Is An External PA System compatible With My Radios?

[YPSILANTI]

Greetings.

Please can the radio boffins out there advise if any of my 3 radios can accommodate a external PA / loudspeaker system/ i.e. Can I talk through my existing microphone through an external speaker mounted of my fore deck to communicate with my crew or a nearby vessel. I have a speaker mounted mid-way up my mast. It seems that my boat once has an such a system but possibly with another radio.

My radios are as follows:

1. ICOM HF Marine Transceiver SSB IC-M600
2. ICOM VHF Marine IC-M304
3. GME GX 300 VHF.

The two ICOM radios are a few years old.

If any of the above can accommodate an external loudspeaker system, how to I go about installing it.

Thank you.

Regards
Mike

I'd suggest looking up your manual for your equipment and reading. A quick google search should do it.

I did a quick search which didn't bear any fruit. I might have missed the relevant note though. Lots of reading. I'm sure someone out there will comment if they have one fitted to their radio that matches any of mine. Appreciated.
