Hi Al, the signal is not the issue, I don't seem to be getting any problems there. What I need is to know what side of the leds to connect, and then I have to get them to a set of relays. I have to be honest here, it's been 15 years since I have done anything with electronics, and my memory somewhere a long the way got misplaced, hi. So now I have the ask tones to set off the weather alerts, but them am told it won't light any of the diodes, so I am going to try it and see just what it will do. So all I can ask is that folks bear with me as I am going to need assistance getting things hooked up. I'm not doing bad thus far, as I ahve gotten the repeater hooked up and working quite rather well. All except for the antenna, was going to try and convert a DB304 to use on the repeater, quite an antenna, but I'm not sure just what needs to be done to get it down to 50 ohms at 146 megs.
