Have owned this radio for years and just recently charged it up for use again after nearly 1+ years of non usage. The problem I seem to be experiencing is a steady beep no matter which channel it is tuned to. sometimes simply turning the CTCSS function on/off if tuned to a specific repeater stops the beep but it does seem to re-appear later. even if no particular repeater settings are set and radio is tuned to random channel the beep persists. I would like to know if this is some sort of warning I do not understand or just maybe a problem that has surfaced because if radio age and being idle and not charged for a period of time. Sometimes when monitoring traffic the received transmission is lost and the beeping starts randomly. Any suggestions or help identifying this problem would be greatly appreciated.
