And, as I noted, there are RS232 interfaceable radiation detectors you can buy off the shelf -- no hardware hacking needed.
I was thinking about this the other day and wondered if it wouldn't be cheap and relatively easy to build a board that samples and sums several randomly selected signals on various frequencies on the AM broadcast spectrum.
Radio signals can be interfered with or listened to -- never underestimate the opponent. Computer interfaced radiation detectors, in spite of Tim's claim to the contrary, are pretty cheap and very hard to interfere with. Perry
