..... Ideally these
transmissions should be in the 'test' area of the agreed band plan below
136.0.

Tut tut Walter, you are in trouble with the 136kHz police

The wobbly osc should be cured soon (why does an osc wobble when
it's got three buffers between it and the load?)
I used a signal generator with lots of buffering in the early days of
136kHz. Although to was fine for CW it produced worm shaped traces on QRSS.
I think it was caused by RF feedback. I am not using my crystal mixer
exciter (which has been replaced with a DDS unit) which you are welcome to.
This is fine for normal QRSS but has a +/- 2Hz long term drift, which made
it unsuitable for transatlantic stuff
