Largest was 200KW (AN/FRT-72). At USS Annapolis AGMR-1 48 transmitters, none smaller than 1KW (AN/URT-23). Largest was 40KW (AN/FRT-40). At NAVRADSTA(T) Driver 55 transmitters none smaller than 10KW (AN/FRT-39B). Largest was 600KW (AN/FRT-100).

"Jim Hampton" wrote Just out of curiosity, do you have an idea of how much power the Navy uses on the VLF stuff? I don't know current QRO, but in the 70's the COMSUBLANT transmitter at Cutler was 1,700,000W on 15.9KHz and the COMSUBPAC transmitter at Jim Creek was 2,200,000W on 17.1KHz. The ELF site at Clam Lake is reportedly engineered for just under 1,000,000,000W at somewhere just above powerline QRG, 75Hz if I remember correctly. The antenna is just under 29 miles long. 73, de Hans, K0HB |

But compare it to other technologies.... 2.2 million watts is only 2200 kW. At 746 W per HP, that works out to just under 2,950 HP. You could get more than that out of a single 1950s era diesel electric railroad locomotive, or a WW2 bomber - or about a dozen SUVs. Compared to the power of even a "small" USN ship or submarine... The 1 gigawatt ELF system is a bit bigger, of course. Count the cars on the Genessee Expressway where it crosses Jefferson Road at rush hour and see how quickly you get to the million-horsepower mark... 73 de Jim, N2EY |
