Subject:Re:Standard C568A - TX Mod From:Larry Smith STANDARD C568 TX MOD Open the radio with care Remove the four screws at the back of the radio and remove the back remove 2 screws from the front of the metal plate at the bottom of the unit and open the front panel Be careful not to pull the ribbon connectors The logic board is on the back of the key pad There locate VR281 and VR265 above is a copper screen Remove the sub board located over the screen by gently pulling downwards. You then will have to lift back the copper screen lifting from the left side Follow a line up from directly in between the two VRs approx 5mm above mounted horizontaly is a 47k chip resistor Remove it Reassemble and do a full reset TX will now be activated wide band Due to the extreme miniturisation the job is not easy You will need an iron with a very small tip (battery powered) a good magnifying glass and 3 hands I take no responsibility for this mod Do it at your own risk However it worked fine on mine Larry G4OXY Source QRZ: The Windows Ham Radio CDROM
