I have used this company's 900 MHz products (115.2 kbps) with great
success. There are less expensive equivalent alternatives available, but
these are reliable and meet their own specifications. I see they are now
advertising 1.3 GHz products for "military", but presume they would have
no qualms about selling them. You'll have to request a price quote.
The 900 MHz stuff is reasonable, but not cheap. Don't know about the
1.3 GHz stuff.

Thanks.

These appear to be in the ISM (licence free) band -not high speed amateur
packet radios - and are limited in their power output. In Australia at
900MHz our limit is 1W ERP.

I priced the 900MHz ones from the Australian disributer and they were $1600
for the serial version or $2800 for the ethernet version.

I wonder how much they are in the US?
