The radio is tuned only to receive a specific frequency.
That pulse is composed of many frequencies. Frequency that
interferes with radio reception is a unique sine wave
frequency
within that pulse. Just one of so many frequencies that
create the pulse. Pulses - like all waveforms - are a
summation of basic sine waves at different frequencies,
amplitudes, and phases. The radio does not receive a pulse.
It receives only parts of a waveform that are specific to its
tuned frequency. Fourier analysis demonstrates the concept.
The radio does not receive a pulse so much as it receives one
frequency that was part of that pulse.

A chart for the frequency spectrum of lightning is available

BTW, here's another page in that same series:

I guess you would have to claim there's positive AC and negative AC to
be consistent with it.
