Hi Andrei, This is Bernard F6BVP in Paris a long time Packet radio and satellite user. Presently I am involved into radio telescope F4KLO rehabilitation. Together than monitoring Galaxy hydrogen signal we also listen to SARSAT satellites transponders that transmit emergency messages from distress beacons on L band. The beacon we monitor and would like to decode is using BPSK 2400 bauds bauds on 1544,5 MHz from SARP module. I tried using your three soundmodem versions. hs_soudmodem looks the more likely to decode BPSK 2400 bauds. I don't remember the specificity of James Miller G3RUH modem specificity and I wonder if your implementation could be used to decode BPSK data stream at 2400 bauds. Additionaly I did not find 400 bauds BPSK on your software. It could be useful in order to decode geostationnary amateur QO-100 satellite 400 bauds PSK beacon AO40 compatible. However AO40Rcv.exe can be used for this one. 73 de Bernard, f6bvp https://radiotelescopelavillette.wordpress.com/

Hi there, Great software by the way, really useful! Just moved over to V1.5 this week and having problems with the program waterfall stopping every few hours. Do you have any idea what might be causing this, or have a link back to the old V1.05 or last version please? Regards, Dave.

Andrei, AQuick note to thankyou for the Elecraft CAT support in Soundmodem 1.05 I just configured it for my KX3 to support CAT control for WinLink Packet ops on VHF. Flawless in all respects. Yay ! 73 Bob k7au Lacey, Wa Sysop K7IF

Greetings Andrei: I have been using Soundmodem (ver 1.05) with Winlink Express on windows computers for some time. I'm attempting to get it to work on Ubuntu running it using the Crossover app. Both Winlink Express and Soundmodem are running fine. Soundmodem seems to be receiving as when I turn the squelch off I see the result in the waterfall. However, when I try to connect the Signalink PTT is not actuated and the radio is not keyed up. The Ubuntu sound setting have the same device (PCM2906C Audio CODEC)specified for input and output. Volumes are set at 100%. I've tried varying the SignaLink TX level but it makes no difference. Any suggestions would be appreciated. P.S. My grandfather (father's father) emigrated from Ukraine in 1905. Don't know exactly where from, but supposedly somewhere near Kiyv.
