Thread: Bad 2.3 transmitter

  1. #11
    Dick,

    I put your tx on the frequency counter and its transmitting on 2.1 GHz. I removed the board and could not find anything visually wrong with it. My guess is the quartz crystal got damaged in the impact? I sent you a PM on replacing it.

    It IS overheating. You absolutely cannot run those without the case! I have tried several times and done many experiments. Even right in the prop wash they get quite warm.

    If it is broken, fix it. if it isn't broken, I'll soon fix that.

    Can any of them be run bare and be ok or do they all need at least a heatsink? Thinking of trying something besides the Lawmates until IRC quits teasing us and gets a new 2.4 lineup out.
    Most of the money I made this year I spent on FPV,the rest I just wasted.

    I agree with Alex, you do need a heatsink. The main power transistor is on the backside in the middle. I mount my TX face down (LED down) and stick a heatsink on the middle of back. So far I have not had any issues. A heatsink on the front will probably not be sufficient.

    This is the one I use, it has the sticky back.

    I run a heatsink on mine with OCZ Freeze thermal paste. the TX is also coated in copper tape for equal heat distribution.
