[ARC5] Related Question Maybe - Re: 4-course radio ranges

[hwhall at compuserve.com]

1630 appears to have been used for marine comm even back into the 1930s, at least along the Canada Pacific coast. Some of the same stations were still listed in a 1964 update that I found.- Radio Aids To Navigation 1939, H.O. PUb. No. 205, Vol II- US Naval Oceanographic Office, Corrections To Radio Aids, H.O. Pub. No. 117B, 23 May 1964
A 1934 Senate congressional record noted that frequencies 1530-1630 kc - were allocated to Moblie A1, A2, A3.
A Canadian publication "Flight Comment" for Jan-Feb, 1971, mentioned an event where one Otter airplane on the ground transmitted on 1630 kc as a beacon to help another Otter make a landing through ground fog.

Google still hasn't turned up anything specific to normal aviation use, though.

Boat radios are drastically being thinned out, but you sometimes saw them even in the Seattle area with one channel on 1630 kcs.  I recall hearing Bull Harbor BC with wx broadcasts on 1630. You could easily hear it in Seattle in winter even on a car radio. -Hue Miller______________________________________________________________
