Topband: Orion receiver optimization doc

[Wes Attaway (N5WA)]

I did not get this impression at all.  There are several possible
settings described for weak signal reception.  I assume the
operator would make appropriate decisions based on the conditions
that exist at the time.

It seems like the Orion has enough possible settings to cover any
condition ..... this is both a blessing and a curse.  To get the
most out of it the operator will actually have to understand the
controls and make some decisions.

Just read the "optimal uses of orion..." info and, for weak
signal reception
this is what I understand:

Dont use the NR---can not tell weak sig from noise, and takes the
weak sig
out.

Dont use the AGC---as it hangs on the most recent noise peaks,
covering the
weak sig.

Dont use the narrow roofing filter setting---like all narrow
filters, it
adds attenuation, killing the weak sig.

Apparently the Orion was designed for contesting, which is fine.
But when
do the weak sig topbanders get a break in this scenario?
