I have an Icom
IC-M45 VHF radio
that has the following problem. Whenever I hit the mike's transmit button, the unit's display dims by about 50% and the "BATTERY" indicator blinks on the display. I don't have this problem when using using low power
, only high power and it's not a battery
issue since this happens even when the boat is hooked up to shore power
or running with fully charged batteries.
I have had difficulty getting heard on high power but reception
is fine so it doesn't look like an antenna
I can easily replace the radio
but I want to make sure it's shot before I spend the money
Anyone have a possible explanation for this problem? It's not even listed in the user manual...
