GM300 Signalling option

[cmanila2008]

I have a GM300 8channel VHF radio 146Mhz-174Mhz without the signalling option. I tried using the RSS to program the radio but the signalling option is not available, is there a way to add or program the radio or activate the signalling option. I am also thinking of cloning the radio but I need a working codeplug with the signalling option activated. Is there anyone here who have the needed codeplug? or any idea on how to activate the signalling option. any help would be appreciated.

Thanks

The lower tier radio logic board/uP does not support signaling. You would need the expanded logic board.
