In November 2022, a team of 12 experienced Dxpeditioners will operate from the #2 most wanted entity in the world: Bouvet Island. Sailing on board MARAMA, a 101ft oceanic ketch designed for extreme expeditions, they will setup a camp on Cape Fie and operate multi HF stations on all modes during a period of 20 days weather permitting. Join us for this presentation where we will discuss our plans and give you the last update on our preparation. Until then you can visit our website: www.3y0j.no
Amateur Television offers unique benefits. It may seem complicated and expensive but its not. This presentation shows you how to participate simply and for free. It also shows you a few options to get more out of ATV if that's what you want. We'll take the mystery out of what equipment to use in different environments and where to get it. We'll show you how to make the most of your budget and skill level. We'll keep it simple and sensible to get started and we'll show how you can kick it up a notch to get the most out of ATV when you're ready. Tune in to see what's right for you and how you can be an ATV celebrity.
Carl will review the predictions for Cycle 25, discuss the current status of Cycle 25 and talk about what to expect propagation-wide for the next year or two.
Antenna specifications concentrate on maximum gain but often ignore an equally important characteristic, the take-off pattern. You are not getting the performance you expect if the incoming signals are coming in at angles that don’t match your antenna. This presentation looks at signal arrival angles, the factors that affect the antenna patterns in the vertical dimension, and what you can about it.
I launched a pico balloon from Oklahoma on July 20th, 2021. It carried a Skytracker payload developed by Bill Brown, WB8ELK. I got APRS reports from it for ten days. The SSID was N4KGL-11. It cruised above 28,000 feet and gave us much entertainment. Boy, this pico balloon flight was fun!
This talk will discuss baluns, ununs, and transformers used for broadband impedance matching and isolation for multi-band wire antennas such as Off Center Fed Dipoles and End Fed Dipoles. It will present 1:1 and 4:1 transmission line baluns used for isolation and impedance matching. A 4:1 hybrid balun will be presented. Finally, it will present transformers used for higher impedance ratios required for end fed antennas. The discussion will include an overview of each type followed by construction details including materials to use, mechanical considerations, and electrical considerations. Designs for a range of power levels will be presented. Each of these designs has been built, tested, and used in successful antenna designs by the authors.
The audience will laugh, will cry, and will take away practical lessons from 12 years of operating ham radio contests in the mountains and deserts of California in a converted television news van.
There is always a lot of DX to be worked during a contest, but not everyone has thought about how to approach it. This presentation gives several examples of the best ways and tools and techniques to use to increase your chances
Shortwave radio signal propagation is a fascinating area of exploration and discovery, and is the backbone of world-wide amateur radio communications. How does shortwave radio signals get from that distant amateur radio station, to our local radio station? How does space weather interact with shortwave radio propagation? What will we notice about the next few years in this new Sunspot Solar Cycle 25, in relation to propagating our HF radio signals around the world?
I want to present the CW Academy, what is offered and what it takes to succeed.
This presentation is a deep dive on work done on for Phase4's DVB-S2 FPGA implementation (https://github.com/phase4ground/dvb_fpga). We'll show the system's architecture and its data model, how data flows between components, details on design for debug and how the design communicates with the external system. This implementation has been tested in prototyping platforms and there's currently effort to demonstrate it over the air. The idea is to share know-how on designing such systems to fill in the gap between basic FPGA demos and complex designs.
Exciting new development in sensor technology of E (electromagnetic) and H (magnetic) enables research and long term monitoring of fault lines at an affordable cost. The most serious DX operators and station are located in areas were we have extended openings. These are created by leaking electromagnetic fields in weak crust zones. It allows a glimpse of the telluric currents, while micro quakes occur. This new tool, in conjunction with the RF-Seismograph, will enable us to better plan for these events at a very low cost.North Vancouver, where the RF-Seismograph is located, is such a place. It allows us to detect these emissions, monitor earthquakes and make DX connections at the same time.
I built a service on which you can get a text message when your buddy's callsign is calling out on DMR networks. This is available for free at hearham.live. This makes it easy to hear when someone is on the radio without getting out your DMR radio and having it turned on and listening all the time.
In April 2020, my wife and grandson got permission from our VEC to do an on-line exam using Richard Bateman's ExamTools software. We managed one test in an hour, working from our kitchen table. We expanded and recruited more VEs and applied technology to the process until eventually we hit our high-water mark of 125 applicants tested in 3 hours by 100 VEs. Today we have over 40 VEs organizing sessions with 100s of VEs from all over the world. We were the first to use Zoom breakout rooms to do multiple simultaneous exams using dozens of VEs. We were the first to adopt a standard Spanish-language translation of the NCVEC question pool and now have a three teams of VEs running regular bi-lingual exams. This is the story of how we did it and what we see as the future of on-line exams.
As a relatively new ham, I discovered the hobby from a variety of interests. Rather than casting a wide net for new, younger hams, I'll talk about finding them within groups and hobbies that should lead more naturally to a lifelong love for our hobby. It worked for me!
A basic introduction to the sun and its effect, and how the ionosphere works. We hear a lot of terms used in our hobby, such as sunspots, CME, K index, solar flux, etc., but what do they mean, and how can we understand them. These concepts are presented in an interesting format with the goal of helping us better understand their role. My desire is to help in understanding more advanced presentations. With Cycle 25 upon us, this will help in understanding its effects.
The popular NanoVNA has the capabilities of instruments costing 500 times as much just a couple of decades ago. We will explore some of the less known uses of the VNA, which will solve a lot of long held misconceptions about transmission lines and related topics.
Callum discusses how to defeat radio filtering, microphone technique, pileup, special events and calling CQ. How to achieve more - with less.
In this session George will be joined by the rest of the Ham Radio Workbench team will be live talking about projects and will take listener questions. The team includes Rod VA3ON, Mike VA3MW, Mark N6MTS and Vince VE6LK.
I have built the K6MM 160M Helically Wound Vertical which provides a great signal in a restricted area. K6MM, John, first published this in QST in 2009. With Johns help, I have added some 3D printed guides and put it together in a short time.
Answering the Call is a get-up-to-speed-quickly presentation that will give you the basics of what you need to get outdoors and get on the air. You will learn how to combine HF Portable with camping, select the right gear, choose the best operating location and employ tactics that will ensure each trip out ends in success.
There is no need to build all metal magnetic loops. How to use self-adhesive copper or aluminum foil tape for an example inexpensive 4 ft. HF loop that exceeds the performance of many home-brew and commercial all-metal designs. Plus, it uses a unique easy to make low cost home-brew tuning capacitor -- no vacuum viables -- no massive rotary tuning capacitors.
Homebrewing software can be as much fun as homebrewing hardware, and making copies for friends is much easier. This presentation shares 50 years of experiences pioneering homebrewing software for amateur radio, in 8080 assembly language, Basic, Pascal and Delphi. Programs included logging, an ARRL sweepstakes simulation game, OSCAR orbits, satellite telemetry decoding and displaying, automatic packet radio and AMTOR operation, enhancing FT8 communications, DX chasing and the DXCluster and software flown on the Space Shuttle STS-35 mission. The presentation also discusses the need for standards to enable software sharing.
I will present a PowerPoint slide show and take questions during and after the presentation.
You, too, can capture the MAGIC of six meters. It takes some time and skill but you’ll achieve incredible results from an average station. This presentation covers propagation modes, equipment, antennas, software, operating awards, and contesting. This will be a superb preparation for your own efforts on six meters.
HamPi is a free software distribution of approximately 100 ham radio applications for Raspberry Pi users. I released version 1.0 of HamPi a week before Field Day 2020. Putting hundreds, if not thousands of hours into it, I have been updating it once a quarter, and I plan to release a major update -- version 2.0 of HamPi this December. HamPi version 2.0 will be based on the newly released Raspberry Pi OS based on Debian Bullseye (ver 11). I want to underscore how popular HamPi has become with the Ham Radio community. To date, there have been well over 50,000 downloads of HamPi. Users hail from all over the US, and also internationally too.
I've been thinking about a potentially new kind of contest, and I'd like to have a round table discussion with experienced contesters to figure out how to make it as fun as possible. My idea is: using only 5w HT's FM mode, which is the transceiver of choice for new hams, we transmit a set phrase across adjacent grids from one coast to the other and see how distorted the messaged gets by the end. Also, by tracking each message as it works it's way along from ham to ham, we'll get ideas about potential EmComms pathways. Challenges to discuss: - Message tracking software - Scoring, multipliers - Using multiple messages to improve chances of full path completion - Open discussion
OJ0C DXpedition to Market Reef in June 2021, IARU contest on July 10-11, 2021 as OF0HQ from Åland Islands. Operating from Radio Arcala OH8X, Arctic Circle, Finland the biggest ham station on Earth in July 2021.
A discussion and demonstration of having a two-way conversation using the highly-resilient keyboard-to-keyboard digital mode for long-range shortwave, the Olivia digital mode.

Public Service is one key reason tens of thousands of Americans are Amateur Radio Operators, and one perfect example of how hams give back to their communities is the annual MS150 City to Shore bike ride. In 2021, 149 Amateur Radio Operators kept nearly 4000 bike riders safe and secure along the 75 mile route. This episode of What Hams Do... The TV Show, explores the event an the people who make it happen.
With the advent of calibrated S-meters and quality power supplies in Amateur Radio stations many years ago, the old RST system became obsolete. Genuine signal reporting can be useful for routine operating, but signal reports do not make a meaningful contribution to fast operating situations like contesting and DXing. Stereotyped signal reports are not only unhelpful, but also contravene FCC regulations. We need to leave RST to history and embrace an accurate system which is appropriate for the 21st century.
Whether considering radio or telephone options for an offshore sailing passage, or coastal power boating, there’s something for everyone in this session and the Q/A that follows. The talk will include a cost-benefit comparison of equipment for maritime use; discuss meteorological data collection methods; review licensing requirements; and point out the unique operating environment of maritime mobile gear with answers to the question: “Can I use my shore-based radio on a boat?” The Q/A discussion will include RFI, grounding, and even suggest creative antenna experiments (Hint: That sailboat mast looks a lot like an Inverted-V dipole). Most importantly, the session lists valuable FCC, Coast Guard and literature references.
Several simple antennas that can be made in a Saturday afternoon with a bonus segment on NVIS (highly misunderstood). Lets build an antenna, throw it in a tree and go make QSO all in the same day.
Geared for expert hams and the newly licensed alike, this presentation provides an in-depth view about everything there is to know when it comes to working public service events, including parades, marathons, charity walks, bike rides and more. The discussion covers personnel and their duties, proper on-air and off-air etiquette and how participation in such events is great training for emergencies.
FORUM DESCRIPTION: You don’t have to be a Rocket Scientist to learn the basics of using your HT to talk thru the Amateur Satellites. The goal is to have you listen, track and transmit to the ISS cross-band repeater or SO-50 the next day.
An introductory presentation into the digital voice modes. When they started and how to get started yourself. Whether you have a local repeater or just plan to use a hotspot, it will be an introduction on how to decide which mode you want to start off with as you enter this very interesting and very viable mode of communication.
