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 improved and the repeater has been in service ever since. Coverage is by no means great, approximately a 2 mile radius around the Union. Great for campus use and not much else
Plans are in the works for a new 70cm TX/RX system at Hawkins to include all three W9YB 70cm machines and is expected to be completed by mid-2018
