Hi Tony,
Thanks for taking the time to do that test for me.
I do hear the noise with an antenna connected, but the antenna is not tuned
for 5MHz so the noise floor is pretty low. I do

Yes, you can forward this info to whomever you want.

Hi Tony
I was able to reproduce the noise that James is hearing on my #1672 K3. In
my radio it never reaches S7, but I don't have the KBPF3 option. Here, the
RIT and XIT settings do not affect the noise. It is mostly between 4.9 and
5.1 MHz as stated by W4TV.
I never would have noticed this without

Hello Gregg,
If these are indeed pulses generated by the encoders, would replacing them
solve the issue, or is this a design

I had the encoder noise problem on 6M. It happened when I had upgraded the
software (don't remember the version). I reloaded the software and the
problem went away. It has been fine since.

... or why does it differ
from rig to rig??

Just checked. No added noise when tuning around 5MHZ.

Hi Tony,
Interesting... what settings did you have the K3 set too when you did the
test? Would it be possible for you to try

I was using SSB settings and had an antenna hooked up. I did not hear any
noise
I put a dummy load
OK gang, I don't know what to do at this point and you're my last line of
defense before sending this rig back to Elecraft engineering for analysis.
I'll sum it up briefly:
This is rig #2730. I bought it in kit form, and assembled it myself.
It has a sub receiver, 100w amp, KDVR3, KAT3

I've noticed that when I'm tuning around 4.8 MHz to 5.3 MHz,
I can hear EMI

James:
I suspect that what you are hearing is an artifact of the pulses generated
by the tuning encoder. These pulses are audible on some K3s

James,
My guess is that a design problem would affect all K3s. In your case,
it might
