Design and build a functioning amateur radio antenna using non-traditional or improvised materials (e.g., tin cans, coat hangers, umbrellas, plumbing pipe).
If it looks absurd and still gets on the air, you're doing it right. HRV will have connectors, soldering stations, and some raw materials for available for use. See what other materials you can find to make the best improvised antenna!
Rebooted this year, enjoy a traditional fox hunt tracking down the hidden transmitters.
Construct, test, and use a real antenna. Two kits are available: a VLF Foxhunt Loop to win your local fox hunts, and a LoRa Yagi antenna and become the alpha-ham dominating oppressive gain and narrow beam width.
Join us as we condense the sum total of humanity's antenna knowledge into 30 gripping fun-filled minutes of building, testing, and using a built from scratch antenna. Afterwards the instructors will be around to help with assembly in the Village.

in this talk we review how amateur radio were used in the relief effort in NYC Sept 11.
Meshtastic is an innovative open-source project leveraging LoRa technology to create affordable, robust, off-grid mesh communication networks. This presentation offers an approachable introduction to Meshtastic and LoRa, covering essential concepts and practical applications. Participants will gain foundational knowledge of mesh networking technology, along with a hands-on demonstration of setting up a Meshtastic network using a readily available ESP32 device and a smartphone. Ideal for both amateur radio enthusiasts and newcomers to mesh networking, this session will highlight how Meshtastic empowers users with resilient communication in remote and emergency scenarios.
This presentation will detail the design and implementation of a Meshtastic-based command and control infrastructure. By leveraging the Meshtastic network for out-of-band communications, operators can achieve secure, decentralized monitoring and management of Linux hosts in hard-to-reach environments. Whether supporting a remote dropbox deployment or a distant ham shack, this solution enables encrypted shell access and configuration changes using a low-cost ($25) LoRa radio over extended ranges. Although not intended for high-bandwidth tasks, it provides an efficient platform for debugging, troubleshooting, and command execution in constrained network conditions. Furthermore, by utilizing the existing Meshtastic mesh, users can often avoid the complexity of building a dedicated network.

Satellites are constantly orbiting the planet and beaming information back to us. Some of the most interesting information is weather images. As it turns out, it is very easy and cheap to pick up those signals and get a real-time view of your current location. In this talk I will go over what is out there, what you need to get, and the open source software stack to generate amazing images.
