Man, when they talk "low power," they're not kidding. My handheld ham rig is around the same volume as the LPT, including battery, and it puts out 1W or 3.5W of head-microwaving fun. If I read the docs here right, they're talking about 115mW. But then, my handheld doesn't handle data encoding, DSP for consumer electronics didn't exist yet when it was built, and it CERTAINLY can't listen to 32 separate receiver channels while broadcating on four separate transmit channels! <img src="/images/icons/smile.gif" /><br /><br />The Alinco DJ-C5T handheld radio is 3.42 cubic inches, 3oz, and in addition to pumping out 300mW on two different bands, it has a mosquito repeller. Three of these, special ordered to cover whatever radio band we need instead of the 2m/70cm ham bands, would be smaller than the current LPT and handle our needs, though it would have fewer features -- the onboard computer would be responsible for all the data encrypting and encoding.<br /><br />I've only skimmed the document, but it seems to me that the LPT or MiniT would have to be special ordered for the GX3 anyhow, unless we want it to use TDRSS.<br /><br />I volunteer to set up Ground Station Vancouver, if Mr. Bigelow will buy me some land on a suburban mountaintop.
