Yes, can't work out where the frequency shift came from.  I did
initially lock onto Jim's tramsission at the begining of each of his
overs, so I would indeed have jumped in freq a couple of times.
Subsequently 'Locked' the Tx frequency and Jim reported no more freq
changes from me after that, although he did end up a few Hz lower
still.

I was using Digipan software which is a bit too QSO-orientated and too
easy to shift frequency to follow others.  So it is quite possible to
end up chasing eachother up and down the band!
Perhaps it would have been better to use G3PLX's  'PSK31SBW' software
which puts precise frequency setting first and QSO mode gimmicks
second.

Anyway, I estimate somewhere between -7 to -4dBW, and will only know
better after some antenna base current measurements, rather than doing
it an the end of 20m of feeder in the shack.
