French claim that the superhet was first designed by Lucien Levy of
VCO for VHF applications, an operating range of 100MHz to 1GHz, precision baseband filtering with selectable bandwidths and the smallest PCB area, typically less than 50 per cent of a dual superhet.

An 80m hand-held DF receiver isn't difficult to build, especially using direct conversion (though a superhet isn't that much more difficult and gives much better performance.)
