basic stamp communication over radio
I'm trying to get two basic stamps (or one stamp and a computer) to
communicate via amateur radio. The stamp and the computer/other stamp will be about 10 miles apart. I want to use a basic stamp as a security device that will send data when told to do so by the other device. Can anyone point me in the right direction? I can explain further if needed.

Then connect the two Basic Stamps to the RS232 Ports on each TNC-2. What that gives you is a Bidirectional Serial Link between the two Basic Stamps.

... Get a couple of TNC-2's, one for each end and run them in Transparent That was kind of my knee-jerk reaction, but it's kind of the high priced approach. However, QST, this month or last, had a simple PIC-based APRS lashup. One could probably take that circuit, rip out the GPS software and replace it with something for dw's sensors on the remote end. One the PC end, the AGW packet engine makes a cheap TNC. Of course, thinking over it again ... if dw is spending all those dollars on Basic Stamps, then a couple of TNC's shouldn't be a big yank. ... |

TNC-2's are "cheaper than dirt on ebay. If the guy can't afford $25US, he should get out of the design biz....... Bruce in alaska -- add a 2 before @ |

Although a ham since 1967, I'm having my arm twisted to rustle up
something similar for (legal) data channels on licence free UHF CB radio. Here in NZ, & no doubt globally, these PRS/FRS ~470MHz 2 way radios are insanely cheap, ( US$30) yet have great range -managed an easy link across 6 miles of harbour with a pair. I'm calling the quest "KISS & tel" - for simple wireless telemetry - & will probably go for AFSK (Audio Freq Shift Keying). Instead of Basic Stamps,we'll be using the powerful PICAXE micros, since they've achieved near cult status downunder & are ~ 1/10th the same BS price.
