I actually DID work on one of those VHF Radars, as very young tech.
It was at a Military Museum, and I replaced the Dynamotor that suppiled
the HV for the Transmitter. I got the Dynamotor from a unit that was
"Scrapped in Place" half way up the Mountain at Alitak, Alaska on the
southern tip of Kodiak Island. It was installed during WWII, to do
Sea Search for the Japanese Navy approching Kodiak Island. I was able to
lug the Dynamotor, down off the mountain, on one of my trips to the top,
to service a Remote Base Marine VHF site I had installed at the summit.
It is amazing how far 25 Watts of VHF will go when the Antenna is at
3500 Ft. That Site was designed to work a Tropo Path, 235 Miles long,
to an associated Salmon Processor at Chignik, Alaska. Really worked
good most of the summer, untill a weather front would come thru and
dissrupt the Temprature Inversion Layer between the two locations.
Then it would go out, and it took a couple of days, to rebuild the
Inversion Layer, before the path would return. Now days, it is all
done by SatPhones, and Cellular. Oh well, MF/HF is just about DEAD,
as well, in the Maritime Community. Good thing I am reTIRED.....
