[Lowfer] 55.5 kHz & 57.4 kHz

[Garry Hess]

If you fly Google Earth to the coordinates 63 51 1.31 N, 22 28 0.38 W 
you see what appears to be two separate transmitter sites. The eastern 
one is smaller than the western one and possibly the source of 57.4 kHz, 
while the other may be for 37.5 kHz. Like David mentioned, I have 
occasionally seen only 57.4 kHz active, and vice versa.
