I won't give all the details of how to get to Red Top, etc. This summit has been well covered by others. Here is an interesting report from K7MAS for comparison:
Easy Trail
Noise floor....You mean noise ceiling.
Summary: On 28MAR19 I decided to knock out the first activation on Field Effect Hill (aka Megler Mountain). The weather started out beautiful and sunny but I ended up having to complete my activation in the rain which contiuned until I had started the hike back down when the sun returned. Overall, the hike isnt bad but the the horrible wide band RFI in the vincinity of the summit made this less fun for an HF activation than most summits which tend to be far quieter.
First activation of Benson Point
After abortive failures earlier in the day due to lack of access I finally completed an activation on this awesome summit on a beautiful day.
Access to the summit is via gated logging roads with recreation use permitted signs and no motor vehicles allowed.
Parking is directly off Highway 47 south of Clatskanie at position: 46.041460, -123.248066
There is ample parking for multiple vehicles as seen below:
875 Doppler Shift Hill First Activation
I completed the first activation on Doppler Shift on 04MAR2019. The hike is roughly 2 miles from a logging gate. In my case this gate was open however as with all these gates they can be closed and locked at any time so pass them at your own risk. I was able to drive about 3/4 of the way up before finding a 'Unauthorized Motor Vehicle Access Prohibited' sign. At that point I found a spot to park and hiked the rest of the way to the activation point.
Cooper Mountain, OR | Feb 2019
The activation zone for Cooper Mountain is a (very) short hike above the dog park at Winkelman Park, 10139 SW 175th Ave, Beaverton, Oregon. There is no AZ access from Cooper Mountain Nature Park to the west and the summit proper is posted "No Trespassing."
Clear Lake Butte, OR - snowshoe | Feb 2019
Here's a long snowshoe in winter - 7 miles round trip and 800 feet elevation gain. The lookout is rented in the winter, so be sure no one is there if you climb up the stairs to take advantage of the additional height.
W7O/CE-278, 5580 - 1701m, 4 Points 1st Activation November 2018
"5580" is a four-point summit approximately 25 miles northeast of Prineville, OR. It is fairly easy to reach by roads with a short pack to the summit. The summit was activated for the 1st time on 24-Nov-2018 by Roland - K7FOP and myself Shelby -N7SHG.
Hat Point, OR | June 2017
In the remote corner of the remote corner of Northeast Oregon are the Wallowa Mountains. On the eastern edge of the state, looking down into the Snake River Canyon is Hat Point, a drive-up six-point summit.
Head east on 350 from Joseph, Oregon 30 miles to Imnaha. From there, you'll take Hat Point Road another 10 miles to the lookout and summit of Hat Point. This gravel road is steep in places, and narrow, but can be driven in a passenger car.
Fall Mountain, OR | July 2017
Here's a drive-up summit with a fire lookout (one you can rent) in Eastern Oregon. You might spring for a lookout reservation and enjoy being chased all day long - but you can also stay below te lookout on the road and let the occupants enjoy their solitude while you activate this peak.
Lake Butte, OR | June 2017
Here's an easy road walk in Eastern Oregon of about 2.1 miles round trip and 400 feet of gain. Interestingly, there's only one "Lake Butte" in Oregon - and there's no lake near it.
