[ARC5] Mystery Black Box

[D C _Mac_ Macdonald]

With the current coward in chief, everything that diminishes the US military capability is considered to be good! Look at all the nuclear subs and carriers all parked in a row, waiting for a Pearl Harbor style attack!

> shows that LORAN C was developed during the 1942 to 1958 period with the first operational system fielded in 1957.  With its date of 1955, my mystery box may have been meant for converting the experimental LORAN C signals for reception on the APN-4.  The connectors match those on the APN-4. I suspect the Distant/Local switch refers to skywave/groundwave.
> I did not know that LORAN C was operational that early or that the APN-9 could receive both LORAN A and C.  LORAN A has long been gone, and apparently Pres. Obama killed LORAN C in favor of GPS.  So now, what's the backup? Omega? Transit?
