Maybe the S-meter needs to be calibrated as per the manual after the RF Gain test? With no antenna attached on 20M I get no reading on the S-meter. With the antenna connected and no signals the S-meter kicks up to about S3. With a 50uV. signal the S-meter reads S9. That seems correct.

I was going to make the same adjustment with my K-3. But if you are getting a 3-4 s-unit higher noise level after the adjustment has been done... I won't be making the adjustment as my K-3 is already more sensitive than I need on the low bands. I'd use a 20dB ATT on the low bands often if I had one available. Perhaps one day we'll be able to change the K-3's RF Gain per band via software to help adapt to our local noise environment. (mine is very noisy on the low bands with thunderstorm QRN off the Atlantic). For those who may be concerned, yes I do use the RF Gain control. 73, Dick- K9OM Sorry if this comes across more than once, I'm having some e-mail issues. I just did an RF gain calibration, using the XG2 and the K3 utility on my kit K3 (built in Sept. '09). There seems to be a dramatic difference in my noise level, 3-4 s units, with a calibrated s-meter. I think I can pull more stuff out of the ditches and weeds now. Does that seem reasonable? 73, Mike NF4L ______________________________________________________________ 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 ______________________________________________________________ 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
