AM Stereo
AM Stereo is pretty cool (1450 KBPS here in Portland is still in stereo), but there were 5 proposed systems, one of which was very different and that developer was VERY vocal. The FCC evaluated them all, picked the Magnavox system, but the other developers cried foul and then the FCC said then “let the marketplace decide” which hamstrung AM stereo permanently. It never recovered, even after Motorola became the standard.
In 1982, the National Radio Broadcasters Association (NRBA) held a forum, and the document linked below is a summary.
Voices of Vanport
The town of Vanport, OR got washed away in a historic flood on May 30, 1948, but its legacy lives on, including the stories of several radio stations.
Here’s a piece from it about 620 KGW (now KPOJ):
"KGW’s Denver Avenue transmitter site was located at the farthest point from the breach in the railroad fill. So, when the fill broke through on May 30th, it took the flood waters nearly an hour to reach the station. After seeing the water approaching from a station window, transmitter operator Clyde Bruyn shut down KGW at 5:20 pm and made his way downstairs. By the time he was headed out of the site, water was swirling around the wheels of his car. After reaching higher ground, Mr. Bruyn stopped and watched the action. Flood waters were picking up and carrying along large chunks of debris. Soon an apartment building crashed into one of the 22’ pilings supporting the transmitter building. Then, at 5:51, a building struck one of the guy wires supporting the East Tower, causing it to crumple into the flood. KEX’s 300’ wooden tower went next. Eventually, only the top few feet of the transmitter building remained above the flood, with water waist deep in the equipment rooms. All of the transmitting equipment was destroyed and only the West Tower remained." Here's the link to the 2024 PDF:

Changes to the Portland TV “Dial”
On 7/28/20, all of us watching Portland TV off of the air with an antenna witnessed the beginning of the change to ATSC 3.0, Next Gen TV. By noon, some of the channels got rearranged and a couple disappeared RF-wise from the old ATSC 1.0 channel lineup.
Here’s the big picture:
