3579.545...kHz is the color subcarrier frequency in the NTSC (analog) color television system which was used in the US and many other countries for both tube-type and solid-state receivers. It is not used in current digital TV systems. See http://en.wikipedia.org/wiki/NTSC for more than you ever wanted to know about NTSC. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 ______________________________________________________________ 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
