Well, I guess Im close to High Heaven. Bald Peak/Mountain Top is behind where I live, but signals off of High Heaven come in much clearer. I know that both Bald Peak and High Heaven are repeaters for Yamhill County, does OSP have repeaters up on either of those?
OSP Channel 14 156.225 is on High Heaven
OSP Channel 18 156.225 is on Chehalem Mtn above Newberg
one of OSP Channel 21's 155.910 transmitters is also on Chehalem Mtn above Newberg
i.e. in Portland, you listen to 154.935, but there are many inputs to that output frequency,
ch. 9, 10, 11 and 12...
Close.
Single output frequency, single input frequency -
But multiple PL tones to manually choose a repeater. Except...
Salem cars (155.91) use only 1 transmit PL for multiple repeater sites.
They use voting receivers to steer which transmitter is used.
A mobile does not have to choose a repeater (channel). It's automatic.
Bend, Roseburg, The Dalles and probably other areas work this way, too.
I think Astoria as well, but am unsure.
Why all district/area repeaters aren't configured this way is unknown.
I have the same problem in Salem but on 154.860, I hear OSP Northern Commannd Dispatch fine but cars up in the Cascade Foothills in Linn and Marion Co. come in broken or not at all.
I've been up Hwy 22 East of Stayton to Detroit and beyond
and both the cars and dispatcher are loud and clear on 154.86 156.7
The most eastern repeaters up there are just not designed to cover all the way down to Salem.
What you're probably hearing, as an example, is a car choosing the Hall's Ridge repeater above Detroit,
and the Dispatcher answering him on the repeater at Green Peter Reservoir above Sweet Home.
You hear the dispatcher fine in Salem, but the car is scratchy to you from the repeater in Detroit.
The car in Detroit is still in range of the Sweet Home repeater and everybody sounds fine to the
dispatcher via microwave links.
A similar situation may be happening to Gezelle007
who may be shielded from hearing the dispatcher using
Buxton Lookout in far north Washington County to answer all mobiles
no matter which repeater they're using.
Hope this boatload of info makes sense.
