IC-7000 Modifying to receive PAL TV


Modifying the Icom IC-7000 Export version No 8 to receive PAL TV in South Africa and to open up the TX frequency range.

In South Africa the TV audio frequency is different to that used in other parts of the world. We use 6 MHz instead of 5.5 MHz as used in the Icom IC 7000 export #8.

The ceramic trap filters have to be replaced. They are situated at the bottom of the Main Board. This board needs to be completely taken out of the radio then obviously replaced once the new filters have been fitted.

The shift register diodes need to be changed in order to open up the frequency range and enable the television tuner. A number of diodes are removed and one diode installed where no diode originally existed.


  • 1.  Remove the top cover of the radio and unclip the speaker plug.
  • 2.  Remove the CPU/Logic unit. (Silver box)
  • 3.  Remove the DDS unit.
  • 4.  Remove all coaxial plugs and ribbon cables from the board. Be extremely careful when removing the two ribbon cables at the front of the radio as they can be pulled out of the PA unit. It is extremely difficult to reinsert them into the PA unit.
  • 5.  Remove the spring clip at the back of the Main board holding IC 2602 to the chassis.
  • 6.  Remove the Main Unit – This is the unit to be modified.
  • 7.  Remove the two SMD ceramic trap filters situated underneath the board as seen from the top view.
  • 8.  Replace old filters with 6 MHz ceramic trap filters obtainable from any TV repair shop. Cost R8.00 each.
  • 9.  Remove shift register diodes. Fit one diode at right hand side of the board as viewed from the front of the radio looking towards the back, orientating it with the cathode to the left.
  • 10.  Plug in the two ribbon cables from the DDS unit into the Main board before fitting the Main board to the chassis.
  • 11.  Replace all screws and tighten.
  • 12.  Plug in all the cables, re-fit the CPU/Logic unit etc.
  • 13.  Replace the top cover. Don’t forget to plug in the speaker.
