This morning while one the way to work I monitored BMR techs on TG 0016 discussing the weekends problems, at one point one of the techs mentioned he was called in on the weekend to fix a problem in Pembroke. He mentioned he fixed the problem by switching from Transmitter A to Transmitter B. Interesting thing is I was only able to monitor one side of the conversation. I was monitoring of the Kinburn tower at the time.
