Paul,
It's almost certainly CFH. It's been quite a while since they burned off
the cobwebs on their 137 kHz setup. Was almost wondering if they gave up
on the frequency. If they start modulating, I'd keep out of a +/-300 Hz
BW around 137 kHz.
Typically, they'll goof around for a couple of weeks and go away.

For several hours there has been a very strong carrier on 137.000

It has been there today for at least 8 hours, maybe longer as I
don't know when it started. I'm not sure if this could be CFH
testing, or ???
During the day this signal is very consistent within +/- 0.5 dB at
my station.
