- KENWOOD TS-440
- ==============
-
- (Mods to permit all-band Tx and to add 10Hz digit to freq. readout)
-
- 1. Remove 17 screws holding on the bottom and top covers. The bottom cover
- comes off, and the top cover is carefully removed and put next to the
- radio. It is still connected via the speaker wire.
- 2. Gain access to the front of the unit by removing two top side screws and
- loosening two bottom side screws. This allows the front assembly to swing
- open.
- 3. Remove the shiny silver control board protection plate. This requires
- removing two screws on the top and three screws on the bottom. Lift the
- plate out completely.
- 4. Locate diode D-80 in the bottom left-hand corner. Snip it for all-band
- transmit.
- 5. Now locate D-66 and snip. It adds 10 Hertz readout to your digital
- frequency display.
- 6. Carefully reassemble the control plate using a magnetized tiny
- screwdriver to hold the five tiny screws in place. Don't pinch any wires.
- Also, close up the front and replace the top and bottom covers with 17
- screws.
- 7. Connect power. Depress A=B switch and turn on the power simultaneously.
- This resets the microprocessor for all-band transmit and 10 Hz frequency
- display.

- The article also tells how to increase the power of the TS-440 by adjusting
- the internal ALC control. The procedure is applicable to other rigs.
