Poor Thomas.
The Federal Communications Commission has removed certain restrictions on ham radio operators, acting on a request that the ARRL made a decade ago.

Thank you very much for taking the time to respond and explain a bit more to connect the dots for me. I didn't notice the built-in @AMRRON group name nestled in the rest of the special purpose groups. I definitely don't appreciate their inclusion, since it is tacit approval of the group, as you alluded to.
Yeah, the FCC document definitely made the potential to leave relaying enabled iffy. I really wish I was a better coder, or I'd fork the code, remove the @AMRRON group and pop up a prompt of whether to allow a relayed message, or only allow to/from trusted parties.
Can you spell it out a bit? I read through the linked sources (that I had access to) and couldn't determine a clear link between the software's developer and J6/OathKeepers/Redoubt movement other than the mode is used by those fringe elements. The "Supports" link is just to the JS8 user manual and the other links don't have clear ties to Jordan or JS8. Admittedly, I'm not a member of the js8call groups.io group, so I wasn't able to read through that source to see if a tie was more clearly established.
I'm all for not supporting those who are trying move the US to christofascism, but avoiding the most popular free-form digital chat mode because of an alleged link is a stretch. It would be nice to have an "allow list" for who you're willing to accept messages for, or allowed recipients, but to me, the protocol is still plenty useful without having message forwarding enabled.
Thank you very much!

I've got an inverted V fan dipole on my roof that's tuned for 20/40, with the peak maybe 25 feet up. It works just fine, even though there's quite a bit of QRM in my neighborhood. The noise floor is S7-S9 across most bands.
I had solely been using a QRP labs QDX (fun kit btw!) and had quite a bit of success within the US, with contacts as far as FL from my QTH in CA. I recently got a FT-897 and have been enjoying the extra power. Had a nice QSO to Argentina (FF92) the other night using JS8 with 25W from CM98. I still leave the QDX on during the day when I'm working to keep an eye on the bands; I feel better about the idea of burning it out than I do a more expensive radio.
I spend much more time on JS8 than FT8, just because it's human interaction instead of computer to computer. FT8 is a great way to get a lot more contacts from a larger number of stations and locations though.
without ever seeing combat
Tell that to the unarmed balloons shot down earlier this year!
Agreed about wishing it would be open source. The most usable OSS combo I've found for using my rspdx over a network is SoapySDR and CubicSDR and CubicSDR hasn't had a release since Feb 2022.
I'm forcing myself to remember that this is just essentially a beta release, with a lot of features missing. With as long as it took them to release this version, I'm not holding my breath to get new features any time soon though.
Looks like it says "The Beverly Estate". I really like the "Cocaine toothache drop" backrest on the pool bench, stay classy 1%!
After a long wait, SDRPlay finally released a preview version of SDRconnect, their new cross-platform software for all SDRPlay SDR receivers except the rsp1. This release includes native network streaming, meaning you can set up 2 devices running SDRconnect, 1 in server mode with the SDR plugged in, and the other remotely connected via the network.
Check out https://www.sdrplay.com/sdrconnect/ for more information. I'm not affiliated with SDRPlay in any way, I've just been anxiously waiting for this release for many months.
Governments should be required to only use open-source software and host their own servers
As a citizen, I appreciate this sentiment. As a government employee, it's misguided at best.
Governments compete with the private sector for skilled IT labor, but the take-home compensation for government jobs often doesn't compare to private, and even retirement contributions and other benefits aren't much better, leaving fewer and less skilled applicants to government jobs, since they don't want to take a pay cut. This leads to a situation where employees that are hired to government don't have the basic skills to maintain servers or host their own systems. Open source is seen as a naughty word, because if the person maintaining an open-source system leaves, finding a qualified replacement will be near impossible. Often times, contractors run complex platforms because the internal talent just isn't present within the government's staff. This leaves governments to rely on the most common tooling, which is unfortunately Microsoft/Adobe/Oracle/SAP dominated, in order to have hope of finding candidates capable of maintaining existing systems and expanding new features/tools. The public doesn't have any desire to increase taxes in order to pay for a more skilled public sector workforce, so we're stuck in this Microsoft and crappy closed source dominated environment. It really sucks to live with on a daily basis, because I know there's so much great OSS out there, but the people surrounding me are completely incapable of getting it running and keeping it running.
I recently built myself a ground plane ADSB antenna. Following the results of an online calculator got me in the ballpark of the lowest SWR being close to my target frequency. At this point, I started adjusting things and noticed that the SWR shifted when I adjusted the vertical angle of the radials. SWR shifted to my chosen frequency when the radials were about 20* above the horizon, which looks like no ground plane antenna I've ever seen before, which either have horizontal or radials angled down at 45*.
With that background, I have 3 questions: 1: What is the implication on radiation/reception pattern of ground plane radials above horizontal? Am I missing out on transmissions close to the horizon and adding vertical gain?
2: Does SWR being lowest with "inverted" radials indicate that the radials are too long? Too short? Just right and I did something else wrong?
3: Is ground plane radial length measured from the attachment point, or the theoretical distance between the end of the radial and the bottom of the radiator? There's a good chance I built these too long, since I measured the radial length from the attachment point, not the base of the radiator (~1cm further)
Thanks for any guidance! Antennas are black magic to me, and I clearly don't know the right terms to put into search engines to find the results to these questions.
Im expecting a “We didn’t start the fire” 2025 edition
Fallout boy released their own updated version 4 days ago. Just like everything else, it doesn't even come close to measuring up to the past.
