I was lucky to tour the NSS facility before the towers came down but  
after the facility disassembly was started.  The lowest frequency they  
operated at was 20.4 Kc.  The main tower was some 1200 feet tall with  
a surrounding ring of 800 foot towers and wires that went horizontally  
to a trio of similar very old triangular towers (which were not taken  
down).  For more info, see:

The purpose of this VLF station was to alert our submarines to listen  
on other frequencies for additional information (presumably very  
important).  Cutler Maine, and perhaps  a couple of other transmitting  
stations may still operate at that frequency,

NSS operated at other higher frequencies also, but I am not familiar  
with those transmitters.
