I have an ICOM F21GM (same as an F21 without "GM" factory programming as far as I know) that all of a sudden started to emit a loud beep when I key it.
I use it as a GMRS small base station. It sits in a charger all the time and uses an external mike and antenna.
The user manual is vague on the "beep". I think it maybe is supposed to beep when you turn it on, but since it has been on continuously for about 4 years I don't recall for sure.
I am thinking that the battery pack is toast and when I key it the battery pack voltage drops and it power resets itself and "beeps" as it powers back on but I am sort of guessing. It no longer actually transmits when keyed, just beeps.
The charger shows "green" (charged) all the time.
I have a new battery coming but wondered if anyone knew more than me if a bad battery pack is the likely culprit?
