May 5, 2016 Club Meeting
Thursday, May 5, 2016 at 7:00 PM Red Cross Building, 60 Hawthorne St., Medford, OR (across from Hawthorne Park)
Program:
- How to make a slot antenna, Scott Cummings, NA7OM
- HSMM-Mesh on the Raspberry Pi: Can it replace the WRT54G for N1MM logging?, John Armstrong, KF7UMK
Scott Cummings, NA7OM, will show a slot antenna that he made. He will discuss the mechanical build of the antenna, and how to feed a slot with coaxial cable.
High Speed Multi Media (HSMM) was originally devised to run on the Linksys WRT54G series of WiFi access point / routers by re-flashing the firmware. Those old units are now starting to get tough to find. John will talk about HSMM on the Raspberry Pi, and application to computer logging.
Announced in the May 2016 issue of The Repeater.

Presentation
A presentation was given by John Armstrong, KF7UMK concerning mesh networks for N1MM Logging software. John discussed how the old WRT 54G router could be converted by reflashing the firmware. These units have been used quite successfully in the field.
Additionally, John presented the possibilities of the newer and more versatile Raspberry Pi 3 processor in the application of mesh networking. The Raspberry Pi utilizes Linux-based software allowing for expanded network programming, and the Pi 3 has built in WiFi and Bluetooth. Software is available at: https://github.com/urlgrey/hsmm-pi
