I tested 2 identical setups, same distance (18 miles) with same towers, only the radio was different. Older M5 models operate with 30MHz channel width and 228MB, while AC radios only operate with 10MHz channel width and 50 to 60MB. I expected more from newer technology. It annoys me, newer and less functional. Save your M5s, you'll need them for the long jump.
