[Amps] 10dB and propagation

G4FTC worte:

"HAARP was orginally conceived to generate ELF signals - if I recall 
correctly for communications with
submarines while submerged."

"and it only requires a relatively small amount of power (but in the MW 
range) to effectively modulate the electrojet."

*******So it's the modulation of the electrojet that allows the military to 
communicate with submarines while submerged?
