Terry,
I don't know if this is the same problem, but there is a well-documented issue with MicroKeyers (actually with the Winkey chip). It has to do with the properties of certain metallic compounds used in the contacts on the keys. The Begali keys are the ones most apt to have the problem, but there could be others. You end up with extra 'dits' and occasionally other anomalies. The fix is somewhere on the microHam USA web site -- they sell an interface that goes between the key and the MicroKeyer and fixes the issue, Good luck and 73, John, WA6L g4amt wrote: > > Has anyone had a problem with RF getting into the paddle input of the MKII > ? > Problem is reduced somewhat by careful adjustment of the router `Winkey` > page, but essentially series of Ds likey to turn into Ms and Gs (!); fine > with K3 on test so has to be RF based.
