When I went off to college in the 80's with my trusty BC100XLT, I found no traffic on the University frequencies listed in Police Call. After asking around, someone said they heard the university was on 800MHz. No way, I thought. NO ONE was up that high. After confirming it with FCC data, I found that they were early adopters of an 800MHz Moto trunked system. I had no idea what a trunked system was about, but I set out to find a way to listen. There was a Regency handheld and a bit later the 800XLT base scanner, but they were very expensive. I saw the GRE Super Converter advertised in Pop Comm, and ordered it. I think it was around $100. I programmed in all the freqs in UHF by subtracting 400MHz into my 100XLT, and it worked like a charm. I had to hit the scan button if the repeater dropped before the other person responded, but fortunately the system wasn't super busy. Good memories with that little box.
