I don't suppose that is a nice way to avoid the sound
issues with the IC-R71A??

Much of the distortion with R71, which can approach 20%, are
related to the four mixers. Sometimes a good sound system at the

REC
out can make an improvement, depending on speaker selection, but
often, what a higher definition audio system does, is merely

enhance
the audibility of the distortion that's otherwise masked by the
'smearing' of the waveform created by the use of ceramic

capacitors
in the audio path. KIWA offers a nice mod for the audio of R71.

And
it's reasonably priced. And it DOES clean up the audio path. But

the
cleaner audio path only served, in the three units I've heard that
were so modified, to call attention to distortions that were
generated in pre-audio stages. There, currently are no mods to
attenuate those distortions.



How bad is the sound on the R71A, really?? I've had
an R70 in the past, and I didn't think it was that bad
there, but fidelity wise a Drake or the Sat 800 is better.
If it's in the realm of the R70 as far as how bad the sound
is, it's livable.




I know people who listened to R71 for MWBC all day every day. I
was one of them, and I wasn't alone.

Unless you're focussing on the audio, it's very likely you'll
never notice it.

Example, I never really paid attention to the clipping on WLS
until I migrated from R71, to Sat 650. The cleaner audio path made
the clipping distortion (over processing at the transmitter)
noticeable, and on the higher fidelity audio path, irritating.
Compared to WGN, it was a night and day difference. When I migrated
to Fanfare FTA-100, the difference was greater still.

With R71, WGN or WLS...it was AM radio. And there were few
apparent differences between the audio of the two.

If you didn't have a problem with R70, you won't have a problem
with R71.


Hmm. I guess then I can live with it. Maybe next
year (or the year after) I'll try to obtain one of them
(or the R-5000) via eBay. Methinks that the R8B
will have to wait a while until the used prices return
to normal.
