Looks like you simply use a wire or similar antenna near the transmitting antenna to pick up signal. Needs 100 mV out of the air. Also, to do it “off the air” rather than off the feedline, you need an additional unit priced at $199, so for Part 15, “off the air” monitoring, it’s about a $400 investment + you need a computer of course. Says you can also use a receiver, tapping into the i.f. But since I could also use this in my commercial work it might be worth checking out. There’s an interesting thread about these on a ham radio board I frequent:
I notice too that the page for the mod monitor also references the Hamilton Rangemaster with a link — for more about Part 15. So that’s a nice plug for the “industry” but makes me wonder if there’s any connection between Hamilton and Radio Associates — not that that’s bad by any means, but made me curious.
