Stupid question, but is anyone selling little dummy loads (only needs 1 watt max, after all) built into the various types of antenna connector that these radios use? I suppose you could just take a 1W carbon resistor and solder up your own, though it would leak a bit. (I remember the original Cantenna. This wasn't a Pringles can. It was a dummy load, made by Heathkit, consisting of a gallon or so metal can filled with oil that cooled some big resistors. An SO-239 was on top and it could absorb a kilowatt for a brief test, or a smaller load for a longer time. I did watch somebody smoke one with a serious 2-meter grounded-plate amplifier. Those 8877 tubes were great. It was a very generous kilowatt amp.) -- Fred Goldstein k1io fgoldstein "at" ionary.com ionary Consulting http://www.ionary.com/ +1 617 795 2701 -------------------------------------------------------------------------------- WISPA Wants You!
