My first was the Uniden BC210XLT which was more than capable enough during the pre-2000 years for my county and neighboring areas. As things changed I went to the BC780XLT, which again, filled the need as trunking started to come into vogue in my area. But of course things continued to change and I wound up with digital scanners on the desk and in the vehicle. I also had a Pro-43 which I modded to receive the then analog cell system, which provided some entertainment.
I went through various Radio Shack models over the years such as (in no particular order) the aforementioned Pro-43, 83, 92, 95, 96, 97, 106, 163, 651, 668, 2035, 2042, 2045, 2055, 2067 and 2096. The Unidens I've owned (again no particular order) include the aforementioned BC210XLT, BCT15, BCD396XT, BC780XLT, BC898T, BCD996XT, BCD996P2 and now I am at the SDS200 as my sole owned scanner, which sits in my Ram pickup full time.
I went through a period where I had no scanners after I sold off everything, as I regained interest in what was my first hobby as a kid - astronomy. That is still my primary interest, but after some time away from RR, I came back to look around and started reading about what was going on now, and became interested in the SDS200 since there is a lot of simulcast around us here. I have and will always be interested in monitoring the PD and FD/Rescue services. I've tried other things like school busses, businesses, utilities, etc., but for myself I've found them quite boring. We all like what we like of course.
However, with the increasing level of encryption in use for PD, it has been more challenging. Plus my home county now uses CAD and there is really no voice transmissions in the public safety realm any longer, so I eschew monitoring them for my surrounding areas that at least use traditional dispatching methods. So I am more selective about the systems I monitor while out in my truck, particularly going between our other property in western Virginia where I do the majority of my astronomical observing because of the much darker skies. There are still some departments out there not using encryption which always provides me with entertainment as I drive around town, or going to and from the other place. Anyway, there is where I've been and where I am with the hobby.
