John, Maybe the impact of the APF is a moving target influenced by the band conditions at the time? Yesterday morning 160M was very quiet. I could not hear the VK6 without the APF. When I turned on the APF the VK6 popped out of the band noise and was easily copyable. There was no hint of ringing even with the bandwidth down to 50HZ.
Last night as usual in the evenings here 160M was noisy. When I turned on the APF it still did its magic. But there was almost a trace of "ringing". I need to play more with it to see if it is a definite pattern comparing between quiet and noisy band conditions. Also I think I should install 4.14 in my second K3 to compare the two versions to see if I hear the difference you are hearing 73, N2TK, Tony K3 #311 K3 #1435 -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of juergen Sent: Wednesday, November 17, 2010 3:17 AM To: [email protected] Subject: [Elecraft] K3:New APF what happened? Hi I was so impressed by the original K3 APF firmware. Why is it so lack luster in the current beta? I have read all the posts that there is no difference, my ears tell me different? When I used the APF in its original release on 160m and 80 meters it just blew me away to mars and back. Now I might as well not have it on! The signals dont "pop"out of the noise like they use too. I might have to have my ears cleaned and checked for wax or something. I am mystified especially when Lyle says that there is no difference in the firmware. The K3's APF in the current beta behaves much like the one in my Icom radios and they are very ineffective in the Icom radios. I have shifted back to the old beta 4 times and the results are better for the old APF and it wins hands down. I will keep the old beta just for contests, its just too good not to use. 73 John ______________________________________________________________ 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 ______________________________________________________________ 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
