FT-840 modification for out-of-band transmission

Want to make your radio do more than what it came with out of the box? Or are you running a transverter and want to get complete band coverage? This mod will
reprogram the Yaesu FT840 ham rig to transmit from 1.8-30 mHz with NO GAPS. It doesn't require any desoldering, diode snipping or clipping, or even any
rewiring (other than a temporary ground jump), and can be done by anyone with a basic knowledge of electronics.
Tools Required:
1 Set of small alligator-clip jumper leads (Radio Shack, RS# 278-1157)
1 Small Phillips head screwdriver
Time: 15 minutes
Difficulty: Easy

1. Remove antenna from radio and disconnect power supply.
2. Remove top and bottom covers.
3. Jump test point TP-2003 to ground. (Take a wire lead + attach to the metal case)
4. Press & Hold (SSB) + (AM) and turn power on. (Display will show 02-OFF)
5. Rotate main control to show 02-ON
6. Press AM. The display should read (7.000.00 LSB)
7. Turn radio OFF.
8. Press and hold the memory (DOWN) + (UP) buttons and turn radio ON.
9. Turn the radio OFF.
10. Remove the jumper to ground on TP-2003.
11. Reassemble radio.
12. Reconnect antenna and power supply.
TP-2003 is a small pin next to the round backup battery. You have to remove both the top and bottom covers, even though the pin itself is on the bottom side of
the chassis. Remove the top cover first; it locks itself into the bottom cover. You don't need to disconnect the speaker leads going into the top-mounted speaker.
