"I think it went 24 hours when it was still KVAN and changed to KARO which would have been in the late 70s

KVAN built the directional array in 1976-77. McClanathan was fired. I was promoted to Chief and retuned the array and phasor under the direction of Jim Kemman from Silliman, Moffet and Kowalski (soon to become ERI).
Kemman was a physics guy. He did the Empire State Bldg Master Antenna (the one before 9/11). Then Kowalski came out and we did the full proof of performance (I remember having to drive with my head out the window as Kowalski was a chain smoker). Got zapped in the nuts by electric fences several times walking to his "exact" spots to get a reading. Anyway, KVAN began 24 hour broadcasting November 11, 1977 from the array which was located in Orchards near 164th and 34th. They also relocated the studio to a new building at the Orchards transmitter site where we all helped hook up a two studio set up with a big live performance room that never happened. This turned the old swamp location on N. Portland Road into a 1 kW daytime only site which had to be manned since we didn't have a remote control.
There was a deep null aimed right at Redding. The night license was 5kW DA so there were a lot of areas 7 to 20 miles out that could get a great signal at night, much better than the day, but anyone in the SW null (there were four nulls) had to be really close to not get KRED interference. On Marine Dr. the null was barely a blip. By the time you got to NE Glisan, the null was about 8 - 10 blocks wide. By SE Division, it was 15 blocks or more. The SW and NW nulls were deeper than the SE and NE nulls. The SW null had to deal with co-chaneel KRED, the NW null at first adjacent Kelso, the NE null to Dakota or Montana (don't remember, could have even been eastern WA) and the SE null was just a result of creating the pattern with enough forward gain to put 5mV into enough of Vancouver to pass the requirement. At that time, KVAN was one of only two stations running more night power than day power.
The first 24 hour lineup was:
6AM to 10PM - Les Friedman (News Director)
10AM to 3PM - Paul Mitchell (Music Director)
3PM to 7PM - Bob "The Big B.A." Ancheta (PD)
7PM to 12AM - Jay Nordlund aka "Lee Abrahms"
12AM to 6AM - Andy Brown (Chief Engineer)
