The K3 manual provides 0/2/4 as suggested values. The filters in your radio, as determined by the factory calibration procedure, must have needed more gain. What is better Wayne? Can I use on my great K3S 0dB-2dB-4dB? Or you prefer > other settings? > You can change the Flx gain values and hear the sensitivity of each filter go up and down. Ideally, signal strength should not change as you switch between filters. The K3 Utility provides an RF Gain calibration procedure too (requires a signal generator). > Sometime I like to use my old Cubic Astro 102BXA, yesterday on 10 meters, > with a bug. > How can be that this rig, 35 years old, have the best agc and a great qsk > even for today standards? > How can one define "best AGC?" Define "more pleasant." Maybe you can post an audio recording made from the headphone jack with an isolation transformer so that we can hear what you're hearing. Have you tried changing the K3's AGC settings from the factory defaults to the values recommended here <http://elecraft.365791.n2.nabble.com/K3-Receiver-mush-tp7627277p7627323.html> ? As for QSK, T/R turnaround time is probably better in the Swan rig because it doesn't have any digital signal processing, so no latency added, so no delays waiting for buffers to fill before the receiver hears signals between elements. But no DSP means limited noise reduction, limited notch controls, no adjustable noise blanker, etc. You can't have everything. 73, Bob, N6TV ______________________________________________________________ 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]
