Does anyone know what mode the following frequency is? I hear digital signal on it - like a jackhammer sound.

Hi Jon,

Is there any chance you could post a recording, just a short clip?

Would not be the first time someone programmed up a DMR/P25 radio on the wrong frequencies.

Tried (installed an audio recorder plug-in to SDR#) and found the bursts were quite short and spaced quite a long time apart. Decided to just watch the SDR# waterfall for a bit. Pretty sure it was from a close frequency. There was a very strong (very wide) signal next to this frequency and that may have blown through the front-end of the RTL-SDR dongle. I will continue to monitor but not holding my breath... smile.
