ULR DXpedition in South Africa

John Plimmer <plimmer@...>
 

John Plimmer, Gary Deacon and Vince Stevens have just come back from their
Seefontein DXpedition site.
See: http://www.dxing.info/dxpeditions/seefontein_2005_07.pdf
This old site describes the location of this excellent DX location.

John had his E100 with him and managed to get his barefoot count up from 19
countries to 27, but try as he might he just could not get the little E100
to get 720 ABC Perth to take his continents barefoot count up from five to
six. Of course I stuck the little thing in the Kiwa MW Loop and that did the
trick, but that would push me into the "unlimited" class where I don't want
to be.

I don't know how Vince did, I hope he will report soon.
Gary spent hours twiddling his little Sony and has got some astonishing
results. I don't want to report for him, so hope he will report himself
soon.
Come on Gary - we are dieing to see your results...........

Ultralighting is sure a lot of fun, and all three of us could tear ourselves
away from the big radio's to enjoy the fun on the ULR's.

Hi Glenn,

The call was changed from CHWO to CFZM some time ago.

Re: Tecsun R911 has arrived

It's a shame there is no verified comparable performer from this
group of Tecsun ultralights that has an digital frequency-counter
display. My own experience with (and reading reviews of) earlier
models has not been encouraging - going back to the R919 that was the
first to be rebranded by Grundig-Eton.

The equivalent model from recent years would be the Tecsun R-9702
(pictured in the Tecsun family tree photos posted recently). I own
one of these, and while it isn't quite in the same "turkey" category
as some of the others, its MW performance really doesn't seem to even
be in the same league as the 911.

The station I was on -- 610 was the closest I could get -- definitely got stronger as I moved the coil toward the end of the bar. I just couldn't move it far enough to get past the peak, so I'm not sure if I've really peaked it or not. But short of physically cutting the coil form or cutting bits of plastic out of the case, the coil can not be moved any further toward the end of the bar. I've hit the limit of travel and there's no place left to go. I guess what I'm saying is it's as good as it's going to get. Whether that's the best it could be or not is kind of moot. Still bothers me a bit though.

I did go back and forth a couple times. Mostly I spent more time digging out wax with a dental pick to allow the form more travel on the bar. After clearing out more wax and moving the coil a wee bit I did need to re-peak the 1400kHz trimmer.

Re: Tecsun R911 has arrived

Another trick I stumbled on to determine if I went out too far and missed
the peak is to bring another ferrite (a spare 4 or 8-incher) in close to
the receiver's loopstick. If at some point it adds enough inductance that
I get a peak, I realize that I slid the coil off too far.

Maybe worth a try? You should be getting a peak.

Hope this helps- Kevin

Likewise, after doing the loopstick coil on 600, the TIS stations on
530
seemed a little weak, so I aligned it again at 530. after a
micro-nudge
of the coil, 600 still came in just as good, but 530 was now much
better.
This bothers me a bit with the one I have. I moved the coil as far as it
would go toward the end of the ferrite bar and never heard the station I
was
on getting any weaker. I have no idea if it's truly adjusted properly.
Since
I've hit the physical limit of travel I guess there's not much I can do
anyway. My only option would be to trim away some of the form that
sticks
out from the coil. That would get me maybe another 1/8" of travel.
Probably
not worth the risk of damaging the coil.

Re: Tecsun R911 has arrived

Hey Gary/Jay/all:

The 1400 khz trimmer was the culprit for me as well - it really perked up
after that. Like Jay, I probably gave it a good quarter turn from where
the factory had it.

As it turned out, peaking it by ear on 1400 seemed to leave a bit to be
desired at 1700, so I aligned it again at 1700, which required a very
small tweak of the trimmer. This still preserved what sounded like a
maximum signal on 1400, but just the little tweak made all the difference
at the top of the band.

Likewise, after doing the loopstick coil on 600, the TIS stations on 530
seemed a little weak, so I aligned it again at 530. after a micro-nudge
of the coil, 600 still came in just as good, but 530 was now much better.

So, it could be that the extreme frequencies need a little tweak that my
ear doesn't catch on 600 and 1400, and that aligning at the extremes (at
least on this radio) is the way to go. I would be interested to hear if
you or anyone else gets any improvement at either end of the band doing
this!!!

Kevin

Hi Jay,

Congratulations on the successful AM alignment of your Tecsun R911, and
I'm
sure you will notice a nice performance boost after peaking the
loopstick,
and 1400 kHz trimmer.

The whip antenna connector wire on the WRX911 and R911 models breaks off
with very little provocation, so hobbyists are advised to remember this,
when
separating the front and back sections of these portables. The same
warning
applies to the Eton E100, another Tecsun-manufactured model.

The Tecsun R911 models apparently already have the upper AM frequency
limit
set fairly close to 1700 kHz according to your description, Jay. The
R9012
units are quite different, typically going up to about 1650 KHz before
the dial
hits the upper limit. Fortunately, the tuner's trimming capacitor can
always
get them up to 1700 kHz, without disturbing coverage of 530 kHz on the
lower
end.

73, Gary DeBock

So far, every one of these Chinese analog portables has gained a
significant
AM performance boost when alignment (loopstick peaking and 1400 kHz
trimmer
adjustment) is performed. Out-of-the-box performance is typically not
near
the optimum capability.





Today I aligned both my modified SRF-59 and the newly arrived R911. The
SRF-59, as expected based on performance, was already very close to
optimum. The
antenna coil ended up pretty much where it started. The trimmer I moved
just
the tiniest bit.

On the R911, the coil form was REALLY waxed onto the ferrite bar. I was
digging out wax for probably 20 minutes. It even extended considerably
under the
bar. I ended up using a dental pick. Even after the coil was free, I
still
had to remove more wax because it was built up on the end of the bar and
I
couldn't slide the coil as far in that direction as was needed.

The coil did end up being moved almost a quarter of an inch.

The radio already tuned to 1690 straight from the factory. I can't get
anything on 1700 during the day time here, so I adjusted it to provide a
bit more
travel beyond 1690. Incidentally, I had to turn the screw clockwise to
extend
the tuning range, not counter-clockwise as indicated with the photos. I
had
to revisit this adjustment after getting everything else adjusted.

The 1400kHz trimmer adjustment was pretty far off. I must have gone
almost a
quarter turn before getting it peaked.

While trying to get the wax off the coil form I manged to stress the whip
antenna connection and it broke right above the solder on the circuit
board.
Fortunately, the soldering iron from my old days doing Heathkit projects
was
still here so I was able to put my crude soldering skills to work.

After getting everything put back together and removing as much of the
wax
as I could from the outside of the case (that stuff was everywhere), I
gave it
a quick try. MW sounds pretty good, but I noticed the volume on FM,
especially on distant stations, seems to be greatly reduced. I don't know
if I
accidentally bumped something I shouldn't have or if my poor soldering
skills are
showing. SW is still coming in fine, so I have to think the antenna
connection
is okay. No biggie. I didn't buy this radio for FM.

Now that both the SRF-59 and R911 have been tuned up, I will try to do a
detailed comparison tomorrow.

On a related side note, I've used a number of very small screwdrivers in
these recent radio projects. My father had a cheap set of tiny
screwdrivers, one
of which I turned into something that looked more like a twist bit than a
screwdriver. Another one of the set had previously been given a similar
treatment. So I went looking for a decent set of screwdrivers for tiny
screws. I was
very attracted by a Wiha set I found on Amazon, but $30 delievered seemed
a
bit much for something I wouldn't use all that often. I ended up with a
Husky
set (HD-74501) of interchangeable bits along with a handle. The unmounted
bits fit snugly into the hollow handle. $6 at Home Depot. I bought one
set to
replace the cheap set my father had and another for myself. They seem
quite
nice and I'm pretty sure the bits aren't going to twist all out of shape.
And
even if they do, there's a lifetime warranty.

I've seen three variations on these small screwdrivers. There are really cheap ones where the bits have round shafts and are compression fit into holders. This is the kind my father had. I used to have a set like this. These are junk. You aren't saving money by buying them because you'll be throwing these away and buying a better set the first time you use these on a stubborn screw or apply a bit too much torque (which isn't much). Either the end of the bit will twist or the whole bit will fall out of the holder. Harbor Freight has at least one set like this for $3.

There are slightly more expensive ones where the bits are made of much better steel, have hex shafts, and are probably reversible. The Hefty one I recommended is like this. Harbor Freight has at least one set like this also.

Then there are the really good ones like the Wiha ones I mentioned. The blades are hardened chrome vanadium steel and have dedicated, molded on handles. If you like top quality tools, I'm sure these are a joy to use. I'd love to have a set, but just can't justify spending $30 on it.

Sorry for the diversion away from purely radio, but if you plan on tweaking your ultralight you would do well to invest a few dollars on some precision screwdrivers. They come in handy for opening the cases, adjusting the trimmers, and even for scraping away the wax holding the coil form to the ferrite.

Re: Tecsun R911 has arrived

Gary DeBock
 

Hi Jay,
 
Congratulations on the successful AM alignment of your Tecsun R911, and I'm sure you will notice a nice performance boost after peaking the loopstick, and 1400 kHz trimmer.
 
The whip antenna connector wire on the WRX911 and R911 models breaks off with very little provocation, so hobbyists are advised to remember this, when separating the front and back sections of these portables. The same warning applies to the Eton E100, another Tecsun-manufactured model. 
 
The Tecsun R911 models apparently already have the upper AM frequency limit set fairly close to 1700 kHz according to your description, Jay. The R9012 units are quite different, typically going up to about 1650 KHz before the dial hits the upper limit. Fortunately, the tuner's trimming capacitor can always get them up to 1700 kHz, without disturbing coverage of 530 kHz on the lower end.

So far, every one of these Chinese analog portables has gained a significant AM performance boost when alignment (loopstick peaking and 1400 kHz trimmer adjustment) is performed. Out-of-the-box performance is typically not near the optimum capability.
 

Today I aligned both my modified SRF-59 and the newly arrived R911. The SRF-59, as expected based on performance, was already very close to optimum. The antenna coil ended up pretty much where it started. The trimmer I moved just the tiniest bit.

On the R911, the coil form was REALLY waxed onto the ferrite bar. I was digging out wax for probably 20 minutes. It even extended considerably under the bar. I ended up using a dental pick. Even after the coil was free, I still had to remove more wax because it was built up on the end of the bar and I couldn't slide the coil as far in that direction as was needed.

The coil did end up being moved almost a quarter of an inch.

The radio already tuned to 1690 straight from the factory. I can't get anything on 1700 during the day time here, so I adjusted it to provide a bit more travel beyond 1690. Incidentally, I had to turn the screw clockwise to extend the tuning range, not counter-clockwise as indicated with the photos. I had to revisit this adjustment after getting everything else adjusted.

The 1400kHz trimmer adjustment was pretty far off. I must have gone almost a quarter turn before getting it peaked.

While trying to get the wax off the coil form I manged to stress the whip antenna connection and it broke right above the solder on the circuit board. Fortunately, the soldering iron from my old days doing Heathkit projects was still here so I was able to put my crude soldering skills to work.

After getting everything put back together and removing as much of the wax as I could from the outside of the case (that stuff was everywhere), I gave it a quick try. MW sounds pretty good, but I noticed the volume on FM, especially on distant stations, seems to be greatly reduced. I don't know if I accidentally bumped something I shouldn't have or if my poor soldering skills are showing. SW is still coming in fine, so I have to think the antenna connection is okay. No biggie. I didn't buy this radio for FM.

Now that both the SRF-59 and R911 have been tuned up, I will try to do a detailed comparison tomorrow.

On a related side note, I've used a number of very small screwdrivers in these recent radio projects. My father had a cheap set of tiny screwdrivers, one of which I turned into something that looked more like a twist bit than a screwdriver. Another one of the set had previously been given a similar treatment. So I went looking for a decent set of screwdrivers for tiny screws. I was very attracted by a Wiha set I found on Amazon, but $30 delievered seemed a bit much for something I wouldn't use all that often. I ended up with a Husky set (HD-74501) of interchangeable bits along with a handle. The unmounted bits fit snugly into the hollow handle. $6 at Home Depot. I bought one set to replace the cheap set my father had and another for myself. They seem quite nice and I'm pretty sure the bits aren't going to twist all out of shape. And even if they do, there's a lifetime warranty.

Re: Kaito WRX911 AM-FM-SW Ultralight-- A Real Tiny Wonder

Horacio,

I purchased my Kaito WRX-911 from a dealer inside the
USA. It tunes 530 to 1710 kHz. I have seen the Tecsun
versions (R911) listed on eBay, but, as you indicate,
they only tune to 1610 kHz. It must be that the Kaito
version I purchased was intended for the US market.

Here is the link to the vendor from whom I purchased my
WRX-911:
