Patrick,
It certainly seems difficult to precisely measure digital mode SNR so thank
you for explaining that. I think the PC sound card

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 I

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 sensitivit

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.
