If, like my store, they are cloning from one scanner to another, there probably was or is an associate that is a "scanner buff" that put together a list of frequencies for the surrounding area. Ours is not an all inclusive list by any means, but just a couple of hundred frequencies and a couple of trunked systems with talkgroups covering Police, Fire, EMS, Local Gov., Business/Press, Railroad, Aircraft, Amatuer Radio, and such. This was just to give the customer "something" to listen to and a general idea of what was out there until they could get their feet wet in the hobby, as it were. The stores usually have Scancat-Lite loaded on one of the cashlane computers and they can pull frequency lists as .RSD files off of the NAT-COM website, but those lists are not nearly as useful as something someone with an interest in the hobby can put together in a few minutes. I even had requests from other stores to put together lists for them for different radios that the Shack sells for their particular area. I would usually export it out of a Starrsoft program as a comma delimited text file and then import it into Scancat-Lite to save it as an .RSD file for them.
