I have not seen this list in years, but it seems to me
that just about any receiver with an RF preselection
stage would satisfy this requirement. BTW, as i have
posted previously, apparently other Navies were not
concerned with this issue.
I agree that it has to deal more with shipboard
compatibility, rather than DF'ing, altho possibly
this semi-official  myth arose because of Americans' bewilderment and panic
at the horrendous ship losses when the USA entered the war. And also that of
all the
combatants, only the US had the means to to produce such overbuilt
receivers. I say semi-official because
i personally have not seen any USN lit that talks about
ships being df'd by their receivers, altho Scott ads,
as seen in National Geographic and other mags,
certainly tout this feature, so-called.
By the way, i have a German UHF search receiver,
called "Samos", which uses no RF stage, and which
the US Gov't directory of German equipment describes
as "heavily radiating". (!)
