Yup, quite true. Not against older receivers, like my DX-302, but
bandSPREAD (yes, I incorrectly said bandPASS earlier, I spologize to those
of you that can't seem to get past that) is just stupid.


You have obviously never used a radio with a proper bandspread.

My Hallicrafters S-120 does it the wrong way - a separate Bandspread tuner
and knob that you use after tuning the main knob roughly where you want it.

My Grundig Satellit 2100 does it right. With the flip of a switch, it
breaks out the standard shortwave meter bands - 25, 31, 41 etc . - and
actually s p r e a d s them out, taking them from about 1 inch on the
tuning dial to almost 6 inches each. The calibration is spot on, and it
becomes easier than tuning in local FM stations. Where you had 5 stations
in a quarter turn of the tuning knob, you now have 1 station in a half turn.
Selectivity is incredible, and fading is largely eliminated - even without a
sync - because you can get exactly centered on the signal so easily.


That makes no sense unless you are also using a BFO in some mode like
side band.

I continue to be amazed by peoples lack of appreciation for sync
detection.
