Do you have the programming cable and software such as
FreeSCAN? If so, I can make you a file with the Jefferson County trunk system and area conventional frequencies programmed, no hiring necessary.
Almost all talkgroups on the Jefferson County trunk system are P25 digital, however, so you won't be able to hear them with your BCT-15. Only a few of the smaller fire departments on the system are analog. The good news is most of the fire departments using P25 on the system simulcast their traffic on VHF and UHF analog frequencies. There is also a few that still use VHF/UHF primarily.
In the meantime, you may find this
easier to read manual helpful.
