[App_rpt-users] Using DSP on Rasberry Pi?

[John Griffith]

I see what you're getting at.. the RF from the transmitter may be interfering with the CPU in the receiving radio, locking up the COS. I'll do an experiment and let you know. May be a couple of days, but I'm going to start on the Pi project tonight.

Hi John,

Out of curiosity, if you disable the transmit radio, how does COS behave on the TYT?
