Well, MIL-STD-188-110A uses a single phase shifted
tone , I guess that made it even more non-intuitive ?
The difference between packet and this MIL-STD is just
huge. Interleaver to fight fade and QRM, equalization
to benefit from multipath and the list could just go
on and on. 300 baud packet is a

Hi John,
I haven't used it, but it looks like a good program for managing ALE
networks. It certainly could be useful in generating all the different

Hi Jaun,
I recommend you try transmitting an HFL Netcall.
That works better than listening.
It will trigger all ALE ham
After getting a PIII laptop into the shack (which, like my PII still,
unfortunately, runs on Windows Me) I was able to get DigiTRX to work

Since there is work presently being done to advance HF data
communications, I thought it would be good to start a dialogue
here about the advantages of PSK signals on HF, over some of
the other choices. I'm not a world expert on these particular
systems, however, I have used them and have an

If the 110A works this well at 2400 baud, what would happen with slower
speeds? From what I understand, it does require a good signal to get
through, perhaps comparable to the WinDRM software at maybe +10 S/N dB
or maybe a bit below that?

Poor Bonnie!
We are hitting you from both directions:
--some want better weak signal performance at the cost of speed (~HF)
--some want more speed at the cost of signal performance (~10M VHF)

The slower speeds are better when the condx is worse,
75 bps and long interleave gets through just about
anything. I have not really had to use it at that
speed , 1200 bps gets through nicely too. I don't know
how good the implementation in RFSM is, my experience
is based upon years of daily use
What if an individual wants high speed AND good low signal leveel
throughput?
I think the first thing is that individuals need to decide what USER
throughput they want in CPS or WPM or PPM and then at what the lowerest
SNR they expect the mode to provide 95% copy (or some percent of
perfect).

Hi John,
Fortunately, this choice is already built into the 188-110 system.
Here is the specification a 8PSK MIL-STD-188-110 modem meets
I was able to find some interesting data on poor channel performance of
the 110A modem from one company:
http://www.etools.de/software/telekommunikation/komponenten/milstd188110a.htm
Depending upon the BER you can tolerate, it appears that the 2400 bps
speed can only handle around +10 to +14
Bonnie,
Your definition below is not at all my understanding, nor does it square
with anything that I have read on baud rate.
My understanding for many years has been that baud refers to the symbol
rate per second. In other words, the actual changes or transitions
taking place per second.
Yes.

Hi Bonnie,
To condense, is your opinion as follows?
It is legal, in the US, for image or voice content on HF in the
image/voice subbands.
It is not legal at all, in the US, in the RTTY/data
Hi Howard,
It is best to arrange a sked on Digitalradio or HFLINK group.
We have previously used one of the ALE channels at 14346.0kHz USB for
sending images with the 188-110 modem. We link first on ALE, then use
SSB Voice QSO for setting things up. We don't use any texting or chat
via keyboard.

I would rather have ONE mode that is scalable so that you could
merely adjust it according to the demand, speed vs SNR, etc.
Please write to me off-line if you plan to attend HAMCOM in Dallas.

I cannot seem to get this software running properly.
I can call another station, and his station answers me , looking for the

But I don't see ANY packets from him and can't carry thru with the connection.
His signal looks good,
everything seems to be working the way it
Hi John,
I had a similar experience running RFSM2400 under Wine on Linux.
I set up a clean Windows system and went to the latest version of the
RFSM2400 package and that cleared it up.
The best I could tell, my software was seeing the other station because
the S/N and speed were appearing in
Hi Bonnie,
Thanks for initiating this discussion:
Throw the prospect of incremental frequency shift keying into the mix
for discussion; know a few are working on this mode(s)also.
The OFDM (AM-QPSK)+6dB better SNR may or may not be an issue...it
depends on usagethe usual HF near LUF

The 'legal mode' issue keeps coming up everytime a
new mode is introduced. Life is too short to try
and make sense of Part 97 so I think it would be
useful to have a list of guidelines to help
determine whether a mode meets FCC rules or not.
It should be to the point and concise;
