After some investigation, this appears to be because of the way
the MP reports its frequency. Most radios always report their
transmitted frequency - even on CW, where there is an offset
(in this case - 900 Hertz).
However, I guess the MP (in its standard configuration) reports the
actual receiver frequency. So, if you set a frequency in CW, and
then change modes to SSB, the radio's reported frequency will shift
by 900 Hertz. The same thing happens in reverse when going from
SSB to CW!
Curently TR has to send two commands to the MP to change frequency
and mode. It does the frequency first, then the mode. I believe
I can solve this problem with the MP by simply reversing the
two and changing mode first. This will be in the next release.
Subtle differences in new radios compared to their previous brothers
is going to drive me to the funny farm!!!!! I think I need a contest.
See you in the SS SSB as K7RAT, Q power.
