Know What You Need B4 You Can Decide What You Want
Rule number one for buying a radio - know what you want to do with it, and make sure what you buy will do what you want.
The Pro-92 (HH) and Pro-2067 (base/mobile) are Radio Shack scanners made by GRE that do Motorola, EDACS and LTR trunking, and have alpha tags. They also have PL controlled squelch (like CTCSS receive mode on a Ham radio) and the fastest PL search I have ever seen. Discontinued by RS, but still commonly available on the used market.
The later RS scanners made by GRE (the 93, 95, and 96) do NOT do LTR trunking.
I don't know about Unidens, but others on this group can help there.
It's kind of like the digital argument. At my regular RS, the sales person tried to sell me a -96. I said, "Why, there's no digital here that requires it. I'd be paying an extra $350 for features I can't use". She had no idea what I was talking about.
So I explained to her (the manager at this store) that Tulsa only has one digital talkgroup, and it's the EMSA (encrypted) and that the best deal on their shelf was the $150 (on sale) Pro-95 - with the drawback to it being that it won't trunk LTR (around here, most notably used by Storey Wrecker).
So she asked how to monitor them, and I pulled my 5 year old -95 off my belt.
