I've tried two demos of the P3 inside a building. The first was in a restaurant in Tucson, AZ. We were able to pick up WWV and look at its sidebands, but it wasn't easy! The second was in a restaurant north of Seattle. We finally found one weak AM broadcast station. In both cases we had to connect up a fairly lengthy piece of wire: about 20' in one case and 60' in the other as I recall. In your case, I'd probably bring along a KX1 or some other QRP rig, and a couple of dummy loads, and then observe the signal from your QRP rig. All you can be certain of at the convention center is that you'll pick up plenty of noise from lighting fixtures and who knows what else, and you wont; find signals to demonstrate with :-( At hamfests, Elecraft uses a device that can record and playback a significant chunk of RF spectrum to create a usable RF demonstration environment. 73, Lyle KK7P ______________________________________________________________ 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
