Re: [TenTec] Orion AGC setting for QRN

Just a biger spark!

Lightning energy spectra goes to 100 kHz which implies basic 10 usec pulse
slightly streched by 15 kHz first IF filter.
Repetitive nature interference is more annoying for human brain.  Duty cycle
of fence sparks is very low.

USA OTHR had better spectrum spreading and caused less QRM.
Plenty of lower power OTHR QRM even these days as this is "poor man" long
distance radar.
