Newbie with Marine VHF Questions

Hey Guys & Gals…

I am new to this so bear with me.

I have a river house in the panhandle of FL only accessible by boat. There are only 911 addresses available for this location. There are no communications available except for VHF Radio. I have a Uniden Um380 Fixed Mount Vhf/2-Way Marine Radio with an 8ft Shakespeare antenna about 20 ft in the air.

  1. Do I need an MMSI?
  2. Do I need a call sign?
  3. Since this is a fixed position, do I need to do anything specific with local laws?
  4. I would like to be able to make and receive phone calls on the VHF. I have read online about this but am unsure of procedures.

Any additional information would be greatly appreciated.

Thanks for the help!

Now I am British and do not know how it goes in the US but I would have thought that all the info you needed would be available from the FCC online.
Certainly here in the UK you need a licence for any marine radio so I would assume the same went for you. But try the FCC ,good luck
