    Adding a "Q" multiplier such as a Heath QF-1 or HD-11 definitely helps with a number of the receivers without a crystal filter and even with some receivers that do have a crystal filter.

    My preferred AM receiver.
    I have 4 of the Military R274 versions.
    I also like the SX-28.

    I use a SX73 which shows some wear that Ive completely gone thru and a never installed 274 (no letter) is a shelf queen. IMO they are better by far than the SP-600 versions. The healthy emission reserve of the 6Y6 plus substantial output transformer contribute to easy listening.

    While that often requires adding some hole(s) in the RX back panel that is exactly what I did to a HQ-129X in mid 1956 while still a Novice, and then added a BC-453 as a Q 5er. The CW selectivity became fantastic. Back then adding holes was a no brainer as nobody considered any future interest in a radio that was already outdated. My current HQ-129X has the same setup along with the Viking 1 and Model 122 VFO to duplicate the package.
