Hi Victor,

Thanks for the feedback. Yes i see i'm drifting. Not so fine. There were some missing decodes. Must have been due to the timing or maybe the drift?

My TX converter is quite an ugly construction. It was grown from a very temporary arrangement of a few electronic parts. The drift may come from some nearby parts (The ICL7667 and a 78S05) which become warm during TXing and feed the heat to the xtal. I will investigate...

73, Stefan
