Re: Eton E100 tuning via knob
Gary Kinsman
Hi Gary,
toggle quoted messageShow quoted text
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

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 ... 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!! 73, Steve N5WBI Houston TX

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 Ron N8APZ

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, etc.) are inappropriate, as are various combinations (tape players/recorders + radio, MP3 players + radio, radio+flashlight, radio+Swiss Army Knife, etc.)" 73, Steve N5WBI Houston TX

Re: DT-400W Performance
Hello Joe and Ron,
Thank you both for the excellent links and
information on the new Sangean DT-400W model.
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 :>)
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!
73,

Re: Eton E100 tuning via knob
Gary Kinsman
Hi Gary,
toggle quoted messageShow quoted text
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.)

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,
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.

Re: Eton E100 tuning via knob
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
E10-0709xxxxxx).
