⁨Comment⁩ on ⁨BMW Is Showing Commercials On Their Car's Dash Screens And They Want You To Think It's A Treat - The Autopian⁩ ⁨⁨5⁩ ⁨weeks⁩ ago⁩:
Ah right, this was BMW too:

For the past few years, BMW has behaved in a way that seems to treat their buyers as targets for more revenue over everything else. Remember all their subscription bullshit? People hated that, and worked around it, and eventually BMW had to dial that back, because having a subscription for heated seats makes people want to riot.

So, definitely on the “don’t even consider” list.
⁨Comment⁩ on ⁨How to tune my ladder-line J-pole?⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:
Thanks for the terminology correction!

Removing the lights, taking the nails out, and interesting the antenna so lowered the SWR but didn’t improve the tuning.

SWR improved

Moving it away from the 4x4 pillar, anywhere from 3” to several feet, fixed the tune.

I ended up using wood standoffs, since I didn’t have plastic, which seems to work fine.

Tuned my 40m dipole and now I’m getting lots of spots! SWR was >9 before (resunant frequency around 6.3MHz gah), now 1.2:1. Spots as viewed on wspr.rocks :

This is the way it looked in the instructions, didn’t realize they might be setting up orthogonal orientations.

It’s on a Raspberry Pi that’s on the network and the clock looks accurate, so I think the NTP sync is working. Thanks for calling that out though!

⁨Comment⁩ on ⁨Making a 1:1 Balun for Amateur Radio⁩ ⁨⁨1⁩ ⁨month⁩ ago⁩:
This has been puzzling me: The point of coax is to keep all the field inside the coax. But the way a toroid works is to interact with the field. Why doesn’t that prevent the balun from working when coax is used? From what I’ve been reading, is it that the balun is only affecting the current on the outside of the shield by design?

⁨Comment⁩ on ⁨Built a bulkhead to bring antenna coax into my office⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
Thanks!

Yeah, I considered steel wool. Between the styrofoam bottom and the rock wool and the height overall I’m hoping it’s not an attractive entry. The likelihood of sparks seems very low so maybe it’s irrational but the idea of steel wool next to electrical makes me a little uneasy. I may get some coax putty to fill in around the cables when I come back for the grounding line.
⁨Comment⁩ on ⁨Built a bulkhead to bring antenna coax into my office⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
The dipole has a coil of spare coax closer to the antenna feed point, which I think also serves as an RF choke.

The VHF/UHV J-pole didn’t have any extra, but agree it would’ve been nice to keep a little extra coil if I’d had the option.

⁨Comment⁩ on ⁨Field day is next week. What's everyone doing?⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:
There are a couple clubs in/near my city. I’m planning to stop by one with the family after we do some errands, hear about what folks are doing, see if my kid wants to try making a contact. Also I may see what folks have to say about antenna placement.

I’ve been wanting to do a fox hunt and some clubs have set that up at field day I think.

Are swap meets often part of field day? I’m on the lookout for an SWR meter and/or external tuner, so I may watch out for that.
⁨Comment⁩ on ⁨How to know if that job will crush your soul⁩ ⁨⁨2⁩ ⁨months⁩ ago⁩:

What’s the lived experience of the workers there whom you trust? Do you have evidence of leaders in the organization making hard choices to do the right thing?

Very helpful, and very hard to get around if you don’t already have a connection.

Though in my experience, people will tell you a fair amount about the organization indirectly; and will often answer direct questions.
