KBPF3 Option - Main and Sub Receiver

[KD4NUE]

I am a new owner, and have much still to learn on this rig.

Do you have to install 2 of the KBPF3 Option boards in order to have both primary and second reciever have General Coverage Receive filtering?

Mine appears to be installed in the second receiver, and throws an error if config is set to show it installed in the RF (Primary).

I think the answer will be yes if you are to be able to monitor 2 separate bands simultaneously, but would like to know for sure..

Yes, if you want to use both main and sub receivers on frequencies outside
the amateur bands, you'll want two KBPF3 options.

However I find I need just one general-coverage receiver. I have my single
KBPF3 option on the main receiver.  I use the second receiver for diversity
and split frequency operations only on the amateur bands.  

I don't think I'd use a sub receiver KBPF3 very often.

Your needs may well be different than mine. If you want diversity receive
outside the ham bands, you'll want both.

Welcome aboard!!

You only need the KBPF3 if you want to listen to frequencies outside the
amateur bands. My recommendation would be to remove the KBPF3 from the
KRX3 and move it to the main receiver, but if you want general coverage
RX in both receivers, then you'd need to install one on both receivers.

The KBPF3 has nothing to do with the K3's ability to listen to two
separate bands simultaneously, only with general coverage RX, so with
the K3 with the KRX3 installed, you can monitor six meters on one
receiver and 160 on the other, if you'd like.
