I am fully aware of that, thank you. My point was that with an EDACS system, you simply need to enter the new frequencies (not necessarily always 15 MHz lower, although that is generally the case). The issue with Motorola systems is that they rely on FCC channel #'s, which are coded into the scanner's firmware. If that firmware is not able to be updated with the new channel #'s, the scanner is unable to properly track the Motorola TRS.EDACS systems *are* impacted by rebanding; but you don't need to have a firmware fix or custom table for them. Just reprogram the frequencies by reducing them by 15 mhz and keep the LCN in mind. The Oakland/Piedmont EDACS system is a case in point. It's not flagged in the database because no special tables are needed to track it.
