David, thanks. I think I have sorted it all, at least on CW! I have
just re-aligned with the Spectrograph. The MP has on offset in the
display I recall, so displayed is actual frequency, (I think!)
Now, simulating a QSO, ie transmitting on K2 and tuning in on MP, then
txing on MP and listening on K2, I hear each signal without retuning,
and as it happens both indicate the same freq. I am now convinced that I
was transmitting 1 KHz lower before, which explains why I was calling
VQ9JC on his tx freq even though I had XIT in, and wasn't being heard by
NO2R who was listening co-channel.
Apologies to everyone for the numerous emails, thanks for all the
advice. A learning curve!

Do not be misled by the fact that on CW the K2 transmits on the
frequency as displayed, whereas many of the oriental black boxes
transmit a fixed number of Hz (maybe 600Hz) different to the displayed
frequency to give the required offset.
I have encountered a similar problem with working black boxes on
144MHz with my K2/KXV144 combination.
I find that the best way is to call on the K2 and then tune the black
box for a suitable beat note. You'll find that the two displays will
differ by about 600Hz.

OK, I think I have sussed the problem. Now I need the solution, which
I suspect is re-alignment.
- K2 tuned to 3500, FT1000MP tuned to 3500.
- Transmit on K2 and hear signal on FT1kMP, within 40Hz.
- Transmit on MP
- Nothing heard on K2
- Tune around and signal audible on 3498.90 --- 1100Hz low
Suspect I have the BFO on the wrong side. Back to the drawing board!
