I did a second experiment that gives another perspective: http://n1eu.com/k3/ha8bt_apf.wav
This time the K3 selectivity was 50hz before applying APF. The conclusion I come to after listening to this recording is by narrowing K3 bandwidth down to 50hz, you gain most of the benefit of the APF. (the APF center frequency was adjusted to match the received signal) 73, Barry N1EU Barry N1EU wrote: > > Okay - hear a simulation of the effect of K3 APF for yourself: > > http://n1eu.com/k3/rz0af_apf.wav > > -- View this message in context: http://n2.nabble.com/K3-honest-question-re-Audio-Peak-Filter-tp4237359p4238076.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
