    --Hi, all. I own a Yaesu FT-857D that already has the 60 meter channels built in and was wondering how I can add the upcoming frequency of 5357? I think the change to the 60 meter band will come in March and I want to be ready.

    --I emailed Yaesu yesterday regarding this and they have already given me a response. I (in a nutshell) asked them if there was an approved modification to get this new 60 meter frequency. The answer given was this: "Adam:
    At this time Yaesu has not announced any plans to change the existing
    60-meter feature on our radios.

    Thank you for your interest in and support of Yaesu Amateur Radio products."

    --I see a "MARS mod of the FT-857" on the mods.dk site, but it says nothing about whether or not the mod is compatible with the "D" model, which mine is. Also, the mod is dated June, 2003, and I bought this radio from the dealer about a year and a half ago. I was just needing from Yaesu, an "approved" mod to get this upcoming new frequency, but gave me an answer that didn't quite answer my question, lol. Thanks for any help!

    Thanks for the help. Was it difficult to add the three jumpers to the JP1007/1008/1009 locations? The jumpers look tiny to me, lol.

    "adding jumpers" is just dragging your soldering iron across the 2 pads to make a soldier bridge. nothing to it. write down your settings for mic gain etc before you do the reset, if you dont want to lose it.

    Thanks. Yeah, looking at the picture, it looks easy enough to just drag a bit of the solder like you said. Glad to know this will be easier than I thought.

    If you are worried about goofing up the solder job you could probably use one of those conductive trace repair pens.

    this is just an example if you look around you can probably find it or a similar brand cheaper.

    Don't forget to do the master reset after the mod.

    --Well, it looks like I won't be doing this mod. I just got finished opening the covers to the radio and found the row that is supposed to contain the jumpers. Looking at it (with a magnifying glass) there are only TWO on the whole row at positions "1" and "2"...all the other positions are blank. Not only will I not get the new 60 meter frequency, but the other frequency they are moving, means my radio will only have three valid 60 meter frequencies instead of five (when it's available in March, I mean). Oh well.

    if you do the mod just remember what settings you have now,
    mine did not match the before picture either,
    I followed the jumpers in the mod. instructions and it worked just fine,
    I also played a bit and tried a few other settings of the jumpers and they did "other" things,
    so I say do ahead and try it, you can always change it back and reset again
    and then set up a few memories with the new frequencies

    there is also a software package that changes the jumper settings, but if you ever reset it fully it goes back,
    I found that software on a yahoo group for the 897 and it applies to the 957 as well
    the software advantage is that you don't have to solder anything.
    if you can't find it and want the software, say so and I will get it to you somehow.

    huh? put jumper at 1007, 1008, 1009 and 1006 (which probably already has one) all other points should disconnected....perform reset.... done....

    MPU: Were your jumpers just like mine? Meaning, did you ONLY have jumpers on positions 1 and 2...and all the rest were blank? If so, I will try it. If our jumpers are indeed the same, did you just simply remove 1 and 2, and then make a solder bridge on 7, 8, and 9 (and 6, which is missing on mine)? If so, I will try it. Thanks for your time.
