Ok, my bad for being incomplete in testing. I've now pulled the power off of the KAT500 and yes the signal went away completely so it is the KAT500 as the source not one of the other numerous sources around the shack. It is reduced with power off, gone when the power is gone; antenna selection varies the signal strength so perhaps a bit of leakage to the antenna ports?
It is a problem? Not to me, it is only one frequency and so (unnaturally) stable that I can work around it. I'd guess that it is a clock (harmonic) but it's VERY stable with no detectable deviation in pitch to my ear. Most electronic clocks wander at least a little, harmonics much more, this is rock solid. 73, Rick wa6nhc -----Original Message----- From: K1GQ I'm using Elecraft cables for both connections; those cables have beads on each end. I added two more beads to each cable while watching the spur level with the K3 dBV meter; no effect. FWIW, I've heard from two others KAT500 owners that hear the spur but didn't post to the reflector. The spur is obvious on my P3. ______________________________________________________________ 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
