D-808 Schematic — Xhdata

Replacing the stock internal MW ferrite antenna with a larger, higher-permeability rod can drastically improve daytime Medium Wave DXing. Conclusion

Static electricity from an external wire antenna can easily blow these ESD diodes, shorting the incoming RF signal directly to the ground line. Replacing these small SMD diodes restores performance. Issue 3: Encoder Skipping or Erratic Tuning xhdata d-808 schematic
