Re: [Elecraft] K3 Beta Release: APF for CW; Fast Monitor improved TX gate for voice modes
Yes APF came out reel good, very well done! Don´t even know if it was this good on the FT-1000D, at least not on the units I did own. Now if only AM RX was to be fixed I would be happy, as it is right now AM (not sync AM) RX is more or less useless. It got broken in the DSP code way back. I have written about this problem before and I´m not going to repeat myself any further. / Jim SM2EKM - On 2010-11-04 00:17, Bill [NS4C] wrote: I loaded the beta firmware so I could see what all the APF buzz was about. 3D2A was spotted on 18070 so I turned the beam and he was there in and out of my noise level.

[Elecraft] K3 Beta Release: APF for CW; Fast Monitor improved TX gate for voice modes
K3 beta-test firmware revision 4.17 (with DSP rev. 2.65) is now available. This release includes our new APF (audio peaking filter) for CW mode, which has been helping K3 field testers work extreme weak DX for the past several days. For voice modes, there's a Fast Monitor option (TX voice monitor without the processing delay). Also included is a much-improved TX Noise Gate. See detailed release notes below. Please send any questions to k3supp...@elecraft.com. For instructions on how to load beta firmware, see: http://www.elecraft.com/K3/k3_software.htm 73, Wayne N6KR * * * MCU 4.17 / DSP 2.65 / FPF 1.14, 11-2-2010 NOTE: Be sure to install all firmware files for this release, including FPF 1.14. Otherwise your menu text will be incorrect. * APF (AUDIO PEAKING FILTER) ADDED: APF provides enhanced copy of weak signals in CW mode, and is especially useful when signals are at the noise level. The K3’s APF is patterned after the most successful analog APF implementations, and is equally effective in user tests. To use APF, make sure CONFIG:DUAL PB is set to APF. (This is the default. “NOR” restores the original DUAL PB function.) Then hold DUAL PB to turn APF on/off. A special DSP graphic display is used to show that APF is in effect. At the time APF is activated, the regular I.F. SHIFT setting, if any, is “frozen,” and SHIFT then controls the center pitch of the APF filter in 10-Hz steps. APF is independent for the main and sub receivers, as well as for presets I and II. Switching between these two presets is a convenient way of turning APF on/off quickly. * ADDED VOICE TX “FAST MONITOR”: Normally the voice monitor includes a ~20-ms delay, which is necessary to hear how your on-air signal will sound (with compression, etc.). If you prefer to not hear any delay in the voice monitor, set CONFIG:TX MON to FAST. Note: You’ll still hear the delayed and processed monitor if you adjust the MIC, CMP, TX EQ or TX GATE settings while transmitting. * TX NOISE GATE IMPROVEMENT: The Noise Gate/Downward Expander for voice modes has smoother response and much improved performance near the threshold. * NARROW AF FILTER IMPROVEMENT: Adjusting SHIFT and WIDTH when using very narrow DSP filters no longer causes ‘pop’ artifacts. __ 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
Re: [Elecraft] K3 Beta Release: APF for CW; Fast Monitor improved TX gate for voice modes
Hi Wayne The APF is fantastic. This is the best enhancement to the K3's receiver ever. The APF performance puts the K3 ahead of every other radio on CW receive. There is just no comparison. Anyone not using a K3 with the APF will be at a huge disadvantage in a contest. The APF is scary with its potential.

[Elecraft] K3 Beta Release: APF for CW; Fast Monitor improved TX gate for voice modes
Thanks so much, Wayne, Lyle and the Elecraft crew who worked on this, and thanks to the alpha and early beta testers. I downloaded the beta version earlier this afternoon and used it for a couple of hours of CW operation. Fantastic! Have not had anything like this since my FT-1000 days. My 7800 APF is a virtual joke. Again, Elecraft continues to provide continuous improvements and enhancements to an already great radio. The K3 continues to morph into the most flexible and option packed piece of equipment I have owned. 73 and thanks again to all for their work and ideas that went into this including the many members here who gave input.

Hi Wayne, never having used this sort of function before, I am pleased with how well it works just the few minutes of playing with it. Thanks much. * NARROW AF FILTER IMPROVEMENT: Adjusting SHIFT and WIDTH when using very narrow DSP filters no longer causes ‘pop’ artifacts. Perhaps I had not noticed them before, but in tweaking on CW using the WIDTH control, I can hear a slight audio pop on occasion which sounds a bit like a scratchy pot and is certainly not the slight drop in audio as the filters are switched in and out. I notice it only when going from 150 to 100 Hz bandwidth but not back again. It does not do it all the time, however. I can repeat it if I widen to about 450 Hz and then narrow it back down to 100 Hz and the slight tick is there each time the switch is made from 150 to 100 Hz. My K3 is a single receiver with 2.7, 2.1 kHz, and 500 and 200 Hz filters installed. BTW, are there filter plots for the Elecraft 5 pole filter available? 73, de Nate -- The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true.

Re: [Elecraft] K3 Beta Release: APF for CW; Fast Monitor improved TX gate for voice modes
WOW!! I wondered who the pile up was for around 14017 or so. Tuning down a couple, I heard an S[minus]1 signal I couldn't make out, sounded like 9A something, sometimes GT[?]. Figuring there wouldn't be a huge pileup on a 9A, I engaged APF. Right out of the noise, maybe S3 and easily copyable was 9U0A. As usual, K6RIM beat me to him. I'm still digesting all the NR/NB/AGC stuff The Smiths sent me, I'm thinking this can only get better.

To use APF, make sure CONFIG:DUAL PB is set to APF. (This is the default. “NOR” restores the original DUAL PB function.)
