[Hallicrafters] SX-88/GPR92

[Peter Markavage]

GPR-90 military version was R-825/URR and 90RX was the R-840/URR. Don't
recall ever seeing a military designation for the GPR-92.

And for Glen in his message:
"out of "upstate" New York"
TMC was located just outside of NYC in a town called Mamaroneck (not very
upstate) and in Canada.

As Meir pointed out there is no similarity in circuitry to the SX-88 and
also in performance. Unlike the 90's, I believe the 92 was designed with
SSB and ISB as it's primary "mode" focus for use in diversity
applications.

Never really liked the performance of the 90. On AM, selectivity was
either too much or too little and nothing in between.
