Edge of Space Sciences has scheduled EOSS-406, a high-altitude balloon flight carrying student experiments, for Saturday, October 17, from Deer Trail. The Rocky Mountain Chapter of the National Defense Industrial Association is sponsoring the flight, which EOSS describes as a single 1,500-gram balloon payload. Sunday, October 18, is listed as the alternate launch date.
The flight plan gives Colorado amateurs several ways to follow and support the operation. EOSS will hold a 7 p.m. Mountain preflight net the night before launch on the linked Fun Machine system, the EchoLink CANONCTY conference and TGIF DMR talkgroup 815. Denver-area RF options include the Mt. Thorodin, DIA, Westcreek and Devils Head UHF repeaters, with the Rocky Mountain Radio League and Denver Radio League repeaters named as backup paths.
On flight day, EOSS lists 446.050 MHz simplex for the launch site and 449.450 MHz on the RMRL repeater for tracking and recovery. Field teams have four additional UHF simplex channels—446.100, 446.150, 446.200 and 446.275 MHz—and may use Rocky Mountain Wide DMR talkgroup 700 or Central Colorado Regional talkgroup 720 when selected by the RF coordinator. Direction-finding frequencies are also published. The detailed plan makes this a useful listening and operating opportunity for Arkansas Valley hams, while giving student payload work a practical public-service communications component.
