How many here worked with the Old Loran-C Timing System that preceded GPS?

For providing the Timing for Electronics it did an excellent job for me for years.

My first ship, USS Claud Jones ( DE-1033 ), had a WPN-5 installed ( Submarine variant ). The XO sent me to a month-long tech school at Ford Island because our unit consistently provided locations half way around the world. After exhaustively testing every circuit I could not find any fault. Then the OPS boss assigned me the lovely task of verifying the entire ship's installed/portable electronic equipment. This entailed verifying nameplate and serial number designations of everything. The last item on my list was the LORAN antenna coupler which was at the extreme end of the yardarm. As I compared the serial numbers I noticed that only an 18" length of cable protruded from the coupler as it curved under the yardarm. Next to it was a bare ended cable coming up the mast. Turned out that the yardbirds who originally installed had never mated the two cables resulting in garbled crosstalk between them which threw off all the timing. Never heard squat from the 20 or so CT's aboard about that.

Oh Bloody Hell, The Yardbirds really did hose that up. I can't imagine how the CTs got anything beside basic Radio Intercept done. No way you could do DF without that Timing.

As a non-rate, I learned on Loran, but we got GPS before I left the Cutter.

I don't miss taking the Timing Differential readings on the Loran-C at Sugar Grove, WV.
