    I hope someone reads this post that can help me out.
    I need to remove the speech processor board, PB1534, from a Yaesu FT-101EE.
    The board has some issues that I am not going to chase and just want to remove it completely. It is a simple procedure to remove it, BUT .......
    After the harness wires are disconnected from the board, I do know that some of the harness wires need to be soldered together and the the ends covered with shrink tubing.
    Problem is that I have not found any instructions anywhere to tell me which wires to connect and solder. The schematic is no help. It does not show the state of the wiring before a processor board is installed.
    If anyone has a FT-101EE and would be willing and kind enough to to remove the top cover, remove the black tubing from the wire harness bundles, and take a couple of detailed photos and description of which pairs or wires to mate together, I would be very grateful.
    I don't want to get into a discussion about chasing down the board problems, or repairing it.
    I just need to remove it altogether from the radio.
    Thanks for any help anyone can provide.

    I've replied to an identical Post in the Boat Anchor section . . .

    (maybe a Mod will delete this one)
