this was always bound to happen as we expand our presence in space.

Yes and no


from a different article:

Radiation associated with Starlink satellites was detected at observing frequencies between 110 and 188 MHz, which is well below the 10.7- 12.7 GHz radio frequencies used for the downlink communication signals.

(The original article said 5M radiation, which should be around 60MHz.)

So Starlink is emitting RF in spectrum where they shouldn't, which is avoidable, but takes effort.

My guess, and I could be wrong, is that this could be related to something other than the radio(s), such as switching power supplies finding opportunistic structures from which to radiate.

Sure. But this is kinda just accelerationism/xenophobia, no? For example, replace "Idaho" with "Mexico" in your argument, and it gets pretty ugly pretty fast IMHO.

ID residents should be banned from receiving medical care in WA.

But I think accelerationist policies often hurt vulnerable people...

An incidental exchange of earwax with your (romantic/sexual/life) partner is


how do I put this?


not particularly noteworthy for a lot of folks...

...and I don't see it motivating people to go vote.

But it can do the opposite perhaps


"motivate" people to stay home who would otherwise vote R. Not that, in general, we should be celebrating voter apathy, but I think that some of these endorsements could dishearten folks enough that they end up abstaining.

Track stands! Not a contradiction to your statement at all though: you need to be moving just ever so slightly.

With a fixie it's easy, because you can pedal forwards and backwards in tiny amounts. With a freewheel, it's trickier but you get the hang of it with practice. Ideally you'll have an incline, so you pedal forward to go forward, and ease up to slide back. After some practice I can use the raised reflective paint from e.g. crosswalks as the "incline." This miniscule motion is enough to balance


and like you said, it ain't the angular momentum that does it.

I think you need to include energy cost in the preparation stage. Bread requires a hot oven, which is a real amount of electricity


it's close to $0.40/kWh where I live. From this link it says that a bread maker uses only .36kWh, but an electric oven would be more like 1.6kWh. So bakita single loaf of bread, you end up with a not insubstantial fraction of the total cost going to heating the oven.

Of course, many bulk foods require heat, so it gets a little sticky this way. Oats/oatmeal probably wins out here, as you can just soak them overnight.

A bit nuanced in drought-prone places, though


stone is, well, drought-friendly, but a typical lawn is most certainly not. Best would maybe be drought-resistant native plants...

Ford, Harley- Davidson and Lowe’s are among the companies that announced they would no longer participate in the Corporate Equality Index.

Meanwhile, here are the ones that did well on the Corporate Equality Index link.

Right. But I think it's a mischaracterization to represent the EC as a "technicality," as it's very central to the way voting in the USA works. Don't get me wrong, I think it's stupid and should be abolished, but it's very much ingrained in the voting system.

I think I'd counter your example


keeping the sports theme


by saying it's like the World Series: it doesn't matter if there are three absolute blowouts, all the matters is who wins four games. So you could easily win the World Series, but have fewer total runs across seven games (game = EC votes, runs = popular).

(Again, I think the EC should absolutely be abolished.)

Ended up with the Yaesu FT710, with a G5RV Jr. in the attic. Internal tuner tunes 40-6 with the exception of 15m and 17m. Very pleased with it so far! Several digital DX so far (Australia, Brazil, Samoa, Japan, Alaska, Hawaii


I'm at CM87/California).

To-do list includes low loss coax (100ft run of who-knows-what currently); debug intermittent Ethernet issues (Ethernet runs parallel to feedline


choke balun/better choking of feedline?); possibly get remote tuner (one step at a time...). Fun stuff!

Yeah, "serious" cycling


a sport where a $1k bike barely qualifies as a bike, $5k gets you something rideable, and $10k gets you a pretty decent bike


is so anti-consumer!

(I love cycling, and I'll defend spending more on my power meter pedels than I would spend on a decent used bike. More bike lanes everywhere please!)

 

Noticed a few days ago that Sutro Tower's red blinking lights are now white. Just asked them on their website form, but wondered if anyone else knows the story with this.

Personally, I miss the red ones!

Howdy!

I got my Technician in early 2000s, and last year finally upgraded to Extra. Looking to set up a very basic shack.

I'm looking for an HF setup, with most of my use probably using digital modes, but would like the ability to use voice.

Current transceiver is on loan from girlfriend's dad, a Ten-Tec Scout 555


50W HF unit with separate modules for each band. One limitation of this is that the modules set the mode, so it's LSB on 40m, making e.g. FT8 not possible (without some hacking of code or perhaps hacking the module).

Antenna is end-fed with an off-the-shelf 49:1. Currently only have 20m half-wave, but have just enough room for a 40m half-wave in the attic, which is the ultimate goal.

For digital modes, it looks like there are sort of 3 classes of radio:

  • "full digital" where the radio has e.g. a USB port and handles audio, transmit, and frequency set.
  • Some computer-control with RS232, but uses computer audio+adapter to transmit.
  • No digital, use adapter to transmit. This is what the current setup uses (and it works great!)

I'm leaning towards a conventional transceiver, e.g., something from ICOM, Kenwood, Yaesu, (or others) rather than an SDR unit. I'd like the ability to go up to 50-100W if possible.

I don't have a hard-and-fast budget; would like to keep it <$1000 if possible; mostly just looking at used transceivers. Something like a Kenwood TS-590 looks pretty amazing and very "plug-and-play" (but pushing up against price). Something like a Yaesu FT-920 looks pretty feature-rich too; and even something more affordable like an ICOM 706 or even a 725 is probably more radio than I need. Or just grab a new 7300 and call it a day!

Anyway...clearly, I don't know exactly what I want, but figured I'd ask folks with more experience if they have any wisdom. Thanks!
