Adıyaman Ulubaba UHF repeater now in service
There is good news for emergency communications: the new UHF repeater that TRAC installed on Ulubaba Tepe in Adıyaman has entered service. The repeater was licensed by the TRAC Şanlıurfa Branch, and the branch also carried out the technical work.
In brief, the technical side is this: the repeater sits at the summit of Ulubaba Tepe at 2,500 metres, operating on 439.3125 MHz with a 77.0 Hz CTCSS tone. It is powered entirely by solar energy and is designed to provide uninterrupted service. On remote hilltops I think this is the most sensible solution, since there are few other ways to keep a repeater running on a summit with no mains electricity.
In the first field tests the repeater could be reached from parts of Adıyaman, Gaziantep, Şanlıurfa, Diyarbakır and Kahramanmaraş. Communication was also achieved around Osmaniye and Hatay (Antakya), and good results were reported towards Malatya and Elazığ. TRAC says it will continue to monitor performance and that shortcomings and improvements will be addressed in the coming period.
There is also the bigger picture. The Ulubaba repeater is planned to work in tandem with the repeater on Karagöl Tepe, one of the highest peaks in the Black Sea region at 3,107 metres, and with the 145.600 repeater, which can be reached from more than 20 cities. In this way coverage extends across different regions, aiming for continuous communication during emergencies.
Many volunteers contributed to the project, above all TRAC Adıyaman Representative Cengiz Gümüş (TA8CNG), TRAC Şanlıurfa Branch board member Mustafa Özbakır (TA8MOZ), Efe Özçağlar (TA2ZU), who provided technical support for the installation, and Hüseyin Odabaş (TA1DF). Thank you all. Seeing volunteer-driven infrastructure work like this reminds me why amateur radio still matters.
