Mark, 1.2 kHz down would be an image response of your xmt signal if the sidetone frequency is the default value of 600 Hz -- as if the opposite sideband was not being suppressed. You did not say what type of radio. IF FLEX-1500, FLEX-3000, or FLEX-5000, try doing a reset to factory

Mark, I no longer have your original message, but if the "spur" was 1.2 kHz as I recall, I'm wondering if you have a local AM broadcast station which may have mixed in your final. I have seen sum and difference products from local transmitters mixing in a transmitter result in "spurs".

Mark, Harmonics are integral multiples of your frequency so whatever was happening it wasn't a harmonic of your signal. How close was the reporting station to your QTH? Strange things happen when someone experiences fundamental overload of their receiver. If able, arrange to have a look at
