    Unhappy Analyzer AW07A bad QRG

    Hi,
    Abt 3 years I have the AW07A Analyzer.
    Worked ok first.
    Since certain time QRG are bad:
    160m - A = 11-21 MHz
    80m - B = 14-31
    40m - C = 27-49
    20/30m - D = 40-64
    10/15m - E = 57-66-47 (goes first up and then down)

    VHF/UHF seems to be ok.

    Are there any expirience with such ?
    (I can also not find any schematics in net - any available ?)

    Try it from another location, then you can be sure it's the equipment and not surrounding noise...

    Tnx already done
    in SV8 and TA3 - always same.

    Must be the VFO controlling - but without schematics no chance to find out.

    There are MFJ schematics out there, not for that exact model, but they could give you an idea of how its laid out.

    Apparently, the MFJ-266 is the same model, rebadged, which there are circuit diagrams for...

    Confused what is the QRG that is bad - are we talking about interference, as in QRM?

    No, QRM is QRM. QRG refers to frequency, as in "QRG?" meaning what is my frequency. This is why Q signals don't belong in a discussion that's happening with words.

    Knowing that QRG has to do with frequency, I'm not sure whether our Swiss friend's AW07 frequency is erratic or just rwong (that's REALLY wrong!); off by a few MHz.
