This makes sense to me, Bill. It's the noise that excites the ringing, and the TRANSIENT waveform of the noise is almost certain to affect the extent of the ringing. I have VERY limited experience with the Beta (a few QSOs in CWSS with 4.17 and a few more during OK/OM this weekend with 4.21). The waveform of the CW probably also matters -- there was a LOT of flutter on the OK/OM signals here in CA. Some of those OK/OM signals were also quite weak, but I didn't find the APF any more useful than a narrow IF setting in pulling them out. In general, I found the APF to be effective on some signals and a waste of time on others. I also found it tricky to tune in, and thus not as effective in contest operation. As to Joe's measurements -- I've done a LOT of measurements, and I'd call these two sets of data he posted a dead heat. FWIW -- I loaded 4.21 Friday afternoon and ran a couple of hours in OK/OM on 20M Saturday morning and about 8 hours in JIDX SSB.After loading 4.21, I also used a new version of K3 Util to recal TX power. No issues with the Beta. 73, Jim K9YC ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
