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...

4. Introduction to the Digilent Analog Discovery 2 and 3, Test Equipment For Your Bench

Dave Maciorowski

2/15/25, 9:30 AM

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?

6. Considerations for a remotely contrtolled and operated station

Doug Sharp (RMHAM)

2/15/25, 10:00 AM

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,...

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...
