As of Sunday 2nd December 2012, the 1750Hz toneburst access mode on the 2m repeater GB3BF has been disabled and the receiver is now fully protected.

You must use 77Hz CTCSS tone to access or use GB3BF, “plain” carriers are no longer relayed.

This change is to help reject signals from people working other repeaters.

GB3BL is not affected by this change.
