And Barry reports that additional I.F. gain does help him on some signals, at least.
Your reports suggest that something in the receiver chain is degrading the S/N ratio at lower signal levels. If the degradation is in the second I.F. then additional first I.F. gain would help. I've never seen that before, but I am an "analog" guy not familiar with the characteristics of the DSP system used in the second I.F. Ron AC7AC P.S. CW is just SSB with a *very* narrow bandwidth, Hi! -----Original Message----- Even though I do get a rise in band noise going from dummy load to antenna, I still hear weak signals on my 480 that I don't hear on the K3 on 10 meters SSB. Not sure about cw (what's cw?) :-). Assuming my K3 is set up properly, I would hate to crank up the IF gain just for 10 meters. -- View this message in context: http://elecraft.365791.n2.nabble.com/K3-in-ARRL10-tp5830988p5831388.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
