Batboard

Hey there,Got a question about the fan on a R1225 repeater. A local volley fire dept. recently lost their antenna site and moved over to our county R&B repeater shack. This is a new unit w battery back-up but the fan runs nonstop on it. I have a GR300 for Ham use and it has a sensor to trip the fan on when transmitter radio gets too hot. Now if the fan is nonstop on their rig and we lost power wouldn't the fan drain their battery back-up pretty fast? I suggested to the fire board that it isn't right but their tech people tell them that is the nature of the beast...... Just wanted to see what some others thought of this. 73 de Jeff/N0SIH

With the battery back-up kit installed, the fan runs continuously. Without the revert kit, it operates as needed. It is, indeed the way of the beast.

Hey thanks HH, I got my GR300 from a defunct Grain elevator and the heat sensor had shorted keeping the fan running continously. I don,t think you could have packed one more atom of dirt in the back of that thing. Just applying that picture to this 1225 and thought it couldn't be good but if thats how it is then so be it. 73 de Jeff/N0SIH
