Re: [Elecraft] NR & AGC
Before, activating NR reduced the signal strength and sometimes drastically. A few of us asked to put NR and NTCH inside the AGC loop to keep teh signal strength even. It seems as if the firmware upgrade just increased gain with NR but NTCH is definitely not inside the AGC loop yet. Ignacy hello all, Anyone try this: listening a S7 to S9 signal (SSB) on any band with your headphone, at this time, try to enable NR, you will hear a really LOUD audio! Maybe need firmware upgrade to fix it. 73s David BA4RF __ 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 -- View this message in context: http://n2.nabble.com/NR---AGC-tp2602826p2608887.html Sent from the Elecraft mailing list archive at Nabble.com. __ 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] NR & AGC
Confirm this one also, I dont operate SSB but tuned in a couple stations to try it out and it will blow your ears off when you hit the NR button. Did not reload older software to see where it took place but its new on the last release or so. Merv KH7C > I can confirm this.

Re: [Elecraft] NR & AGC
I can confirm this. I've heard it on strong SSB signals and it's easy to demonstrate with the XG2 signal generator set to the 50uV level. The more aggressive the NR setting, the louder the strong signals become. Using the XG2 and the K3's built in AFV meter, NR F1-1 gives a 3.1 dB boost and NR F4-4 gives a 16.4 dB boost. 73 -- Joe KB8AP On Apr 7, 2009, at 7:47 PM, chen dave wrote: > hello all, > > Anyone try this: listening a S7 to S9 signal (SSB) on any band > with > your headphone, at this time, try to > enable NR, you will hear a really LOUD audio! > Maybe need firmware upgrade to fix it. > > 73s David BA4RF > __ > 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 __ 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
