Thanks Mike. I think I may already have a solution and will more than likely replace the RICK with a different controller that has a power fail monitor already on it.

Please don't use a 555 - they output square waves .... which sounds bad and if the TX audio filtering / deviation control isn't what it should be they will cause adjacent channel interference. A simple sine wave audio oscillator is not that difficult - a transistor, a audio transformer, and a few resistors and capacitors. In my initial response I didn't suggest keying the TX PL encoder simply because that may already be in use, and using it for a power fail alert requires hooking some kind of an alarm to a PL decoder somewhere. My offer to engineer a real solution still stands - just get me a RICK manual or a copy. Mike WA6ILQ Yahoo! Groups Links Yahoo!
