Photos of National SRF-39

The one photo that I inserted in a recent message about completing the National SRF-59 got stripped out of the message before it got to some of you, but reached others... So, I've uploaded another gallery of photos to the Photo section of our group web page. Its http://ph.groups.yahoo.com/group/ultralightdx/photos

Re: Eton E100 "Equivalent"

John H. Bryant <bjohnorcas@...>
 

I just got another one of those, too, Brett.... I wanna have a back-up.  There are several E100s, new in the box on ebay right now. The going price is about $50.  I suspect that the supply will be soon exhausted.... it is such a good little radio.

Given the dwindling supply, are there any "equivalent" current Grundig/Tecsun models that might also be contenders for this class of radio?

Very interesting, Huelbe.... and not off topic at all!

Hello,
 
there are a few sources relating the pros and cons of using a shield over the loop antenna.
 
However, some time ago I found an original way to shield a ferrite loop, it was made by PA2OHH Onno for his Navtex (518KHz) receiver: http://home.hetnet.nl/~pa2ohh/07fer.htm
 
Onno used a flat, multi-wire cable (like those used with hard-disks) to build the shield.
 
Perhaps one can make a try in an ultra-light or not-so-light receiver :)

Final National SRF-39 Photo

John H. Bryant <bjohnorcas@...>
 


I couldn't resist sharing one of the photos that I took yesterday of the final National SRF-39 in its cabinet and with its companion speaker system cabinet. The sound system is a small 2 x 5 watt stereo amp from canakits  (canakit.com) that cost under $35 assembled. It runs on 12VDC.  The back panel of the audio box has an audio out for two larger outboard speakers and a switch to choose between the outboard speakers or the four little speakers (2x2) in the front panel of the box. Thanks to canakits, the front panel has two input ports (hi and low impedance) as well as the volume pots for each channel and a power switch. Instead of putting both the radio and the speaker system in the same box, I opted for this route because I didnot have enough scrap wood for the larger cabinet and, this way, I can leave the speaker box in the NW, since my only use for this set in Oklahoma is DXing.





The ports for the four speakers were determined by the size of the little tweeters and mid-range units that were salvaged from the iPod audio dock that I salvaged. I kind of like the appearance of the speaker unit as it is very like some of the amps and receivers from the mid-1920s, when you had to watch the brightness of the tube filaments as you adjusted the controls. In any case, the speaker box will look good in my shelves, whether it is being driven by the National SRF-39 or by my mp3 player.

I'll be submitting an article this week, I hope.

And before either Nick or Guy can say it, YES, its great to be retired... the only problem with it is being OLD!

That was a good spot, as usual, Guy.... Despite the poor review, I ordered one.... I've been wanting to learn about substituting filters.... and VERY inexpensive for a digitally dialed radio... Time will tell.

Check out auction #250238926506 for an example of one of this

The price certainly is low enough to be painless, in case this model
turns out to be a dog! Perhaps we ULers will get lucky and find this
to be a nice model.

I wasn't aware that an ultralight is defined as less that 20 cubic
inches in mass, and with a single bandwidth, until John Bryant
pointed it out recently. This Tecsun/Eton/Grundig model fits both
requirements with a 15.19" cubic inches measurement, and a single
bandwidth.

Dennis, Rob and Allen,

Thank you all very much for your
congratulations on the 531-DU logging.
Unfortunately, the west coast DU experts all say
that there are at least
two good possible Australians on the frequency, and
even a New Zealand
possibility. Since there was no ID heard (only
repeated music, with no voice
breaks), the station will remain an "unID" until
somebody (hopefully me) receives it
again on an Ultralight, and hears a positive ID.

Actually, I'm quite happy to have shown that
Ultralight radios are
capable of breaking the "DU barrier." Sooner or
later one of the "Northwest
Gang" (or maybe a lucky DXer elsewhere) will have a
solid ID on an Australian,
and I'll be the first to congratulate him. Nick,
Guy, Dennis and Steve all
are very capable and experienced in DU DXing, and
all have a great chance to
hear the first Aussie ID on an Ultralight. John B.
is also coming back to
Washington, and is sure to try his luck. Good
luck, guys!

Re: Tecsun DR-920 (aka Grundig G1100/Eton E1100) Cheap on Ebay

Guy Atkins
 

Hi Huelbe,
 
Well, that is disappointing. It sounds like Eton/Grundig is going backwards, if they are just rebadging a year and a half old radio.
 
However, perhaps the sensitivity is just a matter of inaccurate out-of-the-box alignment, and can be fixed by following some basic steps such as Gary DeBock has described. Even many of  the popular SRF-59 radios have not been well aligned from the factory.
 
Hopefully the selectivity can be remedied with a replacement filter, although it may be more effort than it is worth, on such an inexpensive radio.
 
BTW, the auction number I listed at first was wrong. The correct Ebay auction item number to check is: 370045350485. Or, you can just search for all auctions by "Trinityforevertrading".

Hello Guy, friends.

When you said "DR-920" I immediatelly thought, "oh no!"

I have checked the site: DR-920 is physically the same G1100 receiver from
Grundig/Eton site. An search though Internet came a few pics of E1100,
identical to G1100.

About DR-920 I bought one about 1.5 years ago and now it's my dad's radio
:). It's full analog, has a frequency meter and clock. It's not PLL/DDS. Its
sensitivity is weak to poor, but its selectivity is horrible! You can listen
a strong station as far as 30 khz away from its nominal frequency. Still,
it's a nice gift for your dad who listens only to local hard-news stations
:)

So, assuming DR-920 = G1100 = E1100 (and I am confident they are the same
receiver), I don't think they are a replacement for E100.

Richard,

Great going with the SRF-59. The KCBS logging at 1500 miles with KTRH Houston and KRMG, Tulsa as QRM is particularly fine.  I imagine that Tulsa protects Houston and vice versa, so Tulsa might not have been much of a problem, but I bet that Houston was.

Keep up he good work.
