An overview of the M17 Project, including its purpose, current state, and futures.
Lessons learned while operating multiple 100 watt HF stations in close proximity.
I will talk about the recent RMHAM Winter Field Day operation operating SSB and CW simultaneously on the same HF band. Also operating two HF radios (on different HF bands) using the same Tri-band yagi. A quick look at HF Bandpass filters to determine what specifications are nice to have versus critical.
I will also discuss my work to design and build a 80/75 meter antenna system to be mounted on a QRV 50 foot mast. It is my hope that we can apply all these topics, and hopefully more!, at the RMHAM Field Day operation held on June 28-29, 2025.
We all have an assortment of collected test equipment for our workbench. There's so much equipment, some of it very heavy, that it tends to stay on our workbench. For portable use, or for a smaller workbench, why not use a USB Oscilloscope that can be much more?
A talk about techniques and station components to facilitate remote (or distant) operation of an HF station. In order for two HF stations to operate simultaneously on the same band, either extremely high-Q filters or physical separation is required.
High-Q filters are difficult and expensive to build. RMHAM can not justify the time and cost to develop these filters. To solve the problem, for example multiple stations at Field Day, we must work to add physical separation. Rather than have our operators walk five hundred feet across uneven and rugged terrain, we should bring the remote shack back to the Comm Trailer.
This talk will discuss some of the necessary station components that will be required to accomplish remote stations.
I recently upgraded from a two-door to a 4-door Jeep Wrangler because I needed more room to haul tools and equipment to work on radio sites. I removed my radios before the Jeep upgrade and was deciding if I wanted to re- install radios or go the simple and easy route and just use a handheld. I decided that I did want to install new radios in my new Jeep. I will present some of the considerations and goals of the install from deciding to “drill or not to drill”, final radios, antennas, power and ip networking. I will then talk about my planning for the install to include locations for the radios, control heads, microphones, antennas, batteries and various pieces and parts that needed to be ordered. Finally, I will talk about the progress on the install and lessons learned to this point.
Linking DMR and analog Allstar Link-based Radio systems using DVswitch software
ASL3 provides a number of new features. The talk discusses how these features integrate with ColMon.
