LOS it would have been fine unless the repeater is unusually deaf. I have hit LA area repeaters from the 10kft ridge north of Telescope Peak in Death Valley NP with my HT no problem (250km). Easy to get into Vegas area repeaters from there too (175km). See also: working the ISS with HTs.

Looks like a VHFish version of a folded terminated monopole. www.md0mdi.im/the-folded-m...

I have a pretty similar looking interferer at the same frequency that comes on every night at sunset. It's a neighbor's garden LED light strand. They turned it off for me for a while but it's back recently so I guess they didn't replace it.

Really have to wonder whose side the issue is on with Apple now a direct competitor. I've also been a long time user on Win and I've found it getting more stable and consistent of late (though there are occasional hiccups)

That's a useful rule for release, but I was talking about the next section, which recommends 50-70% coverage for the EP and references the next figure with a 66% by printed area comment. The example EP land is 6mm^2, with 4mm^2 of paste. All of this is dependent on the stencil thickness of course.

Where did you land at? I tend to follow the 66% coverage by area that TI recommends in their QFN guide, but I've found it's sometimes still a bit much for heavier parts.

This is super interesting, did they mention the primary use case?

Haha! This sunspot migration thing was a cool fact presented by @tamithaskov.bsky.social when she spoke at the WWDXC convention in 2019. I'm probably not recalling it perfectly, but that was a great talk!

Sunspot numbers are one way to measure it. The other is the band of sunspots have reached the suns equator in the south and are almost there in the north. The sunspot complexes tend to migrate from the poles to the equator over the cycle and then die out, restarting again at the poles

Vertically polarized Yagi usually points towards CB. Appears that there's an 11m vertical on the back patio leaning the other way too. The Amateur Radio license map also doesn't have any hams with a license address in Strong, you have to go to the next town over to find a ham.

Yes, more overlap on 40m would be 👍. We chased DX on 40 anyway, but it was one station on top of another across the whole shared 75kHz. I was op both nights when 40 was open to EU and wasn't able to run with 1.5kW and 3el at 1λ. Ran JAs no prob. Lack of DX on 20 hurt. 10% lower score than last year

Got it! Walk up to them, give them a pet, check their teeth and tail, then whack them over the head. We grew up with these "river rats" water skiing on the Brazos. They could be surprisingly aggressive if you happened to fall too near their nests. They'd even jump into the water and swim after you.

10 barely showed for us at KZ1W. A few loud EU stations our Sun morning, enough to pick off some extra mults, but never enough to get a run going. 15 and 40 were overcrowded. We had the benefit of a good supply of JAs on 15 for a few hours after each sunset. 20 was noisy, had to point JA to hear EU.

Don't get a Rivian then... My BLE scoopers pick them up constantly on my Home Assistant install as they drive by. Presumably they roll something as I can't imagine over 100 Rivian have driven by.

You might reach out to dk0tu.de and see if that's something any of their members might be interested in.
