I suspect it is also caused by noise on the speed/power pots. The volume pot track is well known to become noisy over time, but the same applies to all four pots. My CW speed pot (K2 2498) is now quite touchy with only a very small change causing a significant change in speed, and the RF gain pot (normally left at the clockwise endstop) is also showing signs of noisiness. Any noise on the speed and power pots will be interpreted by the DACs and cause the transient display change we are all seeing. As others have said, just ignore it. It didn't stop my activity in CQWW with 851 QSOs in the QRP section.. I guess the answer is better quality pots... 73 Dave G3YMC http://www.davesergeant.com _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
