I would be VERY VERY interested in how you can reliably resolve the difference between 110 watts and 106 watts, or even how you're certain it's 106 watts. The accuracy of a Bird 43 wattmeter is 5% of full scale. To measure 106 watts you need a 250W slug. 5% of that is 12.5 watts. Where did you get that slug? Do you have any assurance that it was calibrated? Perhaps another wattmeter? Has it been calibrated against a known standard? Do you know the frequency response of that meter? That is, if it's calibrated at 14 MHz, is it also correct at 28 MHz? At 50 MHz? How do you know? That is, what voltage or current reference are you using to determine it? When and where was that voltage or current reference last calibrated? 73, Jim Brown K9YC ______________________________________________________________ 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
