On my Motorola repeater it is the tx oscilator, to get rid of the problem I turned on PL on the TX and my HT, when it isn't repeating it doesn't generate PL so it is muted. Thats the only fix I know of - Rob

The repeater is letting out a hissing noise when I listen to it on a HT or my mobile radio. The hissing noise sounds more like a squelch that is opened up. When I get about 300 feet from the repeater the noise is gone. It does not key the transmiter. This is why I am puzzled. The only way I have found to get arround it is turn my squelch way up on my HT to remove the noise. When I key up my HT the noise drops out while the repeater is transmitting. The repeater and repeater tower is at my home. If it was several miles out of town I would not be emailing you. I have mounted it in a metal case, grounded the repeater by the grounding screw, grounded the coax by twisting copper around the coax sheild, grounded the repeater cabinet. I first thought that the problem was from the duplexers. Not so, I took the duplexers out of line and still noise. The only way to remove the noise is to turn off the repeater. Something I don't won't to do. Any thoughts ???
