Re: [Elecraft] Audio dropout
G'morning, Tony: With the NR turned ON, I experience a momentary reduction in audio when turning the SubRx ON.

Re: [Elecraft] Audio dropout
Well, this is very interesting. While I haven't tried ALL the NR settings, I'm STILL not able to get a dropout with NR turned on either. Tony, Ken, can you supply me with a complete list of all your settings when this happens to see if there is some combination of settings that will cause the dropout on my K3. In particular all your AGC settings from CONFIG: menu. And everything on the front panel you have set. Perhaps there is a certain combination that introduces the effect. If you could estimate the length of the drop out in milliseconds, what would it be? 73, Guy.

Re: [Elecraft] Audio dropout
G'morning, Guy: CW Mode, 400 Hz bandwidth with 400Hz filter, AGC-F, abt S3 noise level, NR ON, NR setting=NR F 1--2 Guess about a half second. Not a complete audio reduction to no sound at all, but a perceptible momentary reduction of the sound. 73, Ken K3IU ~~~ On 12/14/2010 10:14 AM, Guy Olinger K2AV wrote: Well, this is very interesting.

Re: [Elecraft] Audio dropout
Well, I don't hear the RX dropping out. What I do hear is the NR resetting and then readjusting. You get exactly the same delay when you have NR off and then turn it on. There is no change in the RF path, as the S meter shows the same level of 160m buzz on input without a drop out. The dropout is independent of AGC. The report is not that the RX drops out, but that turning on SUB somehow causes a slow F 1-2 NR reset in the main radio, as if the NR had been turned off and on. Listening to the SUBRX with the same setting of NR, coming on there is no synch wait, as if the RX turning on is known and the algorithm has a startup sequence. Should the main RX NR get a startup sequence when the SUB is switched on? Wayne, Lyle? Aside from that, you use NR in a contest? Just for long term ear comfort, I hope. I always lose very weak contacts in NR. I holler at the guys at NY4A if I see it on. Lowers the score. The brain is still the best NR for CW and SSB. NB is another story. T 3-7 or 2-7 with IF OFF on key clicks is remarkable. 73, Guy.

Re: [Elecraft] Audio dropout
No, Guy, I don't use NR in a contest. I hardly ever use it at all. Tony was looking for some input, to I tried it out and told him what I found. This is NOT a problem for me at all. 73, Ken K3IU On 12/14/2010 11:05 AM, Guy Olinger K2AV wrote: Well, I don't hear the RX dropping out. What I do hear is the NR resetting and then readjusting.

Re: [Elecraft] Audio dropout
I have version 4.22 firmware. The transition from SUB off to SUB on, and reverse, happens without any dropout. What you describe simply does not happen. When I use N1MM, ***N1MM*** has some kind of transition issue like that. But it does NOT happen from the K3 front panel. Also sending SB0; or SB1; from the command tester tab of the current K3 utility (not involved with any third party software) produces an instant change. This is very easy to test and verify. What is your firmware version? Does this drop-out occur in the context of using a logging program? If so, what program and version? 73, Guy On Mon, Dec 13, 2010 at 9:55 PM, Tony Estep estept...@gmail.com wrote: On Mon, Dec 13, 2010 at 7:32 PM, Luis V.
