SSB output with new firmware

[Ian Maude]

Hi all,
I installed the latest firmware this morning but have only just got
around to testing.  To be sure, I reset the radio and started the at the
beginning, calibration and all.  Having done all of that I set
the CONFIG:TXG VCE menu item to 3.0 dB.  The rig now almost gets to the
set power on voice peaks.  I would like a little more but it is close
enough and *way* better than the 50% I was getting previously.  A
really big thankyou to Wayne, Lyle and everybody else for such a fast
turnaround on a Sunday!!

Many thanks

Ian

Ian et al,

I did the same thing but found out later that my SSB audio sounded a little
"gravelly" as if I was overdriving early stages of the mic audio amplifier.
This was true even with no bars of ALC showing and with both my MH2 mic and
another backup microphone.

After a lot of tests and trials I finally discovered the problem disappeared
when I set CONFIG.TXG VCE back to 0 db which seemed to make little
difference in my ssb power output anyway.  So 0 db is where I shall leave
that setting.

Using a scope and my LP-100A meter set to oeak read, I find that I
need a setting of +2.0dB TXG VCE to equalise the SSB envelope with
a CW carrier. Before +3.0 dB was not enough.
