Hello All, I have acquired a UHF Mastr II station in great working order. It's got what appears to be a 65-watt mobile type PA (approx 2" high heatsink that sticks out the back) so someday I'd like to upgrade that to a continuous duty model when I run across one.
In the mean time I am wondering how to adapt a battery backup system into this unit. I've got the original 30 amp (I think) GE power supply, where the station gets power from the classic Molex-style connector and the PA gets power through the large fuse on the rear of the unit. What I don't see anywhere back there is any designated place to hook up a battery circuit. I'm pretty sure there are hundreds of these things across the country in amateur service and undoubtedly many of you have made some battery system for this very same setup. If anybody could share how you've worked in a battery backup and some sort of charging system I'd love to hear about it. Thanks all!! Mark Hagler W7WMH Seattle
