Re: [IRCA] 390A wrist



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.

73,
