Pre-Net: 6:00-7:00 PM

Presentation: 7:20 – 8:30

In the early days of Amateur Packet Radio and APRS, it was necessary to use an expensive “Terminal Node Controller” (TNC) with specialized hardware. Those days are gone. You can now get better results, at lower cost, by connecting your radio to the “soundcard” interface of a computer and using software in place of the traditional TNC.

Dire Wolf is a software “soundcard” AX.25 packet modem/TNC and APRS encoder/decoder. It can be used stand-alone to observe APRS traffic, as a tracker, digipeater, APRStt gateway, or Internet Gateway (IGate)

We are starting this disussion on APRS as the club has identified a goal of improving our APRS installation. This will further leverage our existing investment in full time high speed internet access. The club’s current APRS setup is a digipeater with a traditional TNC. We are in a great location and can serve the APRS community well to add in iGate functionality.

Antenna Analyzer Techniques presentation now available

The October 28th meeting’s presentation is now available on YouTube.

Greg Algieri WA1JXR is the presenter. The presentation is an Introduction of Principals, Techniques, and How to Use the popular MFJ 259B Antenna Analyzer and the SDR-Kits Vector Network Analyzer. How they Work, What is inside Under the Hood, and what are some of the things you can do with them.

Note: The recording missed the first part of the discussion on the 258B. However a lot of techniques discussed with the SDR-Kits apply regardless of analyzer brand.
