    IIRC "FAIL001" indicates a VCO unlock, in other words the radio is attempting to tune a frequency outside the range of the VCO(s), this usually comes about when the band limits in CPS have been opened up beyond what the radio is physically capable of?

    What band split is your radio (or just provide the model number)? Does the error only occur on certain frequencies and what are they?

    I think there are other factors which can also influence VCO lock such as ambient temperature but this is unlikely if operating within specs?
