    Problems after Mod. indepth



    OK here is the deal when I did the Master Reset as instructed it made the radio only allow me to select (A#### thru C####) (not D####) and if i try to load a Freq like 147.18 then (manually thru radio then it will not let me at all) (thru the computer software as soon it gets loaded to the Radio then the radio converts it to one of those others like Bo253 and I have not found any way to fix it. I have even tried to redo the jumper and reset again with no luck. Please help i am taking alot of heat for making the mod to begin with from my wife. ha ha Thanks Chad :headbang :oops:

    I was having some trouble with this mod. It ended up just being the reset.
    I needed to push power, dw/rev, an/low, mw/dmr all at the time time.
    the instructions at the beginning of this thread said to just push power, an/low, mw/dmr.

    Hope this helps somebody else.

    I did not have any problems at all with auto repeater shift after removing the solder and resetting. It functions as it did before the mod. Hope this helps those with questions.

    FT-2900 mod

    Followed picture. on my board it was upside down on soldier spot. removed the spot and reset as instructed. repeater mode was fine. didn't have to reset. I would recommend backing up radio first. once you reset. you will have to open a blank area on programming software and let it read radio after reset. then redownload freq. works great and tx opened now to all of 2m.

    Do you use proper power supply for your 2900? If you use weak power supply, and try to use your 2900 on HI power, your 2900 will restart after pressing PTT button. Remember, your 2900 need minimum 15A on HI power !

    I just did this mod on a 2015 model and it works great. Interesting to note that there was a small black chip on the spot. I heated it with the soldering iron and it came right off.

    Just got this radio and the mod was very easy with the photos and information provided. The problem I have now is that I can't clone/program the radio after the mod. I was able to download radio image with CHIRP (today's daily snapshot) before the mod, but can't do it after. I even clipped and recrimped the USB cable to rule out a cable problem. I can program the radio manually, but it would be nice to use CHIRP, despite the (currently) partial support for the FT-2900. If anyone has any experience or suggestions on this, I'd appreciate this. If this is a result of the mod, it would be good to take this into account before doing it.
