There is nothing wrong with Hamtronics modules that have been built in the last 15 years. Their controllers (COR Modules) suck, buy something modern like an NHRC, Arcom, or something else. > As for energy efficiency I've never seen a modified mobile that would > operate at 20 watts with just a few amps input. > Unless you have seen my Micor conversion that will do 17 watts with just two final stages... The whole repeater including controller, preamp, etc. running 17 watts draws a little over 3 amperes at 13.8 volts DC. Yes, there is a switch in the B+ line for the audio PA, and yes, at this current draw it is turned off. Pictures of a similar PA are here: http://www.shol.com/kuggie/ahra/hmftinfo.html Kevin Yahoo!
