Re: no transmitting with Raymarine Ray45VHF


Re your queries:
1. how to memorize channels?
The channels are pre-programmed that a channel number corresponds to a frequency setting. Ex. Ch16 is 156.800 . If for some reasons some channels are missing, perhaps your best course of action is to reset the unit to factory default, that way everything would be back to  normal. Master reset is performed by pressing the 16PLUS button while powering the radio. The LCD will display "CL" indicating that the memory has been cleared.
If you  want to memorize a certain channel/frequency, you can only store it as a replacement for 16PLUS assignment. Ex. Instead of Ch16 as your priority/emergency channel you want say Ch14 (156.700), you can do this by pressing the up/down key till your desired channel; press & hold the 16PLUS key for 3 seconds or until you hear the confirmation beep that your desired channel has been memorized in the memory as the new 16PLUS.

2. Why I cannot transmit?
There could be 2 possible reasons:
2.1 You are transmitting on a channel that has been assigned as receive only. Examples are the weather channels, Channels 1,2,3,  also 70,75,76, and possibly others.
2.2 Your TX module/circuitry has a problem. More often it is the finals that gets burned.

3. When i use the PTT Channel 16 is automatically set ?
The mic has an identical 16PLUS button (similar to the radio's front panel). If you pressed the PTT switch on the side and the radio switches to Ch16 (as if you pressed the 16PLUS button on the front) then you have a wiring problem from the mic to the radio. Possibly a shorted or open connection.  It is also possible that you have a break in the small PCB (in some versions) inside the microphone.

The user's manual can provide a more detailed instruction.  It is available at the RayMarine website and the link is >

Hope this be of some help/idea. Post back how things turns up or should you need further information.

Good luck and kind regards.

My radio will receive transmissions but will not transmit. It just beps and flashes redlight on top

Hi Kevin,

Beeps and flashes, well my radio does that only if I try to transmit while someone else is using the airwaves already. the radio tells me the Channel is in use, so you can't get on the air until the channel is clear.

Sometimes, some nasty person(s), will hold down their PTT button without saying anything thus blocking the channel with what is known as a 'CARRIER' signal.

Is this the reason you're not making it on air?

I hope this has resolved the issue, if so, nothing wrong with your radio.

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.

I have 2 Motorola P110 2 Ch Radios. One powers up and when I press the PTT button the red light comes on, so I think it works but the 2nd one when I press the PTT button the light is a lighter color of red...

There a a few things which could cause this:

1) You have the radio set to an unprogrammed channel.

2) You have a bad, low or defective battery. (Try switching batteries with the other unit and see if the problem goes away.)

3) Your radio needs repair.

4) Your radio has busy-channel-lock-out activated and you are trying to transmit on a frequency which has activity in your area.

The radios will not transmit to one another.

Check your programming, you may have your interference eliminator set differently between the two radios. Here's a link to the user manual:

Keewood Protalk 2 way radio xls receives , but doesn't transmit

Hello jf1111,

It could be a low battery. Does the screen go completely blank when you attempt to transmit? Two way radios draw a lot more power when transmitting then when receiving so a low battery might cause the radio to cut out when you press the Push-to-Talk and then the radios might appear to turn back on when you release the PTT. If this behavior persists even after charging the battery then the battery or charger (or both) might be defective.

If the battery isn't the issue then the radio could be programmed incorrectly. Does the problem occur on all channels or just one? The Kenwood ProTalk requires dealer programming with a software kit to set the frequencies for each channel. A channel that is programmed for an out of bounds frequencies would generate an error when the PTT is pressed. You might need to have the programming checked out by your local Kenwood Two-Way radio shop.

Best Regards,

I have a Raymarine VHF marine radio but cannot get channel 37 - why not?


To my knowledge, Ch 37 (M1) is used by the UK Marinas and Yacht Clubs, however, the Raymarine Ray45VHF uses the US VHF Marine Radio Channels allocations/standard where there is no Ch 37 (actually no Chs 29-59).

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Motorola Talkabout T6500 will not transmit.

Are you sure the batteries are ok?, try to change the batery, check the radio battery contacts, verify if when you press the ptt, appear an icon on the display that correspond to TX function. Try to use an audio accesory to TX, if all this fail, you should replace it. Good luck
