Rick, The mod on the SPR4 enabled the 2.3 crystal filter to work on AM. It is one tight filter too.But too tight to understand some weaker audio. The SP-600 had the 2.3 Crystal filter too, but it was not quite as narrow. The 2.3 L/C 50 khz IF filters in the R8 are too tight too, so I tune in ECSS mostly there.
