Keith is planning on rotating the transponders we have, starting next year. I believe he mentioned bringing 4 transponders each week; new starters/members will be given priority.
Not an ideal situation for all, but the batteries are starting to fail in some and the manufacturer is no longer offering to service or replace them. Therefore we need to make what we have last.
By the same reasoning, personal transponders will be required for the national series from 2011 - see
here.
