G'day,

Robert, AX2TAR, tried his switch mode LF transmitter without a low pass
filter.   His 3rd harmonic was just visible on Argo, but his 19th harmonic
at about 3.3MHz was S9 here about 10km away.

The 19th harmonic was probably where his wire was a halfwave long and
excited via the stray capacitance across his loading coil.
