Echolink Repeater Broadcast Message #dvs


Good afternoon, on Windows PC running Echolink in SysOp mode I can run a pre-recorded hourly message (.wav file) on an Echolink repeater, for hours have been trying to do same on my RPi4 running Allstar and Echolink bridge on DVSwitch, has anyone ever done this and if so are there any instructions please, many thanks in advance.
