> Greetings to the list. It is many years since I have participated in this
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.
> I am excited about this as one does not often get an opportunity to work
on such a rare bird. Unfortunately it does not belong to me but was
discovered recently by a friend.
