying to give the appearance that they have
moved to bandwidth-based bandplanning, but they still adhere to mode
descriptions and categorization. 

Sadly, they simply copied the IARU Region 1 bandplan, along with many
of the poorly-planned parts of it. It is out of place in Region 2.
International normalization is good  in some cases, but not when it
happens in a negative direction. :)

The use of 200Hz limit bandwidth is totally unrealistic for anything
except PSK31...  and if you notice, they did not apply 200Hz to the
worldwide PSK31 window at 14070-14073 kHz! CW operators normally do
not operate within 200Hz of each other, except for CW contests. 

They copied Region 1's limit of 2700Hz bandwidth. It is rather
unrealistic, considering that many SSB voice tranceivers have 2.8 or
3.1kHz filters. Oh, and did you notice the wacky "AM exception"?
 
The 80m, 40m, and 30m bands in the plan are vastly out of touch with
the reality in Region 2. In fact, they are in direct contradiction to
USA's FCC rules. They somehow missed the fact that USA operators are
95% or more of the operators in Region 2. Didn't any of the
bandplanners notice the elephant in the room?

Perhaps they need input by more active digi operators over the next
few years when they get around to making a new bandplan. It looks like
they totally ignored the input they received over the past year. In
the mean time, they missed the digitization trend on the air, and the
way that the bands are being used by operators on the ground. 

By being out of touch with "ground truth", we can expect that large
parts of the Region 2 plan are going to be widely disregarded by
operators in North America. In fact, they must be disregarded in some
cases if operators follow their own country's ham regulations. 

This is a tragedy, because this sort of "head in the clouds"
bandplanning breeds overall contempt by the rank and file for bandplans. 

As usual, the various world bandplans, including the new IARU Region 2
bandplan are on the HFLINK.COM bandplan site:

By your own admission, your operating experience with digital modes

cost; hams are naturally inquisitive, and can easily download any of
several free soundcard applications to run Olivia, Dominio, ALE, or
whatever new flavor of the month that Patrick F6CTE has concocted.
The development of new modulation techniques and protocols is useful
and important, and may some day bear fruit. But so far, no one has
developed a protocol sufficiently better than PSK or RTTY to
instigate any significant migration. Might these new modes be better
than PSK or RTTY in one or two interesting dimensions; sure, but then
they're either too difficult to tune, or consume too much spectrum,
or don't work unless the SNR is unrealisticly good. I and many others
who have listened to MFSK, MT-63, Throb, and Hell QSOs found no
reason to go further. Like anyone else, hams vote with their feet.

I challenge you to try some of these new modes, and I and others would
welcome your opinion of these new technologies.

>>>I have, and just did.

At the same time would encourage you to put some of your considerable
technical ability into developing busy frequency software In
cooperation with one of the authors, rather than simply complaining
about it at every opportunity.

>>>I have no interest in operating an automatic station, or
connecting to an automated station to send messages. If others want

suggestions from the DXLab community; that's where I'll be spending
my time.

>>>When the "WinLink doesn't listen before transmitting" issue first
exploded, I signed up Peter G3PLX and Bob N4HY to work with me on
developing and implementing a new shared-channel message-passing HF
protocol with busy frequency detection that WinLink could use instead
of Pactor 3; Bob presented our thinking at a DCC a few years back,
but the WinLink folks made it very clear that they would never move
to anything not of their own design. Too bad, because Peter had some
promising ideas for error detection/correction, and Bob was chomping
at the bit to employ trellis coding. I then spent some time on the
phone with Rick KN6KB, encouraging him to add busy detection to
SCAMP. At the time, Rick feared that anything less than perfect
performance would be unacceptable, but I helped persuade him that an
80-20 solution would be an immense step forward. His first-cut
implementation performed far better than either of us expected.

>>>My postings here are not complaints. They are rebuttals to bogus

targeted at you or your friends, John; that'd be a waste of time.
They're aimed at newer hams who might not yet see your position for

Dave, an interesting point.  I was going to post about PSK31 last week
but forgot to get around to it.  The gist of my thoughts were
essentially the same as yours...that is...after all the myriad of
other digital modes, PSk31 is amazingly dominant and well utilized.
After hours of looking for MT63 and Olivia last week (for a test) I
would assume the 40 or 20M bands were dead, then remember to tune the
PSK31 areas and found dozens of signals , almost 24 hours per day.

I was going to post something along the lines of "back to basics" and
encourage some of the experimenters to not forget PSK31.  I am now
testing as new software release from G3PLX, I doubt that it will
replace PSk31, but then again I was skeptical about Steve Fords' old
QST article suggesting that PSK31 would supplant RTTY...Steve was
right.

So folks, I agree with Dave.  While I love experimenting with new
modes, I do not want to suggest that this group somehow looks down at
PSK31.  I use it regularly.

of Pactor 3; Bob presented our thinking at a DCC a few years back, 
but the WinLink folks made it very clear that they would never move 
to anything not of their own design. Too bad, because Peter had some 
promising ideas for error detection/correction, and Bob was chomping 
at the bit to employ trellis coding. I then spent some time on the 
phone with Rick KN6KB, encouraging him to add busy detection to 
SCAMP. At the time, Rick feared that anything less than perfect

Re: [digitalradio] RFSM8000

[Howard Brown]

John, thanks for the consideration today.  I have been and 
am still listening on 14.109.50.  I did hear one burst a while
ago but mostly just hear ALE.

BTW I just want to try to copy beacons since I still believe
it is not legal for me to transmit here.  I should be able to
copy the beacons and see them in my packets monitor 
window, right?

I am looking for people in range at VHF to test with here.
It is amazing what can be done on 2 meter SSB.

RE: [digitalradio] ALE , J65, Pactor 1 thru ?, etc.

[John Bradley]

 

First of all , I am not a "propeller head" and am the first to admit so.  My
technical ability is limited to firing up my computer, installing whatever

Software developed by people much more talented than I am, and using it on
the air.

 

I am heavily involved in emergency communications, hence my interest in
digital modes. I teach emergency management and communications, 

Search and rescue team leader, and search management courses . I am a
participant in all emergency training activities in our province, and have
been called out numerous times to assist Fire Police and EMS over the past
15 years . I work under contract to the City of Regina, as the Director of
Emergency Social services, co-ordinating the efforts of the City, Red Cross,
Salvation Army, and private sector contractors to provide shelter for those
unfortunate folks displaced by disasters. I have written and number of
articles on Search and Rescue, as well as a SAR needs analysis for
Saskatchewan Justice and the Royal Canadian Mounted Police.

 

My interest in these modes are to adapt them to emergency communications in
our Province, in conjunction with ARES, so that we can rapidly pass traffic
from remote locations to EOC's and reception centers. Our geography and
population base makes the need for radio amateur communications an essential
service using VHF, HF , and the internet.  We have adopted several of these
modes already and are looking forward to the development of an ARQ mode
which will allow us an internet gateway without the need for an SCS modem. I
and several other VE5's happily test these modes under a variety of
conditions and provide feedback to the authors.

 

I am also a "hard-core" rag chewer, and really enjoy getting on the air with
one of these new modes and shooting the breeze, and am able to do so at the
bottom of the solar cycle, and a very modest station, using the new digital
modes.

 

By your own admission, your operating experience with digital modes has not
progressed beyond  PSK31.  There have been many improvements since then with
people like Simon, Patrick, Pavel, Dmitry and many others pioneering new and
very effective operating modes, some of which are proving to be almost as
effective as CW in poor operating conditions ( as an example, Olivia) . 

 

I challenge you to try some of these new modes, and I and others would
welcome your opinion of these new technologies. At the same time would
encourage you to put some of your considerable technical ability into
developing  busy frequency software In cooperation with one of the authors,
rather than simply complaining about it at every opportunity.

First, John, I will point out that you have never provided a serious
technical response to any of the points made regarding the importance of
listening before transmitting, and the opportunity to enable polite,
unattended operation via busy frequency detectors. You mostly snipe and make
lame personal attacks, like this one.

 

My primary log contains 22 keyboard-to-keyboard Pactor QSOs, ~500 PSK31
QSOs, ~150 PSK63 QSOs, and more than 2100 RTTY QSOs; I have 319 countries
confirmed on RTTY. During operations from KH6, KP2, FJ, and V4, I've made
another couple of hundred PSK31 QSOs and more than 600 RTTY QSOs. If you're
so active, why aren't you in any of my logs?

 

Besides DXing, I spend a fair amount of time developing and supporting
WinWarbler, a member of the freeware DXLab Suite whose logging and
transceiver control components are also used with MixW, MultiPSK, and DM780.
I've also been supporting the ADIF specification for the past couple of
years -- the standard used for interchange among logging applications and
services like LotW and eQSL.cc.

 

What's been your contribution, John?

Hi Andy,

I will put Hong Kong on the air for this year's 
ALE QSO party. Look for soundings by VR2KQ6XA, 
since there are no "/" in ALE callsigns.

There have been a few comments from those who 
noticed the 10-day week. It really is one UTC week,

Mid-October is typically a good time for propagation. 
Fortunately it doesn't overlap with any major

Re: [digitalradio] Ale

[Steve Hajducek]

Hi David,

I know of no *nux based native application that has been offered to 
the world yet as ready for use. There is a package for developers 
that Charles Brain and another fellow placed on SourceForge under GNU 
called LinuxALE that dates back over 5 years now, which I have not 
seen anyone make use of yet as to developing a *nix application.

A number of MARS members are running MARS-ALE under WINE, here my 
Linux boxes are not up to doing so as they are all older IBM PC 325 
servers, two for IRLP nodes running Red Hat 6.2 that I really need to 
go and update, one is a 7.3 box and the other is a 9.x server, but 
nothing above 300Mhz. Since I got back into programming I have only 
been developing code for MS-Windows, although I keep thinking about a 
Linux box as a stand alone modem/controller to select for use by 
MARS-ALE, were said box would have no GUI, it would just be a 
modem/controller, a monitor, keyboard and pointing device would not 
even be needed. Then again, I also think about a RTOS on a single 
board CPU or MCU modem/controller as well, its just the price point 
of such new and time all around to make things happen.

Re: [digitalradio] Busy Channel Detection

[Rick]

Thanks for confirming  this, Andy,

When I monitor the ALE frequencies, particularly the 14109.5 frequency, 
I do hear a fair amount of ALE throughout the day, and sometimes other 
modes. I admit that the stations that I am hearing are the same ones 
over and over and over. Generally speaking there are maybe 20 or 30 
discrete callsigns that come up.

Contrary to comments made by Bonnie, KQ6XQ, she does not own these 40 
"channels" on HF that she is claiming for ALE use only with her 
outrageous comment that:

"It is likely that anyone who says they are getting their keyboarding
QSO clobbered by ALE is intentionally provoking trouble by purposely
operating in the automatic sub-band, right on top of the active ALE
pilot freq"

Others have used this frequency for wide bandwidth modes for quite some 
time. It was even published long before any ALE operation.

Some how these scofflaws need to back off a bit and rethink what the 
amateur bands are all about ... which is shared spectrum. Not shared for 
one mode, but shared for everyone.

Rick, KV9U

Hi Rick,

I've discovered last week that we cannot in Canada transmit wider than 1 
kHz on 30m. It's a shame. This band is often in those poor conditions months 
the only one opened to mid distant stations and as an HFN pilot station 
operator, that's a real problem for me and the stations that want to link to 
my station because sometimes it's the only they can link and in this band 
only due to conditions. So after sounding for 2 full months on 30m, i only 
scan it now.

John,

About the last person on earth that I would criticize for not operating 
would be Dave. I have no idea how he can do what he does with the 
creation and support for his DXLab suite of software which includes 
digital software as well. It is simply amazing.

But even if any ham rarely operated on any modes, but mostly monitored, 
they would know quite well what is going on.

Proper operation is very important to some of us. And the rules that 
hold true in one country, may not hold true in other countries. In fact, 
a group such as this one can help us understand that. It was only in the 
last few days that many of us even knew that some hams cannot use wide 
bandwidth modes on 30 meters that we can use here in the U.S. and you 
probably can in Canada.

Re: [digitalradio] Keeping Olivia in mind

[Simon Brown]

I can only confirm Andy's findings - Olivia will decode well even when the 
signal is neither audible nor visible.

Pawel's 2006 code base is a remarkable feat of programming, I have taken 
Pawel's code and reformatted it into more standard C++ classes (Pawel used 
very heavily templated code). All encoder / decoder code is shipped as 
Visual Studio 6.0 DLL's with DM780 kits.

Gee, Bonnie all that flying to Asia has stretched your definition of a
week to 10 days in a week, I like it.  I will be ALE active during the
period and look to see some new callsigns on my screen.

[digitalradio] Keeping Olivia in mind

[Andrew O'Brien]

I wish to keep Olivia in our minds and operating practices.  A new
releases of DM780 with Olivia may be out soon and perhaps bring a few
new users.   Multipsk and MixW already have Olivia.  While beta
testing DM780,  I have made an effort to work more Olivia and I am
reminded just how remarkable this mode is at digging out signals.
Last night I was on 160M with extreme local line noise , no audible
Olivia signals, and nothing that I could discern in the waterfall.  I
noticed a string of CQs and a callsign a on my screen.  Since the
callsign looked familiar,  I assume i had discovered an oddity in
DM780 and DM780 was somehow still displaying a CQ string from the
previous day when i was copying PSK31.  I have good ears for very weak
signals (from my old SWL days of listening for Radio Tistan Da Cuhna
on 90M) , and would have insisted there was no signal present.  I was
in the middle of whisking off a email to Simon about the DM780 oddity
when the CQ string scrolled across the screen and I was able to tell
that I was copying a live signal.

So, with the HF propagation conditions being quite poor , we have
established ALE as a very useful method of communication since Steve,
Charles, and Patrick added improvements to the software.  We should
now perhaps remember to add Olivia to our bag of digital tricks, it is
quite simply the best for most weak signal conditions.

[digitalradio] ALE On The Air Week: 05-15 October

[aotaw2007]

ALE On The Air Week: 05-15 October
(Please forward and distribute)

AOTAW (ALE On The Air Week) is an annual International Amateur Radio
event sponsored by HFLINK, a resource for ALE, HF Interoperative
Communications, and HF Emcomm. Ham radio operators worldwide are
invited to participate in a 10 day readiness event of ALE HF activity
on the air. AOTAW-2007 is an excellent chance to explore ALE
communications.

Start: 0001 UTC Friday 05 October
End: 2359 UTC Monday 15 October 

Thousands of amateur radio operators worldwide have ALE capability
now, using HF ham transceivers and computers running PCALE software,
Multipsk software, or commercial ALE HF transceivers adapted to ham
radio ALE use. The experience gained by operator participation is also
useful for HF Emergency / Disaster Relief Communications.

What Is ALE? Automatic Link Establishment. In the hands of a skilled
HF ham operator, ALE is a force multiplier. With the capability to
call up a specific HF station, a group of stations, a net, or a
networked station, ALE is a versatile digital calling system for
initiating and maintaining QSOs with SSB voice, data, text, instant
messaging, internet messaging, or image communications. 

Each ALE station uses the operator's callsign as the digital address
in the ALE controller. When not actively in communication with another
station, the transceiver constantly scans through a list of
frequencies in multiple HF or VHF bands, listening for its callsign.
To reach a specific station, the operator simply enters the callsign
just like dialing a phone number, and transmits a short digital signal
burst. When the distant scanning station detects the first few
characters of its callsign, it stops scanning and stays on that
frequency. The receiving station, which was muted up until now,
typically emits an audible alarm and visual alert for the receiving
operator of the incoming call. It also indicates the callsign of the
linked station. The two stations' ALE controllers automatically
handshake to confirm that a link is established and they are ready to
communicate in any mode, such as SSB voice, text or image. All of this
happens quite fast, usually within a few minutes.

A unique ALE Operator Certificate is available to operators who
participate in AOTAW. To qualify for the certificate, the operator
simply completes at least 5 QSOs through Automatic Link Establishment
communications on HF or VHF. The initial ALE linking QSO can use SSB
Voice or "AMD" Text Message (the standard text messaging format in all
ALE systems). See AOTAW Guidelines and Details. 
http://hflink.com/aotaw

Additional certificate endorsements are issued to operators who link
with 25 stations or more, or send 2 ALE-SMS text messages through High
Frequency Network Pilot Stations.

ALE High Frequency Network (HFN)
The HFN Pilot Stations are equipped with scanning ALE transceivers,
multiband antenna systems, and special software control systems for
internet connectivity. Ham radio ALE users in the field on HF connect
with the HFN Pilot Stations to exchange digital ALE-SMS text messaging
to and from internet devices such as cell mobile phones, black berry
type devices, PDAs, PCs and laptops. The free service includes:
HF-to-Cellphone message
HF-to-email message
HF-to-HF message

All HFN stations automatically exchange signal reports with each other
every hour on every HF band, and all this ALE HF activity with signal
reports and messages is displayed in real time on the web at ALE
CHANNEL ZERO:
http://hflink.net/qso

Organized ALE ham activity began about 6 years ago, when a group of
operators started working together to experiment with various methods
of HF selective calling on HF. The need to call up emergency nets or
inter-operability and liaison with government HF systems led many hams
to adopt the government ALE standard, called FED-STD-1045 or MIL-STD
188-141. This standard caught on slowly in the ham community,
initiated by a few operators with limited government surplus gear and
some with expensive commercial equipment having embedded ALE or
hardware controllers. They adapted the system into what has come to be
known as Ham Friendly ALE, which includes ham-specific programming and
use of frequencies in the automatic subbands. Now, with a ham HF
transceiver, a computer as the controller, and an appropriate antenna
system, hams can harness the power of ALE using one of the available
software ALE controllers.

How to Get Started in ALE 
The number of hams with ALE has grown steadily each year. In mid-2007,
when the ALE HF Network expanded to 24/7 operation, a big increase in
daily ALE activity was noticed. Some operators are following the
traditional ham curiosity to explore interesting aspects of
communications; others are developing dependable HF nets for Emcomm;
many are using it as a propagation tool; others are just using ALE for
fun, or to keep in touch with a circle of ham friends. Whatever the
reason, there's room for everyone.

About CAT PTT.
Support for most of ICom-transceivers is alredy built-in to RFSM-8000.
User can define ANY commands for CAT PTT.

Hi All...have been reading with some interest and some wondering about
this program ALEi know it is written for Windows but im wondering
if an attempt has been made to port it to Linuxyes there are a
large number of Hams worldwide who operate with Linux in one form or
another...ive been using Linux distros for about 6 years and i would
not go back to Windows...am i being left out of part of the digital
reveloution in Ham Radio because im not in the so called main stream...
