I know we probably all realize this, but the field strength outside of the main lobe from a 250 kW ERP antenna would be a whole less than the field strength from a vertical running 100 watts! I am, of course, NOT saying it is normal to have clicks like he is having. He should not have that problem at that frequency separation and distance even if the beacon is running 1000 watts. I'd be sure nothing in the receiver ahead of the roofing filters is going non-linear, but it almost certainly (unless someone has a very high gain preamp) going to be a transmitter problem. Some of these beacon transmitters are scary, especially when people think they can run CW through a class C amplifier stage. A class C stage, even "unintentional" class C, can make clicks hundreds of kHz wide. 73 Tom ______________________________________________________________ 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
