About Carprog Antenna Fix:
replaced 150k with 15k (resistor)
2+3+4 here we need to solder a capacitor with aproximately 6-7 nF(put one or combine from 2-3 capacitors)
removed 100 nF capacitor
removed 100 pF capacitor
in position 2 it was a 2.8nF capacitor
in pos 3 it was 0.5 nF cap
in pos 4 it was 100 nF cap
YOU SHOULD HOLD RESPONSIBILITY OF WHAT YOU WILL TRY.
GOOD LUCK!!!!!!
If you fail or nothing work, go for another Carprog 8.21 with a good PCB:
