[HamWAN PSDR] "r2" Version Supports all Three Band Widths - MikroTik QRT 5ac 5GHz outdoor flat panel 24dBi antenna

[Nigel Vander Houwen]

Don, you are correct, both of which matter, but historically the issue with the AC models has been not supporting the 5/10mhz channels we use.

Of course the international version is still required to tune to the Part 97 frequencies.

Below is the response from MikroTik Support confirming that the new version of the QRT 5 ac also supports 5 and 10 MHz band widths because of a new chipset in the "r2" revision.  Just need to make sure you don't get the old version.
