It was tested twice, and then stored long term at the Jerome Sears Center. Over that period, institutional knowledge on how to use the repeater was significantly diminished. A family of squirrels also took up living in the mast bag and they ate one of the instruction manuals. The repeater was moved to volunteer care in 2024 after PBEM was booted from Sears and the repeater was finally tested again in April 2025.. | ||
