K2 ATU

[Ellam, Timothy St. J.]

I have a problem which I am sure is my own error, but for the life of me I cannot seem to find the fix. I just switched the K2/100 module with regular K2 cover which has the K2ATU. The menu shows ATU as "auto", but neither Ant jacks 1 or 2 seem to function, The regular BNC that is not connected to the ATU works fine. I thought once the ATU was installed that jack was disabled?  Am I missing a menu change or do I have a more substantive problem?

There is a RF cable from the ATU to the mainboard. The auxbux is detecting
the ATU so that's connected, but the RF most likely is not. The RF cable
plugs into the main board at RF-P6. Do not connect it to RF-P3, the battery
connector!

Tim,

Even when the KAT2 is attached, you can still hear signals through the
base K2 antenna jack - that is NOT a problem.

If you cannot receive through the ANT1 or ANT2 jacks on the KAT2, the
problem must be with the KAT2.  Since I presume it worked before, look
for the easy things first, like a break in the input coax or improper
seating of the crimp pins in the connector.

If you set the menu to ATU CALP, you should be able to make a continuity
check from the input coax center conductor to the center conductor of
ANT1 or ANT2.
