I recently started using voice (SSB) on the HF ham bands, and have made contacts on 15, 17, 20, and 40m. No real DX, but made one foreign contact ~1000mi away and another domestic ~2000mi away.

I live in a city and it's challenging to get a good antenna setup, so it's always a compromise where I am.

Nothing very impressive by ham standards, but it's fun.

Momentum could still be conserved if the velocity is unchanged, but it would mean there's now a lot of kickback once it gets big...

Yeah, the only thing I could imagine would be that image loading/processing uses an optimized library, but a single color is (unlikely but possibly) implemented poorly as a loop over every pixel, with some egregious overhead.

Most likely shit post though...

Oh I wasn't complaining, I was making a bad joke (the cartoon is a stalemate).

One of the coolest parts of The Expanse IMHO was that The Mormons commissioned a giant space ship, and it didn't feel forced or far-fetched.

Ugh, Lemmy is full of stale content.

(Edit: it's a joke. Stalemate/stale content...I chuckled at, and upvoted, the post.)

I've been super happy with it. Knock on wood it's been super reliable. I have a single ZFS drive, take snapshots with various retention policies, nothing fancy.

Another fun thing is to set up a reverse proxy on it as an endpoint for services on your local (home) network which can only be accessed by VPN. For example, my Jellyfin service isn't public facing, but I didn't want e.g. my parents to need to set up WireGuard. So instead they can point their TV to a raspberry pi on their network to access the service


even a first gen RPI can handle Jellyfin reverse proxy over WireGuard for moderate bitrates!

In my experience, the blue (405nm) lasers pointers can far, far exceed the nominal (5mW?) power.

"Necessary, but not sufficient" sums up the role of a degree for a lot of jobs.

Lenna had her time; Fabio will likewise be replaced. But Lorem Ipsum is immortal.

Remind me again, what color was Obama's scandalous suit?

Ah, right, that's why it looked familiar


pretty sure I've seen articles from there posted in one of The Onion communities in lemmy.

 

People often complain about San Francisco's public transit


and to be sure, it's not perfect by any means (multiple separate agencies doesn't help). But the historic streetcars are pretty neat!

They're painted with the livery of various historic streetcars from all over the country (and a few international, I think). Best of all, they run alongside the modern fleet


same route, same fare.

 

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!
