Keith, you might try out the smallest conventional, analog (not USB) powered computer speakers from Logitech; under $12 in Walmart here on the ConUS. They're dark gray-black, have an AC cord that leads directly into the left speaker (no wall-wart) and have no hum when output from netbooks, ULRs and my ATS-909. They feel solid, sound very good to me and are inexpensive and uncomplicated.

Hi Keith:

The digital Sony model is probably the SRF-M37W. It is fairly sensitive and has great sound through headphones (IMHO), but it has quite broad selectivity and issues with images, so not necessarily the best Ultralight for urban areas. However, Allen Willie in Newfoundland exclusively uses one, and has heard a jaw-dropping amount of DX with it. It is covered in the Shootouts and Gallery in Folder 1 - Start Here" in the Files section here on the Group.

As for speakers, I have found many little add-on speakers are quite noisy, either because they have a wall adapter that gives off a lot of RF noise, or the component in the amplifier circuit are noisy. This includes speaker designed for computers. I found a little set of speakers with no amplifier - just the speakers - and they work pretty well. They will not fill a room with sound, but are serviceable, especially next to my head as I drift off. I don't believe the M37W or many other Ultralights have sleep timers, although the Tecsun PL-300/310/380 and others have a timer.

Hope this helps - Kevin S

Dear Kevin

yes ferrites on the outside ends using two sides sticky tape, 3 tapes per end

hole to be drilled out each end to take the pickup ferrite rod  (3 amidon 1/2" by 8" rods in series)

so flat ferrites on top each end and pickup in the middle

Robert,

Thanks for the welcome. DXing is going to be a bit of challenge here. I have 19 local AM broadcast stations within a 20 mile radius of me! I don't believe any of them are required to observe day/night power variation or quiet hours. Fortunately the SRF59 has a very deep null. Digging through my junkbox I found a 4.5" ferrite core that I rescued from an old radio may years ago. I will probably use that to make a tuned passive coupler. I'm more inclined to believe I need more in the way of interference rejection than in added sensitivity.

Hello Bear:

    Welcome to the ULR Group!!! You may very well be our first member from HAWAII!!! You are in an IDEAL SPOT to hear a lot of Wild DX from all directions!!! You will be happy with the SRF-59...it is an amazing little DX Magnet. It's the Radio I started ULR DXing with in JAN 2008. I have now switched over to mainly using an SRF-T615 (Have 3 of these little Buggers)!!! I logged over 300 Stations in the first 30 Days of ULR DXing...using the SRF-59. After 3 Years I am sitting at 929 Stations heard on a ULR!! So..the sky is the limit.....as long as you devote time and effort to DXing with ULRs. Many of the list members have proven that distances of 5000 Miles Plus are VERY POSSIBLE with ULRs...and your location with WATER EVERYWHERE...should prove interesting!!

Let us know what you hear...we can hardly wait!!!

Have Fun with the ULRs.....and again, welcome to the Group!!!

Re: New Sangean DT-400W

Fine business Keith, I find no fault with your thoughts on these subjects because basically they have been my experience also.

With the exception that the DT-400W is much more pleasant to listen too than the DSP-equipped radio's. It sounds more like a very strong analog radio with all the nice features of a digital radio. I think that is why the costly Sony SRF-T615 is so popular. By the way if you get a turkey radio, well you give it to one of your kids and go back to what works best, probably a trusty old SRF-XXX.

One of my favorite radio's is the very analog 1978 Panasonic RF 2200, of course it is an uber sized radio not an ULR. No freq counter on this baby!

I have to say, digital tuning makes finding stations easier; and the DSP-equipped Chinese radios really can pull in those weak signals (although I haven't had time to do any serious DXing in some time).

Indeed, have the flat ferrites now (100mm*3mm*20mm) but looking for a large
diameter plastic tube dia => 12" to about 20".
This follows directly from Steve's assertion that a large diameter is needed
following his experimental evidence posted in this group.

Will place ferrites on each end and wind the contra-winding as per the
Polydorroff patents and will be the ~ 1/4" off ferrite surface.
This is the kind of plastic form I am
consideringhttp://www.usplastic.com/catalog/item.aspx?itemid=23849&catid=459

a grounded cage variable capacitor will be used to resonant.
pickup will be via a ~ 24" ferrite rod ( 3 * 8"by 1/2" dia 61 material Amidon0
this will have a contra-winding upon its surface (distance of wire to ferrite
surface ~ 1/4")
The idea is that placing this rod in the centre the mutual coupling will be such
that it is weak and therefore will not upset the Q of the main tuning circuit
yet enough signal for a sensitive radio.

Guess I have to give in :-) I only have a SRF-59, G8 and a PL-380 in the uldx range
and am rather fond of the cuteness and sensitivity of the SRF-59. It smiles smugly next to my
ancient
Barlow-Wadley on the shelf... It´s lower sensitivity than the DT-400W is presumably due to the
shorter internal ferrite antenna. Inductively coupling a longer tuned rod makes a big difference, of
course.

Hi Ginger, nice to make your acquittance. you can get the SRF-59 at K-Mart for 14.95. It is a very good little radio and you will catch a lot of DX with it. The Kaito looks like a good one, a lot of the Chinese radio's are marketed by Kaito.

Just spent the last two hours listening to a high school baseball game on a station just a little above the static level on my SRF-59. When I listened to it on my DT-400W it was twice as loud and a much more pleasant experience.

Therefore the SRF-59 gets no cigar in that respect. However, cross station modulation is a different story. Here the SRF-59 has a small advantage.

All that having been said, analog is good but digital is better! :-)
