Effective operation of amateur radio repeaters, particularly in high-density areas, relies on coordinated frequency assignments to prevent interference. This resource from the _Illinois Repeater Association_ (IRA) serves as the official frequency coordination body for the state of Illinois, providing essential information for repeater owners and users. It details coordination policies, guidelines, and application forms for new and existing repeaters, ensuring fair and consistent spectrum utilization. The site also includes a comprehensive band plan, last revised in 2006, and a selective access policy (PL/Squelch Plan) updated in 2015, which are critical for maintaining orderly operations. The IRA website offers various repeater directories, sortable by frequency, city, and region, including a dedicated section for digital systems. These directories are invaluable for hams traveling through Illinois or setting up new repeater projects, helping them identify available frequencies and coordinated systems. The resource also provides meeting minutes, newsletters, and links to other regional repeater councils, demonstrating its role in fostering inter-state coordination. This structured approach to frequency management helps ensure reliable communications and minimizes QRM across the state, supporting thousands of repeater contacts annually.

High Speed Multimedia (HSMM) radio, as introduced by John Champa, K8OCL, represents a significant advancement in amateur radio's digital capabilities, moving beyond traditional keyboard modes like packet radio. This initiative, driven by ARRL's Technology Task Force, focuses on developing high-speed digital radio networks capable of up to 20 megabits per second. HSMM primarily facilitates digital voice (DV) and digital video (ADV), enabling real-time video transmission from emergency scenes to an EOC without expensive ATV gear, often requiring only a laptop, a PCMCIA card, a digital camera, and a small antenna. The working group's initial efforts concentrate on cultivating microwave skills within the amateur community to build and support portable and fixed high-speed radio-based local networking, or **RLANs**. These networks prove invaluable for RACES and ARES organizations, as well as homeland security and other emergency communications. Field Day exercises and simulated emergency tests (SETs) are encouraged to hone skills in rapid site surveys and deploying broadband HSMM microwave radio networks, with examples like linking Field Day logging stations or antenna test results at the Midwest VHF-UHF Society Picnic 2003. Getting started with HSMM often involves adapting off-the-shelf **IEEE 802.11** (WiFi) equipment to comply with amateur radio regulations, typically operating in the 2.4 GHz ISM bands. While consumer WiFi gear has range limitations under Part 15 rules, proper setup under amateur regulations can extend coverage significantly, with test networks like the Hinternet achieving 5-15 mile ranges at 54 M bit/s using small mast-mounted dish antennas. Careful selection of equipment with external antenna ports, high transmit power, and low receive sensitivity is crucial, along with using low-loss coaxial cable like LMR-400 for optimal performance at these frequencies.
