Olli,
Referring to page 8 in the K3 Owner's Manual (may be a different page
for the K3s):
"Frequency Stability +/- 5 ppm for the TCXO standard; +/- 1ppm for
the optional TCXO."
TCXO-1 and TCXO-3 respectively mentioned above.
ppm means one part per million (1Hz per million Hz which is 1Hz
I have two of these, brand new in the box.
$140 each, shipped to lower 48.

Clay,
Use twisted pair wire between the switch and the RCA Plug. The tighter
the twist the better.
If you use that, there is no need for shielding.
If you do use a shield, connect it to the outside of the enclosure of

Obviously, the RCA is 2-conductor unbalanced and there is no issue about
which terminals to use on the foot switch for normally open switching.
BUT, I want to make sure the foot switch cable is never an issue for RFI

Must be D5. Removing the KXV3 and shorting pins 8 &10 and 13 & 15 on its
socket restores full sensitivity to the Main receiver. Thanks again, guys.

Excellent! Thanks to Dave, Joe and Don for the useful information. The
K3 is now on the bench and I'll start work soon. It most likely is D5 on
the KXV3.
Thank y'all for the quick response.

Randy,
I suggest you contact K3support -
There's a KXPA Utility configuration option to disable ANT 1 or ANT 2, per
band. Could you check that?

Bear with me because this is from my memory. To the best of my knowledge you
have to use the up button and down button to change values and cannot directly
enter the value. As I recall Wayne stated it would be added to a future
revision but apparently isn't present in the firmware you have

If you have the KXV3 installed, it is probably D5. I checked the
Mouser part number for the heavy-duty replacement, and it's still
good.

Is the main RX dead all the time (when using only Main RX - Sub RX
off)?
Two quick things to check ...
1) if the Main RX is dead all the time and you have KXV3/A/B boards
in each rig, swap them. If the problem moves with the KXV3, the
problem is most likely D5.
2) If the Main
Randy,
I suggest you contact K3support - they can likely give you a small
number of probable failure points. That will allow you to choose field
repair or send it to Watsonville.

Oliver, I was wondering about this, I guess it is just that the short term
