I have an Icom
IC-M504 VHF Radio
transceiver. If I turn my squelch up to 3 (which is just barely enough to eliminate static), I can't receive any voice communications
. People can hear me, but I cannot hear them. When I turn the squelch down, just slightly, I can hear communication, but I also hear the static when there is no one talking. Is this an antenna
issue, a bad setting in the VHF
, or just a fault in the radio
I have a mast
and I don't like to go up there unless I have to. I don't have a spare antenna. I tested the antenna and the coax in the following manner. With the squelch set very low, I tuned in a weather
station. The weather
station doesn't come in at all on my handheld VHF so I am getting some benefit from the coax and/or antenna. I removed the antenna connection from the radio and lost
the signal. When I put the male portion of the coax back into the VHF, the signal came back. When I fully connected the coax to the back of the radio there is no change, neither improving nor getting worse. Seems like the signal should get better with a full connection. My question remains, is this a bad antenna or a radio issue?
Thanks for any assistance.
