You got it. If you're tuning to 750 in AM mode with your 2.4 kHz filter, your filter limits you to receiving 1.2 kHz of audio.
If you'll re-tune the radio to 751.2 kHz in AM mode, you'll get 2.4 kHz of audio from the upper sideband of the signal.

Is what your saying is, if I don't outset the passband in the AM mode, in reality I have about 1.2 khz on each side? If that is the case, no wonder it is tight. In the case of the SPR4 there in no passband tuning and tuning off the channel a bit, I either lose the signal or the splatter covers it up. I wish the SPR4 had crystal phasing. It would be nice. The notch filter helps, but it isn't the same as it was on the SP-600. The SPR4 has about 4.0 khz in the wide mode. I think is says 4.8, but being a Drake it is tighter than the specs in most cases. 73, Patrick Patrick Martin KAVT Reception Manager _______________________________________________ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com _______________________________________________ IRCA mailing list IRCA@hard-core-dx.com http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: irca@hard-core-dx.com
