That reminds me of a set-top b-b receiver I was testing long ago. While it met
all
the class B specs both rad and susc., when placed on top of a TV there were
interference issues because of the close proximity! (both from the TV and from
the
set-top!)

Hypothetical:
Should a receiver mounted on an antenna be lit up
during an emissions test? The receiver down-converts
the received signal??
Sure. It has oscillators whose emissions might cause interference. Even if
not required by law (Part 15 and receiver above 960 MHz not a radar
detector) it's
)

. The
amplitude of the IF signal would be proportional to received signal
strength, so if the IF were in the band controlled by your emissions limit,
that might be important.
