I was talking to Rob, G4XUT yesterday about getting the case of an Ascom SE-550 open - in order to make some adjustments to the internal squelch pot.Rob very kindly put together a list of instructions on how to get the rig apart which I thought someone else might find of use. Thanks Rob!To get into the Ascom:-Assuming that the mobile bracket has already been removed.Disconnect the rear connector by loosening the retaining screw.Remove the Mic plug connector.Unplug the code plug which is above the mic connector.Remove the screw behind code plug.Detach the front panel with is hinged on the L/H side.Remove the 4 screws at the front and 4 screws at the rear.Carefully pull apart the two main boards from the main housing.Carefully re-assemble the two boards.Replace the front panel, code plug and the mic plug.Power up and adjust sq or whatever as required. Simples!!
