The 146.985 repeater came online June 3, 2020.  In May 2019, the Missouri Hospital Association purchased the antennas for this repeater along with the 146.820 and 444.775 repeaters on a grant requested by Bill Brashears, N0WCB (formerly KD0STZ).  Getting the antennas donated was a huge hurdle to overcome.  Coax cable for all repeaters had already been donated by Commscope so the only remaining hurdle was paying for the installation of the antennas and coax - $1,875.00 for the Rolla site alone!  Using funds made from the NARCfest hamfest, excess heliax cable sale, a Yaesu FT-450 raffle, and a $3,000 donation from the Community Foundation of the Ozarks, secured by Larry Grinstead, WA0JZK, the funds for the Eastern Expansion labor could move forward.

In early 2021, as part of a club initiative, Todd Christell, AD0RR, replaced all the electrolytic capacitors in this MSF-5000 repeater as well as all others owned by the club.

In March 2026, James Adkins, KB0NHX, and Eric Presser, KD0CEN, replaced the Motorola MSF-5000 with a mixed mode Motorola Quantar repeater capable of P25 digital for local operations or analog use for communicating on the Southwest Missouri Linked Repeater System.
