Episode 155: Belton HamExpo, Fall 2018

The Belton HamExpo, held twice a year in the small town of Belton, TX, is one of my favorite Hamfests of the year – it is centrally located to several large metroplexes in Texas, and it is held in a facility that has a fantastic parking lot, suitable for outdoor tailgating. The official show is 7am-Noon on Saturday, but people arrive late Thursday evening to setup outside in the parking lot for the unofficial swap fest on Friday.

Episode 154: The 2017 Eclipse Multi-Site DMR System

The 2017 Eclipse Multi-Site DMR System


Mike Pappas, W9CN, with EOSS, talks about deploying a multi-site DMR system for the 2017 Total Eclipse of the

Sun. This was a very interesting talk to me, because it deals with setting up an IPSC DMR system and demonstrates how usable and reliable this type of setup can be for these deployments.

Episode 153: Understanding DMR Networks

Understanding DMR Networks

Understanding DMR Networks, from the 2018 TAPR Digital Communications Conference.
In this episode, I present a topic that details differences between a CBridge Network and the Brandmeister network for DMR Repeaters and users.

My main reason for putting together this information is that most of what I have read on Facebook or other websites about CBridges is wrong.  I maintain my own CBridge at CBridge.hamradio2.com and I learned quite a bit about the inner-workings of these systems while setting up and maintaining this network.  I decided to create a presentation and share this information, and I am grateful to the folks at the TAPR Digital Communications Conference for allowing me to present this information.

Episode 152: TAPR DCC 2018 – The Real FT8, JT65, and JT9 Signal-to-Noise Ratio Revealed

Signal-to-Noise Ratio for JT65, JT9 and FT8

Measuring the Signal-to-Noise Ratio for some of the most common HF Digital modes can be confusing.  In this presentation at the TAPR Digital Communications Conference, KC5RUO gives us an analysis of comparative signal-to-noise ratio measurements, what they mean, and how to use them.

Episode 151 – Evaluating 9 of the Best Single Board Computers for Modern SDR Systems

2018 TAPR Digital Communications Conference

From the 2018 TAPR Digital Communications Conference, Scotty Cowling, WA2DFI, presents his findings (after LOTS of research) of which SBCs are best for a custom SDR setup.

Among the most common SBCs is the Raspberry Pi, but is it the only solution?  Or the best solution?  Check this forum from the TAPR DCC and learn some alternative solutions for building a modern SDR Receiver or Transceiver.
