Most radios arguably have one additional stage of "conversion" that the
specs and ads *usually* omit - unless the ad writer is seeking to state
something that while true is usually not presented as a spec or a
defining characteristic.
That is the final conversion to baseband audio. A radio with two
distinct IF frequencies would have two LO injection frequencies *plus* a
final injection at the last IF frequency to get down to baseband audio.
A total of three "conversions."
I have no comment on the legitimacy of such marketing and advertising,
but technically a doube-IF radio does in fact employ three frequency
conversions. Thus is can technically be called a "triple-conversion
radio."
