>> Here are a list of problems I found right off with the v. 2.042A, even
>> after doing a battery reset and two master resets and memory clear:
>> 1.. Very noticeable distortion on all audio. Sounds like overdrive in

>> 2.. AGC hang in AF AGC. S-meter goes up and never comes down! At same

>> essentially muted. This will not happen if the "AGC Hang" setting is 0,
>> but then distortion is really bad.
>> 3.. NR does not work in AF AGC mode. Does seem to work well in RF AGC
>> mode.
>> 4.. Much more audio drive needed on AUX input for SSB. It looks like
>> about 10 dB more.
>> 5.. AM carrier= 1.25 Watts max! That's at 100% PWR setting.
>> 6.. FM carrier= 6.4 Watts max.
>> 7.. SSB Speech Processor gives only around 50 Watts max peak output.
>> You
>> can get it up to 100 Watts when you crank it to "way beyond reasonable
>> distortion".
>> 8.. Could not find any sort of S-Meter calibration
>> Here are the good points so far:
>> 1.. Side tone is louder and spot level is too.
>> 2.. Waterfall display is much improved.
>> 3.. Difference in frequency between Main and Sub improved, but still not
>> "phase locked". I detect about 0.1 Hz differential which should make it
>> fine for true diversity antenna work.
>> 4.. In RF AGC mode, the NR really does seem improved, although it's hard
>> to tell with the audio distortion mentioned above.
>> So that's the good, the bad and the ugly of it! I'm QSYing back to v.
>> 2.039d, the last one that worked right...
