My K3 also exhibits what I assume is "encoder noise" - ie noise which
persists only whilst tuning and stops as soon as I stop tuning. The effect
is audible near the bottom end of 28MHz (annoying for those of using
transverters!) and also on 50MHz (whether ant connected or not).
 
If I use the RIT control to step thru' the band in 1kHz increments, the
noise is not audible.
 
 Any advice?
