Once you exit UniTrunker, it will save several files. One for the frequencies (HZ), one for the talkgroups (GID), etc. The one for the frequencies will be labeled Motoxxxx.hz (xxxx = the system ID), for instance one of the systems I monitor here is Moto2808.hz. I'd open that file using Notepad or Wordpad and then put the frequencies in it. Below is the HZ file off of the 2808 system.
Columns:
1 - Site
2 - LCN
3 - Control Channel
4 - Listen
5 - Lockout
6 - Frequency
7 - CTCSS
8 - DCS
9 - Label
10 - First date seen by UniTrunker
11 - Last date seen by UniTrunker
12 - Confirmed
13 - Hits
14 - Notes
So the edit the frequency, I'd look on my UniTrunker screen and look at the red number. In your case it would be "2BD". Then I'd look at my scanner and see what frequency is displayed. Then open the HZ file and look for the row with 2BD in it. Count over 6 columns (after the 5th comma) and place the frequency there. It must be 9 characters long with NO decimal. Then save the hz file and reopen UniTrunker. Instead of "2BD" being displayed, it'll display the frequency. You can edit the other files to add names of channels, sites, etc as well.
