  • dab radio craig brass schematics

    Hello , i have a dab ultimate radio module from craig brass hooked up to my carpc.
    Now is the device faulty,after inspecting it, i discovered a missing capacitor C7,it just dropped of the board.
    I tried to contact craig about the value of C7 but got no reply.
    Is anyone here that knows the value of this capacitor ,maybe by measuring ,so i can fix my board.

              remember to solder in right orientation as there is polarity on that
