A switch from VFO A to VFO B is unrelated to any pot sitting at a switchpoint. You should be looking for some other cause of this 'flakiness' - something is causing the microprocessor to execute a routine that it should not - it could be coming from a glitch on the pushbutton matrix, a bad solder joint at the switch that is just now showing up, or even RF getting into the K2 - these are just a few things immeditaely off the top of my head.
You might try loosening the microprocessor a bit and reseating it. It is possible for slight corrosion to develop at the socket to IC pin pressure connection, and the wiping action created by re-seating the socketed chips can often make the problem disappear - it certainly will not hurt anything to re-seat the uP. 73, Don W3FPR > -----Original Message----- > > I now have the rig jumping from VFO A to VFO B, in addition to phantom > displays of power level (the latter more likely to happen shortly after > stopping spinning the VFO). > > These do _not_ necessarily happen during transmit, or during transition > from transmit to receive or vice versa, so unlikely to be RFI. > > The VFO A to VFO B switch happened twice this morning - both > times during period of receive & with no operator interaction > with the rig. > > 73, VR2BrettGraham > _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
