The UK 1.3 GHz or 23cms allocation runs from 1240 to 1325 MHz with the centre of the narrow band operating segment at 1296.100 MHz. The 1300-1325 MHz section is unique to the UK and used by a number of ATV repeater outputs.

Band Plan

See the RSGB 1.3GHz band plan for full details.

Beacons

There are a number of narrow band beacons in the 1.3 GHz band - see this page for an up to date list. There are also a number of licensed voice repeaters in the band which provide useful off air narrowband ID signals

Voice/Data

The UK has a series of FM Voice repeaters and as well as some 23cm D-Star DV/DD systems. ETCC

ATV

The 23cm band accommodates significant ATV activity. FM-ATV is still popular but increasingly DATV is in use (based on DVB-S QPSK). See the BATC website and Wiki for further info.

1.3 GHz Equipment

23cms is a great band to get an introduction to microwaves and several equipment manufacturers make transverters for 1.3GHz:
