    The start up waveform may give some indication where the problem is, see FAQ section --TX Trouble Shooting Guide slide 6. Do you see any indication of communications and RX trying to tune TX.
    Some things to check:
    1.) EN 1 and 2 are LOW or open (internal pull down)---JP1 and JP2
    2.) No voltage applied to Adapter input --- J1
    3.) TS--JP3 in the DIS position
    4.) ILIM jumper in place -- JP6 in fixed position
