Same here.

As a rule arcs, as created in a poorly installed fence, are 
very wide bandwidth with very gradual level changes as 
receiver frequency is varied.

Tics that are band specific or periodic in frequencies they 
affect are from sources like clocked signals in 
microprocessor control systems.
