G'Day Keith, Michael and Michael,

Keith and Michael - Thanks for the information on 2m and 6m transceivers.
Unfortunately wavelengths below 10 meters are really in the VHF range and
starting to get problematic for long distance communication unless you use
exotic techniques or are lucky with solar flares.

Michael Neverdosky corrected me on my terminology, thanks, HF is what I mean
and preferably below 15Mhz. I don't think its necessary to go as far as
using Morse. What happened to SSB, frequency hopping, spread spectrum or
digital modulation methods? Why can't these technologies and the requisite
frequencies be made available to the broader community? Regarding aerials a
2 or 3 m extendable whip antenna with balun might be inefficient but should
still get more range than a VHF unit. I should think 1 to 10 miles would
satisfy most kayakers.

Flying a 22ft antennae on the end of a balloon or kite might be fun!

All the best, PeterO
