There has been a strong carrier on 137.7446 kHz for at least a week. No
modulation and strength doesn't seem to vary.
Can anyone else hear this ?
Yes, I can. It is so consistant (ever since we were allocated the
band) that I use it as frequency check marker when using Spectran or
Gram. It is clearly audible so I use it to check my receiver/antenna
system on audio CW as well. I understand that the signal originates
in France but I can't remember where I got this information.
