When using diversity receive, both receivers should use the same filter. You enter diversity receive by pressing SUB for a looong time. Manual says 2s, that's probably right, but it feels longer. The two receivers have to be connected to different antennas. The details are in the manual. But *why* isn't the sub-receiver antenna input grounded when the K3 is transmitting? On most bands, if I try diversity, the relay protecting the sub input starts clicking, and that means I should turn it off. 73 Jon LA4RT > Be interested in any opinions.....73, > > Stewart, GW0ETF > > -- > View this message in context: > http://elecraft.365791.n2.nabble.com/K3-Choice-of-filters-in-KRX3-tp6932305p6932305.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:Elecraft@mailman.qth.net > > 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:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
