[Premium-Rx] Best Premium Receiver?

I'm with Don.  As a stand alone rx, the  9500 is better insofaras Synch 
Detection, though the HF-1000's SAM ain't too  bad.  But coupled with the SE-3, the 
WJ wins (if the 7800 is indeed an  accurate representation of the 9500).  A 
true comparison would be between  the WJ w/SE-3 and the 9500 w/SE-3.  

But's it's truly an "apples and  oranges" comparison, as the 9500 covers so 
much more than HF, plus the Dynamic  Range is superior because of the many 
choices of roofing filters.  Even so,  I'd rather have 2-3 WJs for the price of 
ONE 9500.  I use several receivers  through a Harris multicoupler, listening for 
a station's simultaneous broadcasts  for accurate verification.  I use ONE 
SE-3 through a 12 position  SE-6.  

I have one of Chuck's modified R390As and this is truly hard  to beat on 
audio recovery, hearing .07 microvolt signals, with minimal noise  floor.

My station's at www.qrz.com/ni6s

Haven't had this much fun  on the Prem Rx List for a while!  Glad to see it 
become lively again, just  like in 1999!!

Ed NI6S

I don't think I ever said  anything about the WJ standalone - I have ALWAYS
used the SE3 in combination  for the results I have reported on.

It’s the combination of the  two.  

Its similar to saying "it’s the antenna not the receiver that  matters" -
again its both not just one or the other.

By the way, the  combination of the R-390A and the SE-3 is pretty sweet too.
Chuck Rippel  turned me on to this one when we talked at a Grayland
DXpedition (not ham  dxpedition, but SWL/TPDX).

You probably back in premium receiver where  this R-390A/SE3 combination
picked up the last of the Radio St Helena  broadcasts (off the old commercial
equipment) fading in several minutes  before even the WJ/SE-3 did, then
followed by R3030A/SE3, the R590A(I recall  having an SE-3 on this one as
well but I'd have to check) as well by  535D(Kiwa modified) and then finally
the 545?  That makes the  R-390A/SE-3 even more sensitive to weak signals by
a few minutes during their  fade-in here on the left coast.

I certainly enjoy my WJ's for weak signal  dxing. If I want dx music, the
Kiwa-modified NRD535D is even better than the  others.

It proves that the SE3 and not the WJ makes the  difference,doesn't it?

Clemens

The article does not say that it was done  with a SE-3 with the WJ.

Even you know that the synch detector of the  WJ's isn't good without the
SE-3.

So this does not prove anything  about the WJ+SE-3, does it?

Perhaps you can point to such a  test?

Hi,

>For example, I read that the  WJ
>HF-1000A/8711A blows away the Icom 7800's  receiver or that the  Icom
IC-R9500
>isn't necessarily the greatest.

It would be  interesting to know where you've read such a biased nonsense.
Go  to
http://www.ratzer.at/9500.php

Then scroll down just below the third  picture.
Load down the the mp3 file on the end of the second text  paragraph,see
below:

"Mittelwellenempfang: Radio Tien Gold,  Niederlande auf 1008 kHz. Sehr gut
erkennbar die
ausgezeichnete  Arbeitsweise des Synch-AM Empfangs im 9500, welcher das
Fading des  Musiksenders
wesentlich besser verarbeiten kann als der HF1000A. Aufnahme von  Radio Tien
Gold, Niederlande,
8. März 2007, 2250 UT. Bandbreite 8 kHz.  Reihenfolge: 30 sec 9500, 30 sec
HF1000A, 30 sec
9500, 30 sec HF1000A. mp3  Audiodatei, 1,8 MB"

Now you can hear a *proof* not a rumor which one  performs better.
Both rx operate in synch am and the 9500 copes much better  with the fading
am signal than the
HF1000A.
The sequence is 30 seconds  9500,30seconds HF1000A,30seconds 9500,30seconds
HF1000A.

Regarding DR3  and other essential specs the 9500's rx on sw is virtually
identical to  the
7800's  rx.

Just curious  as to how some premium  receivers stack up against some others,
either  consumer or commercial-grade  rigs. For example, I read that the  WJ
HF-1000A/8711A blows away the Icom 7800's  receiver or that the  Icom
IC-R9500
isn't necessarily the greatest.

My  personal  favorite is indeed the HF-1000A because of it's sensitivity,
selectivity and  superb audio recovery.  A close second is the Harris
RF-590A....Just  wondering what some of your favorites may be....I challenge
my
receivers  through their ability to pull out weak signals on the  Tropical
Bands....The
HF-1000 seems to hear sigs my other receivers  cannot.  Your  mileage may
vary.  Please share your  experiences....

Regards,
Ed   NI6S
