[App_rpt-users] Kerchunk filter or equivalent of pulseback timer?

Hi All; One of the local repeaters is connecting to the VE3TNK HUB (#2200) using an off-site link radio (since there's no IP at the repeater site). Unfortunately, the analog repeater controller can not be set for zero hang time, and therefore the short hang time is being exposed to the hub and all of the downstream nodes. Is there a kerchunk filter or the equivalent of a pulseback timer (as there is in IRLP) to compensate (filter out) such kerchunks? Thanks! Ramesh.
