Kent,

You can't expect a high all-round performance from an affordable recorder.=

However, many low price digital recorders are very good, but only if you us=
e
them as intended.

What did you do with the unused input? Probably the interference you heard=

was digital "splash". Try shorting out the input of the unused channel with=

a short piece of wire.

> I can always remove the =E2=80=9Cempty=E2=80=9D channel with the unwanted=
 signal afterwards in Audacity, but would like not to have to do that.

Converting s stereo recording to mono requires a deliberate decision. The
cleanest way is to use the wanted channel only which is easiest in a sound=

editor, and which you will need anyway for editing out a wanted section and=

putting in fade-ins and fade-outs for presentation.

Without post editing, you would have to get the recording level exactly
right with unpredictable subjects which is impossible. Using an automatic
level function causes "pumping" of background sounds which sounds awful on =
a
wildlife recording. The desired method is to record low - which you can do=

with digital recording without loss of quality - and edit and adjust the
level later. One click with Audacity "Normalize".

>  Therefore I have tried engaging mono mix in order to blend the left and =
right signals down to mono. Nice function, but that does not removed the un=
wanted noise from the empty channel, but instead just adds the high pitched=
 signal it to the mono recording.

Even if you didn't have the digital noise in the second channel, you would=

still be adding input stage noise to your recording, theoretically at least=
