Freaks -

I've found what could be a great deal on ebay: someone selling about 50 Motorola RF modems for $20 each. You can see the details (or lack thereof) if you follow this link. I'm hoping someone out there knows something about these. Could two of them be used to create a bidirectional wireless communication setup? I'm not finding too much useful information on Google.... If you have any solid info, please post, I would be greatful!

Not without a license, you won't be able to use any transmitter with a wattage that high.

Writing code is like having sex.... make one little mistake, and you're supporting it for life.

I have a licence but ...

The 800Mhz band id not free here in DK , and prob not in the EU

So i cant use it too :?

But then again , 35w is going to make a "Nice microwawe oven" , if used inside.

And unless you have a friend on the "plains" i the middle of nowhere (and and antenna with a line of sight) , you wouldnt need those.

There might be an ISM band somewhere round 800MHz that would be licence free. But usually there is a power limit to 1W (EIRP) in these bands. Hi power attenuator might be usefull in dropping the EIRP and I'd say the radio itself could be turned down also.

Cheers,
Steve

For the US anyway, there are "license free" segments scattered all over the spectrum
with various antenna and power limitations. FCC Part 15 has more info.
