I don't know what broadcasts from those towers on prune hill in Camas but there is a sign for a proposed development right next to them...

Who owns those towers and what exactly do they do? It's probably a stupid question but I don't know much about radio towers and such.

If I remember right, KNRK has a stick somewhere around there, and I think KGON has a gap filler on the water tank, targeting east Vancouver........

(I could be wrong, tho.)

No, KNRK never broadcast from Prune Hill. They began as KMUZ-FM on Mt. Scott. In 1991 the proposed Prune Hill site was for then C.P. KWQM 94.7MHz at 3308 McKever Rd., which is 150 feet east of the Upper Prune Hill Water Reservoir.

The Clark County 911 System also has a microwave tower up on Prune Hill, one of 6 simulcast radio towers in the Clark County Emergency Services system. I also believe Portland 911 also has a presence there, as I've seen their utility trucks within the compound.

I looked at options from Prune Hill in 1989 for my 105.9 application. It's not a great site for several reasons. I went with Livingston Mtn ... further away but much higher up. That's where Channel 2 originally broadcast from when they were short spaced with Ch. 3 in Bend.

Ch. 3 started as KVDO in Salem, then a few years after OPB bought it, the transmitter was moved to Bend.

Andy, you're scaring me!

>>KVDO in Salem

there are some disturbing elements of the history of the station from a weirdo cutting down the tower and later found dead in the Willamette River after serving time for the deed to Eugene television orchestrating the move to Bend to the loss of the only VHF signal for Oregon's capital city...old-timers can pipe in here now...

KVDO had no place to go. They had to protect channel 2 IN SALEM!

Originally KATU channel 2 had to protect channel 3, which wasn't even on the air.

Ya, thats what the Transmitter ENGR for Ch 2 told me once when I was about 16 years old. They were on Livingston originally due to CH 3 which hadnt even been turned on in 1960 yet ??!!!

Now the part of that story I have never heard, or dont remember if I ever did, was how KATU got to have a Tower on Sylvan finally with Ch 3 just down the valley?? Might have been that Ch 3 was offset, Ch 2 offset and perhaps directional with a null towards Salem and Ch 3 low power and also directional... ??

If memory serves, it was a waiver rooted in $$.

KATU wasn't even located at the top of the mountain where the AT&T microwave tower has been since the early 50's. They were just down from the top on a short tower where the batwings were so low you could practically jump up and swing from the lowest one. I wasn't there, but I've seen pictures. The 40 x 60 prefab building they were in is identical to the one in Sylvan. They sold it and the buyer converted it to a house.

Andy, which tower on Livingston are you on?

I've got a transmitter and receiver for our 2Way paging network on the Motorola, I mean Pinnacle, I mean Global Signal tower!

The AT&T tower is now managed/owned by American Tower and I've actually considered relocating my equipment to it.

Let me know the next time you are going up there. I can always "arrange" to do a PM on my equipment!
