Brian,
I have that occasionally, and reseating the 3.5 mm connectors on the SDR
cures it.

I have recently been receiving reports of a slight echo on my tx
signal. I can reduce the problem by turning off the leveler and winding
back the microphone audio gain. The problem with winding back the audio
gain is of course that it reduces my power output. Echo comes into play
at the -25 Db level with the Tx meter set on Mic. I have reduced the
audio buffers to 256 which makes a slight improvement but I cannot get
rid of the echo completely. The echo is audible when I listen to my
signal in a separate receiver.
Anybody have any ideas on where to next? Running PowerSDR 1.6 SDR-1000
100w, D44 card and Heil goldline microphone. 2.3 Ghz P4 PC.
Thanks
