This should do it easily. Has enough amperage available to transmit if desired. Not that doing so is legal. The one you posted would also work well, just a bit more expensive, but much more versatile. Basically like an old Radio Shack power supply. I have one in my garage powering an old car stereo hooked to some 6x9's.

That will work fine. You might get a little buzz in the audio with some of the DC converters, but if you do you can filter it out. That will provide enough power to run virtually all marine radios as long as you're not transmitting.

You could also use a small 12v battery with a small charger/maintainer.

You can use an old battery if you don't have a converter lying around

I used a throw away radio, battery and a $20 antenna for 15 years in old place. Whenever I was on roof I just wrapped the antenna with more duct tape for strength

For those above do you just cut the connector off and connect the wires to the radio? Does it need a fuse?

For garage use in the winter and colder climes, the wires can double as a space heater when you get rid of the fuse. Sometimes also as emergency lighting but usually only for very brief periods or assisting low light photography.

forget the {/sarc}?

It's always good to put a proper fuse in there... can protect both the radio and the wiring in case something goes awry.

Which connector are you talking about cutting off? Most radios have a connector to go into the radio and a pigtail to connect to power. You just connect the pigtail to whatever source of power you have.

You need 7+ amps to transmit. But that will be fine to receive.

as above illegal to use marine radio on land.

I have a little 7ah ups battery and small 1a charger on my house Ham radio. So it could be used during power outages or disasters.

So my home vhf and antenna that I call vessels on all the time is illegal. Actually I even call the CG sometimes so I'll remind them next time that this is an illegal call.

Where is said antenna in garage... I have thought about doing this and if you use car battery for 12v how long does it last or if I do in future tiki bar.

The connector on the power device, not on the radio. I know all about wiring a VHF on the boat just wasn’t sure about hooking it up to a power source like that. I was asking about the fuse because I wasn’t sure if you’d have the same worries about surges when using a reliable power source. I think I understand now how to set it up.

I saw a show on tv where they used a bicycle made from bamboo and twigs connected to some coconuts and the coconuts powered a radio, maybe worth a shot

And doesn’t land based coast guard stations monitor VHF, as well as marinas, bridge tenders on land ,fuel docks , harbor masters, Sea Tow office, some water front restaurants , land based tournament weigh in check in etc......have heard the same thing but if use responsibly wouldn’t worry about it to much if an emergency disaster situation

they would all have special land based radio licences.

Yes, In order to transmit on marine VHF frequencies, from a shore base station, all those mentioned have, or legally must have, a special shore base station FCC license , only available to specific providers of approved marine uses. I believe there is now a limited exception for use of a <10W H/H marine VHF unit to communicate briefly from nearside shore to main vessel.

13.8V is nominal voltage, you should be good to go with any 12V battery.

i have 2 of these in my garage, super useful, light, small form factor, easy to charge, small charger https://www.cabelas.com/product/Cabe...ery/700551.uts

Why is it illegal to use it on land?
