I listened last night, and that was my thought too.  The FM downlink from 
Echo was twenty over nine, with a lot of white noise in the background much 
like you hear when listening to a 9600 bps signal, but the audio level of 
the stations making contacts on it was low.  Receiving Echo shouldn't be a 
problem if the output is lowered, at least for me anyway, but I wonder if 
it's possible to increase the receiver gain on Echo so SSB signals come out 
louder.  To me it seemed the audio should have been louder as I was 
receiving the downlink almost full scale.
