Evert, Yes, I believe using the AUX RF BNC is the preferred solution for your case. If the main receiver will be on a lower frequency than the sub, the low pass filters will be set for the main RX/TX and would severely attenuate the higher frequency input to the Sub RX.
It may make your external antenna connections or switching scheme a bit more complex, but it is one of the compromises that one must make when tuning different bands with one transceiver. 73, Don W3FPR Evert Bakker (PA2KW) wrote: > I'm installing my KRX3 now and trying to figure out which configuration to > install. > > After reading the KRX3 manual and the K3 manual and looking at the pictures > on page 40 (K3 manual), > > > > I do have KAT3 and KXV3 installed. > > I do have a separate RX antenna for the low bands. > > I want to use the SUB-RX on the higher bands together with the main RX with > the same antenna and accept an increase of the NF by 3 dB. > > > > Do I need the AUX RF BNC installed? > > > > 73's, Evert PA2KW > > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
