The cooling fan unit for the KOCU transmitter burned out sometime early the week of April 17. After a transmitter site visit by Chief Engineer John Roberts, the problem was diagnosed as a cooling fan failure.
Thanks to the listeners in Altus for alerting us to the problem.
The electronics in modern transmitters shut the transmitter down if the cooling fan goes out. This prohibits damage to the actual transmitter itself.
After arriving in Altus, John and his helper, Director Doug Cole got to the process of repairing the transmitter.
