I am assuming that you are speaking of the charger. The Red LED shows that the charger is plugged into the wall. It does not show the charge status of the radio. These are very simple units, and it is not a "smart" charger.

25 hours is in standby only, not with receiving or transmitting, both draw much more current off the batteries

Check your batteries. Static can be a sign of a bad or low battery. Swap batteries between the units to see if the problem moves to another radio.
Also, check your antenna and antenna connection.
Best regards.

Press the channel/scan up or down arrow key to change3 the channel on either radio. Need the operating instructions? You can download/print them here:

Hi Zachary
I predict that you have trouble with only one unit.
Try to find some one with either the same units ( on same Frequency of course) or a receiver that also covers same Frequency and transmit on one GMR then the other to esablish which unit is faulty!
The faulty unit should then become apparent, the buzzing could be caused by transmisson of the faulty unit, check all Antenna connections, even change antennas over on testing as prescribed above,
good luck John.

Bad transmitter, you might need to get a new set.
