Logic

All of our repeaters use the G8CUL logic.

Access

Our repeaters must be opened either by use of a carrier modulated with a CTCSS tone of the frequency listed above or by use of a 1750Hz tone burst for between 200 and 400ms.


Once accessed, subsequent talk through can be by just a carrier although it is normal to continue to transmit CTCSS and more traditional to switch off the tone burst once the repeater has been opened.

Linking

On 4th November 2010, GB3CE and GB3CL were linked together via RF in a way as to be totally transparent to the users.  Anyone who accesses either repeater will be additionally relayed through the other one.  The originating repeater can be identified by the tone - If the signal originates on GB3CE then an ‘h’ will be sent in CW and if the signal originates on GB3CL then a ‘c’ will be sent.

Repeater upkeep

There is no official repeater group for our repeaters but if you would like to make a donation to the Martello Tower Group group to help fund the repeaters then we will be happy to accept it.


You can donate either via post to the repeater keeper:
