This is, without,question, the single most important item of communications equipment you should have at your retreat. It should be the first piece of radio gear you acquire. I would rather hear what is being over the all the airwaves around my site, than have the most up-to-date, high-speed, low-drag transceivers. The radio watch in your BDOC should always be monitoring the scanners, 24/7. And a big thanks should go out Sparks for finding this item for a great price. I’m a sucker for anything ICOM, their equipment is first-rate. I would attach an extended, matched antenna, hung as high as possible, to increase the range.
Another important use, as Sparks implies in his post and indicates on his frequency list, are known surveillance device transmitting frequencies. You can use the scanner as a poor man’s sweep. This ties with Sam Culper’s article on GPS beacons and other tracing devices.
