9:30 AM "Vacation DXing" presented by John Sweeney K9EL
Does the lure of DXing from an exotic location, in the comfort of a vacation home equipped with an upscale amateur radio station
appeal to you? John Sweeney, K9EL
, will tell us about some of his adventures such as to “FS” St. Martin in the Caribbean in 2013.
10:30AM "Alternative Power for Field Day and Other Temporary Stations" presented by Al Sawyer K9ILF
Come explore alternative energy sources from the global view down to the personal. See how you can get
started in grid independence for living, operating your station during power outages, assisting in
ARES operation at emergency sites, or just plain hands-on experience in powering your station.
Water, wind, sun and even human power can be used to generate electricity, but how much?
And what does it cost? This forum should help put this into perspective and generate ideas for useful
or fun ham projects.
On human power, see a demo of a bike-powered generator that Al Sawyer, K9ILF
, and a fellow
ham built for last year's field day. Al will share insights learned from the experience regarding
affordability, generators, and batteries.
11:30 AM "New Developments in HF/VHF/UHF Digital Voice Including FreeDV and System Fusion (C4FM)" presented by Warren Pugh KC9IL and Mark Thompson WB9QZB
1) HF and FreeDV:
Maybe you have already tried one of the Digital Voice modes on VHF/UHF, be it D-Star, P-25 or DMR (a.k.a. “MotoTrbo”).
But did you know that you can also experience similar noise-free communications on the HF bands? Digital voice
on the HF bands has been around for about a decade, but has really taken off recently with the introduction of FreeDV,
a software-based, sound card mode that can be used with just about any modern HF transceiver
(it works on VHF & UHF as well). If you are already using any sound card mode (RTTY, SSTV, PSK31, JT65, etc.)
you probably have most of the equipment you need to enjoy the latest development in Digital Voice for hams.
And, best of all, the software is FREE! Come listen to Warren Pugh, KC9IL
, as he describes the brief
history of Digital Voice on the HF ham bands, an overview of FreeDV and CODEC2, and provides a demonstration
of the FreeDV software, including tips for setting up your own HF Digital Voice station.
2) Amateur Radio VHF/UHF Digital Voice Modes Comparison and Introduction to Yaesu System Fusion
Amateur radio digital voice & data modes on VHF & UHF have experienced dramatic growth in usage over the
last 30 years. Starting with Packet Radio in the early-to-mid1980s continuing with APRS and over the last
few years with Winlink, D-STAR, P25 & DMR.
Mark Thompson, WB9QZB
, will review & compare the digital voice modes used in VHF/UHF ham radio including
amateur radio technologies: D-STAR & System Fusion and commercial technologies: APCO P25, DMR (MOTOTRBO) & NXDN.
He will also provide a brief overview of the new Yaesu System Fusion Voice & Data technology.
