I dig ham radio, telephones, computers, privacy, vim, and my dog.

A Canadian friend introduced me to putting malt vinegar on my “fish and chips”. Was one of those eye opening “why haven’t I been doing this all my life!” moments.

First Venus bounce with the Dwingeloo telescope – Dwingeloo #AmateurRadio Telescope | CAMRAS
On 22 March 2025, we used the Dwingeloo telescope to successfully bounce a radio signal off the surface of Venus. At the time, Venus was in its closest approach to Earth at about 42.000.000 km. Such a conjunction happens when Venus is between the Sun and the Earth, and happens approximately every 580 days.

Re: Delete, Delete, Delete - FCC Initiates Broad Inquiry on Rules to Delete or Amend

The American Radio Relay League (ARRL) is the national association for amateur radio, connecting hams around the U.S. with news, information and resources.

In a Public Notice titled “In Re: Delete, Delete, Delete,” issued on March 12, 2025, the FCC is soliciting public input on any FCC rules in any service that members of the public believe should be deleted or modified “for the purpose of alleviating unnecessary regulatory burdens.”

This is very one sided. There's SO much more to ham radio than voice.
Maybe the question is "How do we get people to think that ham radio is more than just a voice call?"

If you're in the US, you can test online! https://hamstudy.org/sessions/remote
I do agree that the test itself could be tuned down a bit, especially for the tech license. hamstudy.org also has all of the test questions available online to help you study.


Get some ideas on what you can do to get younger generations interested and active in the amateur radio hobby.

Don’t let nestle find this out

Try kagi search! It actually has a “lense” or search option that lets you directly search federated services like lemmy: https://help.kagi.com/kagi/features/lenses.html

From experience: I can say that a topic instance such as ours is easier to moderate due to the fact that it's narrowly focused and the number of posts here are small in comparison to a general instance such as lemmy.world or sh.itjust.works. I moderate the users that join pretty fiercely so I know that the only people that join/post from here are interested in amateur radio in some fashion. I also think we are a bit lucky in how we moderate with the fact that hams tend to moderate themselves and others already through their acts and experiences with radio communications in general (thanks everyone!).
I sorta see how you can view niche instances as having sub-subreddits. Generally though, every community out there is just a subreddit and you can subscribe and post to any of them, even though some communities do share the same topics (there are lots of other amateur radio communities out there).
I definitely like seeing people creating communities here, as long as they are amateur radio focused (see rule 5). I also would suggest making an account on a general lemmy instance as well, in case you would like to make a more generalized community. I think it's probably just good practice on any federated application to create accounts on multiple instances.

[Tech Minds] built one of those cheap automatic antenna tuners you see everywhere — this one scaled up to 350 watt capability. The kit is mostly built, but you do have to add the connectors and a few other stray bits.

Also note that these are spaces and not rooms. They work just a bit different depending on your client.

If I remember right, there was a pretty big change in how pictrs(photo management) worked with lemmy after 0.19.3. There were a few breaking changes and Postgres updates that would take an instance down for a while as well. Not sure if that’s the reason why but it made my instance stay on 0.19.3 for longer than it should have.

You can search instances and communities with https://lemmyverse.net/communities

As an instance owner and moderator: that’s a horrible way to look at things. Just throwing the onus onto someone else is irresponsible.

I’m all for it as long as people know that posting on something like mastodon and tagging a lemmy community will then make a post in that community. Could make for great discussions, but could also lead to a lot of posts/spam in the communities.

Those are all great options for sure. And while not an exact answer to your question, you could maybe go a bit simpler (and cheaper) for just 2, 10, & 20m like an end fed half wave.
Thoughts on how you’ll run it to your second floor?

It’s not a slogan, just the title of the article 😊 it does go on to state that the spirit isn’t much different and how it’s used differently today. Glad you like lemmy.radio!

We hear a lot about how ham radio isn’t what it used to be. But what was it like?

To facilitate operations, scripting, and automation on Brandmeister, we are now starting the complete removal of Radio IDs that do not comply with the internationally recognized MCC (Mobile Country Code) numbering system.
If you currently have a device connecting to Brandmeister with a Radio ID starting with the digit “1”, please read the following carefully:

For lemmy: it's mostly link sharing, so I'd mostly see posting about *OTA experiences, pics, questions here in the POTA/SOTA communities.
Mastodon, on the other hand, would just be one way to show something like that since it's more time related and ephemeral. Bot was my first stab at something like you mean, but I do think there could be something to auto-post with all that data.
And while not on the fediverse: I use hamspot for something like this. It flips the onus of posting a spot to actually listening FOR a spot from people you know around the fediverse.
BUT if we want to let our ideas get REALLY wild with it: I could totally see a federated service for spotting or any *OTA related activity. Different instances handing different kinds of spots. Parks or summits or islands being different items that people can subscribe to, spot from, and activate. Just spit ballin'.

I could see a community used for spotting. Not sure how the browser extension part would work.
I see people post a sorta self-spot on mastodon all the time. Something that might be nice is a mastodon bot that could read a certain hashtag or if it was @ed so everyone could follow the bot to see who is activating.

Morse Walker is a CW pileup trainer with modes such as POTA, SST, and CWT, plus beginner-friendly features, including adjustable speeds and Farnsworth spacing.
Great web app to practice your CW for CQs, pile-ups, contests, and POTA

First two-way contact via geostationary satellite bounce
In an exciting first, we managed to successfully complete a two-way contact by bouncing a signal off a geostationary satellite. The satellite in question, Inmarsat GX-5, is stationed at an altitude of over 35,000 kilometers, and together with Dan, HB9Q, in Switzerland, we alternated between transmitting towards the satellite and receiving reflections. This first ever amateur QSO over geo satellite the remarkable capabilities of modern amateur radio technology when paired with large, high-gain dishes.

On Politics and Proton - a message from Andy
Copied from the reddit post:
Hi all, last night, a post from last year from my personal X account suddenly became a topic of discussion here on Reddit. I want to share a few thoughts on this to provide clarity to the community on what is Proton's policy on politics going forward.
First, while the X post was not intended to be a political statement, I can understand how it can be interpreted as such, and it therefore should not have been made. While we will not prohibit all employees from expressing personal political opinions publicly, it is something I will personally avoid in the future. I lean left on some issues, and right on other issues, but it doesn't serve our mission to publicly debate this. It should be obvious, but I will say that it is a false equivalence to say that agreeing with Republicans on one specific issue (antitrust enforcement to protect small companies) is equal to endorsing the entire Republican party platform.
Second, officially Proton must always be politic
