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. 73 de Dick, K6KR -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of KD4NUE Sent: Saturday, October 06, 2012 4:50 AM To: [email protected] Subject: [Elecraft] KBPF3 Option - Main and Sub Receiver 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.. -- View this message in context: http://elecraft.365791.n2.nabble.com/KBPF3-Option-Main-and-Sub-Receiver-tp75 63771.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ 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 ______________________________________________________________ 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
