Dick, The "sensitivity" number is incorrect because the K3 Rob tested didn't have its S-meter and AGC calibrated. He's going to re-test this after the unit is calibrated. We tested a few K3s with new synths in our lab, and all of them had sensitivity very close to the first K3 Rob tested.
On the contrary, the new synth reduces noise considerably over the old (as much as 20 dB lower noise at a 2-kHz offset), which only benefit all measurements. 73, Wayne N6KR On Mar 4, 2015, at 8:56 PM, Dick via Elecraft <[email protected]> wrote: > > Please advise if I am reading the new Sherwood receiver data correctly: > > 1) it shows a nice 6-8dB improvement in 3rd order dynamic range after > adding the new synthesizer? > > 2) it shows that the K3's sensitivity has been greatly reduced from the > original 0.33 & 0.19 to 0.8 & 0.5 after the addition of the new > synthesizer? > If this is true, this would be bad news for weak signal 6 & 10-m. > reception. > > 73, > Dick- K9OM > ______________________________________________________________ > 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]
