The main repeater system is moved to AC4JF site.  For now only the 147.300 repeater will be operational.  The Monday night FM net will be conducted on 147.300.  The 145.21 repeater is still operational in the north Knoxville area. The 53.770 repeater is temporarily located at an east Knoxville location but has very poor coverage.  The Sunday night net will use only the 53.150 repeater starting Dec. 4.  The Sunday night will also have a USB session on 50.2 mhz starting around 9:20 and a AM session on 50.4 mhz starting around 9:40.

August 2015, the 444.575 and 145.21 repeaters have been upgraded to Yeasu Fusion analog/digital repeaters.  Therefore, 444.575 repeater is no longer linked to the other repeaters.  Users with Yeasu digital radios may operate these two repeaters in digital mode if desired.  If a user transmits in analog mode, the repeater switches back to analog mode.
