- Comment on Antenna mounted in attic? 3 days ago:
Late to the party; I built and ran both a 10m and 20m window/ladder-line j-pole with phenomenal results. It’s really neat in that it does not require a counterpoise as it has a matching section built in. As such, the radiating element and matching sections do not need to be coaxial, so if you’re mounting in the attic space, you are free to run the radiating element horizontally (performance will be reduced as this antenna’s optimal performance is vertical), and the matching section can have a different orientation.
The 20m version is about 44’ long, so when I only had a 30’ mast, I had to string the matching section horizontally:
On 100W and a 10m tall mast, I was able to reach Indonesia on SSB on 20m. It took some working and good prop, but we made a QSO.
I upgraded to a 15m tall mast and got some marginal improvements, but being in the residential area made it hard to compare since there was always so much EMI:
As for comparison to other antenna types, I have a 7-band OCFD that is quite long, and a massive headache to install (I primarily operate portable), and this j-pole blew it out of the water.
Check out KB9VBR’s video about it: youtu.be/RZv94BvNxrQ
Good luck!

If your circumstances change, you can make a lateral move and invest the net profit in an index fund.

They have!, 2030.
I’m not sure if it’s a mandate, or a goal, but it’s there.
- Comment on Magic Mineral 5 weeks ago:
While it’s no consolation to these current people, they are trying to make the switch to lead-free aviation fuel. It’s partly a regulatory nightmare, and partly a genuine safety challenge; mandating a fuel change in aviation without adequate research and understanding can result in unexpected engine malfunctions.
- Comment on Do drivers in the USA have to yield to alien UFO's? 5 weeks ago:
There’s a whole other section on defensive driving, I’m certain of it.
In this case, you’d be expected to exercise reasonable judgement on whether this UFO may be developing into a hazard. Four-ways on, and pull to the side of the road if it’s safe to do so.
- Comment on Do drivers in the USA have to yield to alien UFO's? 5 weeks ago:
Your last sentence is the answer. Your driving manual probably says “drivers must yield to other vehicles occupying a lane”, which in your example would be a UFO.

They will unfortunately also get filtered. What I do is to direct important callers to ensure they leave a VM, or send and email or text.
- Comment on I'm tired of every game being live service 1 month ago:
Planned obsolescence hidden behind a “feature”.
In ten years, when they want to pull the plug on this game, they will cite dwindling users and “exorbitant” per-user maintenance costs.
They don’t want playable legacies. They want something they can leverage for nostalgia marketing in 20 years, and if you break out the original game, they won’t make any money. Production companies want you to buy what they are offering today, because it pays for new yachts.

I ran into the exact same thing. I ended up calling them to ask all my questions and got guided to me to the KX2 “shack in a box”. They called back pretty quickly and seemed pretty kind about it.
Their site definitely needs some optimizations.

Well… this is practically the story of how I recently ordered a KX2.
The 7300 is great when I want power and lots of options. Turns out it’s a dread to haul when I go out to try just to try and whisper.

Sail there, heave-to and shut off all other electronics. The closest people to you will likely be those on the ISS 409km overhead!
I personally would love to pass through there and try to make some QSOs.

I reckon Point Nemo (48°52.6′S123°23.6′W) might be fairly quiet.
Now to get a research grant and head out there with my rig…
- Comment on Do deaf people play media with sound on? 2 months ago:
I had a friend in high school who had an amazing sound system. He was deaf.
I asked him and he explained that he could feel many of the sounds. So while he couldn’t hear the finest details, there was a lot he could make out.

How expensive and to where can we send money because I’ve gotten a lot of value out of your hosting this instance.

Thank you for these recommendations, I will check them out. Either of these seem like they would work!

Same. Started looking at an Elecraft KX2 as a result as it fits nicely into my planned missions.
8-12 week back order lol

- Comment on Are LLMs capable of writing *good* code? 2 months ago:
I used an LLM to write some code I knew I could write, but was a little lazy to do. Coding is not my trade, but I did learn Python during the pandemic. Had I not known to code, I would not have been able to direct the LLM to make the required corrections.
In the end, I got decent code that worked for the purpose I needed.

- Comment on Random question for today: Considering people who are not amateurs, if you wanted to create increased visibility and participation in amateur radio, what would you do? 3 months ago:
I agree. The FCC exam is a framework for learning. All my follow-on learning, including antenna building and using an NVNA have come from doing it.
