Hi Berkeman,
Judging by your signature, you might be able to shed some light. The experiment is on www.altair.org[/URL] and the guy seems to be a HAM enthusiast. I sent him an email asking for a starting point.[/QUOTE]
I didn't get much in a quick skim of the link that cristo posted for altair, but I went to the ARRL.org website (the main HAM radio organization), and did a search on Gunnplexer. I got some great hits, but the best ones were in the ARRL members-only area, so I can't post links to them here. :blushing:
But I cut out the "Resources and Links" section from the best article (I'm pretty sure it's okay for me to do that), and I'll post that here to get you some good pointers. Looks to be interesting stuff. I couldn't tell from a quick read if you need a HAM license to transmit on the X-band that keeps getting mentioned for these Gunnplexer transceivers, but I'm sure that's covered in the links below. Feel free to PM me if you have HAM related questions.
