I have had a similar experience on 3400MHz EME. I used a 12V wallwart to power my DEMI 10-4 10MHz splitter after my LPRO101 Rb Standard feeding the K3 and the 10MHz locked Xverter. I got complaints from 3 continents that my signals off the moon had 120Hz sidebands!

I am using a Morion OCXO as 10-MHz reference for my K3EXREF and for my synthesized A32 PLL in my DEMI 1296 transverter. I got reports of 120-Hz sidebands on my signal (-10dBc) turned out to be due to excessive AC ripple riding on the 12v coming from my wall wart supply that I was using to power the OCXO. 73, Ed - KL7UW ______________________________________________________________ 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]
