Thanks Dave,
Easy to forget something, but both are the same, ATT=OFF, PRE=ON I just tested it on all bands: same results on all bands. (May be only S-meter offset if possible ?) 73's, Evert PA2KW _____ From: David Gilbert [mailto:[email protected]] Sent: Monday, March 16, 2009 20:24 To: [email protected] Subject: Re: [Elecraft] "Hot" K3 You didn't mention ATT and PRE. I have found that sometimes when I reset my K3 it goes back to settings that turned one or the other on without my being aware of it. 73, Dave AB7E Evert Bakker (PA2KW) wrote: Hello Don, I do have a similar effect except that my first and second radio is a K3 (SN-0812 and SN-2185). - Same power-supply at the same time radio's ON - both on 50 Ohm dummy load - same roofing filter (2.7 Kc) - same filter gain (0 dB) - same DSP setting (Bw = 3.0 Kc / Fctr = 1.5 Kc) - same rx equilizers - same AGC settings (AGC-F, THR=6, SLP=5) - no S-meter changes (settings are factory default) - same RF gain setting - KRX disabled in SN-2185 - Both KANT 3 disabled and ANT 1 selected Result : 2 to 3 S-units difference (+/- 15 dB) on "internal" noise difference. This was the first test on 15 meter) That's a lot. How come? I can't say anything yet about the sensitivity. I will try to find someone with a "calibrated" signal source and make conclusions. It might all be differences in gain, but first of all I have to gain confidence... Has one of you a good suggestion a-priori? 73's, Evert PA2KW ______________________________________________________________ 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 ______________________________________________________________ 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
