I'm trying to use an ICOM F521 as a link repeater and interfacing it to an existing Kenwood TKR-750 site repeater and cannot seem to get the pinout below work. It would appear that the EPTT on the ICOM or Kenwood is not triggering.
Kenwood TKR-750 Icom F521 Pin 7(DG).............Pin 8(Mod. GND) Pin 9(TA).............Pin 2(AF OUT) Pin 11(RA)............Pin 4(Mod. IN) Pin 16(EPTT)..........Pin 5(PTT) Can anyone offer some help? John.
