Gary,

I'd like to add my congrats as well. a DU on an
ultralight is phenomenal.

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

John H. Bryant <bjohnorcas@...>
 

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.

For those interested, the E100's replacement, the E1100, is available
in a Tecsun-badged version from Ebay seller "Trinityforevertrading".
The price is $12.99 with $13.00 shipping from Hong Kong.

Check out auction #250238926506 for an example of one of this
seller's auctions for the DR-920. The auction says this model is the
same as the Grundig G1100, which is the same thing as the new Eton
E1100. The seller says "we have a lot in stock".

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.

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!

A liitle OT: suggestion for antenna shielding

huelbe_garcia@...
 

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 :)

Re: Eton E100 "Equivalent"

Gary DeBock
 

Thanks Brett and John,

I just ordered a couple more of these feature-packed E100's,
thanks to your messages. The price is great, and Durham's units have
all come with the tunable loopstick, making full alignment possible.
After alignment according to the file recently prepared by John (with
minor help from me), the E100 should be tops in both sensitivity and
selectivity among the Ultralights, exceeded only by the SRF-T615's
low-band sensitivity.

Unlike the SRF-T615, however, the E100 has good resistance to
spurious signals in stock form, making it a good candidate for mega-
loopstick transplants. With 200 memories and class-leading
selectivity, I can't wait to see what it will do with a 21"
loopstick, hi.

new to ultra lite dx phenomenon

Carl DeWhitt
 

I have posted once on the dxer.ca forum but this is the first time
here.I bought a Sony SRF- m37v at the local Wal-Mart (for about $30) 8
days ago.It does not do too badly on sensitivity ,but it leaves
something to be desired on selectivity close to my local WBBZ-1230
kHz.At night,i dont notice as many images.I can dx stations 20 kHz
away from WBBZ at night but not in the day.I am currently trying to
decide whether to get a second M37 v to try audio phasing or go for an
Eton E100,the Sony T-615 and/ or SRF-59.I really want to get 2 good
ultralights to try audio phasing.I have been using the M37v barefoot
for the past 7 days.I have reached my goal of logging 100 stations in
a week on this radio by reaching 101 stations.I tried to reach 25
states in 7 days but conditions last night were not good with storm
static very loud on some channels.I got to 22 states in the 7 day
period.I will try to reach the final 3 states needed to meet this
challenge within 3 days.I have also logged 5 countries so far.They are
U.S.A.,Canada,Mexico,Cuba and Turks and Caicos Islands.After i have
reached my 25 state goal,i will try out the M37v with my
Select-Antenna.I will post some of my better loggings barefoot after i
have finished with my goals.Has anyone on here tried out
state/provincial parks(inland) for dxpedition sites? How about
mountain tops?I have been thinking of going to Oklahoma,s highest
point,Black Mesa(4973 ft.) for a ham radio qrp dxpedition mainly but
also trying some mw ultralight dxing in the area.Hopefully i can do
this in September or October when conditions are quieter.I plan to do
a little dxing at Great Salt Plains State Park(OK) in about 2
weeks.Good Dx to all !

Re: new to ultra lite dx phenomenon

Hi Carl:

Welcome to the craze! Many have the SRF-M37V, and with a new filter,
it really becomes a useful DX machine. If you have technical
abilities, the Sangean 455 khz filters available from RadioLabs may
be the thing - I know it really perked my M37V up.

If you've got the bucks, two T-615s would be an enviable set-up -
they are the overall stock sensitivity kings. Two E-100's would also
be great - their selectivity is the best that stock ultralights
offer, although make sure you get the type that can be aligned (i.e.,
the ones with movable coils on the ferrite), since they are better
sensitivity-wise up and down the dial. Check Durham Radio for one,
since those seem to be the movable coil type. I have an older one
that has a monolithic (and unmovable) coil on the ferrite: the high-
band sensitivity is the best of any ultralight, but it gets
progressively deaf as you move down the dial.

Re: Eton E100 "Equivalent"

Gary DeBock
 

Hi Gary and Kevin,
 
     Both the SRF-T615 and the E100 have image reception issues, but the E100's image problem is more severe.  On the E100, the image of local KSUH-1450 sounds almost as strong on 540 as the station does on 1450.  The SRF-T615 receives the same image, but at a reduced level.
 
     The SRF-T615, however, has more spurious and overloading issues, which are like poison to a transplant.  Spurious signals, mixing products and selectivity overloads are all magnified by a transplant, making the SRF-T615 a poor choice for a huge loopstick.  The E100, with the exception of its nasty image issue, has a very selective and generally well-behaved receiver.  As such, it would be a logical choice for a mega-loopstick, assuming that one doesn't have multiple locals 1440 and above.  As the most selective stock Ultralight, even with a huge loopstick, it would handle strong locals far better than the SRF-T615.
 
                                                                                    73,  Gary DeBock
