On my p3 with the KAT500 tuned to 28.004434 the birdie is -95 dBm.
when I turn the KPA500 off it is still there at -110 dBm.
In my opinion that indicates the birdie is from the K3. When I turn
my 4 el Yagi-Uda to the south which puts the antenna 40 ft above and
30 ft North of the tower the
Mine generates a clean S4 carrier at 28.004.55. Does anyone else see this, or
know how to move it out of the band?

I have a signal there too. Switching off the KAT500 reduces it, but that is
due to the default antenna selection on power off. Changing antennas reduces
the signal level (the 2nd antenna is nearer to the house).
If I switch the K3 antenna source (no antenna connected to port 2) it is

Analysis: it isn't the KAT500. The signal is coming from another external

Not true in my case. The only way to completely suppress my spur is to remove
12VDC power to my KAT500 by disconnecting the power cable.
I agree with Bill, K1GC, the signal is internal to the KAT500. Switching the
KAT500 to bypass reduces it, but only disconnecting the 12 VDC line to the
KAT500 gets rid of it completely. NOT an external signal. Seems to be coming
into the K3 via common mode.

Anyone try a ferrite or two clamped to the jumper between the radio
and tuner (or between the amp and tuner)?

I’m using Elecraft cables for both connections; those cables have beads on each
end. I added two more beads to each cable while watching the spur level with
the K3 dBV meter; no effect.
FWIW, I’ve heard from two others KAT500 owners that hear the spur but didn’t
post to the reflector. The spur
Ok, my bad for being incomplete in testing. I've now pulled the power off
of the KAT500 and yes the signal went away completely so it is the KAT500 as
the source not one of the other numerous sources around the shack. It is
reduced with power off, gone when the power is gone; antenna selection
For me it is there but doesn't move the S-meter. I can barely see it on the
P3 or SDR-IQ/SV.

I call my shack the aviary so a new birdy didn't shock me. This one did come
along with the KAT500. Unplug it and it goes away. P3 screen scrape here:
