J9ABO 1948 Okinawa, Ryukyus Islands
I am sure that this card was
used by the operator to confirm his contact when operating as
KR6AB.
He (Arthur M. Burton) was the op of both stations. Notice
"KR6AB" typed in the upper left-hand corner of the
card.
I have found no other amateur radio activity by him.
