I had the same problem with both red lights going on..............
When I key the mic and get an incoming transmission it makes a long schrill beep. But it works OK when there is a truck right next to me standing still in the yard (about 50 feet next to me.) My truck is brand new. I called Uniden and they said, a bad antenna connection? Or a defective radio?
I bought the radio brand new two days ago at a truck stop a hundred miles from my home. Please Help. Thanks.

perhaps the squelch is set too "open". Try to program a tone code into the radios. Many times the manufacturer expects you to use a tone and they set the squelch too high, or open. This causes the squelch sound because the radio is trying to pull in weaker signals. If you are using a tone code, the model of the radio is needed to tell you if the squelch can be adjusted.
In order to get the most out of your new radio, read this reference guide completely before attempting to operate the radio.
Turning the Radio On and Adjusting the Volume
1) Press and hold the key to turn the radio ON.
2) To change the volume level press the volume/monitor up or down key to increase or decrease the volume level.
3) Press and hold the key to turn the radio OFF.
Adjusting the Sound (Key Beeps)
Your radio emits a beep each time one of the keys (except for the PTT button and call key) is pressed. The sound of the Key Beep will increase or decrease depending on the volume level setting.
To turn OFF this beep:

Talking on Your Radio
To talk to others using the radio: 1) Press and hold the PTT button and speak in a clear, normal voice about 2-3 inches away from the microphone.
While you are transmitting the tx icon is displayed. To avoid cutting off the first part of your transmission, pause slightly after pressing the PTT button before you start talking.
2) When you are finished speaking, release the PTT button.You can now receive incoming calls. While receiving, the rx icon is displayed.

Automatic Power Save Feature
Your GMR325-2 has a unique circuit designed to dramatically extend the life of the batteries. If there is neither transmission nor an incoming call within 2 seconds, your radio switches to the Power Save mode. The radio is still able to receive transmissions in this mode.
Press and hold the call key until the "L" appears. After 1 second, the LCD will return to the channel display. To exit Keylock on mode, press and hold call again.

Roger Beep is a BEEP that is sent to notify the end of transmission. Roger Beep can be heard through the speaker when Key Beep is on. Roger Beep is transmitted even if key beep is turned off. However Roger Beep will not be heard from the speaker.

Does the roger beep come with instructions? It can vary between beep boards.
Typically it gets installed inline with the mic jack.
There is a wire or pin on the board where the tx wire, and the rx wires go.These wires get disconnected from the mic jack, then a wire goes to the tx pin. Then there is an audio wire that gets connected to the audio wire of the mic jack. Then the black wire to ground, and the red wire to switched 12v right off the power switch.
