Saturday 9:30 AM: *Digital HF Voice In Half the Bandwidth of SSB! Codec2-HF *The new Codec2-HF application provides existing SSB rigs with a new mode: digital voice in 1.1 KHz, half of the bandwidth of SSB! Because it's not a secret algorithm like other codecs, it's fully legal for communications between all nations.
Learn how to work other Amateurs on digital voice, using a Windows, Mac, or Linux system. Take home the free application!
Hear about how hams took over the lead in digital voice development, advancing the state of the art significantly over existing commercial digital radio systems.
Saturday 10:45 AM: *HAM WiFi on 432, 900, and 5 GHz *WiFi-like systems can be used for Amateur digital networking, and commercial hardware is available for several bands. Most of these systems take a 2.4 GHz WiFi signal and convert it to another band on the wifi card: 432, 900, or 5 GHz hardware is in use by hams. But setting up these networks is difficult: the hundreds-of-mile distances shown in experiments are between mountaintops over desert, and real-world performance is much worse. A 1/4 mile limit can be expected between mobiles with omni whip antennas, but permanent high-speed digital links of 10 miles between fixed stations are possible, given line-of-sight and a good outdoor installation. Fresnel Zones limit the performance of low-height antennas, and other tenants on shared bands interfere.
Learn about building real-world systems, including calculating if a link can work between two points, hardware and software available for building these systems, the various router boards, Mini-PCI cards for different bands, software distributions like OpenWRT, weatherproofing, two forms of power-over-ethernet, and antennas.
Saturday 1 PM: *Amateur Emergency Services and Confidentiality*Hospitals and other health-oriented emergency services clients have grown wary of using Amateur Radio for emergency communications since the passage of HIPPA, which requires patient confidentiality.
But confidentiality and Amateur Radio are incompatible - FCC rules, and those of other nations, prevent us from obscuring the meaning of communications. And the shared nature of Amateur frequencies means that encryption of Amateur communications isn't appropriate, and never will be. How can we keep from losing our emergency services function while also keeping true to the nature of Amateur Radio?
This talk explores the nature of patient information that might be carried over Amateur radio in an emergency, the conflicting rules regarding that communication, and potential solutions.
Thanks
Bruce
