A properly equipped K3 or K3S is a good receiver on 630m and as Don pointed out will produce 0.5 mW from the Xverter interface. I've made the mods and checked the output on my 10 year old K3 and it's good to go. There are several amplifier designs on the web that will give 50-100 watts output and I think a few commercially available amps as well. Probably some adaptation needed for the K3 output tho. The real bugaboo is the antenna. A resonant small multi-turn loop is good for receive. The transmit antenna needs a big hi-Q loading coil and as much wire as you can get into the air. That's my sticking point at the moment. I think it's a real opportunity to get back to basics. 73, Brian, K0DTJ ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected]
