[Elecraft] K3 AGC attack rate
Hi Elecrafties. Is it possible to alter the K3's AGC 'attack rate' (for want of a better phrase)? Specifically, I'd quite like to stop the AGC-S on SSB from dropping the gain so markedly in response to a short noise spike. 73 Gary ZL2iFB K2 K3 W2 and mojo __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
Re: [Elecraft] K3 AGC attack rate
Gary, There are several AGC parameters that overlap, so I don't know which one is creating the most grief for you. I encourage you to try adjusting the AGC threshold and slope as indicated in my Noisy K3 article on my website www.w3fpr.com. I would think the slope parameter might be effective in reducing the effect of your local noise spikes. It may be better to let the AGC handle the noise spike, but reduce the delay so the reduction of gain is shorter. A bi of experimentation with all the AGC parameters may be in order. 73, Don W3FPR On 8/22/2011 8:33 PM, Gary Hinson wrote: Hi Elecrafties.

Try turning on NB, with LEVEL to T 1-7, 2-7, or 3-7. Set IF OFF. I use that for key clicks on CW and it's marvelous. I leave NB set to 1-7 that way for use when clicky stuff comes on. 73, Guy On Mon, Aug 22, 2011 at 9:00 PM, Don Wilhelm w3...@embarqmail.com wrote: Gary, There are several AGC parameters that overlap, so I don't know which one is creating the most grief for you.
