    They should actually be 0 ohm resistors. I just used solder bridges when I did mine and haven't had any issues with it.

    Make sure your solder tip is clean and real pointy..a magnifying glass might come in handy

    The biggest issue all these years in the future is you STILL LOSE the band edge markers with mods like this

    I can think of several ways to recreate the band edges for at least scanning purposes if nothing else. Still it is the only way to get 60m .
    You would think that anyone that knows enough to purchase an 857 on purpose and actually knows how it works without bitching about band edges ....

    Thank you guys for sharing your experience with this mod, I would love to know what you guys think about this:

    The previous owner of my 897D had MARS mod on and decided to remove it before selling it to me. I believe he damaged the JP1007 irreversibly .
    I'd like to show you the attached picture.
    The soldering pod of the left side of the jumper looks completely missing, and I am not sure if soldering on top of that will work to restore the mod.

    I wanted to know what your take on this is....
    any help is much appreciated!!
    Cheers
