Re: [Elecraft] [Elecraft_K3] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes
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. 73 Dale, K9VUJ S/N 2268 On 05, Nov 2010, at 18:33, Lyle Johnson wrote: K3 beta-test firmware revision 4.18 (with DSP rev. 2.67) is now available.

Re: [Elecraft] [Elecraft_K3] New K3 Beta Release: APF for CW, Fast Monitor improved TX gate for voice modes
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!

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. 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, ...
