Descriptive would be "Bus Stop Systems". No, drop the "Systems", just "Bus Stop".

That's for sure. Here's what an Ettus B210 (now $1472, not cheap) looks like with a fundamental at 145 MHz. 3rd harmonic is only 10 dB down. Power was 0 dBm (with a 20 dB pad on the analyzer input). https://www.w6rz.net

Amateur radio still has 44.0.0.0/9 and 44.128.0.0/10. Not exactly a shortage. Also, they are giving back to the community. The largest grant so far was $1,620,000 to save a radio telescope for the MIT Amateur Radio club. https:&#

I2O was definitely a pivot. The original i960Kx, i960Cx and i960Jx had nothing to do with I2O. I2O was introduced later with the i960Rx series. I developed an i960RP design back in the late '90s for an MPEG-2 encoder PCI card. The enco

Back around 1985 or so, there used to be a glut of loose Thai bud in the Bay Area. It was dense and dark brown (like chocolate). But the importers eventually got busted and that was the end of that.

The fine Colombian. When I was in high school back in 1975, we somehow got our hands on some real Colombian Gold. By far the best marijuana I've ever smoked (and I live in California). If they can export that kind of strain to the US,

I'm running Ubuntu 21.04. As for using it as a daily driver, you might be disappointed with the performance. It's slower than a Raspberry Pi 4. Also, no Firefox or Chrome browsers (yet). You have to use Epiphany. It's really

I have one. They shipped back in the beginning of June. They're in stock at both Mouser and Crowd Supply. https://mouser.com/ProductDetail/SiFive/HF105-000?qs=zW32dvE... https://www.crowdsupply.com

There are no ports of Firefox or Chrome for RISC-V. I believe the JavaScript engine is the problem.

It seems like Apple actively tries to ruin the functionality of libimobiledevice with each release of iOS. It worked the best on my iPhone 6 and iOS 9.3.4.

I use it for tethering when Comcast goes down. You also need ipheth-utils.

You wouldn't be happy with the Unmatched. At 1.2 GHz, it's slower than a Rpi4. Even a Beagleboard-X15 (2 core armv7) is faster.

Back in the dark ages before direct deposit, it was much better to get a paycheck biweekly (every other week) than bimonthly (15th and last day of the month).

The Intel tool for this (running on MDS-80 "Blue Boxes" and ISIS-II operating system) was CONV86. I used CONV86 way back in 1983 to convert a fairly large (back then) 8080 assembly language code base to the IBM PC. Worked perfectl

It's a mix of wideband and narrowband, but everything is frequency hopped. In the waterfall, the strong wideband bursts have a red colored center frequency. The narrowband bursts are just vertical lines.

> It’s a hazard for an 11 year old to pitch or hit against 8 year olds. Heh, I played Little League in a very small town back in 1968-69. In order to have enough teams, the league was 9, 10, 11 and 12 year olds. You had 12 year old almos

I agree. Current day La Costeña on Middlefield is nothing to write home about.

La Costeña is pretty good, but my favorite was a place called Carambas in a strip mall on the corner of Mary and Washington in Sunnyvale. They had a jalapeño burrito that would make your face sweat. That strip mall is long gone now. Even wh

That was about radar altimeters, not GPS. That 5G band hasn't been occupied yet, it's still being auctioned (and it's already the largest auction in US history). https://auctiondata.fcc.gov/public/project
