I have had my eye on a Xagyl product for about a year.  It is capable of HSMM in our 70 cm band.

That has seemed to have been stalled due to the fact their are not sure of the size of the market.

Recently I have been in contact with the manufacture, Doodle Labs and am buying a pair in the upcoming weeks.

You can expect to read more after I have a pair.

It may be too late to start using 440MHz. The government is contemplating selling off the frequencies to help fund the 700MHz public safety spectrum. Here's a few links:

• ARRL action plan
• HR 607 pdf

You may recall that there's a company called ReconRobotics that has some small robots which can be thrown into an area and then can moved around remotely to provide video. IIRC, they and ARRL are already in a tussle over the 70cm band.

Looks like these robots are already being used in the Austin area: Williamson County and Leander.

Kinda makes me wonder who ReconRobotics paid off to get the 70cm band on the docket for a future auction.

So, buy your 440MHz mPCI cards now, because soon you may not be able to.

If the 70cm band follows the 1.25m band, I wonder what other ham bands will soon follow? 3.3GHz? 10GHz?

Well I did my part and wrote my representatives.

After a bunch of discussion, Doodle Labs mentioned they planned on releasing a model that specifically covers the ham spectrum. (see below)

They are still trying on getting a distributor lined up, and will be in touch with me and others who have contacted them as soon as that is done.
