Hi Loyd,

The 7" FSL construction article was published in October of 2011, and there have been numerous improvements in construction techniques and materials since then.

Once your ferrite rods come in from the Ukraine, please contact me directly about these improved FSL construction procedures and materials.

My V115 had a built in recorder but I was not a fan of that radio.

I personally take videos of anything "special" but mostly I don't record my loggings. I do keep written notes of these which I save in MWDxerDB.

Hi Jim,

Since FSL antennas require so many ferrite rods there has always been a demand for inexpensive rods, since the cost of the American-made material is considered too expensive by most DXers. The Russian surplus ferrite rods have usually been the preferred source, which are sold on eBay by sellers in the Ukraine.

Unfortunately the current political tensions are making this source seem uncertain for the future. Even before the current political problems the primary Ukrainian seller raised his prices about 10 times, and cut the quantity of rods that he offers. Multiple Chinese vendors are on eBay, but the quality of their material is uncertain.

If you wish to order from the Ukraine and take your chances, a typical listing is linked below

Hello Zacharias,

I don't have a Tecsun AN-200, but I do have a Terk Advantage loop, which is considered by most DXers to be superior to the AN-200. All of the Baby FSL models here outperform the Terk Advantage when chasing weak DX stations, primarily because of lower noise in the signal-to-noise ratio.

Any DXer with even basic homebrewing skills can build an air core loop which will run circles around the AN-200. Before FSL's were introduced (by the U.K.'s Graham Maynard in 2011) I concentrated on these type of loops, and published a major article on how to build them (from 18 inches side length up to 9.1 foot side length).

Re: Vendor of FSLs?

Hello Gary (and group),

I've been interested in BCB dxing since my youth (in the '70's)

I mostly use a Quantum Loop V2.0+ purchased new (along with his phaser unit) before Gerry went SK, connected to either my 2010 or IC-R8600.

I've been interested in building an FSL, but I've always been blocked when it comes to sourcing the ferrite rods. I've seen very little concrete info on where to obtain except some vague references to eB from some Russian guy.... Are there docs that address where/how to source?

Thanks,
Jim


Re: Why is it?

DX Central - Loyd Van Horn (W4LVH)
 

Echo what Issac said.  

For instance, I am right now working digital modes on 12m.  There are areas I cannot hear right now because propagation doesn’t favor it.  If you were observing you may be able to see me, the station I am calling or both, depending on how the propagation is working for
You.  

This happens even more pronounced as you rise in frequency on the HF band and even into 6m.  There will be many times I can see hams working into China, South Korea, India and other parts of Asia but I can only see the US ham working them.  Propagation path exists for them into Asia but not for me.

Re: Why is it?

The same would be true of other ham transmission modes. It is also true in the area of maritime coastal weather stations and their communications with vessels. Another reason could be greater power and/or more effective antenna for one party to the conversation and the other.
