    Recently purchased a radio from a not going to be mentioned ham for $700.
    Works fine for a few days and then one day I go to transmit AND..........

    Nothing.... no receive either. Seems to be caused by the moveent of the VFO knob or RIT. or switching bands,modes but mostly VFO.

    So I found out, Power cycle of the radio fixes the immediate issue of loss of tx/rd.

    But there is another clue. Cycling the mode selector though the modes when it makes the switch to CW the vfo adds 000.000.600 is 28.400.000 would now have 28.400.600

    Any messing with the vfo can cause the fault including RIT/XIT adjustments.


    Even after the fault which happens on HF section and cannot be remedied without power off. The vhf/uhf stills works even after her the fault.

    Thanks for any replies guidance.

    I can't find a quick answer the fits your specific description.

    Peter, at TRX Bench on YouTube has several videos on IC-7000 repairs which are enlightening and easy to watch. Ribbon cables seem to be a frequent cause of intermittent problems. Good luck!

    Peter at TRX BENCH states he does not answer requests for support.

    Do you know of a way to contact him directly for sending a radio to him?

    First question: Have you done a full reset? Per the manual...
    Before first applying power, make sure all connec- tions required for your system are complete by refer- ring to Chapter 2. Then, reset the transceiver using the following procedure.

    Resetting CLEARS all programmed contents in memory channels and returns default values in set mode.

    Make sure the transceiver power is OFF.
    While pushing and holding (UP BAND) and

    (DOWN BAND), push [PWR] to start resetting.
    • The internal CPU is reset.
    • The display changes to ‘ALL CLEAR,’ ‘RF power 100%’

    No. Peter is in France. If you need outside repairs I recommend sending to Icom in Washington.

    Hi Brian - KE0NJG,

    I red your text about the IC700 problem of stop transmiting and receiveing after change de frequency, etc. Have you fixed this problem? If yes , what was the solution?

    I have the same failure in my IC7000.
