The Kenwood TS-940S is a serious radio for the serious operator. Superb interference reduction circuits and high dynamic range receiver combine with superior transmitter design to get your signal through. I got back to the Service Manual, and following the circuit diagram, checking the PC boards, I found a second. mistake: in the 2nd balanced mixer, in the IF unit, another inverted FET (Q4), harming the mixing/conversion, the gain, and the AGC performance. This picture shows the FET in the correct position. You can buy second hand TS-940 boards on EBay and elsewhere at very reasonable prices. With second hand boards and parts you can still obtain every component. Don't sell your TS-940 Repair it. If you like kits (or previously assembled Heath-kit radios), then you could say the TS-940 is like one large kit set, preassembled. This procedure allows modification to the control PCB (X53-1420-11) in the TS-940 WITHOUT having to remove the board. Remove the bottom cover and locate the control PCB. Locate R137 and R104. These are located in the upper right hand corner as the rig faces you upside down (near VR-3). A service manual is helpfull for locating parts!!!
