Jeff,
Re: when I cable the xg3 to the kx3, and set the mode to cw, normalize the filters, and set the xg3 to -73 dbm....I read a S-5 reading the S-meter…I would expect a S9 reading. Having a family get-together here, so haven't have a lot of time, but I sneaked away for a few minutes to see what mine read since I noted anomalies when I received my XG3 a couple of months ago. Here is what I found today with my KX3: Initially, with a -73dbm signal from my XG3, my KX3 read one segment (5db) over S9 (40m). Not too bad. Then I increased the XG3 output to -33 dbm, and the S-meter read 25db over S9. Returning the XG3 to -73 dbm gave an S-meter reading of S7 instead of the previous 5 over S9. I have seen this behavior in the past, but… I turned the radio and XG3 off for an hour and went back to it and checked the -73 dbm setting again and now I get S7 consistently. That surprised me, as I expected it to match the 5 over S9 I got the very first time I tried it. I cannot explain why I got 5db over S9 initially. I just tried the same thing on 80m and could not duplicate it there. No matter what I did there, I always got S9 with a -73dbm input. I will probably play with this some more when I get some time, but it is just a curiosity for me since I don’t use the s-meter all that often, and then only for relative readings to get a feel for what the band is doing, or for tuning signals. I don’t often care what the actual number is. Mark KE6BB So many variables between the transmitter and the S-meter, so little time.

I read a S-5 reading the S-meter. all per-band preamp settings are 20db - default (6m is 30db - default) I would expect a S9 reading. ______________________________________________________________ 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] ______________________________________________________________ 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]
