Clay Center 442.750 Update

May 8, 2020 – The GE Mastr II repeater that has served Clay County and surrounding areas since 2008 has been retired and replaced by a Harris Mastr III repeater. The new repeater operates in FM wide mode as the previous repeater did, but adds the capability of all common land mobile radio and amateur digital modes including DMR, NXDN, System Fusion, D-Star, and POCSAG paging. The digital capability is provided thanks to the amazing production work by Cort Buffington, N0MJS, who developed and produced the STM32-DVM-MASTR3 modem card that slides right into the Mastr III’s card cage.

This repeater is set to operate in FM and DMR modes, with the FM mode being linked to the K-Link network and the DMR mode linked into the KS-DMR network.

Users of this repeater may hear the digital modulation when there are active DMR calls. To silence this, you will need to program your radios with TSQ (tone squelch) set to 162.2 so you can continue to hear FM traffic without being bothered by the digital “noise”. We encourage people to utilize the DMR mode and take advantage of it’s superior audio characteristics.
