A similar one one about 138.250 khz.  Very close to a loran 
line.  The one on 137.877 khz runs for about 8 seconds then 
drops in strength about 10 db for another 8 seconds.  Time 
between transmission is about 24 seconds.  I asked about 
these years ago but don't think we ever came to a conclusion 
about their origin.

Hi Dex,
Thanks for the info. Interesting you can hear it also in NC. This is the 
first time I noticed the one on 137.877 since about a week ago. It is quite strong 
here in SC. The one on 138.250 is a constant carrier but it also shifts in 
power level - it sounds like higher power for about 17 seconds then lower power 
for about 22 seconds. 
 
I think I have heard the one on 138.250 before but just dismissed it as a 
carrier of some sort. The one on 137.877 is new and noticeably close to the band, 
at least for someone with a wider filter in their receiver.
 
The one on 137.877 might be an interesting target signal for the guys up in 
the NE. Wonder if anyone up there can hear it?
