Only if the receiver section is of a type that is required to be
type-certified. In general, that's for VHF and above receivers.

Installing such a mod in a type-certified receiver voids the type
certification, which raises two separate issues.

(1) The receiver (or transceiver) can no longer be conveyed to
another party (sold, given, shipped, all the good words in Section
302(b) of the Comm Act) unless the manufacturer recertifies the
receiver with the mod (i.e. approved the mod and stated that with
the mod the receiver still meets seignal leakage specs).

(2) if the mod causes harmful interference to another licensed
station ("freebanders" are fair game but I never said that) then
you would be liable for using same.

Yeah, I know it's weird - put a preamp inside the VHF receiver and it
busts the type certification. Put it in a box with a transistor
battery and hook it to the receiver antenna terminal with a wire and
it doesn't. I never said that the equipment certification rules
were logical, only that they are "the rules".

Whatever worm is left in the can - put it on a hook and catch me a
trout.
