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.
