Symptom: Low TX output on HF & 6-meters.
Probable Cause: Shorted D18 diode and Q1 transistor in filter unit.
Cure: Replace D18 diode (DAP222) and Q1 transistor (2SC4081).
--------------------------------------------------------------------------------
Symptom: Low mic gain.
Cure: Install field modification on main unit: Change value of R236 resistor from 27
k, to 68k-82 k.
The higher the resistor value, the greater increase in mic gain.

Symptom: Thin-sounding mic audio.
Cure: Install field mod inside HM-103 microphone: Remove rubber gasket from
beneath mic element.
--------------------------------------------------------------------------------
Symptom: Off frequency in FM TX. Other modes OK.
Probable Cause: FM VCO lock voltage needs adjustment.
Cure: Adjust FM VCO lock voltage for 1.5 volts as per service manual.
--------------------------------------------------------------------------------
Symptom: Unit is stuck in TX mode.
Probable Cause: Shorted T/R switching transistor.
Cure: Replace shorted Q32 transistor in main unit.
--------------------------------------------------------------------------------
Symptom: Radio won't power up.
Probable Cause: Burned ground circuit trace in flex cable.
Cure: Replace flex cable EP2 at main board.
