I was reading in a separate thread that soon to be released UHD code

Thanks,

With that particular radio, yes.
That was for the B2xx series and E3xx series, which are based on the
AD9361/AD9364 chips, which were never really designed for
fast frequency-hopping applications.
The other RF cards, like WBX, SBX, CBX have faster PLL synthesizers, so
faster hopping is possible, although there are host-to-radio
transaction times to consider as well.
