[Hallicrafters] SX-88/GPR92

[Lee Bahr]

The SX-88 was made and designed by Hallicrafters.  Technical Material
Corporation (TMC) designed and built the GPR-92.  TMC was owned by Ray
DePasquale.  Of course, Hallicrafters was owned by Bill Halligan, until
Northrup bought it in the mid 60s.  The TMC receivers look a lot like
Hammarlund receivers.  I understand the reason for this is TMC design
engineers came from Hammarlund. Both are double conversion receivers.

list but I am happy to be back.
> The reason for this post is that tomorrow I will receive a TMC GPR-92
radio. This is even rarer than the SX-88 I think. Anyway I have reason to
believe that the GPR-92 may be a militarized version of the SX-88. I wonder
if anyone knows anything about this? Does anyone know where I can get an
SX-88 schematic to compare? Fortunately the GPR-92 comes with a manual.

on such a rare bird. Unfortunately it does not belong to me but was
discovered recently by a friend.
