Fred,
Actually, your premise is incorrect. With a 250Hz wide filter centered =
on 750Hz tone, installed in the N1 or N2 position, and with a low offset =
frequency such as 400HZ, you'll find great attenuation introduced due to =
the received signal passing through the slope of the filter skirt.=20
Try it. Tune in a 400Hz received tone that way.
73, Roy =
I 'm hoping =
that you might be able to explain the need for the lower offset
cw filters. the omni 6 has an adjustable sidetone offset control, and =
also
an adjustable passband tuning that can recenter the 6.3 and 9.0 mhz =
filters
to be at the new offset. so, why buy a 500 hz offset cw filter instead =
of
the 750hz offset filters?
