I’m testing a URI on a server with a scope connected

When I send audio to the URI (CLI> radio tune txvoice 500), PTT activates the red LED (scope confirms), and the scope responds to the LEFT_AC start and stop (ramped dc offset), but no tone. I’ve checked both channels.

I’m wondering if I have something set incorrectly. What am I missing?

Here are my tx settings.

hdwtype=0    

txboost=1

txctcssfreqs=107.2

txprelim=no

txlimonly=no

txtoctype=notone

txmixa=composite

txmixb=composite

duplex=1

eeprom=0

Thanks,

Bob
