[TenTec] microphones and ten tec gear

If the culprit is an improper setting of carrier set point (aka "carrier 
offset"), then you should notice your RECEIVED audio as sounding "bassy" as 
well.  If so, it is almost definitely this adjustment - if not, it's 
probably not.

A soundcard-equipped PC can easily plot the audio response by feeding the 
receive audio into the soundcard's input and running SR5 
software(www.ar5.com to download).  Tune to an open frequency (noise) and 
run a plot.  You should definitely see an audio response that is fairly flat 
out beyond 2000hz with the 2.4 filter.  A plot of my Corsair is at 
http://www.albany.net/~bg/Audio/Corsairspectra.htm although this is slightly 
more extended due to the Inrad 2.8 filter
