Just received a BC796D, which needs to be reprogrammed for this area. This is my first trunking scanner. Not sure which programming software to purchase (ARC, ProScan, ScanControl??), but cannot program radio until I get a proper serial/USB converter cable. Can I purchase and upload software to my computer today (take advantage of sales?) and then program the radio at later time when I get the cable, or does the radio have to be cabled to the computer during software upload from the publisher. Also, any recommendations as to the serial/USB converter?
