FM Bandscan at Round Mountain, near White Pass WA (elevation 5,970ft) 7/30/21

My first Cascades hike of the season (well, I did Manastash Lake again earlier in the month and had close to 10 mosquito bites that time!) But this is a new spot for me, Round Mountain, W of Clear Lake, and SE of White Pass near US-12. The elevation was 5,970 feet, and I could see the Goat Rocks, Mt. Adams, Rimrock Lake, Clear Lake, and a variety of mountains to the north (including Shellrock Peak at 6800+ feet which I hiked up last August!) Pics coming later, but I saw two pikas (not pictured), multiple chipmunks and squirrels, two vultures flying around, a small Western fence lizard, and *fresh* bear scat about 3/4ths up the mountain. I kept my eyes peeled, but no bear sightings today. Thank God! Not to mention a multitude of butterflies, and horseflies/bees/house flies that were annoying me at the summit while I was eating lunch!

Apologies for not researching your posts to know. You mention nulls and to the east etc. did you use a directional antenna such as a Yagi or Log Periodic? Also did you have a clear shot to the horizon in all directions? I mean were you blocked by a close-in ridge or largely clear except for peaks miles away? I'm sure park rangers know the drill, but did other hikers look at you funny?
 
There were NO OTHER hikers at this mountain. On a Friday afternoon with everyone heading for Rimrock and Clear Lake to camp out, this was a surprise. I was all alone, no worries about people. The next day wouldn't have mattered because yesterday (Saturday), the sky was foggy, hazy, and smoky, with worse visibility. I lucked out being there Friday afternoon.
Nulls, 'to the east', etc - there were points on the trail where the west was blocked as I was climbing towards the end of the trail. East horizon was open. All I had was my ATS-909X and the telescopic whip. The summit is quite roomy, so certain points I could point it one way and have Vancouver, and another way and have Olympia. Of course I didn't keep the radio on from the lowest point to the highest point, I just pulled it out and scanned at a few spots along the way, then again at the summit while eating lunch.
The clearest shot to the horizon seemed to be E to SE, and a little bit to the NW surprisingly, as Rainier should be in the way. These Vancouver signals were over 200 miles away and some of them came in at incredible levels for a portable. But that's what 5,970 feet elevation does in the Pacific NW.
 
But that's what 5,970 feet elevation does in the Pacific NW.
At my transmitter site for HCTM1, 95.1 in Quito around 1968, I had one occasion where I had a moment after doing transmitter work but before sunrise where I could check out the FM dial on my car radio. The site was at a bit over 4000 meters AMSL, and the zig-zag road up could not be safely driven in the dark.

Looking at the same location on a map today, it says the elevation is 15,696 feet.

It was a couple of hours after sunrise in Lima, Perú and I got FM 100 at around 750 miles. I was entertained, and listened a while. At that point, I scanned the dial and found an FM from San José, Costa Rica coming in nicely at 800 miles.

At that point, I had finished by container of coffee and eaten my entire food supply that I brought from the prior afternoon drive up and was getting sleepy and cold, so I drove back down to the city.

At the time, Quito only had two reasonably powered FMs and one of them was not on the air until noon, so just my main FM was operating. Quito also had 3 FMs used as STL's, and the were 1000 meters lower and directional away from where I was. Ecuador had no other FMs at the time. Colombia, to the north, had many FM STLs, but they were 10 to 15 watts with yagis pointed at AM transmitter sites, and I never heard any of those on repeated tries from the mountaintop. But the Lima and San José stations were often heard; each of those was the first commercial FM in its country, too.
 
From the looks of things, it seems like Rainier was perhaps blocking the Bellingham Class Cs but not Vancouver. Might have been partially blocking Victoria as well.
 
Keep in mind...
"1968", "15,696 feet", and "Quito only had two reasonably powered FMs". Mt. Rainier is the highest mountain in the Pacific NW at 14,410 feet, and I doubt I'd get anything over 250 miles or so if I were to summit that (which is likely never!) 225 miles seems to be the limit around here at 6K feet for FM reception. Low-power translators have been heard at crazy distances on the other hand. Seven years ago I hiked Bear Creek Mountain in the nearby Goat Rocks Wilderness. Several Bend FMs were loud and clear on the 7,350-foot summit, including the KBNW-AM translator on 104.5...150 watts at 170 miles. This was BEFORE the Yakima translator went on with The Fan, sports radio.

Also for The New Chico...
It wasn't all Rainier causing the Bellingham blockage. Those Yakima stations were extremely strong being at nearly a line-of-sight elevation. 104.1 and 106.5 Richland are both 100KW, 92.9 is 18KW. I was able to take out KDBL slightly at the summit in a couple of spots only, and heard what sounded like classic rock, likely KISM. No bueno on the other channels.
 
Finally have pictures attached for y'all...I have been so busy with other things. Much of the area to the N of Hwy 12 has been devastated by the recent Schneider Springs Fire. I made it up to Round Mountain four days before that fire started. Round was saved because it's not on the Highway 410 side, but forest north of Burnt/Shellrock, Timberwolf Mountain, Edgar Rock (hiked in 2014, near Cliffdell and Whistlin Jack Lodge), Little Bald and Old Scab Mountain are all gone, as is the forest near the Rattlesnake drainage, known for being the filming site for Gary Cooper's 1959 western 'The Hanging Tree.' All in all 100K acres in total gone, and Yakima has had terrible air quality daily for weeks.

Shellrock Peak (on the left of the picture) - which I hiked on 8/14/20! - File sharing and storage made simple
View from Round Mountain summit towards Rimrock Lake, Russell Ridge - File sharing and storage made simple
Mt. Adams + Goat Rocks - File sharing and storage made simple
KSWS RDS on radio - File sharing and storage made simple
CHQM RDS at over 200 miles - File sharing and storage made simple
Lovely Townsend's Chipmunk (one of two spotted in a group) - File sharing and storage made simple
Bear poop - File sharing and storage made simple
Douglas or red squirrel towards the end of the hike - File sharing and storage made simple

There's one more hike planned for me tomorrow - before a rainy cold front comes in and causes possible flooding in the mountains. Planning on hitting Merritt Lake tomorrow, which is west of Leavenworth near Hwy 2. I've never been in this area and while the hike is steep with 2000 ft elevation gain, the hike is short as well. 5.5 miles round-trip. There should be some late-season huckleberries per trip reports as well. Really hoping for one more outing before the berries disintegrate and the snow starts falling in the high country...which means one thing - fall foliage in the shrub-steppe pine forests, and a lot of winter exercise down in the valley. I love having the Palouse-to-Cascades trail available to us. Many times this past winter I did exercise power walks along the east Kittitas portion where it follows I-90. I'm away from Ellensburg - and most of the crowds!
