[Amps] Pi-L Network

[Peter Voelpel]

On my 160m amp the improvement is 12db,
beside the much better bandwith on that wide band without need for retuning.

Thinking of it as a low pass filter, going from three elements to four I'd
expect more than 6dB harmonic improvement for the same operating bandwidth.
