My 99ch MT1000 just stopped receiving the other day. It beeps when turned on. It will even pick up a transmission when the squelch button is pressed (Although there is alot of static). I was able to read the codeplug thru RSS & all settings seem fine. Any suggestions would be appreciated. Thank you
Antenna connection inside rf deck may be loose.
If that is it, resolder it. .
One very common problem that the MT1000 had, along with its little brother, the HT600's, was that the antenna lug would break away from the board. This can usually be repaired by desoldering and resoldering the lug at the PC board end.
I do not recommend attempting this repair unless you have the appropriate desolder/solder tools, and the skill to use same. There is some risk of damage to the board if it's not done right.
a 6ya expert can help you resolve that issue over the phone in a minute or two.
best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

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:
Press and hold the call key while turning ON the radio.
To turn ON this beep:
Turn the radio OFF and ON again.
Choosing a Channel
Your GMR325-2 radio has 22 channels you can use to talk to others. In order to speak to someone, each of you must be set to the same channel.
To choose a channel:
Press the channel/scan up or down key to increase or decrease the channel number displayed.
Channel Scan Feature
Your GMR325-2 radio has a channel Scan feature that allows you to easily Scan all 22 channels. When an active channel is detected, the unit will pause on that channel until the channel is clear. Then after a 2 second delay, the unit will continue scanning.
Pressing PTT button while the Scan is paused on a channel will allow you to transmit on that channel.
To turn ON channel scanning:
Press and hold either the channel/scan up or down key. The channel number on the display will rapidly cycle through the channels.
To turn OFF channel scanning:
Press either the channel/scan up or down key.
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.
Transmitting a Call Alert Tone
Your GMR325-2 radio is equipped with a call tone that will be transmitted when the call key is pressed.
To transmit the call alert tone, press the call key.
The tone will automatically be transmitted for a fixed length of time.
Auto Squelch Feature
The GMR325-2 is equipped with an automatic squelch system which shuts off weak transmissions and unwanted noise due to terrain conditions or if you have reached your range limit.
Monitor Mode Feature
Your GMR325-2 radio allows you to listen for weak signals on the current channel at the press of a key.
To turn ON monitor mode:
Press and hold the volume/monitor up or down key. The rx icon will blink.
To turn OFF monitor mode:
Press the volume/monitor up or down key. The rx icon will stop blinking.
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.
Note: While in keylock on mode, it will still receive transmissions.
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.
To turn OFF Roger Beep: Press and hold the channel/scan up Key while turning on the radio.
This error message means that there is software/hardware problem. It can be that you have not programmed it in the right way. So, an error occurred while you were programming it. It's better to reset the unit.
Cloning Procedure: (The content of radio A is to be duplicated into radio B)
1. Turn off radio A and turn on radio B.
2. Connect the cloning cable (NKN6376A) to the Universal Connector of both radio A and radio B.
3. Place the PL switch on radio A to the carrier squelch position for full cloning, or the PL position for partial cloning. Full cloning will duplicate the content of radio A to radio B, except for the deviation and squelch settings. Partial cloning is recommended due to deviation variations from radio to radio. (Later version MT1000's (B model for 6, 16, and 99 channel portables; A model for 8 channel) have partial cloning.)
4. Simultaneously depress the PTT and Monitor button on radio A and hold.
5. Turn on radio A. The green LED turns off. Release the PTT and the Monitor button on radio A (HT600's and older MT1000's (A model for 16 and 99 channel portables) beep when cloning is complete). Turn radios "off and on" to reset.
6. Cloning is complete once the green LED turns off. Release both the PTT and Monitor button on radio A. Turn radio A off and on to reset.
For MDC front covers (NTN5456, NTN5457, NTN5458, NTN5459, and NTN6009B), make sure that radio B is turned on before it is connected to the cloning cable.
All VHF wideband radios (146-174MHz) are "C" model radios. A "C" model radio can be cloned only to/from another "C" model radio. An attempt to clone a "C" model radio to an "A" or "B" model radio will result in an unsuccessful cloning attempt.
Any unsuccessful cloning attempt (depending on operating condition of the radio) will result in one of the following alerts:
1. in receive (rotary radio) - 1600Hz continuous alert tone
2. in receive (display radios) - 88 displayed on LCD
3. in transmit - 1600Hz beeping alert tone
