[Dxbase] Prefix mappings

[Greg - N4CC]

Hi Ed -- The mappings you see are for callsigns used by Gus Browning on his
worldwide expeditions in the 60's to Bhutan.  Some of the OT's can show you QSL
cards from those expeditions...when hearing those calls truly meant exotic DX
was being heard!  I never worked Gus at any of those locations -- didn't have
the antenna system that would have been required at the time...In the 60's that
stuff was super "rare"...  73 de Greg-N4CC
