I saw many requests for this mod but never had a chance to post it till now.
Yaesu FT-840 Expanded RF
All band modification:
1. Remove bottom cover and locate vertical pin TP 2003.
2. Connect a jumper wire from this pin to ground.
3. Hold SSB button and AM button at the same time and turn the radio On.
4. Frequency display should read "02 OFF". Turn Frequency knob until display
reads "02 ON". Now turn radio Off.
5. Hold VFO/M button and UP and DOWN buttons at the same time and turn the
radio On.
6. Last, turn radio Off and remove jumper from Test Point 2003.
7. Reassemble radio.
This mod allows gerneral coverage transmit on the FT-840.
I assume no responsibility, proceed at your own risk.
