Re: [Elecraft] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes
With this release SSB audio with processor on went very rough...also I can hear funny audio artifact ( on TX monitor ) if I whistle to microphone. After reverting to 4.14 everything back to normal. APF was still great :) Olli OH6CT -Alkuperäinen viesti- Lähettäjä: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] Puolesta Lyle Johnson Lähetetty: 6. marraskuuta 2010 1:33 Vastaanottaja: Elecraft Reflector; elecraft...@yahoogroups.com; elecr...@yahoogroups.com Aihe: [Elecraft] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes K3 beta-test firmware revision 4.18 (with DSP rev. 2.67) 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. This release fixes a problem with low initial output in SSB Tx. See detailed release notes below. Please send any questions tok3supp...@elecraft.com. For instructions on how to load beta firmware, see: http://www.elecraft.com/K3/k3_software.htm 73, Lyle KK7P * * * MCU 4.18 / DSP 2.67 / FPF 1.14, 11-5-2010 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 K3s 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: Youll 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 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 __ 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] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes
Hi Lyle, SSB output is certainly improved in F/W 4.18 compared with 4.17 but contrary to what some others are saying it seems to me still to be down compared with 4.14. This morning I did a tx gain calibration and noted output from the amp under 4.14. I then installed 4.18, cycled power on and off and did another tx gain calibration. With all settings unchanged it was around 15% down on 4.14. Can anything more be done? Credit where it is due, however, the APF feature is excellent, although I do not often use CW so have gone back to 4.14 for now. 73 to all Geoff G3UCK - Original Message - From: Lyle Johnson k...@wavecable.com Subject: [Elecraft] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes K3 beta-test firmware revision 4.18 (with DSP rev. 2.67) is now available. __ 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] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes
Even the mic dynamics came back to normal compare to 4.17, I confirm the same difference between 4.18 and 4.14 and about the APF if moving the Shift to 1khz a big click then nothing. Need to go down to 280 HZ to restart the APF. 73's Philippe A65BI Geoffrey Downs geoffre...@madasafish.com 06-11-2010 19:02 Hi Lyle, SSB output is certainly improved in F/W 4.18 compared with 4.17 but contrary to what some others are saying it seems to me still to be down compared with 4.14.

Re: [Elecraft] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes
Hi Lyle, Did something else change with the way mic gain and bias is handled? Prior to 4.17/4.18 with mic bias set to LOW, I couldn't turn gain up past 5 before ALC started to reduce drive. At a setting of 4 or 5, I'd get 5-7 bars ALC at voice peaks. I always chalked this up to the fact that the MH2 had a hot element. Last night, I got on 10 meters to talk to a friend on a repeater, and noticed that I had to crank gain up to 10 to get the same level of ALC action. Bias is still set to low. I checked on other bands, and a mic gain of 10 now seems to be the sweet spot. Reducing mic gain back to 4, and I'd barely get 1 bar of ALC to flicker. I don't mind this at all, but am curious if other things were impacted and require adjustment i.e., TX EQ settings, compression, etc. Thanks, James K2QI On Fri, Nov 5, 2010 at 8:48 PM, Lyle Johnson k...@wavecable.com wrote: On 11/5/10 5:44 PM, James Sarte wrote: Hi Lyle, Nice work.
