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

I think you are right about the burst characteristics of the mode and the way
the PathSim software handles this. Seems logical since our SNR tests have been
consistent

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
Patrick,
Just checked the peak amplitude of the RSID / Call ID clips and they are both
within 0.2db of each other. These are the audio files I used to determine the
100% throughput SNR for each mode using PathSim. I am sending you the files so
you can test them at your leisure. The RSID (Mode

The Call ID S/N is not precise at all. It can only give an idea of the S/N
value.

I have an audio editor that has the capability of adding white noise, but it

Patrick,
Thanks for adding the messaging feature. Andy, K3UK, and I were able to copy
Sholto's, RS messages some 3700km away on 20 meters. Sholto, K7TMG, was running
5 watts and a vertical antenna. We found the high sensitivity

Steinar,
I am testing the Message ID in Patrick's latest beta of the
MULTIPSK (VERSION 4.16 of 27/10/2009) on 14.074.
I haven't had the opportunity to use the message ID on-the-air, but I did test
the mode between two PC's and it seems to work fine.
I would assume the Reed Solomon
