In April 2020, the Dave Fish, WB0NTZ, and Gary Harrison, K0BC, approached the club about the Lakes Area Radio Association (LARA) dissolving and asked the Nixa Amateur Radio Club if they would be interested in taking over the repeaters and maintaining them for the amateurs to continue using in the region.  On August 5, 2020, Nixa Club President Shawn Roesslet, KE0JGI, accepted the ownership change with the Missouri Repeater Council.

When the exchange took place, the repeater was a 25-W Motorola XPR-8300 with a DB-224A antenna for public safety use with LDF4-50 1/2" heliax.  The antenna system was adequate but didn't have a good return loss down at 145.290.  The club was also taking over operation of the 147.060 and 443.675 repeaters at this site and needed to replace the coax and antenna or the 147.060.  A plea went out to amateurs throughout the region and generous cash donations came in to help rebuild the systems.   The donations were used in conjunction with the funds the LARA had left in their savings account to purchase the new antennas in January 2022.  To raise the funds to pay for the installation,  the club sold about 600' of AVA5-50 that had been donated to the club for the Queen City Digital Project.  In addition, a 100w primary and a 40w backup Tait T800 Series II repeater was sold to Bill Whetstone, KB8VLL, to replace the 146.670 in El Dorado Springs and a 100w primary repeater and 40w backup T800 Series II repeater was also sold to the Aurora club to replace the W0OAR 146.970 repeater.  James Adkins, KB0NHX, worked with these clubs to program and tune the repeaters and add external controllers to them greatly helping their group's repeater systems. 

In August 2022, A&W Communications installed the new Comprod 872F-70TM-1/4 antenna and 7/8" heliax and the 25-W Motorola XPR-8300 DMR repeater was replaced with a 50-W Motorola SLR-5700 DMR repeater
