Thanks to Hue K7HUE for saving these very interesting magazines covering late war and early post-war Navy electronics. I have scanned and posted all the issues 7/45-5/52 (1.25 GB) at
Much of the coverage focuses on radar, but there is a pretty fair amount on communications equipment and topics. Plenty of interesting reading and info.
The combined index is just the individual volume indexes in order, so when you find a topic, check which volume index you are in. And search to the end of the combined index because articles of interest may be scattered in different volumes.
Cheers,
