[CQ-Contest] UN1ZZZ/A?

[Hank Greeb]

Anyone work UN1ZZZ/A besides me during the recent UN DX World Wide 
Contest?  (Kazakhstan)?

Post contest I looked up the call on QRZ.com, NIL there.  He was spotted 
by the RBN a few times as UN1ZZZ (no /A) over the weekend, but not very 
active.

A few other stations from Kazakhstan were sporting the /A after their calls.

I wondered if it were a "cut number" for /1, but why would a UN1 be 
operating portable?

Any help would be appreciated.
