This is a great question!
I started out as a kid around 10 years old with a Pro-94 from radio shack. I remember back in the late 90s and early 00s, I was able to listen to...quite a bit that would be taboo and unethical by today's standards (remember the cordless house phone era?). Besides typical Fire and Police, Listening to FRS and GMRS, and Ham was the norm for a nosey kid. I believe the Pro94 was released in April of 2000 and I had one shortly afterwards for a while. I wish I could find it.
I remember looking at Radio and Scanning magazines and wanting sooo bad the Bearcat 780XLT, to me that was the top dog scanner, and it could scan UHF AIR bands. After 9/11 I remember UHF Air being pulled from alot of other scanners. My Pro94 could not and that was a big thing I wanted since I lived in Pensacola and there was a lot of military air activity going on at the time, and I loved airplanes, still do.
Since then Ive gotten a Uniden SDS-200, which is wayyyy cooler than the 780XLT (which I would still like to own..).
