After working in communications for the State Police here in Michigan for 37 years, most of our equipment was from Motorola, and we have had several problems with silver mica capacitors made by a company that marked there components with 'EM'. If you find a circuit that is in suspect of causing a problem, and there is silver mica caps with 'EM' installed, replace them. Many of our Motorola Micor radios had freq shifting and intermittant drive which caused erratic power output. These 'EM' caps apparently had a contamination when they were made and some didn't go bad for several years. I would certainly check for these parts in the PTO's that are operating intermittantly. I hope this helps...
Good luck and 73, Ski-WB8YXI _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
