       Engineering information provided by Joel "J. R." Miller, Bob McClanathan and others.  Here is a look at the transmitter and tower facilities from the earliest days when there was just a hole in the ground.  We will add more as we can dig up the photos.  Be sure to check out The Studios page.

If you look closely, you can see KQIV's AEL FM-25KD transmitter (Ser. No. 008) sitting on a pallet inside the unfinished building.

J.R. Miller remembers:  It was a big day. Saturday, August 12, 1972. After several weeks of installation work, KQIV's consulting engineer Bob McClanathan was ready to test the transmitter. Manufacturers' representative Tom Aye flew in from Sunnyvale, California, and Don Richardson, AEL Transmitter Division Manager, arrived from Lansdale, Pennsylvania, for the event. Bob had borrowed a 25KW air-cooled dummy load for the test, but it immediately failed upon application of power. Now what?

Bob had an idea. He knew that Portland's KPAM-FM had a water-cooled dummy load that would handle the job, but there wasn't adequate running water available at the transmitter site. So, he assigned me the detail of finding a water tanker while he headed into Portland to see if he could borrow KPAM-FM's dummy load.
Now, where do you find a tank truck full of water late on a Saturday afternoon? After thinking on it a few moments, I drove to downtown Oregon City with a possible source in mind. After explaining my dilemma to the nice firefighters at the Clackamas County Fire District station, I was relieved when they said they'd be happy to help, and would be up in just a little while. Bob got back with the dummy load and its hoses were connected to the tanker. As the cool waters flowed, the transmitter tests were completed successfully. KQIV now was ready to attach the real antenna and hit the airwaves.
