The first acquisition was a Regency Digital Flight Scan receiver. It has a wooden case and is a bit large. I got it home and, after a bit of work to find a motorola to bnc adapter, found that it receives ATC transmissions great. I have found that modern broadband scanners have a hard time hearing ATC even though they are supposed to be such great receivers. Filtering the FM broadcast band helps, but they are poor performers. It's nice to be able to have a dedicated ATC receiver.
The next find was a Uniden BC200XLT scanner. The original owner had no use for it since it didn't do trunking. I was excited to buy it. After adding a discriminator tap and mounting a jack in the housing (an advantage of having older larger scanners - there's more room to mount an audio jack), it's up and running as an additional analog scanner and discriminator source.
