Something is acting as an antenna. I made several hundred mile
contacts with a 100w light bulb "dummy load" on 40m in the 1950's.
Might be ground system is working as antenna or radio as found
connection via other equipment.
Be interesting to find out what you discover.

KAT500 antenna port isolation is not impressive, at least not after using an
Alpha Delta 4 port switch. I have ANT-3 port connected to an Alpha Delta
switch that selects either my dummy load or a back yard antenna. The other
KAT500 ports are connected to a 40 m dipole and my SteppIR.

Great story!
I worked a station in the USA last night on 40m with 5w. I had just
adjusted my antenna tuner (yes, I know, but it is impossible to find a
totally clear spot during CQWW), and I forgot to restore normal power
and turn on my amp. I wonder if he noticed the difference when I came
Smart mouthed answers are not required, least of all here in this group. You
know better Bill.
He has at least one coax running from the radio to the KAT500, plus there may
be other coax and/or switches attached in that path.
All should be checked. No magic involved in that.
If he
I have worked DX on a cantenna and a TR-4. It was setting on the workbench
in the back of the room when we were doing a multi-single in the 10 meter
contest many years ago. The radio was turned on as someone had been messing
around with it. I walked past and heard an HK call from the speaker. The
If the KAT500 is not bonded to the K3, external to the coax, and the
combination is not bonded to the building's earth electrode, you DO have
an antenna on the K3 and are demonstrating that its MDS is impressive.
It doesn't take much to make a receiving antenna. Actually, if you saw

John,
It sounds to me like you actually do have some kind of antenna effects
floating around in your shack.
Pickup from RF on the outside of the coax being conducted to the ground
plane of the receiver through some "sneak paths".
What happens if you disconnect the receiver from the KAT500?
Duh? With no coax connected to it, what connectors should he check?
He’s getting distant stations with no antenna, no stations with antennas
connected.
It’s magic!

Check ALL your coax connections (and quality of coax), making SURE that
the connectors are properly attached (soldered or crimped) to the wires
AND that they are securely attached to the mated connector on the KAT500.
A /little/ leakage is normal but unless that station is 40 over 9, you
Sounds like you have a great receiver

I have a KAT-500 at least 4 years old. I can hear stations without any
antennas connected to it. I live in Clarksville, TN and I copied station
in Bradenton, FL 600+ miles away on 14.3 MHZ. I have had the same thing
happen on 40 meters as well. Any ideas???
