Foundations of Amateur Radio - Becoming Mode Agile #podcast
Over the years I've talked about different ways of using our license to transmit. I've discussed things like modes such as voice AM, FM, and SSB, and digital modes like FT8, WSPR, RTTY, FreeDV, Hellschreiber, Olivia and even Morse code.
Recently it occurred to me that there is something odd about how we do this as a community. Now that I've realised this it's hard to unsee. Let me see if I can get you to the same place of wonder.
Why is it that we as amateurs only use one such mode at a time?
Let me say that again. With all the modes we have available to us, why do we only use one mode at a time, why do we get our brain into the mindset of one activity, stop doing that in order to move to another mode?
It's weird. Amateur radio is what's called "frequency agile". What I mean by that is we are not restricted to a fixed number of channels like most, if not all other radio users. We can set our transmission frequency to whatever we want, within the restrictions imposed by our license

Integrate a vibration/earthquake sensor into your ESP32-based LoRa Meshtastic Node with our guide, suitable for boards like Heltec V3 Lora, TTGo, or T-Beam. This setup allows the network to broadcast warnings when seismic activity is detected.
VarAC - does anyone use it and what is your experience?
VarAC is a modern HF P2P real-time chat application for the hamradio operator, using the VARA protocol

Foundations of Amateur Radio - Playing Games On-Air #podcast
One of the basic aspects of being human and growing up is the process of learning. From a young age we explore our environment, play with others, have fun, fall over and bruise our knees, get up and try again. The playing aspect of this is often discussed as a way to keep things interesting. We add a competition element as an added incentive, so much so that we formaulate it into global competitions and call it sport.
As a species it might surprise you that we spend about 1% of all Gross Domestic Product on sport, compared to science, which is about 2% of Global GDP. To give you some context, Agriculture accounts for about 4%, Manufacturing is 15%, Industry is about 26%, and Services account for roughly 62%. If you noticed that this is more than 100%, take it up with the World Bank, I'm a radio amateur, not an economist.
Over the years I've explored different aspects of our chosen hobby of amateur radio. Time and again I return to experimentation, learning and having fun. Now I absol
When we first spotted the article about a one-transistor amateur radio transceiver, we were sure it was a misprint. We’ve seen a lot of simple low-power receivers using a single transistor, a…
The WisMesh Board ONE Pocket is a premium Meshtastic handheld with great build quality, modular expansion, and a larger screen. While it’s well-designed, its high price and average battery life may push budget-conscious users toward more affordable alternatives.

Advice on getting back into the hobby?
It seems my interest in ham radio was the result of ADHD hyperfixation that ended after a few years. I primarily played with CW and digital on HF, and satellites on VHF+. My interest petered out some time in 2023, and I want to get back in but can't find something that both captures my interest and doesn't require more purchases.
Foundations of Amateur Radio - What is Amateur Radio really about? #podcast
When you join the community of radio amateurs, or when you briefly look over the shoulder of the nearest devotee, you're likely to discover that this is a hobby about a great many different ideas. Over the years I've discussed this aspect of our community repeatedly, talked about the rewards it brings you, about the camaraderie, about communication, learning, research, soldering, disaster recovery, public service, and all the other thousands of activities that this hobby represents to the world.
While all those things might be true for some, they're not true for everyone. Many amateurs get excited about antennas, some immediately, some eventually. The same can be said for all the other points of what we think of when we discuss our hobby with others.
Recently I saw a random comment on social media from a person who was having issues with their mobile phone on their property. I considered and ventured an opinion about what might be the cause and how they might go about discovering wha
For those who do public service in the US, do you use a dedicated dual band VHF/UHF radio, or the same all-band, all-mode radio you use for other activities like POTA?
I’m inclined to go with the long-term cost savings of a radio that does everything but wondering if others have good reasons to go with a dedicated, simplified rig. I would be purchasing used equipment either way. And would have to use either radio for base as well as mobile use. #PublicSevice #VHF #UHF
[EDIT] to clarify I'm in the US, where "public service" (being communications support for primarily bike and foot races, where I live) does indeed happen on the amateur VHF/UHF bands. This is who I volunteer with, for context: https://www.hpsnc.org/. They also require a mobile (not handheld) radio at least 25W.

Antenna was about 20m of random wire coil on a sound card, recorded with Friture.
When the AMSAT-OSCAR 7 (AO-7) amateur radio satellite was launched in 1974, its expected lifespan was about five years. The plucky little satellite made it to 1981 when a battery failure caused it …
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.

What's the point of owning a geochron?
So I've seen these things mentioned around various ham related communities, and my immediate thought was why is this its own thing instead of an app/website/software? They go for nearly $500 at HRO. At that price it'd better cure cancer.
Yes I did recently learn geochrons used to be mechanical time displays and have been around for a long time, but in a vacuum I don't understand their utility when stuff like ham clock exists.
