So a friend gave me his Pro-668 and i read that the software is within the memory card. I installed it into my computer, and read through the "Easier To Read" for the pro 668/1080/etc but i simply do not get how to put in frequencies into the scanner. I just want to put in the P25 systems of my area (Alameda County Frequencies in the Bay Area such as Alameda County Sheriff's, Oakland PD, Livermore PD, pretty much all P25 systems surrounding my city) Can anyone help with some steps on how to input these frequencies? maybe some tips or suggestions on how to work the software, i really don't want to mess things up before trying to even tweak anything.
