Notes, Description by user AlienScientist:
Very Interesting Information (found in: The European Table of Frequency Allocations and Utilisation (pdf) (page 39):
Look at the "Notes"
Frequency Major Utilization Notes
=========================
14350 - 14990 kHz Defence systems
Wireless applications Active animal implantable devices
in Healthcare within the band 12500-20000 kHz
I also found a site (for the US) "unwantedemission.com
where I entered "14749 KHz". It will show what they are used for...try it.
Now, something interesting in the UK data. It says "UK11: ...for low power devices exempt from licensing..."....Low Power Devices (such as implants?). When you also look below, notice who the "Major User" is.
It also states inside the documents: "The UK Frequency Allocation Table, until recently a classified document"!!! There is a list of documents you can click on or download the zip file (link below).
