WOUXUN KG-UVD1 modulation MOD

Makes modulation more brighter and louder.

1. Disassemble radio removing antenna, volume and encoder knobs and unscrewing two

HEX-nuts at the back bottom of radio.

2. Pull out whole frame using flat screwdriver from the bottom side. Don’t forget to detach

protective rubber cover of MIC/SPEAKER jacks first.

3. Temporary remove protective tape from the PCB:

4. Cut or unsolder small SMD mic blocking capacitor:

5. Apply back protective tape to its original place.

6. On the right (main) PCB locate small trimmer above the «MOD» testpoint:

7. Adjust deviation according to your needs. I recommend to set MAX deviation (turn the

trimmer counterclockwise until modulation disappears, than turn back a little bit to catch

maximum deviation position).

NOTE: Don’t forget to attach antenna or dummy load to the

Antenna jack otherwise you can burn the finals of the radio

during transmission, especially if your Power option is set to

High.

8. Locate and remove (cut or unsolder) small SMD blocking capacitor in the first stage of

mic preamp filter:

9. Locate and remove mic blocking capacitor below the external MIC/SPEAKER jacks:

10. Reassemble the radio.

Now you’ll have more brighter and louder transmitting audio with more highs accented.

NOTE: I’ll take no responsibility for any loss or damages to

your equipment if you apply this mod. Please remember that

you’ll also loose warranty for your radio if you decide to apply

any modification of internal components / adjustments.

With best regards,
