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. 73, Scott, N9AA On 10/6/12 7:49 AM, KD4NUE wrote: > 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.. > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
