    Hello all, I've just been given a (Very nice) ship-to-shore radio transciever from a friend who scrapped his boat. It's a Kelvin Hughes Husun 65.

    Now, the problem is, I live about a mile from a major shiping port, so don't really want to meddle in shipping frequencies.

    So in short, what will I need to do to convert the reciever to CB frequency operation? Is it a case of changing a crystal or will major modifications be required?

    Probably not going to happen. :(

    Your radio is made for around 150 Mhz. CB is in the 30 Mhz. range.

    There is nothing in the marine radio that can be converted to CB. The Husan is FM modulated, CB is AM modulated (Huge difference). The Husan is in the VHF frequency range (150MHz), CB is in the 27 MHz range.

    This is how I would convert it to the CB band: sell it and buy a CB radio.

    It might be possible to convert it to the MURS (Multi-Use Radio Service) simply by changing crystals but it might not be legal to do so - not sure about the power limitations.

    Update time! Sold it to a friend's dad for his boat.
