Re: PSK-31 transponder

  The whole idea is to monitor the conversations, not participate in all of
them! You just join one, usually someone calling CQ. The software is called
PSK31 Deluxe. It can monitor up to 40 different QSO's. Also the program
WinPSK31 monitors 2 QSO's, and works in full duplex, or can be used on a
satellite. A group of us used to run psk31 50k below the beacon. It was fun
adjusting for the Doppler when there were 3 or 4 conversations going on at
the same time in less then 1k bandwidth. The yourcall color coding is a good
idea, kinda like WiSP does.
