13.8 volt, 100 watt linear

[rogbarrier]

Does anyone make a 13.8 volt linear for vhf marine radios.Thanks

Yes, there are commercial Class C amplifiers usually designed for FM operation in the 150-174 mHz business/public service band. TPL manufactures some for mobile use. General Electric has some models designed for 100% duty cycle (constant carrier).

I thought there was a 35 or 50 watt limit on Marine channels.

 

[Big_Ears]

You are correct. I believe the maximum is 25 watts, RF output. Makes no sense to extend your transmit range unless the other vessel is capable of transmiting the same amount. Or perhaps the intention is for emergencies only. In that case, a commercially manufactured ELT beacon would be a better choice.

many moons ago, I built a patrol boat, 92 Boston Whaler w/ VHF 100 watt spectra on normal channels, VHF 100Watt spectra w/ marine channels, 800 MHz spectra on the trunked system, and UHF spectra for interops.
Let's put this way, law enforcement patrol boat, didn't see the worry about reaching out from the middle of Lake Erie.
Then came the MPSCS system. One radio does all. Including interops with CG. Still, the VHF marine spectra stays.

The Spectra is not Type Accepted for Part 80 (Marine Service) use.
