[TenTec] [Orion] O2 Tx audio quality

[Ron Castro]

You are most likely right about that.  The DSP code can change the frequency 
response of the system, and my measurements show the low frequency response 
is off quite a bit from the published specs.  I compensate by turning up the 
50 Hz EQ on the W2IHY 8-Band, and that seems to fix the problem, although 
it's not truly flat audio response.

That's one of the things I have on my "List of things for Ten Tec to fix" on 
my website!
