[Elecraft] Encoder Noise
Hi All, On my KX3, I seem to be getting a very loud noise anytime I move the encoder on 6 meters. I don't notice that at all on any other bands. Any thoughts?

[Elecraft] Encoder noise on K2
I just noticed that my encoder is making noise on the 15 and 40 meter bands. On 15 it is from 21.000MHz to about 21.015MHz. On 40 it is on and off through the entire band. I haven't noticed this before when turning the tuning knob. Of course, it only does it when I'm turning the knob. It doesn't make any noise on the other bands. I have made some changes to my K2 in the past week. I installed the 160m module, took off the KPA100 and reinstalled the original top with the KAT2. The first thing that I will check is to make sure that the cable for the KAT2 is routed properly and didn't move when I reinstalled the top. My K2 is #6113.

Re: [Elecraft] Encoder noise on K2
Gary, If it is more like a pop every 5 kHz., you should run CAL PLL to cure it. Before doing that open the bottom cover and check RFC15 with your ohmmeter (that is the small RF Choke soldered to pin 16 of U4) Check it with your ohmmeter - it will read 5 volts on each end even if it is open. 73, Don W3FPR On 7/19/2011 10:19 AM, Gary D Krause wrote: I just noticed that my encoder is making noise on the 15 and 40 meter bands.
