Here's a neat clearinghouse for our hobby, and a good,
growing alternative to internet auction sites. We now use them
to sell most of our radio-related stuff.
VRPS is Vintage Radio &
Phonograph Society in the Dallas area. My very first exposure
to antique radios, and a place we try to return to every year
or so - we live on the west coast now. Lots of things year round,
but of special note is their annual convention November in Mesquite
and annual spring auction in Mid-March.
