On January 21, 2025, dozens of stations across northeast Illinois gathered for a 70-centimeter simplex research event. The goal was to encourage simplex use, to expand operator skills, and to allow operators to better understand their station’s capabilities and limitations. The operation involved two rounds of transmissions, and collectively logged over 400 signal reports, received by email and aggregated by Net Control. Operators freed themselves from repeaters and access tones, and learned to relay, record RST (readability-signal strength-tone) signal reports, and pay attention to their noise floor and antenna configuration. One relay through four stations spanned nearly 60 miles, allowing net control — K9MSG in Glen Ellyn, Illinois — to receive a message from KE9BPO in Sandwich, Illinois, operating on a handheld at 5 watts. After the event, all logs were collected and aggregated, and each station received a report that included details of all signal reports given for their station by all other operators. The report also included maps, statistics, and examples of how to leverage the data to better understand station configuration. This included a subsequent discussion on how to create radio path studies leveraging free online resources. This was the 2nd of two such events. The first was a 2-meter simplex activity in the same area the prior month with 35 stations across 7 counties. Data from both of these nets is now being aggregated to identify quantitative and qualitative differences between 2 meters and 70 centimeters as experienced by those operators. All of this will lead to a discussion of the propagation challenges and advantages that each band offers and more opportunities for learning!
