Thanks, I may continue to run with just one screw. I searched for a while for a screw to match the specs given earlier, but haven't found any. My FR with 2 screws gets much better reception the the FR with 1 screw (the 1 screw is placed to make the antenna contact, so the missing screw may b

I suggest using double-layer super capacitor* intead of Lithium backup battery. These capacitors stores energy for a long time, like a battery and they have much longer lifetime. 0,2 F capacity should be enough for RTC backup on several hours, maybe days. * http://cz.farnell.com/jsp/search/browse
