Hi Ian, Most of my operating has been contesting and dealing with pileups. I want to have the most discrimination or differences between different strength signals in the pile up. And it would also like the radio to be as linear as possible. So I would normally use a high threshold and SLP=0 (oddly, that is the steepest slope) so that loud signals sound loud and weak signals weak. On the other hand, for rag chewing in a you might want all signals to sound pretty much alike. Then choosing a low thr and slope=15 will flatten out the signals.
Don has some great ideas on setting AGC in his article, especially regarding noise. It is easy to hear (and see) if you have the THR set too low and noise is activating the AGC. Tune to a noisy band and then start cranking THR down. When you get too low you can easily hear the noise level decrease. If you set up the dBV measurement you can actually measure the reduction in audio level. 73, Fred KE7X ________________________________ From: Elecraft <[email protected]> on behalf of Don Wilhelm <[email protected]> Sent: Monday, November 14, 2016 4:16 PM To: [email protected]; [email protected] Subject: Re: [Elecraft] great article on AGC by Fred Cady Ian, You might also want to look at the information on my website www.w3fpr.com<http://www.w3fpr.com> - Article on "Noisy K3" for more information about how to adjust your AGC parameters for your particular tastes and band conditions. 73, Don W3FPR On 11/14/2016 5:19 PM, [email protected] wrote: > Fred, I have seen your great article on AGC version 4.51 on your web page.I > hadnt seen it before, my mistake.Now I have understood better how it work, > THR and SLP, on K3/K3S.But, sorry, I repeat the question: what is/are the > setting/settings that you prefer?For CW dx-ing and CW ragchewing, > expecially.Thanks Ian IK4EWX > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
