lesson on logic as pertaining to the E1
 
remember logic from school ?????


if all quality communications receivers don't have a built in ferrite MW
antenna
AND
the E1 is used almost exclusively as a base station like most communications
receivers
THEN
it doesn't matter if the E1 has no ferrite MW antenna built in


make sense class ???????????

I never went to any kind of radio school,so I dont know.How about this
"logic"? World turning back on American brands.Article is at
www.worldnetdaily.com If that radio was an American brand name
radio,would it sell elsewhere around the World?

No, it doesn't make sense. If the radio is in portable form, I believe it
should have an internal ferrite antenna. My guess is that the designers
didn't want to go through the effort to provide the required shielding in
order to make this possible.
I have built several MW receivers and I know that you really need to shield
and decouple the control circuitry in order to not have harmonics of the
clock, broadband noise, etc from being picked up by the loopstick antenna.
You need to have worst case radiation of less than .2uV to make the receiver
usable. I've been there, done that.

in that case, I would rather have no antenna than a bad one !


thanks for the lesson !

I understand why you feel that way Mike, but it is still possible to have a
good internal antenna. I think that the goal was to make this radio as
cheaply as possible (not a bad thing in itself). I will end up picking up
one of them as a fun to play with "toy". Right now, the Grundig 3400 is my
current "toy", but moods change from time to time.
I am waiting for them to come out with an active antenna for this model.
Part of the plan with some of these radios seems to be the money that can be
made on the "add-ons". Still, it would be interesting to see the schematic
(ha! that will be the day!)

We need to keep in mind that Drake had a part in designing the E1 as
with the Satellit 800. Remember, the Satellit 800 is basically a Drake
SW8 with a larger speaker and an ADDED FERRIT ANTENNA. The Drake SW8
had NO ferrit antenna but rather used the internal whip antenna for MW
reception.

In my particular case, the two distant MW stations I listen two during
daytime hours come in without any co-channel interference on my car
radio, which uses a whip antenna.

Of course a ferrit antenna would be nice for direction and interference
nulling, but in my case I always have to turn the radio to an odd
position for reception of the stations I listen to. For me, the whip
will actually be better, and I will use an external loop for other
dxing.

Yes, I do. They were interesting courses taught by bearded professors
who were probably beatniks in an earlier life.



if all quality communications receivers don't have a built in ferrite MW
antenna


There are (actually were) several companies that made quality receivers
capable of AM, FM and shortwave broadcast reception. And there are
some truly trashy receivers capable of shortwave only reception.


AND
the E1 is used almost exclusively as a base station like most communications
receivers


I'm not sure what the definition of base station receiver really is,
but I'm assuming it is one that can be powered by AC and set on a
table. Many of us also listen to SW as well as AM and FM on receivers
that sit on desks.


THEN
it doesn't matter if the E1 has no ferrite MW antenna built in


This doesn't follow. If you want to play logic then drag out your venn
diagrams and start mapping the various kinds of receivers and find the
overlaps. You hopefully will find that not all quality shortwave
receivers are limited to only hf reception. You will also find that
there is a small subset with coverage limited to the HF spectrum.

Yes, this is what everyone keeps saying, much to the delight of Eton's
marketing department, I'm sure. However, no one has yet been able to
spell out exactly what Drake's role was. Nor can anyone explain why
Drake, which sold the 800, is not selling the E1, or why Drake, which
serviced the 800, is not servicing the E1.

There are knockoff copies of American brand name vehicles being made in
China right now. www.chinesecars.net They sell for much less in
price than the American brand name vehicles being manufactured here in
U.S.A.What has that got to do with radio? Well,take a look at the
electronic things that have American brand names on them that are being
made in China and other foreign countries.Governor haley barbour (I can
not spell any! politicians name with capital letters,it is practically
physically and mentally impossible for me to do so) of my home state of
Mississippi recently got back to Jackson from a trip to China.Of course
most of us know Nissan (Nissan used to be called Datsun,Datsun means
Bluebird) is not an American brand name although there is a Nissan plant
just north of Jackson about fifteen miles or less and that Nissan
plant/factory has developed a line of cars (Aprexa,or something like
that,I think is the name of the cars) that have the suspension system
and some other things designed/developed for the Chinese market.That
Nissan plant/factory near Jackson is going to be selling cars to
China,someday,probally,China will be manufacturing the same line or
similar of cars in China and selling them to Americans.I have said it
here in this news group,someday Chinese manufactured
cars,trucks,vans,suvs,boat engines,motorcycles,ect will be showing up in
American dealers showrooms and someday,there will not be anymore
factories in America manufacturing those products.Take a look at what
has happened to American name brand radios that used to be manufactured
in America,RCA,Sylvania,Emerson,Magnavox,Motorola and others.And tv sets
and on and on and on,,,,,,,,,, We are digging a hole we will never get
out of,thanks to fed govt and free trade and nafta and gatt and hold on
to your hats folks,there is a new one the Crooked B......s in fed govt
just recently approved and signed on to to help Sell U.S.A.Down The
River even some more,cafta.(guess who is getting rich and richer from
that and guess who gets poorer and poorer?)There are other countries in
Asia that are becoming the "New China",India is one of them,so is
Malaysia and other third world countries.Sure,I know the E1 radios are
not an American name brand,but y'all get me driff.I remember when
America used to be self sufficient and most of what Americans bought in
American stores was Manufactured in America,except for Chrome which we
get from Africa and Russia,without Chrome (I am not talking about the
Chrome plating on auto bumpers and similar thingys either) we would be
in big trouble Militarily speaking. cuhulin

My understanding is that Drake sold the design of the SW8 (and maybe
the R8B??) to Eton.

Drake no longer sells the Satellit 800 or any other SW receiver. Drake
decided it was best to sell the plans to their receivers rather than
continue manufacturing them as current prices would be too high for any
kind of market with the competition from imported receivers. Notice
all the complaints in this newgroup about the $499 price of the Eton
E1, yet the Satellit 500 and the Satellit 700 both sold for $500. The
Drake SW8 was just under $800 and nobody complained about the price.
Of course Drake quality is higher than Eton's, but most of us like
getting a new radio every few years, and very few care about getting a
receiver that will last 20 years or so. I paid $900 for my Satellit
650. Great quality receiver. But my $500 Satellit 800 has better SW
reception and many more features. Not the great sound quality of the
650, but a fantastic selectable sideband sync detector as well as
fast/slow AGC.

If the E1 is a great receiver, then it is well worth the $499 price
tag. Pay less, get less.
