While the narrowest XFIL is very good, I need sometimes to use the APF to listen to small signals. There is a discrepancy between their center frequencies. It could be considered as small, but it becomes annoying with XFIL on BW 0.05 : sometimes I have to shift the APF freq. to get the best decodable CW signal. e.g.: XFIL BW 0.05, FC * 0.53 (all filters adjustments already done) APF : better signal at APF 0.51, instead of APF*0.53 (where I almost loose a faint sig). Tested on WWH, the FLDIGI audio spectrum visually confirms this difference.
No info after RTFM again. Is this difference, however audible, within the specs ? Am I anal ? If not what can I do ? 72, Jean-Marc, FO/F5LCI /"To nobody, except those who will take pleasure here" (Franz Schubert, 1797-1828)/ -- View this message in context: http://elecraft.365791.n2.nabble.com/KX3-APF-tp7578653.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
