ERG - Repeater Logic
The original logic for GB3DA and GB3ER was based on the original G3RKL/GB3US variety. By the early 1990s its condition was poor and CTCSS amongst other facilities was required. The original units were replaced in 1995 with units developed by Malcolm G3XVV. During the 1996/7 site relocation, this was repackaged and enhanced. Eventually the XVV Logic was also retired and donated to the Braintree GB3BZ 70cms Repeater Project in 2001
A third Mk2 CUL board was acquired in the autumn of 1998 and was pressed into service during 1999 to act as a spare and to assist development work.
To support the newer GB3DB 6m and GB3ZP 23cms systems, two newer enhanced Mk3 CUL units were acquired. Overall we now have five CUL logic units, of which two units are kept in reserve. Separately, our DStar repeater GB7ZP uses an Icom ID-RP2C Logic controller.
