Another band opening today:
Pagers and data signals from UK paging systems, European pager and data link and other telemetry systems. European "harmonized" paging band is apparently 26.2 MHz to 26.935 MHz (other sources say 26.225 MHz to 26.935 MHz or 26.2 MHz to 26.955 MHz) but numerous systems operate outside that range
