Hi Hans,
Yes I had a sneaky suspicion something might have changed in 2.03.
In the back of my mind seemed to suggest that in 2.02 it got
shifted, but I blew my 2.02 chip up with a little accident I had
(cough) so I couldn't confirm it ;-)
I've got a good stock of 2.03 chips now just in case I have any
more "senior moments".
Doesn't bother me either way, I'm entirely content here with
the versions I have, for me they are perfect.

Hi Andy, John
There was a request to keep the output on frequency and the TX going, in
FSK/CW mode in between frames, except during the 13 seconds calibration, so
that the temperature would be more constant and reduce the drift. This was
put into v2.03. An unintended consequence was that on WSPR, the kit stays
on frequency, though it is in key-up mode. However even in the key-up mode,
some signal leakage does occur and I believe this is responsible for the
effect you see.
In v2.04 I do plan to eliminate this effect: I'll move the DDS off
frequency or put it to zero frequency during key-up so that you don't see
this effect. As soon as I get a chance to do this, I will. But there are
only so many hours in the day, and they never seem really enough :-(
So in conclusion: just don't worry about it. It won't trouble WSPR decodes
and I'll take care of it in the next firmware version, for anybody who
still is worried about it.
