[TenTec] PSK31 with the Peg

[Mark Erbaugh]

Jeff,

Are you having a problem with the TX audio or the RX audio? The audio input
to the Pegasus, even on the ACCY input is actually at mic levels (5 mV). You
need some heavy attenuation. I'm currently using a 10k pot across the
output, with the Pegasus begin fed across the slider and ground.
