Its interesting that we are just now having people get the Bel RX65 with the newer hardware and FCC ID of QL4G7M4.
Bel filed that ID with FCC just over a year ago, and no one has been able to get their hands on one until the past couple of months.
Bel says there will be no difference in performance, but I bet there will be.
I guess this means that we won't see the new X50 hardware with FCC ID QKLX5M4 for another year. :?
