I have talked with Repeater Builder and was advised that both COS and CTCSS jumpers should be set to active LOW in the RC-210. My question is in regard to the DTMF settings; should this be enabled with the RCP programming or mute DTMF in the RC-210 and let the rpt.conf handle it. James, KM7KK -- T KM7KK.com .- .-.
