UV5R for Satellite Communications

[Lightspeed]

Hi RS

Yes, it is possible, and it certainly extends the range of UHF communications

I wouldn't rely on the satelites being open access after a TU event though

Also, even if they do remain active they are in range for a fairly short period and transmitters and receivers have to be constantly frequency adjusted to compensate for the dopler effect introduced by the satelites velocity. This makes working another person via satelite a fairly technical undertaking.

For info, using UV5r/3r radios it is possible to communicate with the International Space Station. Their orbit is many hundreds of Km above the earth, but the transmission remains line of sight while the ISS is over the horizon so comms are possible using low power.

It certainly raises some interesting possibilities.

Lightspeed - any comments?
