The Tecsun R-202T - In The End, A Turkey

satya@...
 

Hi all:

Giving the R-202T a good workout tonight, it showed its colors, and
unfortunately those colors bled into each other. Yes, it's got the
sensitivity and nulling ability of the R-911, images aren't too bad, the
audio is very good and it was well-aligned out of the box. However, the
barn-door selectivity is simply way too wide, allowing stations to bleed
into each other to a great degree. No, it's not as bad as some receivers
out there, but it wasn't the AM/FM-only version of the R-911 that I was
looking for.

On the plus side, I also ran its through its paces with a Crate Loop, and
the enhanced selectivity as well as signal gain when used with the Crate
made the R-202T really shine. Those looking for a minimalist DX machine
for this purpose might be interested in hazarding the grand sum of $2.08
for one of these.

I must congratulate the Hong Kong eBay seller, trinityforevertrading, for
getting it here in record time - 7 days from the time of order to showing
up on my doorstep. (I previously wrote that the seller was DPMega, but
they are slower to ship).

Hi Guys:

I have also sent tquchina an email expressing my concerns that the Orange Coloured R9012 he sent me was Inferior, and that I would much rather have one of the Black Cased Models. I asked him to email me back before I leave my Feedback on Ebay...to see what kind of solution he can offer to this problem. So.....we'll see what he suggests!! I told him if he sends us good radios.....he will sell a pile of them as word gets out pretty fast when a Good Product is being offered!! Nothing like a Happy Customer....and right now we ain't happy!! HAHAHA...

Film at eleven........or whenever I hear back from him!!

Update - Tecsun R-202T - First Look is Good!

satya@...
 

Quick sensitivity update: the WRX-911 is about as sensitive at the low end
of the band, but only if its FM/SW whip antenna is housed, against the
ferrite antenna. This doesn't make a whole lot of sense, but there you
go. The R-202T is less sensitive when the whip antenna is housed, as
would be expected.

There must be something about the 4", skinny ferrite antenna in the
WRX-911, which also responds differently to passive loops compared to
"normal" ferrites.

Kevin

Hi all:

In less than a week, Chinese eBayer "DPMega" delivered a Tecsun R-202T to
my house. This is a no-frills AM/FM set. It also touts itself as a
TV-band receiver because the FM band tunes down to 64 mhz. Really, it's
just your basic AM/FM receiver. It tunes from 525 to somewhere above 1600
from the factory. It runs about $2 plus shipping on eBay.

To my surprise, upon firing it up, it is noticeably more sensitive, and
has somewhat better nulls, than my tuned WRX-911!
TIS stations on 530 khz were mumbling-to-readable on the 202T, but just
mumbling on the WRX-911. High-band sensitivity appeared to be more
competitive.

The down-side is that the selectivity is broader than the WRX-911. For
instance, 730-Vancouver and 750-Portland are sandwiched between
uber-strong locals on 710 and 770, and the little 202T was not able to
deliver them, but the WRX-911 was able to get readable audio.

Upon voiding the warranty/popping the lid, there was revealed a tiny
2-inch ferrite, which makes me wonder how the heck the sensitivity is so
good! It has the same split-coil arrangement as the 911. It also has the
same 4 alignment set screws as the 911. The PCB board was much smaller
than that of the 911 - not a whole lot going on without the shortwave
bands.

Not sure if a cheap narrower filter could be put in, although the little
PCB board seemed reasonably easy to work on. Without actually removing
the board, I'm pretty sure I can see a discrete filter.

There are two switches (power and AM/FM) which pop out with the case,
which means that if you had it open for an alignment, you would have to
jumper those two switches to get it to work, but it looked pretty
straightforward. I managed to get it back together with no problem, which
really says something...

In all, one of the best $2 I have spent recently. If this little guy took
a new filter, it would really be a terror! (Anybody with tech skills want
to take a look??)

New Department heard with ULR

Horacio Nigro <hanigrodx@...>
 

Not to compare with the distances involved in the US geography, but in my personal case it may be worth of mention that I've set myself the goal of listening to the total of 19 Departamentos Uruguay, my country, has.

In the 1970s my local DX Club, used to extend a certificate that was named "Curuya Oriental" I will explain this: Curuya spelled as koo-roo-yah, is the ham term used to name BCL's or SWL's. It comes from the word "coruja" which in turn comes from the Portuguese language, and is the popular name for the Owl, so highly and historically connected with ham radio, and specifically DXing. The "verb" "curuyar" is used as "to listen to" in the Southern South American ham radio argot. And "Oriental" is the adjective for us Uruguayan citizens, since we live in the República Oriental del Uruguay (the country's official name which prior to the National Independence was self named "Banda Oriental", i.e. the territory located at the Eastern side ["Banda"] of the Uruguay River.

Well, unfortunately the DX Club del Uruguay no longer exists, and I can't apply for the "Curuya Oriental" certificate which remains in the sweet corners of the memory. But the ULR mania has given a revamped chance to try for it. I don't known if it would be 100% possible, and complete the 19 total number, but we are in the trail...

Here's the ULR log today:  URUGUAY. 1580 CW158 R. San Salvador, Soriano, 0930, timepip and ID: "A-M Mil Quinientos Ochenta, Radio San Salvador". =14th Departamento of Uruguay.=

Re: Kaito WRX-911 1st Impressions

satya@...
 

Hey Jeff:

Welcome to Club 911! Let us know how the alignment goes - it should make
it perk up, especially on the low end of the band. I too have been
impressed by the audio, although the Crate Loop makes the audio distort a
bit on certain stations, given the huge increase in gain.

In all, it's quite a little radio.

Kevin S
Bainbridge Island, WA

My WRX-911 arrived yesterday morning from J&R and so far I'm quite
impressed. First, the audio from the speaker is much better than I
anticipated, on a par if not better than my Eton e100. Second, the
Shortwave reception is pretty darned good. Just OK off the whip
antenna, but with a 30 ft. longwire clipped on, it totally comes alive,
no overloading. The 60 meter band was especially good last night here
in Wisconsin - again the WRX-911 performed on a par with my Eton e100.
I should also mention I was listening from my office which is in the
basement of a concrete reinforced building.
Medium Wave reception much the same as shortwave. Barefoot not bad, but
with the aid of my Crate loop it wakes up this little radio big time.
The tuning light is a great aid when inductively coupled to a tuned loop.
So far so good, I'll be checking the alignment sometime soon but it seems
to be pretty good out of the box. For a radio priced at $14.99 +
shipping - I'd rate it outstanding. Just ordered another from J&R as
gift to my nephew!

Awards Program Report

John H. Bryant <bjohnorcas@...>
 

Friends,

I've had serious computer woes for almost three weeks, finally diagnosed as an intermittent hardware fault in the portion of the CPU that works with the video board. Although all of the records and awards were backed up, some of my type fonts were not and the actual processing of the awards certificates has been on hold for that entire period. I was finally able to scavenge enough off the sick computer's hard drive that the award certificate processing is back in operation. I'm pleased to join the rest of the Awards Committee in recognizing the following truly outstanding Ultralight MW DXing accomplishments:

Horacio Nigro
         Five Countries Heard,  Barefoot Class
Long-time DXer, Horatio Nigro of Uruguay is out first South American DXer to receive an award... given his past achievements, I suspect that we will be calling his name quite a bit. We were also pleased to note that Horacio is going to be working to interest other South American DXers to join the Ultralight Community.

Frank Welch
        60 Graveyard Stations heard, Barefoot Class
Frank, long active in amateur radio has gone up the ULR stations heard ladder rather quickly and is only the second person to reach the 60 Graveyarders Heard level (Rob Ross did it in the Unlimited Class.)  Congratulations, Frank on being the first of us to accomplish this difficult DX achievement, BAREFOOT!

Richard Allen
        600 Stations Heard, Barefoot Class
Although Rob Ross is the only other ULR DXer to reach the 600 Station level, Rob switched to Unlimited Class at about station 501, so Richard stands atop the heap of Barefoot Class DXers, now being well beyond 600.  Richard accomplished this in something like 11.5 months of DXing. BRAVO!!!

Chris Knight
          4 Canadian Provinces Heard, Barefoot Class
           5 Latin Stations Heard, Barefoot Class
          10 US States Heard, Barefoot Class
          20 US States Heard, Barefoot Class
Well known MWaver Chris Knight of suburban Denver is just getting started in Ultralighting, but has already garnered some outstanding DX. Chris, we are really glad to have you aboard and let us know as you reach goals!  Loggings are welcome, too.

Kirk Allen
        10 ULR Countries Heard, Unlimited Class
         70 Latin Stations Heard, Unlimited Class
         500 Stations Heard, Unlimited Class
         Master Ultralight DXer, Unlimited Class
Kirk has been laboring mightily to reach all three of these goals and I really don't know which one is the most difficult.  I never thought that anyone would hear ten countries from northern Oklahoma, but I also did not think anyone would accomplish either of the other two. I know that Kirk feels like many of us.... its great to start over with a clean log book.... but now Kirk, the log book is no longer empty and things get REALLY difficult!  Great going, podner and all of us forgot about the Master DXer award coming at 500 stations, too!

Dianne Froude
          Trans-Atlantic DXer, Barefoot Class
           4 Continents Heard, Barefoot Class
          20 Countries Heard, Barefoot Class
          100 Stations Heard, Barefoot Class
As many of you know, Dianne is (we think) our first female Ultralight DXer and is also relatively new to MW DXing itself. She is obviously learning quickly to take advantage of her location in St. John's Newfoundland. The awards above certainly attest to her fitting into this hobby in a big hurry. Soon after Dianne joined the ultralightdx group, Richard Allen spotted a wonderful magazine cover (Radio News, June 1923) that seemed very appropriate for a special award for any female DXers. Yesterday, Dianne received the four standard awards, featuring the beautiful Eggers painting of the God of Radio and she also received a special version of the Trans-Atlantic Award with the alternate graphic, featuring a lady DXer from the early 20s. A reduced, very low resolution of that award is inserted below.



John Bryant
          70 Latin Stations Heard, Unlimited
I was trying my darndest to beat my DXing buddy of 25 years, Kirk Allen, to 70 Latins heard, but he beat me by five or six days.... I did sweep past him and thought that I had gotten to 80 before him.  Then I checked my loggings carefully and found two duplicates!!!  So, I went back to work - this is getting hard - and landed another two in about four days or five.  I checked everything over very carefully and submitted my loggings to Rob this morning. I just heard back from him that I had missed one duplicate and only have 79!!!!  ARGGGGGGH!!! Oh, POO!

CONGRATULATIONS TO ALL OF THE FINE ULTRALIGHTERS ABOVE.  WELL DONE!!! And Rob DOES check these things, you know.

John Bryant,
for the Awards Committee

Sounds like tquchina has an initial bad batch of
Tecsun R9012's in orange. Otherwise, he is a fine
vendor to deal with, I've purchased 3 radios from
him in the last year or so.

I like the pictures of the radios he provides on
his eBay site, very thoughtful.

I emailed him today to change yesterday's R9012
radio order to a different color. I also ordered

Re: SRF-59 alignment

Jay Heyl
 

Well, I'm afraid the alignment of this SRF-59 did not bring it up to the expected level of performance. I was able to pull the low end back down to where it should be in the tuning range. Unfortunately, the antenna coil hit its limit of travel before it clearly peaked. The coil ended up about 1/16" off the end of the ferrite. There is an ESPN station on 540 that I can get in decently on the previously aligned SRF-59 and also on my factory aligned E100. This second SRF-59 gets very marginal reception on that station. Since the coil was already off the end of the ferrite I figured that was the best I could do.

It's definitely better than it was, but still far short of what my other SRF-59s can do. I guess this one is a dud.

Hi Jay,
 
The SRF-59 has two adjustments to set the AM frequency limits-- the uppermost trimming capacitor on the back of the tuner (to set the high limit, usually to 1750 kHz) and the red-slugged transformer can next to the loopstick (used to set the lower limit, usually to 520 kHz). Whenever the dial frequency is far different from the tuner frequency, you will need to adjust both, to get the radio working properly.
 

Thanks, Gary. I'll give it a go.

Tecsun R9012 Lemon Variants-- More Info

Gary DeBock
 

Hello All,
 
Rob Ross and I have both received yellow/ orange colored R9012 analog models from the eBay seller "tquchina," which have proven to be substandard in comparison to the black R9012 models from "dpmega." The lemon models have very poor AM performance out of the box (typically receiving only two or three locals), and cannot be aligned up to the sensitivity level of the black R9012's.
 
Further investigation reveals that all the lemon models received so far were made in 2005, and have a serial number of 0892005xxxxxxx. The Tecsun R9012 date of manufacture is actually stamped on the circuit board, below the loopstick mounting position (but usually hidden with tape).
 
In addition, the loopstick coils and coil forms are different in the "good" black models, manufactured in 2008. Tecsun has apparently improved the AM sensitivity in the more recent R9012 models, but the substandard (at least on AM) R9012's from 2005 continue to be sold.
 
For those of you performing an R9012 alignment according to the pictorial just posted on DXer.Ca and the Yahoo groups Ultralightdx and ODXA, please note the date of manufacture stamped on the circuit board below the loopstick position. If your R9012 was manufactured in 2005, you may have a lemon, and may not be able to get frequency coverage from 530-1700 kHz, or bring up sensitivity to a high level.
 
Tecsun R9012 purchasers are requested to check the serial numbers, and report lemon models ASAP. In the interim, please avoid purchasing any R9012 models from the eBay vendor "tquchina."
 
73, Gary DeBock
