So exactly how was that done?

Analog NTSC TV in the US was an AM video carrier with an FM audio 
carrier on VHF and UHF frequencies ranging from 55.25MHz (ch2) to 
885.25Mhz (ch 83).

Broadcast FM radio is similar... an FM audio carrier ranging between 
88 and 108MHz.

There are also VHF AM audio carriers on the aircraft band between 108 
and 135Mhz... these are low power automated traffic (and weather) 
information stations (ATIS), and there is one at just about every 
mid- to large-size airport.

Can you use any of those signals to detect ionized trails?
