I just loaded this beta version 4.18 and now I get loud crackling from the speaker when tuning though the APF filter, also, the audio goes away. I uploaded the firmware though the P3 twice, once power on P3 and the second time power off with the same results. I will next try loading the firmware directly into the K3. If I have the same result, I will then revert back to the previous version, beta 4.17, which worked fine including the power out.

I loaded beta 4.18 again direct to the K3 bypassing P3 and same problem with crackling audio. I now reverted back to beta 4.17 and all is fine again.

I just downloaded the newest K3 beta release, and don't seem to have
anything like the issue you describe. It seems to work very well! Not sure what to tell you, but unless others indicate a similar problem it may be rig specific. I do notice something else that is odd, and wonder if anyone else has seen this happen. Several times now, since adding the APF feature, when I first power up the P3 I get a screen full of nice big spikes, most of which are false! I center on some nice spikes on the spectrum display, but there's nothing there. However, if I just recycle the power to the P3, the issue seems to go away, and only valid signals are displayed. By the way, I had previously posted that I was having problems with my reference level setting. Initially I was getting a noise floor at -130 dbm or even lower. Turns out I had a bad choke in the K3 (RFC22). Mine is an older K3, and I did have to make the mod to replace R8 with the supplied 13K SMT resistor. Anyway, that RFC appeared to be open, as I was getting no voltage on the low end. I have a replacement SMT part coming, but in the meantime I scrounged up one from my junkbox that is nearly the correct value, and voila! Everything seems to be as it should now. I'm just curious if I somehow "torched" the original RFC, when I replaced R8, or whether it has been bad all along, and it was only the addition of the P3 that made it obvious. Guess I'll never know!

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: [hidden email] [mailto:[hidden email]] Puolesta Lyle Johnson Lähetetty: 6. marraskuuta 2010 1:33 Vastaanottaja: Elecraft Reflector; [hidden email]; [hidden email] 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 [hidden email].

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:[hidden email] 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:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I just replicated your issue on my K3! Once I tuned the APF above 1 kHz the crackling begins. During this time the APF function disappears and with each step on the display a loud CRACK! is heard in the speaker. Once I tune the APF below 270 Hz the CRACK! goes away and the APF is restored. At 1 kHz I hear a loud POP! and then the CRACK! occurs for each step as the knob is advanced to the right although the displayed APF frequency remains at 1 kHz. At 270 Hz I hear a BOOP! and APF is restored. I've done this several times as I've typed this message. When the APF is in the crackle mode, turning it off and then on does not change the crackle state, in fact more crackle is heard upon reactivation. Powering off the K3 while in "crackle" mode kills the crackle and APF resumes its function. I am running MCU 4.18, DSP 2.67, and FPF 1.14 on K3 #4762.

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" <[hidden email]> 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:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

Yes, I was using the shift control. I reverted back to 4.17 and all is ok again.

Make sure you checked 'LOAD ALL' in K3Util when loading f/w into the K3. You must always include the fpf and other files when upgrading. All are in the beta .zip file.

This seems to be an "out of range" issue with the encoder. The APF would normally tune 200 - 1000 Hz and the crackling seems to correlate to turning the encoder past the upper limit. Normal operation can be restored by turning the encoder below 200 Hz to clear the "wrap." 73, ...

Yes, I did that, made sure that all were loaded. V. 4.17 works FB. V. 4.18 is a problem with my radio.

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" <[hidden email]> 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. 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" <[hidden email]> 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:[hidden email] 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:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html |

I think Joe is on the mark that it's an issue when the firmware is reading the encoder and gets into a glitch at the upper end. No biggie, just keep the AFP below 1 kHz. I had yet to advance it past 800 Hz or so prior to your post on this matter so I started playing with it to the extremes. 73, de Nate >> -- "The optimist proclaims that we live in the best of all possible worlds.

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 <[hidden email]> wrote: > On 11/5/10 5:44 PM, James Sarte wrote: > > Hi Lyle, > > Nice work.
