I would like to know if after updating the firmware to the latest version on these scanners, do you still need to use custom bandplans, or will the scanner automatically set the correct one? I am using Win500 to program from the RR database. Also the main System I am wondering about is the TACN Tennessee system. I have two pro 197s and have programmed one with 800mhz standard and the other with the 800mhz rebanded table, and I notice no difference. Thanks, Gary.
