New prefix for Pitcairn: The new prefix for Pitcairn Island in the South
Pacific is VP6. The British possession changed its call sign prefix from VR6
to VP6 on May 1 (1998). Call sign suffixes will remain the same. As part of
the reversion of Hong Kong to China, the British government also ceded the
international ITU prefix block, VRA-VRZ, to China. Old timers may recall
that VP6 used to belong to Barbadoes before it became independent.

Does anyone know off hand what year the prefix for
Pitcairn Island changed from VR6 to VP6? Or, for
that matter, where can I find general reference material
for questions of this sort. (eg. old dx callbooks).

Thanks,
