GB3DA 2m FM Voice Repeater
GB3DA is the primary 2 metre FM voice repeater for Essex.
Based at Danbury Hill near Chelmsford, its central location makes it ideal for general coverage of the county.
Units DA-1 and DA-2 use Mk2 CUL logic, whilst DA-4 is based on a Yaesu Fusion repeater. The antenna system is fed via a 6-cavity diplexer from Procom/Telewave, plus a DCI filter on the receiver side.

DA-4 installed on 8-Dec-2019 uses a Yaesu DR2-XE System Fusion box inc its internal controller. Normally set for C4FM or FM input, and FM out.
Compared to our older units, Idents etc sound different and there is no 'K' ack - please wait for the short Tx squelch tail instead

An Upgrade to DA-3 using ADI radios (similar to ER-3) was suspended
