The ieee80211_radiotap man page from FreeBSD states that:
This field contains a single unsigned 8-bit value that is the data rate. Legacy
rates are in units of 500Kbps. MCS rates (used on 802.11n/HT channels) have the
high bit set and the MCS in the low 7 bits.

So, I believe that in this case the data rate of 0x82 is correctly interpreted
as MSC2 => 19.5 Mbps

I think that the fact that 0x82 * 0.5 Mbps = 65 Mbps is a strange coincidence.
Maybe the rate is erroneously reported as legacy rate?
