History
Sometime in the 1980’s, Dave Chasey (then WN9NBT, now N9FN) secured the donation of a GE repeater for the club (firebottle vintage). It was re-crystalled for 444.500 (-) and installed in the elevator penthouse in the Hawkins Graduate house next to the 146.76 repeater. We are still digging through the club records to determine when it was installed and when it finally died.
The MSF10000 440 MHz repeater was donated by Motorola (along with the 2 meter repeater) in 1994. It took some time for the club to get the site and the machine properly configured, and it was put on the air in 1995.
A brief outage occurred in 2015 due to the common MSF “tin whisker” VCO failure mode. Thanks to N9DKI, the outage only lasted a semester and the club’s workhorse repeater was back on the air by 2016.
