[Elecraft] K3S CW AGC-F Not Working?
All: I noticed that he AGC-F setting on my K3S seems to have no effect when in CW mode yet it works in SSB mode. When switching between AGC-F and AGC-S the decay is slow so it appears to be "stuck" in the AGC-S setting when in CW mode. The AGC settings are: AGC DCY = SOFT AGC HLD = 0 AGC PLS = NOR AGC SLP = 10 AGC THR = 10 AGC-F = 130 AGC-S = 8 The rig (SN 11829) was factory assembled. Any ideas?

[Elecraft] Elecraft CW Net Announcement
Good Evening, After two weeks a new sunspot has appeared. We are also in a stream of solar wind. Our ionosphere is being refreshed. The auroral oval is strong at the moment. Hopefully things will settle down a bit for tomorrow. Noise levels are still fairly low maybe the signals will pop out. I expect both bands to change during the nets due to the time of year. Twenty meters has been getting longer but I'm reaching different parts of the US. By the time the snow stopped falling I had about a foot. Even with the rain there is still a three to four inch covering. One morning I turned the faucet only to hear a gurgle. I slogged through the sloppy snow to the pump house only to find the relay stuck on. OK, a reset. But that didn't work. Neither did my confused glare. So I shut off the power to the pump and did other chores. A few hours later I turned the breaker back on and reset the relay. A few iterations of that and now the water is running. For some reason it thought the well had run dry in the rainy season. Maybe the confused glare helped. Please join us tomorrow on: 14050 kHz at 2200z Sunday (2 PM PST Sunday) 7047 kHz at z Monday (4 PM PST Sunday) 73, Kevin.

[Elecraft] Sudden KpA1500 power reduction
I'm in the ARRL CW contest this weekend and the KPA1500 has been working fine. However, a few minutes ago I noticed I was getting about half the output power on 20 meters that I typically get with around 30 watts drive (about 600w vs 1200w). PA current is less than normal, around 30a. Similar problem on the higher bands, I can no longer get 1000w. On 40m I can, but it requires more drive. Seems like something died in the amp; I'm not familiar with the design, but perhaps an output module. No errors or ill behavior from the amp other than the loss of power. I will contact Elecraft support unless there is something I'm missing here. I just looked in the archive and see that this has happened to others I use the amp remotely so I guess I'll have to take it home with me.

Re: [Elecraft] Big Knob Fail
Even though your s/n is 21, it was not the first K3 kit shipped. I have the first K3 kit shipped, as I assembled the very first one, outside of the beta testers. I also have the original knob and encoder.

Re: [Elecraft] K3s USB audio problem; both channels identical
As a side note This problem usually is caused by the Windows updates. The update will change the audio codecs in your Windows Sound system. So check the settings after an update to make sure Windows did not change them again.
