The oldest Police Call I still have is 1981, which is about when I bought my first programmable scanner.
Up until that time, everything I had was crystal controlled, and the Radio Shack folks were good at knowing what you needed.....They kept the local frequencies stocked.......If you needed a rock for another part of the city, you simply drove to a Radio Shack store in the part of town you wanted to hear.
It sounds crazy now, but that's how it was done.....
Any oddball crystals had to be special ordered.
Along with my collection of Police Call books, is a "Fox Scanner Radio Listings" book for the Kansas City area, which included listings for businesses, utilities, etc.
Fox made a few scanners, but were probably better known for their radar detectors.
Although I never bought one, there used to be a "Betty Bearcat" frequency directory as well.
Back to the original subject........Police Call also had a "Beyond Police Call" directory that covered the entire country.....Copyright on this one is 1994.
These sold out pretty fast when they first came out, and I had to drive around town to several Radio Shack stores to find one. This was a pretty common ritual with the annual Police Call directories as well.
Stores didn't want to get stuck with a big inventory of outdated books at the end of the year, so they simply quit restocking them at a certain point.
The contents are pretty much self explanatory from the pic.
