It's possible, because the panadapter can show a much wider bandwidth than the K3's crystal filter allows into its own I.F. But such signals would have to be above the panadapter's noise floor (at the buffered I.F. output). Most birdies are inaudible with an antenna connected anyway, and some might be finding their way into the second rather than the first mixer, so it's hard to predict which ones would make tiny blips on the panadapter. If this turns out to be an issue, I may be able to enhance the K3's "FI" command, which the LP-Pan uses to get the current I.F., to flag the occurrence of a mapped-out 100-Hz VFO segment. 73, Wayne N6KR --- http://www.elecraft.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
