Nothing on earlier this afternoon…that will be 3 new FM’s in the Valley in a month if they get on.September 20, 2017 at 9:41 pm #31912Radio RuminatorParticipant
KPWI’s signal doesn’t really cover Salem. I think there would be too much interference from KWAX for KPWI to be heard in Salem.September 20, 2017 at 10:55 pm #31913
Could not KPWI co-locate with KSXM’s site for better Salem coverage?September 20, 2017 at 11:01 pm #31914
91.1 can’t move south. KWAX co channel 69 miles distance required.September 22, 2017 at 11:01 am #31923
No KPWI as of this morning…strong KWAX still…in SalemAugust 29, 2018 at 10:34 am #39127Craig_AdamsParticipant

Antenna would have to be in Keizer—north…August 29, 2018 at 3:25 pm #39136
Actually, they have filed to be silent. They can only move 6 km. That puts them short of Keizer or Salem proper. They knew going in that they weren’t going to reach Salem from as far away as they are. They need to be careful because of the terrain. Some of the areas to the SE of their site are blocked by higher hills and if they move there they still won’t get into much of Salem. They would be better off moving where they have line of sight to where they want to cover, either SSE or ESE, the former better for covering Salem the latter for covering Keizer. On a short tower, higher terrain nearby will kill coverage.August 29, 2018 at 8:41 pm #39143
West Salem Water tower??? South southeast…

That move would be way too far, 8.77 km. Also, even if they could move that far, it is far from ideal because:
1. The hill on top of which the City Of Salem Emergency Communications Tower (Crestview Dr. S. & Downs St. S.) sits would throw a huge shadow into much of Salem since it is higher by about 200 feet in elevation (minus the HAG of your proposed antenna on the water tower.
2. Metal water towers make horrible antenna sites for a multitude of reasons. I always recommend against that choice.August 29, 2018 at 11:05 pm #39149Randy_in_EugeneParticipant
Hmmm, that doesn’t seem very far from the KWAX translator licensed to Turner. (Can’t get FCC maps to show.) Isn’t there a rule about not interfering with the input of an existing translator?August 30, 2018 at 11:37 am #39156cbaravelliSpectator
“2. Metal water towers make horrible antenna sites for a multitude of reasons. I always recommend against that choice.”
Um … water towers are excellent “towers”. We do all the time in cellular. Main problem is the city or water district. Just be sure to use a mast.
KWPI-LP is silent since Saturday. Good ears.
Appears more aggressive than not.August 30, 2018 at 1:33 pm #39170Alfredo_TParticipant
In another thread, Andy stated that water towers are suitable for mounting UHF antennas, but he does not recommend their use for VHF installations. His explanation is that at VHF, the metal supporting structure has to be hot dipped to avoid intermodulation issues (presumably from metal-metal joints that become rectifying when they corrode).
I wonder, are there many six and two meter amateur repeaters on water towers, or have hams discovered intermodulation problems the hard way?August 30, 2018 at 1:47 pm #39171cbaravelliSpectator
I’ll wait for Mister Brown to comment.
