[Elecraft] Weird EMI issue... part deux

[James Sarte]

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 without any antenna connected,
and have the K3 set to AM?  For me, it seems to be loudest on AM mode and
also when the preamp is turned off.  In the absence of any signal entering
the receiver is when this noise is loudest.

I've also tried reloading the software several times, from 2.78 to 2.82 and
now 2.96 and haven't noticed any difference.

If it is encoder pulses or something the synthesizer is doing around 5 MHz,
then why can't other people recreate my problem... or why does it differ
from rig to rig??

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

Hi James,
Just checked. I am using 2.82. Guess I got behind on the upgrades.
The only thing I do around 5MHZ is 60M and these channels are in memory. So
I would not be tuning around 5MHZ to check for this problem. Will try tuning
around 5 later today and will let you know if I have this problem.

I assume you tried reloading the firmware.
