Phil, Your 20-watt dummy load will work with the automated procedure, and it is the best one because if the SWR is over some threshold you'll get a "SWR too high, calibration failed" message.
The 20-watt load is very unlikely to overheat; my 10-watt load did not overheat, because the 50-watt transmissions are short. However, the sure way to make it work is to cool it with a sandwich bag filled with crushed ice. The automated version only takes a minute or so to do and it only has to be done once. If you are unsure, you can follow Wayne's advice and do it manually, allowing some time to cool in between each band. 73, Tony KT0NY ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
