K3-KRX3 Clarification

[Terry Schieler]

I am completing the installation of my KRX3.  I am electing to share the selected antenna (ANT-1 or ANT-2) with the sub receiver.  I have the KAT3 installed.  Do I still need to connect the 12” TMP cable between the KRX3 and J92 on the KAT3, or is this connection made somewhere else in the circuitry?

 

On page 37 of my KRX3 installation manual (Rev. A) it states “If installed, attach the antenna cable connected to either the KAT3 or to the AUX RF BNC jack on the rear panel to J92 at the end of the KRX3 as shown”.  I DO have the KAT3 installed, but am confused if this cable is REQUIRED for the sub receiver to work at all, or if this step is referencing the option to “Installing the Auxiliary KRX3 Antenna Input Via the KAT3” which I have elected to pass on.

 

I don’t see any other way of the signal getting from the ANT connection on the back of the rig to the sub receiver, but, then again, there are a number of multi-pin connections on the sub receiver.

 

Please respond direct as I am in digest mode and would like to wrap this up this afternoon if possible.  My call AT swbell DOT net.

 

Many thanks.

Terry,
 You only need to connect a TMP cable to J92 on the KRX3 if you want to use an auxiliary input for the KRX3 ( either via the BNC connector that comes with the KRX3 or via the KAT3 antenna terminal that is not being used for the main RX and TX, you can use only one of these options ). If you don't want to use an auxiliary antenna at all you don't have to connect anything to J92 on the KRX3. See pages 24 thru 29 of the KRX3 installation/operation Manual Revision C.

You might want to wire up AUX RF BNC/TMP assembly even though you have no immediate plans to use it.  You can route the TMP cable and tape it safely out of the way.  This will save a LOT of work later if you ever decide you need it.
