Then my memory is somewhat fuzzy because I very vaguely recall reading an explanation on this site regarding why this tower needed insulators at the base. Unfortunately, I can’t recall why that was the case.January 28, 2020 at 2:10 pm #43920Andy BrownParticipant
The original tower for 97.1 sat upon mostly rocky soil. The AM service on 1410 was shunt fed to the tower, about 1/3 (maybe less) of the way up. It had horrible coverage because of the lack of ground plane. kb101’s photo belies the fact that the tower was immediately adjacent to the old studio building which appears to have already been demolished and the shunt feed removed. The RFI from 1410 inside the studio was so bad they built a Faraday cage around the control room to keep it out of the 97.1 program audio chain. The location is literally steps away from Stonehenge as you can see.
The original tower in the old KWJJ/KGON location was a phone pole. The xmtr building (This is down the road about 75 yards? from Stonehenge) started out it’s life in 1947 as the transmitter building for KPRA (later KWJJ-FM), Portland’s third FM station. The station was dark and the building abandoned by 1949. A wooden utility pole was used for the antenna. In the early 50’s experiments were undertaken at the building to determine if it was possible to receive signals from KING-TV, Seattle, for rebroadcast. Then a new self supporting four legged tower for KWJJ/KGON/etc. was erected. It wasn’t very tall (it was an old utility common carrier tower which they have since moved just down the road, from satellite you can see there are two four legged towers, pretty sure it was one of those, or maybe they scrapped it). If my memory serves the four legged tower was on the right of the building as shown in various photos. It was later replaced by the 300′ three legged tower (I think in the late 80’s). There were 6 stations on it. Originally, KGON was on one leg, KWJJ (KJIB) on another, KXL FM 95.5 on the third leg, KQFM (Z 100) on the fourth leg and KBOO and KPDQ were doubled up on two of the legs. When they replaced the four legged with the 3 legged, I don’t know the configuration.
The insulators were used so as not to screw up 1410’s pattern. They were probably used to allow detuning.
People to ask about this:
Gary Hilliard former chief 97.1/1410
Gray Haertig (lives on the site) radio consultant
Larry Wilson former chief of KXL (Don’t know if he’s still alive) not to be confused with the former CEO of Alpha)
Tom Rose former chief of KQFM (100.3)January 28, 2020 at 8:29 pm #43922e_dawgParticipant
You guys aren’t talking about the short fat triangle radio tower (4636 Council Crest Drive)that was torn down almost 15 years ago and 95.5 KXL-FM was the last tenant (100kw/302m)before they move to Healy Heights?

There were two separate towers next door to each other, the one for 1410/97.1 and the KXL-FM tower that held 90.7, 92.3, 93.7, 95.5(KXL), 99.5 and 100.3. 91.5/channel 10 was across the street. 101.1 was on the channel six tower and 101.9 was on the channel eight tower. 98.7/98.5 was on the 1330 tower on Mt. Scott and that was it! Everything else came later. (edit) When I wrote this, I didn’t realize that there another half page to read. Larry Wilson was my boss at KUPL in 1973-74. I sure was surprised to learn that KXL had two people with the same name, connected with them at the same time!

I noted today that a casualty of the departure of the Russian format from 1130 is the C-QUAM AM stereo. Now, KBPS is the only Portland area AM station that broadcasts in stereo.
