So, who else here had a Uniden Bearcat BC-760XLT back in the day? I actually bought two of these, one for the house and one for the car and added the optional CTCSS decoder. Unfortunately, I had nothing at the time to easily search for CTCSS codes! So, I started by using two of the 20 channel banks and programming in the various combinations of tones on a frequency that I was trying to figure out. Tedious, but effective. I fairly quickly started to notice patterns. For example, the county I was living in used a common tone for police and fire. Neighboring counties usually used a common tone for their police and fire. That led to me becoming interested in learning more about sub-audible signalling. I was a bit confused, at first, when I would hear what I later found out were "community repeaters" with multiple, disparate users sharing. I couldn't always find a PL tone for them. It was sometime later that I found out that they were often using DPL! It would be quite some time later until I had equipment to search for PL AND DPLs!
When I finally got a radio that would search for sub-audible signals and log them under computer control, it was a lot of fun to determine who the users were, what frequencies and PL/DPL they were using, etc.
In it's day, the Uniden BC-895XLT would display the CTCSS in use pretty quickly. It still had no DPL, though. Does anybody remember which Uniden was the first to use DPL? Was it the Uniden BC796D?
