Stewart,

Also, is the following about the FSK signals correct?
On about 73.6 kHz is CFH (75 Hz shift and 75 BPS)
and on about 73.3 kHz is Rugby (100 Hz shift and 100 BPS).

I have only seen listings in The Lowdown for CFH being on 73.6. They
certainly haven't been there in the last week, as the signal would be
overpowering here in Massachusetts.

The center frequency for Rugby is 73.25 as seen here, and the signal is
exactly 100 Hz wide. It is a few dB stronger here tonight than it was at
this UTC time on Tuesday.
