Richmond Amateur Telecommunications Society

RATS hosts a secondary DMR repeater on the Brandmeister platform, operated by club member Jay Lovelady KD4BPZ.  This repeater is on 443.5375 MHz and is co-located with the W4RAT repeater system.  The antenna is at about 450 feet on the tower.  This repeater was relocated from downtown Richmond in December 2019 and flies the WA4FC call.

Before going on the air, repeater users should be familiar with the particulars of DMR operation, as well the RATS Repeater Rules & Policies, basic repeater etiquette, and some general talkgroup etiquette from our friends at DMRVA.  You must also transmit a valid DMR radio ID.  If you need help becoming familiar with DMR or have questions about operating procedures, please contact the RATS Technical Committee.  We will be happy to help in any way we can.

Questions about this repeater, including requests relating to nets or special events, should be directed to the repeater operator.

Time slot 1 is wide open for any talk group available on the Brandmeister network.  The activity timeout is set to 15 minutes on time slot 1.  You will hear no activity on time slot 1 unless a talk group is active, and a talk group will only remain active for 15 minutes after the last transmission through our repeater.  Talk groups in time slot 2 are always on.

Our DMR C-Bridge Repeater page has some helpful information about DMR talk groups.  Also, we found this really good comparison between Brandmeister and C-Bridge networks.

If you have a special need for extended access to a talk group, consider the use of a DMR hotspot device.  When selecting a talk group for a QSO, use the smallest talk group which will maintain contact with the desired station(s) and use the "clear time slot" function to disconnect from a dynamic talk group when you are finished using it.
