Probably JT65 digital mode.  Most use 14.076 + offset.

Thanks for the info...

Have heard the 5 letter groupings around 6700 khz in the evenings here and always wondered what their origin was.

Another excellent article.  It's always interesting to study how the propagation changes, especially around the times the band goes long at night, and then comes back in the morning.  I've been trying to do something similar here using the signal strength plotting functions in Spectrum Lab.  Another idea I'm trying is to break the plots up into 24hr blocks and then average the readings over several days to try and smooth things out and get a general idea of propagation, though the variation in solar flux, etc. might change conditions a bit from day to day.  Thanks again for the propagation plots...

HF Beacons / Re: 30 meter dasher, or ???

Could this possibly be hams experimenting with the new OPERA digital mode?  I know it uses a pseudo-CW type signal and is designed for weak signal beaconing, similar to WSPR.  Most activity seems to be around 10135-136.
