I cannot answer this question authoritatively. I can say that a VOR receiver procured after 1970 by US DoD would have had MIL-STD-461 CS103, CS104, CS105 and possibly CS108 levied as part of the procurement, and these requirements drive receiver front end design. The commercial aircraft equivalent for EMC, RTCA/DO-160, has no such requirements, but that does not exclude either a different RTCA standard, or some other procurement specification covering receiver front end design in the commercial world.
