Re: 531 kHz UnID-- Ausralian Assistance Needed (Again)

Hi Gary, The weather report and its presenter sounds much like the very detailed reports given on 4KZ. I could only conclusively identify 'showers and thunderstorms' and 'SE winds', a common forecast

Found a ton of Japan market ultralights on ebay

Looks like this guy has found a ton of them: https://www.ebay.com/usr/fixit-ez I emailed him asking for recommendations and he was helpful.

Re: New style FSL Part 2

Thank you for your reply Dean. Very interesting about the flux concentration. Keep at it. Looking forward to seeing what you find. Bill

Top Ten Asian Blasters in Hawaii

Asian propagation is obviously enhanced in Hawaii-- not to mention DU propagation, South American propagation and that from many other areas. The "big gun" blasters are different from the Japanese and

Re: New style FSL Part 2

Thanks Gary : BTW i don't feel like anyone was giving me grief about these new loop's ,And honestly my goal was just to see if there was any advantage to the basket weave design that I had been

Re: New style FSL Part 2

Basically the same as the G Maynard "Spiral Loop with Q Multiplier" from the 1980's, with ferrites added. :^) His design was balanced, with a centre tap half way up the windings which went to the

Re: New style FSL Part 2

Hello Dean (and Bill), Thanks for your interesting experimental contribution, Dean, which certainly breaks new ground in FSL antenna design. As a veteran of multiple FSL design controversies after

Re: New style FSL Part 2

Hi : Sry i cant be more help here ? The number of winding's will depend on the value of capacitor you use and what Frequencies it will tune. Dean W.

Re: New style FSL Part 2

Hi Bill; Nope the nulls are very sharp, in fact much sharper than my regularly wound FSL's . as far as a distorted pattern I haven't seen that . These loops have a figure -of -eight pattern ,gain is

Re: Junk ferrite cores

Hi Mike If I recall correctly the ferrites used for EMI suppression on data cables are designed to be lossy. In otherwords the RF energy travelling along the cable should turn to heat in the

Re: Hello and Sony SRF-S14

Hi takane2, Your ICF-S14 indeed looks like ultralight size. To me it looks about the size of my Sony ICF S10 MK2. Welcome to the group. Happy DXing! Bill Arizona

Re: New style FSL Part 2

How many feet of litz wire did it take to wind this antenna? How many times around the form did you wind? Thank you!

Re: Hello and Sony SRF-S14

Shoot, I meant ICF-S14 not SRF. Sorry I got the model numbers mixed up with the Sonys.

Hello and Sony SRF-S14

Hello, I just joined this group. I don't think I have anything that qualifies as ultralight yet. I have a Grundig FR-200, Grundig G4000A(the last of the YB400 models) and a unbranded 70s era Japanese

Junk ferrite cores

People keep upgrading their PC monitors, and a lot of monitor cables are being thrown away. First VGA, and now DVI. Many of them have EMI suppression ferrite cores of various sizes. They come

Re: New style of FSL........I think ?

I am not an expert in ferrite antennas, just have a gut feeling: shouldn't the rods be moved more to the center, so that they are not sticking outside of the coil? Intuitively, the magnetic material

531 kHz UnID-- Ausralian Assistance Needed (Again)

This is another mystery recording from last month's Poipu, Hawaii DXpedition, featuring Australian English on 531 kHz at 1503 UTC during a sunrise session on November 5th. There is apparently a

Re: New style FSL Part 2

Dean, Are the nulls sharp on the main loop? Like a loop which is edge-wound? I'm imagining all that ferrite stuck through the loop sideways distorting the pattern. Maybe it doesn't effect it that

By mediumwavedx · #29077 ·

Re: New style FSL Part 2

It would be interesting to see how you align the two loops and the directions of the received and the offending station/noise. Even just a quick sketch would be very helpful, as I'm not
