IC-7000 Modifications

This information is for educational purposes ONLY This is a Reversible modification.

Do NOT use this modification if you are using this unit mobile. It is against the law in most jurisdictions to have TV reception where the driver may see the screen.

DO use this as a BASE MODIFICATION ONLY.

TV Reception:

1. Remove the top cover of the unit. (There are only 8 screws holding the cover in place, do NOT remove the four screws surrounding the speaker.)

2. Gently unplug the speaker wire and set the top to the side.

3. Gently lift the "Tuner Control Socket" and lift out of the way.

4. Remove DSP unit by unscrewing two silver screws holding it down. (The silver box on the top of the radio under the cover, with copper taped sides) One of the screws was under the tuner socket control wires. Pull the unit straight up.

5. Almost directly in the middle towards the front of where the DSP plugs is a Solder jumper. It is the ONLY solder jumper on the board.

6. Remove that jumper with wick or sucker. (DO NOT REMOVE DIODES AS IN OTHER DIRECTIONS.)

7. Reassemble in reverse order.

8. With a new unit it enable reception automatically. (If you have already placed anything in memory anywhere, do a CPU reset. BAND UP and BAND DOWN while turning the unit on.)

9. To make the TV work just hold the SET (AF control.) momentarily. Switch off the same manner.)

10. To change channels just rotate the tuning knob. The channels are built in memorized.

TVRO:

1. Lift off the the top half of the radio case, after removing its securing screws.
2. Refer to Figure 1. Remove CPU/DSP unit by unscrewing two silver screws holding it down (the silver box on the top of the radio with copper taped sides) and pulling the unit up. (The screws are ringed in white.)
3. Locate four shift registers and bank of diodes - shift registers are 4094's. There are two next to each other and then a couple more. We'll call the two stacked the "left" ones.
4. The "middle" shift register if looking from the front of the radio is the target.
5. Locate bank of SMT diodes (silver with "K" on top on one side) in front of the target shift register. They are in two columns, "left" and "right".
6. Unsolder one side of the second diode from the front on the left and lift up one side (or remove, slip to the side, whatever you are comfortable with.)

    Please observe local traffic laws concerning use of a TV set in a vehicle!

MARS/CAP:

Here is an out-of-band mod which allows transmitting from 0-54, 118-173 and 400-470 MHz. (Please observe radio regulations!)

1. Remove CPU/DSP unit by unscrewing two silver screws holding it down (the silver box on the top of the radio with copper taped sides) and pull up. The screws are ringed in white (see Figure 1).
2. Locate four shift registers and bank of diodes - shift registers are 4094's. There are two next to each other and then a couple more. We'll call the two stacked the "left" ones.
3. The "left" shift register if looking from the front of the radio is the target.
4. Locate bank of SMT diodes (silver with "K" on top on one side) in front of the target shift register. They are in two columns, "left" and "right"
5. Unsolder one side of the second diode from the front on the left and lift up one side (or remove, slip to the side, whatever you are comfortable with.)
6. Note: After the modification has been performed, the "Band Edge Beep" feature will no longer function, even if it has been enabled.

NOTE: The Automatic Repeater Shift on 2 meters and 440 is not affected by this mod
