Its an XCVR2450, but I do *not* start any 'packet'

listen for packets.
In which case, the TX side is running--even if you aren't sending
any *data* bits, it's still transmitting, and blocking the receiver.
You'll have to get more sophisticated about half-duplex flow
management, using tagging to tell UHD to turn on/off the TX side.
Josh probably has better words of wisdom on this than I.

XCVR2450 db and you continuously transmit you sort of block
receiver indeed. That's because the XCVR2450 is only
