You want exactly the opposite to see weak signals. The scale setting is the DIFFERENCE between the top and bottom of the display. 150-180 dB is very INSENSITIVE. You want a very SENSITIVE setting, but no so sensitive that it gets blown away by big signals and noise. I usually set my scale at 42 dB for contests, where there are a lot of very strong signals, and at 24 dB for routine operation. I find that 24dB shows weak signals that I can't hear It's VERY important that AVERAGING be ON, and set for it's highest setting. A scale of perhaps 12-18 dB is about as low as I would go for showing very weak signals. 73, Jim K9YC ______________________________________________________________ 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
