We're always looking for more good shots! Submissions of material are appreciated.

This page will change, as different pictures are received. 

This first set is some general pictures, courtesy of Dave Driessen:

Raytheon KTR100 TV portable microwave. 6 or 13GHz. Output power 100milliwatts. They claim a range of 25 miles. The manual was printed in 1956. Check out the cars in the background!

Equipment mounted in racks. Must have been very pleasant in there in the summer. I recognize the unit on the right as an RCA BW5 tv sideband response analyzer used to broadband TV transmitters. We had one and the tracking generator. We wished we had had a spectrum analyzer then!

 

Many stations would install the microwave equipment on the ground and bounce it off a reflector on the tower. The FCC doesn't allow this any more...

 

An ITT Radar Videx Receiver
We never actually used this (we got it used or free somewhere) A pair of phone lines would connect it to your local weather service radar.

RCA TVM1 TV microwave. 6GHZ 1Watt
. We actually used it a couple of times. The equipment shown weighs well over 200 pounds not including the big camera cable used to connect the transmitter head to the control unit.

 

Part of the transmitter showing the klystron.

An important note about this resource:

We have used many sources, including FCC files, university lecturers, historical publications and more, and have tried to be as accurate as possible, not repeating many of the myths of the industry (such as the Uncle Don Story) nor histories "manufactured" by promotion departments. However, I am not perfect, and may well have overlooked something. If you do see an error or omission, please let me know.
