An odd thing happened today, I was tuning through an area on 20m where I
have a birdie, about 14.270-14.273. The noise reduction was on at 1-3 I think, I don't know what state the notch filter was at or the noise blanker, as I tuned into this area the audio was a bit odd, like screechy, I didn't think to much of that because of how the noise reduction works around birdies, but it was different than I had heard in the past. All of a sudden the volume in the headset and the internal speaker went to max and turning the volume control had no effect. I shutdown the radio to avoid damaging things and when I turned it back on everything was fine and I can't make it do this again. Very odd (and painful), wondering if this has happened to anyone else.

Now I can make this happen repeatedly, with the NR at 1-4 and the notch
filter on auto as I tune across the birdie the volume goes very loud, it is louder than any noise I can get the radio to do normally with the AF all the way up. I have discovered that this only does this in the NR 1-1 to 1-4 range, very repeatable. As you tune through the birdie the radio starts making a noise like caddisflies (moderate high pitched fast oscillation) then it becomes very loud white noise. I don't spend anytime playing with the controls but I know the AF does nothing. I copied this to Elecraft tech support. MCU (uC) 03.27, main DSP (d1)2.24, aux DSP (d2, if KRX3 is present), flash parameters (FL)01.02, and KDVR3 controller (dr )01.03. This is very loud, be careful!!

This same thing happened to me this morning. I had headphones on and it
really caught me by surprise. I passed it off as something I probably did, but apparently it is an issue. I may have been at the same NR selection, too. Very odd.

Please download the latest beta test code off the web site
(k3fw3r27a.zip) and replace the DSP 2.24 code with the newer 2.25 DSP code. (The mcu version stays the same.) This is the issue we addressed when we changed the dsp from 2.24 to 2.25 late in the week. 73, Eric Bob W Allen wrote: > Now I can make this happen repeatedly, with the NR at 1-4 and the notch > filter on auto as I tune across the birdie the volume goes very loud, it > is louder than any noise I can get the radio to do normally with the AF > all the way up. > I have discovered that this only does this in the NR 1-1 to 1-4 range, > very repeatable.

Apparently this was not the fix, they (Lyle and ??) are working on it
now. Watch out it is a very loud noise especially with the head phones on.

Bob:
"The Birdie"? What birdie are you speak of that we too might tune across it. I have this urge to listen to caddisflies.

Any strong unmodulated carrier seems to work. Theses are the things that
you would use the autonotch filter for. Not sure if this sounds exactly like caddisflies but I saw a horror movie 25-30 years ago that when bad stuff was going to happen the caddisflies would all start making a very loud noise that sounds like this. Watch out for what follows, very loud and you can't turn it down, have to power off. Bob KB1FRW Steve Ellington wrote: > Bob: > "The Birdie"?
