[Premium-Rx] Diveresity Operation

[Richard M. MC Clung]

In the early to mid 70's I was the Section Chief for a Radio Section in
the Army. We had R-390A's and AN/GSH-17 Coder-Burst Recording devices.
I built up the switching arangement and the audio combiner from Capt.
Lee's article for two diversity positions. They worked extremely well
for the intercept positions. And they wee great for copying AFRTS
(remember them?) on SW....... I'd like to build one or two to use with
my R-390A's but I can't find the data on the transformers so I can find
some substitutes. Yes it could be solidstated but I want to make the
tube version for my tube radios.
