Hello All, For those hobbyists like Jerry who have wondered about the DXing performance of a smaller-sized FSL compared to a 7.5" transplanted loopstick, I recorded a couple of demonstration MP3's

Hi Jerry, Your antenna questions are probably of interest to several DXers on the Ultralightdx list, so I hope you'll agree that posting the answers on the list would be helpful to others. <<<

Hi Jerry! I can certainly appreciate your dilemma. I decided several months ago to follow the great work of Gary DeBock, Steve Ratzleff and other FSL experimenters rather than take on an FSL project

This is indeed a dilemma. If I want to build the 7.5 inch Ferrite Antenna, the less sensitive 100/44 wire will need to be used due to width restrictions. If I try to construct a larger (much more

I have seen this sold by one particular ebay-er with claims of "520-1710kHz" MW, and "87-108MHz" FM indicating US compatible usage. These would be the most recent listings of the DR-777, so is it

Paul, I think you are correct about skin effect amd current resistance,especially at RF frequencies below a couple MHz. Somewhere, I'veseen tables published by the Litz manufatureres giving losses

Dear Jerry this struck me also right now I have no good explanation for this more wires with same skin effect do not seem to grab me more technically somehow the Poynting Vector power flow into the

One other major and important consideration: there is a remarkable improvement in S unitage and audible gain if a secondary pick-up coil, when used for direct antenna coupling, is also made of 660/46

Probably due to the skin conductive effect

Wow, the difference Raphael found using two types of Litz wire wound on the same Stormwise Ferrite bar is stunning, even accounting for the vagaries of the Palstar R30A S-Meter (I own one). Can

Dinodirect made very interesting proposal : The anniversary celebration for DinoDirect has started! Let's come and revel together! All products on DinoDirect are involved in this campaign. It will

What? I guess I didn't explain very well. What I meant by "Crystal Set" is to add a diode and a pair of sensitive headphones to a FSA and see what it can pick up compared with a single conventional

Should help out quite a bit in helping hear signals in the noise or separate stations in a congested market (Los Angeles). I used to do similar using tuneable loopstick antenna coils and tuning

Thanks Paul, I'm sure you will be very satisfied with the 660/46 Litz wire from Ming. He is a very honest seller, and his material is top-rate. Thanks for sharing the details of your

Hi folks, I've been following this Ferrite Sleeve Antenna saga with great interest. One test I would like to see is just how effective a FSA is when connected as a crystal set (but with no external

thanks Gary just changed my order with Ming from 330/46 to 660/46 100' best and thanks again for this critical information I am the fellow with the pictures of the yellow pails glued together with

Hello Jerry and All, Steve Ratzlaff discovered that 660/46 Litz wire was the best performer for FSL's, and I agree with him completely. All of my FSL's have been made with 660/46 Litz wire from the

Dear Raphael thank you for this most important piece of information best wishes Paul VE3PVB

Hi Jerry! I have used both 100/44 and 660/46 Litz wire to wrap a 38 turnprimary winding on a 19” 125 mu ferrite bar, terminating in a 365 pfdvariable capacitor for tuning the MW band. In this
