Look for one of the "fox and hound" hobby groups. They have small transmitters
that they hide and have other members track them down'. I think these things operate on Childrens Band but they may be on some other "license free" frequency. |

Less legally, and hopefully well offshore, you might be able to get away with a floating VHF hand held set to low power and an unused channel. On your boat you would need a directional VHF receiver. There are also special frequencies and equipment intended for animal tracking that you might be able to adapt. Most off shore fisherman use a floating fiberglass whip (like a mooring pickup stick) with a flag and small radar reflector on the top. You should be able to buy these ready made from any commercial fisheries supplier. |

JET Find youself a good radio shop (not so easy these days ![]() I would avoid any emergency channels. A transmitter, with or without blinking LED, should not be a problem. Legally, standard FM frequencies are out. If you're running drugs, make sure that you use a standard Coast Guard frequency. It will save time and tax dollars. ![]() noah Courtesy of Lee Yeaton, See the boats of rec.boats www.TheBayGuide.com/rec.boats |
