The ARRL's DXCC desk says that A52JR is valid for DXCC; there is no "documentation issue".
Thanks for doing that Dave...
There was a comment in the current OPDX Bulletin, probably didn't help matters:
The Ohio/Penn Dx PacketCluster
DX Bulletin No. 1177
August 25, 2014
"A52JR QSLs are being rejected for DXCC due to lack of documentation", states, Steve, K6UM.
It would be nice if everyone understood the difference between LoTW credit and DXCC credit for award purposes.
Two different programs with different rules, requirements and procedures for accreditation.
LoTW only appears once in the current DXCC Rules, in a general way.
