Spectral power density is a good way to express how to deal with this. It is how CDMA cellphones use very low power, but lots of bandwidth, versus TDMA (GSM) which use high peak power, but less bandwidth per call. For a given cell band, CDMA can handle more calls. SO for a given Amateur band... Of course, it quickly gets very complex :-) 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
