[Milsurplus] never @ a hamfest

Don't forget the Omega navigation system.  10+/- kHz.  The one on Oahu disappeared without a trace.  The antenna was easily visible miles away in Kaneohe.  It was there for one of my trips over, and gone the next.  Locals, hams and Navy Radio types alike, had no idea what was involved in removing that antenna which was strung between two mountain tops next to the Pali pass, nor what happened to the equipment.  Antenna insulators were purported to weigh around a ton each, and ther were several.  I never had time to locate a local Coast Guard radio person to get the true story.  I wanted the Cesium standards.

We were able to copy all the worldwide Omega signals in Texas on an amplified 10' monopole, using an HP 8566 spectrum analyzer.

Marty,  Jim Creek in Washington State used a VLF antenna
strung between two mountains.  It was the last VLF to go
except Sweden.. Marion, MA, was on 25.8 KHz running
RTTY.  I copied them in Alaska in 1957.  These frequencies
were so low that loops were the only thing that would work.
I undertand that even after WWII the British Post Office used
VLF for traffic to Europe.   I also know the Germans had
6-Meter systems all over middle Europe.
