3.4 GHz DATV

In 2014/5 the UK 9cm amateur band was reduced to 3400-3410 MHz (from 3475 MHz), along with restrictions in 13cm. Consequently it only has the room to run DATV. However these spectrum changes have prompted development work and the band has proofed useful for UK repeater outputs.

Reports from the repeaters on 3.4 GHz suggests it is very low noise spectrum and actually performs as well if not better than 2.3 GHz.

There is (or was) a lot of surplus transmit (and receive) equipment on the surplus market, mainly from the failed Ionica broadband wireless system, and it is a very easy band to get on to, both for Tx and Rx.
