Now that the antenna switch matrix switches are in position, work has begun to connect them to each other. Instead of using wires, 1-1/2" copper tubing is used for the RF interconnections. It will take hundreds of feet of tubing and several days of work to form all of the connections between the ten switches. It is a good thing that all three of the guys shown in the photo have plenty of plumbing experience.
TX1 and TX2 were the first transmitters installed at KTWR. They were put on the air in 1977. They each have over 120,000 hours of broadcast time on them. Lately, we had been using them as back-ups for the other three transmitters at the station. It was determined that it was time to sell them. A radio ministry in the States now owns them. They have been disassembled, packed, and containerized for the trip overseas.
It definitely looks, sounds, and feels different in the transmitter hall now. We hope that demand for Christian radio programming will increase to the point that we will need a fourth transmitter in the future. We have a nice empty place in the room to put it.
