Patrick,
It certainly seems difficult to precisely measure digital mode SNR so thank you
for explaining that. I think the PC sound card method is accurate enough to
show the relative difference between modes and more importantly, the digital
mode path simulations and SNR tests seem to correlat

Well done.

Suppose you think a desired station is on a frequency with his/her
FLARQ station active . You think that perhaps the station is set to
PSK250 and you know that conditions are way too poor for a PSK250
exchange . If that station has RS ID on receive activated (and we all
know we should always do
I have configured my digital mode interface and PC to use two
differing PTT ports and can run both FLARQ and WINMOR at the same time
see http://www.obriensweb.com/winmorflarq.jpg
Not literally transmit at the same time (that might blow up my radio)
but I can dual receive and I am thus available
So, a few weeks ago WINMOR was just a concept to most of use. Now many have
tested the simple soundcard alternative to $1000 modems and the verdict appears
to be... it works ! It works as an email/file sharing digital mode but not
perhaps as a strong competitor to Pactor III in terms of perfo

Hello Tony,
>What software are you using to determine the SNR decode level?
What i do is adding noise so as to reach a S/N=-15 dB. Then I see if it works
(decode or not). According to the result, I will try -14 or -16 dB etc...
In Multipsk when it is possible I evaluate the S/N by measuring the

Hi Doug,
I have
You will want to install it, what ever you add will otherwise be lost as soon
as you reboot.
In order to get the ham radio software you have to enable repositories to get
that stuff from.
Universe and multiverse should be enabled, medibuntu is extra. Look under
administration and start "software
I use Ubuntu 8.04 here with fldigi and qsstv and it is very well behaved. If
you are new to Linux, you could do worse than Ubuntu. I would consider going
with 9.04 though, instead of 9.10, at least until you figure out if all the
possible Ham radio applications you might want to run WILL run o
