Hi,

Does anyone know of US frequencies where the MIL-STD-188-110B 39-Tone
Parallel Modem can be regularly heard?

Thanks,
John

A good source for current utility frequencies is the World Utility News
websitr. I subscribe (snd occasionally contribute) to their newsletter
that is free and you can have email to you daily. It's more then hust
Mil-A;e and is very informative covering all HF modes. They also link
to a Number and Oddities newsletter if that interests you. The
contributors are knowledgeable, many from the U.S.

The Worldwide Utilities website is really interesting and loaded with
information - thanks for posting it. There is enough there to get me
interested in that part of the hobby again.

Just for some additional info. a god MilAle decoder
that is free is PCAle . If you Google PCAle you'll get the link. Again
it is freeware not Shareware

Thanks. I'll show how long it has been with the following question.
Are separate decoding modems used any more or is most digital ute work
done via the pc.

I dropped out when my PK232MBX couldn't be used for much decoding.

There are pc cards that decode but I use PC Software that only requires
a regular cable from the receiver to the mic input on your pc. There
are alot of programs available on line. Some freeware others shareware.
Again if you Google Soundcaed decoding software there at lease 2 sited
out there that list them with descriptions and links to downloads.

PCAle
PCHFDL
and iNavtes
are free

JVComm43 is a great shareware program for
HFFAX, RTTY, Navtes, SSTV, Amtor

A Few Years ago I purchased Skysweep Standard that does abot 25
different modes and had a built in DSP module and Audio Recorder.

The receiver that you use should be selective and able to tune to 1 khz
for best results and use USB unless noted by the list you refer to

Good Luck and enjoy,
Charlie

Thanks Charlie. I'll use the Kenwood R-5000 which should have
sufficient tuning resolution and selectivity. Does Skysweep include
auto sensing capability.

I've heard digital signals (though not sure it is the standard you
mentioned) on 5703kHz. I used USB. From the FLIP, 15091kHz should have
similar traffic. The frequencies are listed as Raymond 27 (Mountain
Home), though I've heard them in use in the Nellis ranges.

They are listed in the FLIP document ap1b.pdf
