Two issues for your consideration.

First, CFH, Halifax is also on 137 kHz and you might want to see if you can
copy this station on the West Coast.  They are quite loud on the east coast.

Second, there is a RTTY signal on 135.95, 50 Hz FSK, which seems to come
from the West Coast according to the times it is heard here - is it also off
the air?  This station has been given to me as NPG from the West Coast.
