8.4 Frequency Reference Chart
Table 16 lists the transmit frequencies assigned to UK private fixed telemetry
and telecontrol radio services (as of the manual publication date). Group A fre-
quencies are those normally assigned to stations operating in this service.
Group B frequencies are “interleave” channels that are offset from the Group
A frequencies by 6.25 kHz. The assignment of interleave channels is consid-
ered on a case-by-case basis.
Users are responsible to ensure that their operation is on authorised frequencies
as stated by the station licence. Inquiries on UK regulatory compliance should
be directed to:
