I've >> been listening to that buzz for decades. incorrect .... the above is the colorburst frequency and you list the correct freq as 3.579545. the vertical rate is 60 Hz, the horizontal rate is 15,734 Hz. The above does not matter if the set is solid state or (old tubes). It is usually the "flyback" (HV transformer that helps generate HV and horizontal scan rates among other things) the radio hears. And some people with sensitive hearing can also hear it (really). 72 Ron, wb1hga ______________________________________________________________ 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
