GME GX300 Marine Radio

[Pete & Jim]

Recently purchased a GME GX300 Marine/CB radio, could not get it to communicate with the car CB, went out on Sydney Harbour, kept trying for a radio check, but couldn't get anyone to answer.  Thought the aerial might be the problem, so purchased new 27mhz aerial, still nothing, does anybody have any ideas?  Or what to do next?

apparently the 300 has both 27meg and cb band  make sure you are choosing the right channels for 27 if you have that aerial...rick

If your display is showing 1 to 40 for channels then you are in car CB mode if your display is showing 68 to 98 then it is in Marine mode.   If I remember right you turn on the radio holding the priority button to change between the 2.

 

68  Commercial, ship-shore-ship

72  Professional Shipping

82  Professional Shipping

86  Secondary distress and safety

88  Primary distress and safety

90 Domestic ship-shore-ship

91  Domestic ship-shore-ship

94  Club events, ship-shore-ship

96  Ship to ship

98  Rescue organisations

Don't transmit without an antenna it could do damage to the radio.

ps  hardly anyone uses 27meg anymore  vhf has taken over  further north 27meg isn't monitored by coastal patrol anymore.....I havnt used 27mg in four years as we were warned then it was being phased out..rick

Marine Rescue still monitor 27MHz, but fewer boaties are using it. VHF is a better option.
