Remove the 6 screws holding the Main Board to the chassis and carefully lift the front edge of the Main Board up and lay the board back onto the transmitter's heat sink.To release the ribbon cable from the connector, use a pointed tool to push forward the locking tabs located at each end of the connector. Disconnect the ribbon cable that goes into the front of the Main Board.Disconnect the two coax cables (J3 and J4) near the front of the Main Board.Remove the two spring clips that secure the two ICs (IC11 and IC20) to the chassis on the left side of the unit.

Pull up and remove the small PC board (Connector Unit) that the front-panel cables attach to.

Remove the two screws securing the front bottom rail, and remove the rail by pulling it forward to disconnect the connector that is located near the microphone connector.

Remove the two screws securing the front top rail, and remove the top rail.

Lift the speaker and bracket up and away (and you can disconnect it at the PC board connector if you want to get it out of your way).

Remove the two screws securing the speaker bracket.

The blank plate then snaps off the upper and lower front chassis rails. Remove one screw holding the blank plate to the front of the chassis.

Remove the radio's top cover (5 screws) and the bottom cover (7 screws).

Note the way the cables are routed through the plastic blank plate on the front of the radio.

With DC power removed from the unit, remove the front panel and disconnect the two connectors from the front panel.

If you are not comfortable with working with very small surface-mount components, refer the task to someone who is. While this is not a particularly difficult task, it does require some skill with working with surface-mount components and PC boards. Perhaps a 10 k, 0603 resistor, 5%, depending on your radio.Д¬AUTION: This modification involves raising up a printed circuit board and replacing one or two small 0603-size components. While I'd like to see still better performance from the NB, this appears to be about the best I could do with only minor changes to the circuitry.Д .039 uF capacitor, 0603 size (or a 0805-size part can be made to work).

This mod takes the NB from being virtually worthless to being at least somewhat useable on impulse noise from ignition systems and power-lines. These components are located on the backside of the Main Board, which is the PC board located under the unit's top cover. It is also necessary to verify the value of R392 to ensure the correct NB time constant exists. This mod allows the noise blanker to attack more quickly on noise pulses and it also reduces the duration of the blanking action. Unfortunately, Alinco is unable to offer a remedy for the problem.ДЄ noticeable improvement can be made to the noise blanker by changing the value of C324 on the Main Board to a smaller value. Like other DX-70 users, I've found that the NB virtually destroys the desired signal, especially if the noise source is ignition noise from an engine operating at normal highway RPMs. I have to agree-the NB performance is pathetic. Perhaps the most common complaint among Alinco DX-70 users has to do with the poor performance of the noise blanker (NB).
