    Hi guys Happy new year

    I've been working on a radio test set

    The unit passes all of it's self test except the Spectrum analyzer test

    When checking the transmitter on it's own every thing seems fine but when checking the receiver there seems to be no signal detected on the receiver and spectrum analyzer.

    I've changed 2 boards associated with the spectrum analyzer(board AE6 and AE6/2),but it still produces the same problems stated above.

    If anyone can help with this problem i would appreciate it.
