This morning I went through the freq display adjustment and evaluation with much more care than the first time, when I originally discovered the trimmer control.

Perhaps initially I didn't leave the radio on long enough for the circuitry to warm up completely, because now I find ZERO imbalance between LSB and USB across HF and medium wave. Probably someone with test equipment could find something wrong, but to my ears the sound is identical between sidebands when the filter bandwidth is the same, the radio is tuned to the carrier, and the PBT is centered.

As far as frequency display accuracy, I now have the display spot-on throughout the HF range, and only 20 Hz error near the bottom of medium wave. That is, zero beat on my local on 570 kHz needs to be set to 570.02 kHz for natural speech in LSB and USB (which still sounds "balanced between LSB and USB at 570.02). For my local on 1000 kHz, I need to tune to 1000.01 kHz for zero beat, and on 1560 kHz the zero beat point is right at 1560.

The radio is quite stable enough for pleasant and useful ECSS tuning of DX after the warm-up, which is quite an accomplishment for a portable receiver!

I now want to investigate how long it actually takes for the drift to settle down, as I left the radio on over night before doing my more careful adjustment and test.

BTW, just to clarify my earlier message, the frequency adjustment hole is found in the copper cover that's beneath the left slot OF THE RIGHT GROUP of ventilation holes on the back. It is *not* under the very far left vent slot.

That is pretty close to amazing performance for a portable. Thanks for
posting some very useful information.

I have to take back some of the evil thoughts I had about the intelligence
level of Eton radio designers and engineers after reading your posts.
They weren't too stupid to realize the bad designs of their radios and had
the fore thought to incorporate the alignment hole through the case.

For them, that's what I call: Forward thinking!

NOTE: Watch out - the batteries blow up, when used with the AC adaptor
!

So, what is the point of plopping down $500 for this radio - there is
not much of interest on shortwave anymore, one can buy a $25 digital
PLL AM/FM radio for AM DXing (THE E1 DOESN'T EVEN HAVE AN INTERNAL
FERRITE-BAR ANTENNA, OR COME WITH A SATELLITE ANTENNA !), and one can
buy a satellite radio for $50, now. Also, after getting $500
in-the-hole, one gets to shell out a monthly fee for satellite radio,
plus an activation fee - a bigger ripoff than cable T.V. !
Evidentually, there are major technical problems with the actual
satellites, so its future is in question !

So, what is the bottom-line ? Well let's see, $500 for the radio,
probably another $100 - $200 for the AM and satellite external
antennas, $9 - $12 monthly fee, and the activation fee. Is this another
blunder by Grundig/Eton/Tecsun, or a total ripoff - I suspect a bit of
both !

This baby, I believe, is assembled in India, while the rest of the
Grundig/Eton/Tecsun junk is made in China. I wonder, if the E1 is as
cheap as, the Grundig S350 ?

Andes" are now gone from SW, too):

David,

I am shocked your would recommend this new radio from Eton.
Honest?, DO YOU KNOW WHAT IS WRONG WITH IT? It does not have Digital
Radio Mondale! Who in 2005/2006 would spend $500.00 for a top of the
line portable without it? In few years the shortwave part of this radio
will be useless. DW is leaving analog shortwave by June 2006. Radio New
Zealand by the end of December 2006.

I would hope you would admit your mistake and if not withdrawing your
recommendation at least make note of the lack of Digital Radio Mondale
and why that is important!

I'm curious as to what other portable radios currently on the market you'd
consider to be better at basic DXing parameters such as:

-stability and tuning step suitable for ECSS tuning
-IF shift for QRM avoidance
-good sensitivity with decent IP3
-weak signal S-AM locking with selectable sideband
-three or more useful bandwidths

The AR7030 doesn't count... it's not a true portable with batteries and
integral antenna. The Palstar R30 has batteries but no antenna; it's a shame
it lacks S-AM and IF shift.

What DX catches can you list, that you've heard with the better portable you
have in mind?

I rarely respond to trollers...but *maybe* an interesting discussion will
come of this.

Also, if you're interested in a real discussion of radios, what's your real
name, Mr. Radio Buff?

I used to live near the Wabash River in Terre Haute, IN. I never
figured out why people made such a big deal of it. There never was any
moonlight on the Wabash either because it ran in the wrong direction to
reflect much moonlight, and I never saw any candlelight to make me long
for my Indiana home. People had electricity. I did catch some catfish
though and then I wound up in the Pearl River swamp later on. After
that, I got caught by hurricane Katrina and my wife moved back to
Indiana because she hates hurricanes and me. Especially me.

Somehow, it all got started with the Wabash. I hate the Wabash.

The train probably sucks too.
