Are similar units available for marine frequencies, with a minimum numer of hand controls? I'm of the impression that it is inefficient but not disastrous to use short aerials, if necessary with baluns, in low power transmitters. For example they are sometimes used in healthcare and for tracking animals. Peter Rattenbury and I recently demonstrated that transmitter power wasn't the issue with on water kayak communication using VHF. At least in our location it was cliffs getting in the way. Whether we used 1W or 5W didn't seem to matter. I think one of the reasons hand held HF radios are not available in recreational boating is because they are too complicated. Particularly with regard to appropriate frequency selection. But nowadays it should be possible to make HF radios more user friendly. All the best, PeterO *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
