OF NECESSITY THIS MEANS THAT THE FRONT AND REAR PANEL COMPONENTS ARE NOT DRAWN TOGETHER (AS ON THE ORIGINAL) BUT ARE DRAWN WHERE REQUIRED - I'M SURE YOU CAN FIGURE OUT WHERE THEY ARE :-) THE POWER SUPPLY SECTION ON THE ORIGINAL WAS DREADFUL, AND HOPEFULLY IS NOW DRAWN SO THAT IT IS EASILY UNDERSTANDABLE. ANY SUGGESTIONS FOR IMPROVEMENTS OR CORRECTIONS OF ERRORS SHOULD BE ADDRESSED TO ME AT THE EMAIL ADDRESS GIVEN IN THE TITLE BLOCK AT THE BOTTOM RIGHT HAND CORNER.

THIS SHOULD BE SHORTED OUT TO GET BETTER SQUELCH ACTION *2 ON CHASSIS WITH METERS (MUSTANGS, TRANSCOM etc), D13 IS FITTED IN PLACE OF THE WIRE LINK NEXT TO T11. THESE RADIOS REALLY NEED AT LEAST ONE MORE DIODE IN SERIES IN ORDER TO REDUCE THE READING ON THE METER TO ZERO FOR NO SIGNAL INPUT.
