THE LATTER YEARS OF OBAN RADIO/GNE
In the 1970's the UK Coast Radio Stations were re-equipped to meet the requirements of the introduction of SSB radiotelephony in the maritime world. Oban's first SSB transmitter, a 1kW Marconi H1000 transmitter with multi-frequency drive unit and broadband amplifier, was installed alongside the old AM/CW transmitters. Later the old AM/CW transmitters were replaced with Ajax 1Kw single frequency SSB transmitters with the H1000 moving into a back-up roll. GNE had five Ajax transmitters, one for each of it's main frequencies - 2182 (distress and calling), 1792 (answering UK ships), 2740 (broadcasting and main working), 1848 (second working - shared with North Foreland) and 1612kHz (trawler-band WT).
The operating consols were also replaced with the introduction of Eddystone EC958 receivers and updated transmitter control equipment. Even the colour scheme changed, out went the old GPO grey and in came cream, a colour considered more pleasant to the working environment!
