Hello Mike,
I did not recognize any instability during my QSO with Cesare. But It was
the first time I heard him and maybe the problem was cured in the meantime

To Alan,

Cesare appears to have a rather interesting oscillator - a bit like the
one I used to use. So his transmission drifts and wobbles by a few
Hz. This has the advantage that it is easily recognised, but the
disadvantage that the averaging on the DSP is not fully realised.

To Cesare,

It would help your signal if you could make it more stable.
Successful oscillators include divided down crystals, synthesisers
and mixed VXOs. There are some oscillator circuits referenced from
my Links web page.

I can't claim any success for my stability improvements - they are all
down the generosity of David, G0MRF, who built the synthesiser I
use, but it does make a difference.
