I ran the SSB frequency response yesterday on v. 2.033 and found it to be
identical to the previous tests with the settings at BW=3900, LF Cut-off=50,
EQ=0. The EQ level calibration appeared to be more accurate, IOW setting it
at +6db gave it 6 dB of boost at 100 Hz vs. around 3 dB in the previous
version.
I also tested to see if the low frequency response changed if the TX BW was
changed, and I could not see any difference.
I have noticed that the AM works different in that the power output is now
about 50 Watts, and does not change as the PWR control is reduced from 100%
to 50%. Below that, the ALC light comes on and the audio starts getting
distorted with serious downward carrier shift. There is also some carrier
shift on peaks at 100%. If you run AM at 100%, it's probably fine, but
since I generally run through an amplifier and only need about 10-12 Watts
carrier, this could be a problem.

The transmit audio sounds good as I hear it in another receiver and the on
air reports are good. Hopefully, N6AHA or another technical and test
equipment equipped user will post the results of the audio, then we can
"see" the results.
