Hi group,
I seem to be having an RF Problem with a new Icom FR4000 Repeater. 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 ???
