That frequency is in the 30 meter amateur radio band, which is only Morse Code and digital signals--no voice comms. So perhaps it was Morse Code? But, perhaps not--there are a lot of strange signals that stray into the ham bands.
If you want to hear more ham Morse, try listening around 7025 at night, and 14025 and 21025 during the day. By tuning up and down about 20 kcs, you should hear more ham Morse Code, which can vary from about 5wpm up to 30wpm. Software and standalone-gadgets are available to decode the stronger, clear signals. (Not many folks want to bother learning to copy Morse Code by ear these days... even most new hams.)
