I have RFSM8000 installed on a machine here in Canada, although it is not
currently running. I have had some difficulty contacting Dmitri, and
wondered
if he is still actively pursuing RFSM8000. Have you heard from him ?
As a result we have been testing Pactor 3 for the same purpose.. it
Hi Wolf,
Be sure to keep us informed as to your results.
It is ironic that we can not use MIL-STD-188-110A type modulation here
in the U.S. HF ham bands, at least not in the text RTTY/Data areas, with
the requirement to keep the baud rate of any one tone no faster than 300
baud. The RFSM

Hi Alan
This is using the digi port on the 857 with all dsp functions off
but I need 2400 hz of audio passband just to fit the non standard
RFSM8000 signal in and just cant get it from stock standard 857
Maybe just put it back in my mobile

Les,
Are you sure it is the IF passband? If your BFO injection frequency is set
correctly, you should be able to pass 300 to maybe 2200 Hz. Otherwise, SSB
phone will have no lows.
If you have audio transformers in a homebrew interface, make sure they have the
necessary frequency response. The
Hello,
You should be using the digi port, and there is a specific setting that
allows you to center the filter passband around typical digi signals. I
find 200 hz up works best for ALE.
Since the signal is now centered, I can then even use the DSP bandpass
to really tighten up.
If you have

Normally, when I am operating digital modes, I start out with the full
3.6 kHz bandwidth and only tighten it up when I need to. The non
standard mode is likely a much better fit for some rigs. In fact, it
would seem that some rigs, even some newer ones, would not be able to
operate some of the

Using RFSM 2400, I was able to connect with the non standard mode, but

nothing would go through. There is a beep tone at the beginning of each
transmission and I see a large spike on the spectrum display which I

Hi John,
Can you tell us anything about how this technology is working out? From
what I can see from the web site, it replaces and is backward compatible
to RFSM2400.
Although we can not use it here in the U.S. on the frequency you
selected, it could be used to send images in the phone/image
John,
If this modulation is the MIL-STD/FED-STD/STANAG 8PSK waveforms,
wouldn't they be at 2400 baud at all times? We can not use baud rates
over 300 here in the U.S. on the text digital portions of the bands, but
they could possibly be used in the voice/image portions for sending
images/fax.

Les,
What do you see as the advantages of RFSM2400 over the 8PSK2400 baud
STANAG modems that we have been talking about recently (along with
RFMS2400)?
The only comment that I have heard so far is that it requires a good
signal to work. Athough hams can not use these modes here in the U.S. on
