I need an internal wattmeter for a homebrew, legal limit, solid-state amp. Except for the fact that the W1 only takes up to 140W without modification, it looks like a great solution. I'm thinking about using a surplus bridge from an industrial ISM generator and "padding" the DC output by 12-dB before feeding (via miniature coax) to the junctions at D1/R3 and D2/R4.
Can anyone think of a reason that this would NOT work? Also, if I simply change the voltage at TP1 by adjusting R17, does the entire power range follow, or does the accuracy suffer at one end of the range or the other? Thanks, Brian K1LI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
