Re: Eton E100 tuning via knob

Gary Kinsman
 

Hi Gary,

After pulling the back off of my E100 using John's instructions, I
immediately saw the problem: the "disk" on the tuning shaft was
rubbing on the inside of the case, so much so that it caused the
section of the case through which the tuning shaft goes to move in
and out slightly on every rotation of the knob.

I figured I could solve the problem by putting a shim between the
inside edge of the case and the inner frame of the radio. I found an
O-ring with the proper thickness and diameter, cut a small section
out of it, then placed it appropriately. This stopped the binding of
the tuning knob on part of its rotation. It rotates fairly easily
over its whole rotation now, with minimal friction.

The tuning encoder is still kind of finicky. On some parts of the
rotation it's very easy to get accurate 1 kHz increments. On other
parts of the rotation it requires some care to avoid getting 0 kHz
or 2 kHz increments instead. I think my E10 does the same thing, so
this is probably common with these cheap encoders. Since I only use
the tuning knob for fine tuning -- it's too slow for anything else --
I may put a white mark on the knob, centered on the best part of
the rotation, for easy reference.

It's funny that you mentioned the antenna wire breaking off -- mine
did exactly that. It looks like it may have just been hanging by a
thread. Since the contact is fixed the the back of the plastic case,
I didn't want to solder it, because it might melt the case. I simply
stripped the end of the wire, then placed it between the threaded,
square antenna mounting end and the contact that is fixed to the
back of the case, then carefully tightened the screw that holds the
antenna to the case. Not elegant, but it seems to work just fine.

Having 1 kHz tuning steps is a big advantage of the E100 over the
other ultralights, but I notice that my E100 is far more prone to
hets than my DT-200VX, sometimes even on strong, local stations.
Usually tuning 1 or 2 kHz up or down can get rid of the hets on the
E100, but not always. The DT-200VX rarely has hets when tuned to the
same frequency as the E100. I suspect that the stock IF filter in
the E100 is somewhat wider than the one in the DT-200VX.

Regards,
Gary

Gary,

In general, the "old" E100's have a pretty good quality
control record, but I have seen a defective stock loopstick, and
a couple of new units with whip antenna wires broken off.
Eventually the E100 owners will have a detailed record of
potential problems, and how to solve them. If you can solve
your tuning shaft problem by disassembly or lubrication, please
let us know about your procedure. Otherwise, an owner with an
inoperative E100 might have a part you need, or you could track
down a parts unit on eBay, usually very
cheaply.

Hello Guys,

The new Ultralight Radio AM-DX Summertime Shootout file has
been
uploaded to dxer.ca, including full information and photos on the
SRF-S84, SRF-M97,
E100, SRF-M37W, and DT-400W models. Extremely detailed
information is
provided for sensitivity, selectivity, nulling ability,
images/spurs, AGC, audio
quality, digital tuning noise, and quality control record. In
addition, a
bonus section is provided comparing all these models with all the
other
top-rated Ultralight radio models (SRF-59, SRF-39FP, SRF-T615, DT-
210V and DT-200VX
units).

If you have any question at all about the top Ultralight
radio models,
the answer is probably available in this Shootout. Get ready for
a SUPER
fall DX season!

Ron,

Thanks for the link. I just ordered a second one for
myself. With the free shipping, it costs the same as
my first one that I purchased from Amazon that I had
to pay shipping for!

Gary D's confidence in these radios ...


After ordering three DT-400W review models for the
Summertime Shootout and having all three units arrive
from the factory in an excellent state of wide-band
AM sensitivity, I can strongly recommend this
innovative new receiver for any Ultralight DXer looking
for a thrilling fall DX season. It is highly unusual
for the Chinese factories to consistently perform
excellent AM alignments, but Sangean has apparently
managed to accomplish this. As long as you can
tolerate the yellow color, you'll love it :>)
makes me feel pretty good that this second one should
perform as good as my first one.

Plus, I personally think the yellow color is attractive!
The "yellow jersey" color is a conversation starter!
Good way to get others into the hobby!!

Gary, what a great job you have done putting together the 2008 summer
shootout. i haven't read everything yet but am very impressed with
your work. so much so i ordered a DT400W today. See previous post for
link from where i purchased it.

i did see one typo in the sensitivity table, in the SRF-T615 row, 3rd
column it reads "steady weak audio (30". my guess is should read
'steady weak audio (3)'. i'm not trying to lint pick but did notice it
and thought you may want to correct the file for future use.

Thank you very much for all your enjoyable hard work. i am sure
everyone will make good use of this info

Wow! That's a cool-looking radio!

However, the strict definitions set up by the Ultralight
Definitions Committee prohibit any radio with a built-in
MP3 player to be classified as an Ultralight.

Taken from the Definitions Document:

http://tinyurl.com/6mvrl3

"In keeping with the concept of limiting ourselves
to shirt pocket portables, the Committee has determined
that Novelty Radios (Coca Cola radio, Mr. M&M radio,

radio+flashlight, radio+Swiss Army Knife, etc.)"

Hello Joe and Ron,
 
     Thank you both for the excellent links and information on the new Sangean DT-400W model.

     As explained in the Shootout, the E100 would still be the preferable choice for modifications and/or 9 kHz split frequency DXers, but with two outstanding Ultralight models to choose from, this upcoming fall DX season should be a real thriller for everybody!

Hello Guys,
 
     The new Sangean DT-400W was the big surprise of the 5 models tested in the Summertime Shootout, and does indeed have wide-band sensitivity superior to all other Ultralight models (including the SRF-T615 and the E100).  In order to confirm that this was not a fluke, three DT-400W models were ordered, and all three had the same great AM performance.  Accordingly, Ultralight enthusiasts can have confidence in ordering this model, for highly sensitive Ultralight DXing this fall season.
 
     Full details on the DT-400W evaluation, including its relative performance against the E100 and SRF-T615 models (as well as all other top Ultralight models) will be contained in the Summertime Shootout review, which is in the final stages of completion and should be available very shortly to all enthusiasts.

Re: Eton E100 tuning via knob

Gary Kinsman
 

Hi Gary,

Thanks for replying to my question. My E100 is S/N E10-0704030006,
purchased from Durham Radio back in May.

It does appear that the white tuning shaft to which the tuning knob
attaches does "wobble" a tiny bit when rotated. This may be the
problem, but I'm not sure how to correct it. I'll have to attempt
further disassembly at some point.

(This is just my luck with Eton products I guess. I had two high
serial number E1XM units with bad sync detector noise in USB/LSB
sync, and Eton declined to repair them, saying this was "normal,"
even though it didn't occur on two lower serial number units that I
tested.)

Regards,
Gary

Hi Gary,

Thanks for your question. I have four E100's (admittedly
quite a fanatic) but have never run across this problem. It
sounds like friction due to a misaligned tuning shaft. Have you
tried further disassembly of the radio, after taking off the
tuning knob? There is a very detailed file on dxer.ca
regarding E100 disassembly.
We would also be interested in the serial # of your E100, if
you could give it. To my knowledge, this problem has never been
reported in any of the "old" E100's (serial numbers before E10-

Eton E100 tuning via knob

Gary Kinsman
 

Hello all,

The tuning action on my E100 is smooth and precise over much of its
rotation, but it is stiff and mushy over part of its rotation. Is this
typical? Can it be fixed?

It's not the knob rubbing, because it happens with the knob removed,
and turning the encoder shaft with a thin screwdriver. I don't believe
my E10 has this problem.

I'm particularly interested in hearing from those of you with multiple
E100 units.

Thanks,
Gary


Re: Eton E100 tuning via knob

Gary DeBock
 

Gary,
 
     Eton has never been inclined to provide service manuals or other assistance to technicians seeking to repair or modify their own units.  All of what we know about the E100's internal circuitry was discovered by investigation and trial and error, including the alignment procedure, IF filter replacement procedure, etc.
 
     In general, the "old" E100's have a pretty good quality control record, but I have seen a defective stock loopstick, and a couple of new units with whip antenna wires broken off.  Eventually the E100 owners will have a detailed record of potential problems, and how to solve them.  If you can solve your tuning shaft problem by disassembly or lubrication, please let us know about your procedure.  Otherwise, an owner with an inoperative E100 might have a part you need, or you could track down a parts unit on eBay, usually very cheaply.

Hi Everyone,
 
Thought I would start my attempt at the Robert Ross Challenge of logging 300 stations in 30 days last evening . Thus far I  don't have a great number added to the list,  as I thought I would leave the commonly heards  for later on.
 
Last evening I concentrated more on logging some of the stations I've heard before but stations that don't come in that often, only now and then,  in case I don't have another shot at them  again within the 30 days.
 
I did manage to log 2 new domestics , one which I will be submitting for  a possible new graveyard frequency  distance record which will  outdistance my previous record by 500 miles or so.
