If you want to rely on a piece of test equipment it MUST be serviced and calibrated regularly. The Bird wattmeter I carried as a marine radio service tech was calibrated annually without fail, or immediately after I dropped a slug! Banging on a slug it the quickest way to change the calibration. That's why they are kept in the spaces provide on the meter housing when not in use.
All of the Birds I've seen in Ham's hands have calibration stickers many years old. 73, Ron AC7AC ______________________________________________________________ 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 Message delivered to [email protected]
