We hear this over and over, but it is very misleading. It's true that if you have a good readable signal, a difference of a db or two is not noticeable. But when the signal is right at the noise level or QSBing in and out of it, even one db makes a difference. As N2WN said, it can be the difference between "?" and "N2?" -- or even between the guy CQing again and "?". -- 73, Vic, K2VCO Fresno CA http://www.qsl.net/k2vco ______________________________________________________________ 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
