hi all, earlier I reported I had purchased one of the new models of high-sensitivity GPS receivers. they are supposed to work indoors, as well as much quicker and better outdoors. well, it did sort of, but it was a usb interface, and it only worked well with the software from the same manufacturer (Delorme); not with my application. they had a generic driver, but it didn't work well. it was a standard 12 channel design, and was only $40, so I wasn't too upset. Then, I found an even better one; it used bluetooth, had 66 channels, and the same high-sensitivity. I just received it, plugged it into my pc, and it just worked!!! it's now talking to my pc, via bluetooth, in the house, and it's giving me my position within 3 meters, and it only took a few seconds from a cold start! and, it was only around $75. And, if you have something that doesn't have bluetooth, it also has a usb interface, and a better windows driver for usb than my old one! It's an I-blue 747a and I got it from Amazon if anyone else is interested. it's also about the size of a deck of cards, maybe smaller! it does not output serial information, and so if your device requires that, and can't run a windows driver (like some older ones do), then I guess this wouldn't work. otherwise, this is well worth investigating. Anyone who likes is welcome to borrow this and try it. And of course, Amazon has a great returns policy. hth, Chip Check out the TABI resource web page at http://acorange.home.comcast.net/TABI and please make suggestions for new material. if you'd like to unsubscribe you can do so through the freelists.org web interface, or by sending an email to the address tabi-request@xxxxxxxxxxxxx with the word "unsubscribe" in the subject.
