Wow -- there's a lot of space in those bands.
135.7 kHz = 2,210.76 meters
137.8 kHz = 2,177.07 meters
Available bandwidth in wavelength is 33.69 meters!

472 kHz = 635.59 meters
479 kHz=626.3 meters
Available bandwidth is 9.29 meters!

Have a nice day :-)
(Actually what this probably means is that the circuits will have to be 
tuned for specific operating frequencies within each of these ranges).
