My K2 just started doing the same thing. I redid all the solder joints between the board and the encoder, then checked the list archives to see if anyone else had that problem. I am going to order and install a new encoder. The reason I think that it is the encoder itself is that with

Just started the the alignment test Part 1 on my K2 (Rev. f) page 42. Everything went well, no smoke or error codes, until I got to the Optical Encoder Test step2. It says to turn VFO knob in both directions and verify that displayed freq. changes accordingly. The only change I see is the

Sounds like you are missing one channel of the encoder -- first step is to check the soldering. Looks like the two encoder channels ENC A and ENC B go to the RF board via pins and 13 of J1. Check the soldering on those pins on the RF board and the front panel board, also pins 9 and 16 the MCU
