Wayne released APF to Field Test last night and also said it was OK to post comments. It seems to work very well and I expect it will be released publicly soon.
APF (as implemented in the FT-1000) has always been a weak signal receiving tool. It's not for adjusting PITCH or some of the other ideas discussed. Last night I happened to be listening on 160m around 02z just after I got it installed. 5R8RJ usually comes on 1826.44 a little before his sunrise. Conditions were very poor but he was spotted by a UA4 around 0210z. I could hear nothing of him on his normal frequency. CW Skimmer's waterfall was also showing absolutely no signal there...not even a faint trace. I then actuated APF and could then copy him about Q3 in the noise. This is exactly what APF is designed for...pulling extremely weak signals out of noise...and it does it very well. The user interface is also very simple. Although it may change slightly before public release, you hold DUAL PB (as though you were going into the previous CW focus mode) and then adjust SHIFT in 10 Hz steps to peak the signal (independent of your PITCH setting). It works well in diversity also. Nice job guys...all the previous FT-1000 owners will rejoice! 73, Bill W4ZV -- View this message in context: http://elecraft.365791.n2.nabble.com/APF-in-4-16-2-63-works-well-tp5686011p5686011.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:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
