2026-2027 RMHAM U classes will be announced soon. Yes, it’s really happening this year!
Please make sure you visit the menu above under RMHAM University, Sign Up For RMHAM University.
There’s no charge for our classes and everyone is welcome in person, or online.
Classes will be both in person at the (location to be announced soon!) but will but will also be simulcast on Zoom. Many of the classes are in the form of a lab, so we are looking forward to meeting in person. RMHAM University full length classes are scheduled from 8:30AM to Noon on the listed day. Once you sign up, you will have access to the zoom information in the registration system. You may ask questions via chat or via your microphone.
All of our courses are free to the public, but you will need to register to get the Zoom meeting information. To sign up, please click here
If you are here looking for RMHAM TECH TALKS, just use the sign-up link.
Any listed Tech Talk classes are 1 hour, from 7:30PM-8:30PM on the listed day. You may ask questions via chat or via your microphone.
Past video and presentations are available under Course Syllabus.

| 10/10/2026 | Gus Hansen, KB0YH | HF Antennas, Big and Small Getting started in any new activity can be daunting. In the amateur radio arena there are several barriers to be cleared before you can effectively participate. Obviously licensing is required, but you can become a listener before becoming legally qualified. In fact I highly recommend it. But even just listening requires some equipment and an antenna. Assuming you have either built or bought a receiver or transceiver, you will need an antenna. This session is about antennas that are suitable for high frequency (HF) operation in the 3 to 30 MHz range, but the principles apply to all available ham radio frequencies. The details vary based on frequency range, antenna size, deployment techniques, and the operating environment. The basics of radio propagation, antennas, and related topics are covered very well in the ARRL "Handbook" and "Antenna Book". Serious radio amateurs should eventually have both. In this session we'll ask whether to build or buy an antenna? I suggest you get started with simple wire antennas, usually horizontal, that are inexpensive, easy to build, and provide a great learning experience that establishes a good knowledge base. Also, self-supporting vertical antennas can be built at modest cost if you have some room for radials in or on the ground. If legal or other constraints force you to use small or hidden antennas, small transmitting loop (STL) antennas (often called magnetic loop antennas) provide a reasonable alternative worth considering. Gain antennas, such as Yagi-Uda, Log-Periodic Dipole Array (LPDA), and phased vertical arrays can provide a boost in performance over the simpler types. However, there is considerable increase in complexity and cost to be considered. | Sign Up |

| 12/12/2026 | Chris Keller, K0SWE | DMR Demystified: Theory, Codeplugs, and Practical Operation Digital Mobile Radio (DMR) has evolved from a commercial land-mobile standard into one of the most widely deployed digital voice technologies in amateur radio. This session demystifies DMR from the ground up, providing a clear explanation of 2-slot Time Division Multiple Access (TDMA) architecture, Talkgroups, Color Codes, Timeslots, and network routing. We will examine how local RF infrastructure (such as the RMHAM DMR network) routes traffic compared to global internet-linked systems like BrandMeister, giving you the knowledge needed to navigate the airwaves effectively without causing unintended network load. Moving beyond theory, this presentation focuses heavily on practical hardware and programming. While commercial radios from Motorola and Kenwood historically dominated the scene, modern amateur-friendly radios from AnyTone, TYT, Radioddity and even Baofeng have made DMR accessible, flexible, and feature-rich. Attendees will learn the building blocks of codeplug architecture, master Customer Programming Software (CPS) workflows, explore open-source firmware like OpenGD77, and learn practical troubleshooting techniques to get on the air with confidence. | Sign Up |
| 1/9/2027 | James Cizek, KI0KN | Batteries Chapter 2, Everything you ever wanted to know about batteries. This is a continuation of the first RMHAM-U batteries. This will focus on Lithium batteries. Charging and discharging nuances and the safety factors associated with them. | Sign Up |

| 3/13/2027 | Doug Sharp, K2AD | Remote Operating What is a remote Station? Where does the remote station magic happen? The IP connection between you (the remote operator) and the station (remote capable station) How are the RMHAM remote station(s) configured? Operating modes; how does one operate these modes Station accessories that might be at the station. How do I view and control? What is needed on the Remote Operator side to access the station? How can I get into trouble when operating the remote station? Live demo with several remote operator configurations. | Sign Up |
| 4/10/2027 | Bob Witte, K0NR | Exploring VHF/UHF Ham Radio All radio amateurs have access to the amateur spectrum above 50 MHz, so this presentation explores some of the fun things to do on these bands, beyond FM repeaters. This session covers the fundamentals of VHF/UHF ham radio including transceivers, antennas, transmission lines, types of modulation. The focus will be on the most commonly used bands (6m, 2m,1.25m, 70cm, and 23cm). We will discuss Summits On The Air, Parks On The Air, and VHF contests, all great operating opportunities. A major trend is the use of the WSJT-X modes (FT8, FT4, Q65), having a big impact on VHF/UHF operating. This session will include updates on recent topics, practical tips, and real-world experiences. | Sign Up |
