We had seven turn up at times between 09:30 and 17:00. Graham completed the sequencer install for control of the 40m T98 transmitter. Martyn ran the AM net while Harry and Luke worked on balun construction. Luke brought muffins for morning tea :-). On air measurements made by Harry and Keith ZL1BQE showed the 5557 repeater was under modulating compared to the received signal ( 1 khz deviation on RX was retransmitted at 0.8kHz deviation ). The TX deviation was increased. Feedback on comparative audio levels / quality from the repeater is welcome. The IR illuminator for the East wall camera was reinstalled, and progress made on corrosion control for the exterior lamp cages.
