Have you tried activating a SOTA peak or POTA park but had trouble self-spotting? Do you feel ‘dirty’ self-spotting an amateur radio activity with non-amateur cell-phone or satellite methods? Do you wish you had a simple way to find Summit-to-Summit (S2S) and Park-to-Park (P2P) opportunities in the moment? SOTAMAT is a new way of executing SOTA, POTA, and messaging commands in the field when you have no cell service, no APRS, no computer, and no satellite device. It integrates technologies such as PSKreporter, FT8, PSK31, SMS, eMail, Garmin inReach, Zoleo, Bullitt, SOTAwatch, SOTL.as and the POTA app. It's signature feature is the ability to generate specially coded FT8 messages using your cell phone speaker into an HF radio microphone, and have a worldwide network of skimmers execute your SOTA and POTA commands, or send messages. See breathtaking examples of Paul Mower, VA6MPM, use SOTAMAT to activate the very remote peaks of the Canadian Rocky Mountains.
Would you like to use ham radio to chat live with other hams using your computer but without using the internet? Take a look at the Terrestrial Amateur Radio Packet Network (TARPN) and a growing TARPN implementation: the North Carolina Packet network (NCPACKET). A TARPN is a stand-alone, point-to-point packet radio network that provides communication using only dedicated amateur radio links. You can chat live with or send messages to other hams in your network. To get started, you and a nearby ham set up a “node” based on a RaspberryPi, an inexpensive modem, and modest VHF/UHF radios. Each node can cost as little as $300 even if you have an empty junkbox! Whatever your age or skill level, TARPN is a fun way to learn new things, overcome interesting challenges, and chat with your ham friends!

I spent 25 years looking for a way to easily phase antennas without expensive test equipment such as operational RX bridges and calibrated field strength meters. Using a combination of broadcast and amateur antenna techniques and taking advantage of some transmission line theory, I found a way to build an array using a low cost RX bridge (MFJ, VNA, etc.) to cut the transmission lines. Only low cost SWR bridges (perhaps CB type) are required to tune the array and achieve a near textbook pattern. Another advantage is that the pattern holds together over an entire band rather than only a few kilohertz common to other methods. The presentation will cover the basic approach and overview. A book on it is available through DX Engineering for those who want to dive in further.
RaDAR Rally encourages a challenging and rewarding portable operating experience by promoting the rapid deployment of your station in the outdoors and physical exercise while moving between deployments.
The recent shortage of semiconductors, parts important for electronics, shows us that supply chains can be fragile. What does this mean? It means if we have a big problem for a long time, our advanced radios might be tough to keep working, which could be a problem in an emergency. To solve this, a new kind of radio called the RFBitBanger has been created. It's a type of low power, long-distance radio that is easy to build from basic parts using simple tools. It uses a new digital language, called SCAMP, made specifically for this radio. All the signal work is done by an Arduino processor. What's cool is that the radio has a small screen and buttons or you can even attach a keyboard. It's a full text communications system all by itself. SCAMP is pretty special too. Even though it only needs a simple 8-bit microcontroller, it can do lots of things that digital modes like FT8 can do using small bandwidth and something called forward error correction. The RFBitBanger radio has other helpful features. It can support CW (which is Morse code), RTTY (another way of sending text), and SSB phone (voice communication). We hope that the RFBitBanger can serve as an easy-to-build and easy-to-maintain emergency radio. It can also be a great educational kit. And, it can be a lifesaver when there's a big shortage of parts. Check it out at www.github.com/profdc9.
The ARISS (Amateur Radio on the International Space Station) Radio Pi is a freely downloadable Raspberry Pi single board computer disk image preloaded with software for listening to signals from the ISS and satellites. It was developed for the ARISS SPARKI (Space Pioneers Amateur Radio Kit Initiative) kit. It supports various modes including SSTV (Slow Scan TV), APRS (Automatic Packet Reporting System), and also includes the AMSAT (Radio Amateur Satellite Corporation) FoxTelem software to decode telemetry from the AMSAT Fox series of CubeSats. This presentation will show how to download and run the software on a Raspberry Pi 3B or 4 with a RTL-SDR USB radio dongle. The AMSAT CubeSat Simulator, the CubeSatSim, will be used to generate signals to demonstrate the software in FSK (Frequency Shift Keying), BPSK (Binary Phase Shift Keying), SSTV, APRS, and CW modes. Applications demonstrated include OpenWebRX, Direwolf, QSSTV, CubicSDR, and Gpredict for satellite tracking. If you have a Raspberry Pi you can try out ARISS Radio Pi disk image by following the instructions here https://CubeSatSim.org/RadioPi.
Amateur radio operators may have a requirement to make test measurements of their radio and associated equipment to ensure reliable operation and compliance. to regulations. This testing and measurement requirement is likely amplified when the operator choses to construct or build this equipment himself/herself. This presentation discusses practical and cost-effective solutions for a wide range of technical measurements at VHF and UHF (30 MHz to 3GHz) radio frequencies. Illustrative examples and recommended procedures will be reviewed within this technical presentation. A live Q&A session will be conducted at the conclusion of this talk.
This presentation will discuss SOTA (Summits On The Air) and my experience as a young ham with it. I will go over what SOTA is, why I do it, why others (especially other youth) should partake in it, and other basic information on SOTA operation for beginners. Information concerning gear and different hiking situations, such as what non-ham equipment to bring doing SOTA and different landscapes shall be included. Emergency communications will be touched upon, as when disaster strikes, you may not be in your cozy shack, or you may have to be at the highest location in your area to operate effectively both of which SOTA will prepare you for. Youth involvement will also be discussed as SOTA allows kids to get outdoors and brings a great opportunity to bring in new operators.
