I have a Motorola MTR 2000 repeater. I have an ICS Controller board in the J5 system connector, going to a URIxB via the DB-9 to DB-25, assembled by me. I've done days worth of research to no avail. The repeater & URI both show TX if I key the radio in the simple_usb_tune menu. Hitting the repeater with a HT, RX lights up but no TX on the URI or MTR. Not sure if this is RSS programming or on the URI/Asterisk side. Any suggestions would be greatly appreciated. Thank you all!
