- Hi ...
I've been looking for EVM apps for a while (a RTTY one). I found a 100 baud
/ 170Hz RTTY modem.
Is there any 170/200 Hz shift, 45baud modem available for EVM? I use RITTY
for Sound Card actually but would like to see EVM modem performance
comparing with K6STI routines. The idea is to use a different terminal
program with this modem ...
BTW, I'm available on MT63, FeldHell, SlowHell, PSK31, 15x25, from 10MHz to
30MHz to any tests. Has downloaded most of the EVM packages I found.
No, I don't know of any 45 baud RTTY applications for the EVM.
I think we need to have "reference" versions of several different
modems, so we can compare one with another using the same
platform and the best techniques. We would quickly learn which
is best under different circumstances.
Others I would like to try are Coquelet, Piccolo, SSTV, AMTOR
(particularly Mode B), Pactor, and MSK as used on LF.
Some months back Pawel SP9VRC volunteered to make an
EVM version of Coquelet for me, and I must get the specs
to him so he can get started. I understand that at one stage
Peter G3PLX tried Piccolo, but the details are hazy.
Are there any EVM programmer volunteers out there?

implementations, basically K6STI routine. I have the V2.37 (registered) and
I heard that he stopped at 3.04. It's a great modem: things that I can't
decode with Mix31 or a domestic 7910 modem pop up on Brian's routine.
Unfortunately he left the market and actually he's unreachable via e-mail.
So I was figuring if somebody wrote some good modem using EVM. I know, RTTY
is simple and EVM give room for more interesting apps but ... :o)

ok ... even windowed on W98. As I remember, I needed to do "something" to
put it running ... may be the routines are too big to PLX loader to handle
so loadevm.exe refused to upload (said more than XXX lines). So I uploaded
using Motorola software then switched cables and start the DOS application
... I guess ...
Well, from time to time I call usingMT63-1K on 14060/061 USB, mainly if I
can't hear AMTOR/FeldHell/CW there - between 21:00 and 04:00 UTC. But my
single QSO was with Fred (OH/DL4ZC), several months ago :o(
