Is it from your own computer?

Computers throw trash all over the spectrum ::)

Peace!

Probably JT65 digital mode.  Most use 14.076 + offset.

Note 14078 is within the part of the amateur radio 20-meter band used for digital modes. You will find all sorts of digi modes between 14065 and 14095. I would suspect anything unusual in that part of the spectrum to be an amateur radio digital mode of some sort before I'd think of anything else.
