OK. www.foothill.net/~andreaj/WWV_7KHz.bmp This is a 7KHz span with the marker on the first sideband [high side]. You can see the 2nd and 3rd harmonics, and maybe the 4th although that might just be noise. www.foothill.net/~andreaj/WWV_100Hz.bmp This is the carrier at a span on 2 KHz. The marker is at 100 Hz which is the IRIG-H subcarrier. The peak between it and the carrier comes and goes and I guess is the sideband from the time code modulation [actually, I just made that up, I really don't know] www.foothill.net/~andreaj/WWV_1KHz_beep is the 1 KHz beep at the start of each minute. The marker is at 500 Hz above the carrier. My baseline was wandering just a little when I snapped the screenshot, sorry. WWV 10 MHz was running fairly steady at 10 over S9, some QSB. On CW, with DSP at 50 Hz, I can tune to each of the sidebands and their amplitude on the S-meter relative to the carrier sort of matches the P3 display ... this is a moving target, it's hard to be exact. Explanation welcome, guesses will be added to the growing list. 73, Fred K6DGW - Northern California Contest Club - CU in the 2012 Cal QSO Party 6-7 Oct 2012 - www.cqp.org ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
