In Feburary 2016, funds were pooled from the club account and several members’ wallets to acquire a Motorola Quantar being sold as surplus by a police department in Chicagoland. After a day trip to the city, the repeater was back at the union and sat until the duplexer cans could be acquired. After first attempting and failing to use a 3-cavity filter as a duplexer, the proper cans were obtained and tuned, and the repeater was put online using the club’s existing triband 6m-2m-70cm antenna on the top of the main tower.
The fall semester 2016 brought the mounting of a dedicated Laird 70cm vertical for the repeater, side-mounted to the tower at about 60ft above ground. The duplexer tuning was also improved. Coverage was still by no means great, approximately a 2 mile radius around the Union. Great for campus use and not much else
In winter of 2018, the Quantar was (finally) moved up to a permanent location at Hawkins Hall next to the other YB repeaters. Thanks to the efforts of several club members W3AXL, N9PCT, KD9FNA, and K5AN, the move was painless and the station was back on the air within a few hours. Additionally, hardware was acquired and programmed for future linking to the Indiana Quantar Network.
