The schematics for the radio come with the radio. J27 is by the ground screw of the radio. If you remove the top cover of the radio and look at the rear by the ground screw you will see silkscreened on the board J27 and a diagram showing which setting is TXREQ and which is TXGND.

can you supply pic of schematics

Tks. if you modify the jumpers like this
O= Open
C= Closed(Shorted/jumped)
3 2 1 6 5 4 9 8 7
O O O C O O C C C
reset radio:
hold in [F]+[V/M] and turn on the radio
you will get full tx

1.8MHz to 56MHz
137MHz to 164MHz
420MHz to 470MHz

I have done this mod on my ft-897D and on my FT-817nd works great.

Tks.
