The GB3DT repeater has been upgraded to a Yaesu System Fusion repeater (DR-1X) to replace the MOULD system that was previously in operation. This has been initially purchased by Joe (2E0OEM), Alex (M1LXM) and Rich (G0ZEP) with the hope that the long suffering noise problem from being ‘secondary users’ on the tower, would be significantly reduced.
At the same time as upgrading the repeater, a battery backup was installed to enable the repeater to continue to operate should the mains power fluctuate or be disrupted. This is provided by a 13.5V, 35A mains powered power supply connected in parallel with the repeater and a 12V 65AH AGM Battery. This has been tested and will keep the repeater operating for at least 12 hours without mains power. Following the upgrade, the existing filters were also adjusted to reduce CTCSS noise from weak signals but further work may be carried out over the coming few weeks as required.
Initial reports have been very positive following the upgrade and the repeater team would be grateful of any feedback over the air or by e-mail.
