Lots and lots of these rigs are going into dipoles with no tuner.
That will radiate just fine on the third harmonic, and the pattern
may well be such that your FCC monitor is sitting in a third harmonic lobe.
In the general case, can't count on the antenna system to to make the uBitx legal.
The uBitx really should be clean out of the box.

Small point...the FCC monitors would be testing received RF.? This may be via a remote monitoring
station or from a van parked down the street from your house.? This means that the full system,
including ATU and antenna will be present in signal analysis.? Most discussions fail to include
filtering effects of these components that are external to your transceiver (some designs are better
than others).? This lends credibility to having another ham who is some distance from your location
perform tests to see how pure your signal might be. ?

Testing in an anechoic chamber is the way equipment is tested for type approval or in case of
legal proceedings.?
