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.
