1296 MHz is under siege from the Galileo GPS system

Here is where I saw the first reports on QRZ.com a short while ago.

Threat to Amateur Radio 23cm band

A joint paper to be submitted to the CEPT CPG meeting in Ankara by France, Lithuania, Malta, Slovenia and The Netherlands attacks the continued use by Radio Amateurs of our 1240-1300 MHz band

This is the final CEPT CPG meeting in preparation for the ITU World Radiocommunication Conference 2019 (WRC-19) to be held in Sharm el-Sheikh, Egypt, October 28 to November 22. This conference will define the Agenda Items for WRC-23.
