The transmitter site index (listed by state, then city) tabulates the latitude and longitude of transmitter sites. Also, in this edition, there is a spread sheet with links to web sites, live broadcasts and facebook page of many of the Mexican stations. This is an indispensable reference for anyone who hears Mexican radio stations. Size is 8 1/2" x 11".

Re: 7.5” Loopstick LW antenna

Gary DeBock
 

Hello Igvitk,

My current 12" Longwave FSL antenna is a slightly more sensitive version of the 2015 model 12" Longwave FSL, the design photo for which is attached.

The ferrite rods, frame components and size of variable cap are all the same, although the 660/46 Litz wire has been replaced by 1162/46 Litz wire, which provided a sensitivity boost. Because the 1162/46 Litz wire has a larger diameter than 660/46 wire, though, I was not able to fit enough coil turns on the ferrite sleeve in order to get the start frequency down to 153 kHz. This didn't bother me, though, since the start frequency is now around 195 kHz, which is fine for chasing long range South Pacific and Asian NDB's during a DXpedition.

The variable cap has also been replaced with the razor-sharp tuning "384P" type from Oren Elliot Products, which improved the overall performance of all of the FSL antennas used during the recent Rockwork Cliff DXpedition. That type of variable cap is also now the tuner for the "Frequent Flyer" FSL antennas, three of which we plan to use this November in Poipu, Hawaii.

73, Gary DeBock (in Puyallup, WA, USA) 


Re: 7.5” Loopstick LW antenna

igvitk
 

Thanks, Steve and Gary. I will follow your advice and add extra turns to Amidon rod to increase the inductance. Gary, where can I find information about your 12" Longwave FSL? I like LW DXing and would like to make more powerful antenna than 7.5" FSL.

If anybody has any good links for this, please send them to me. I would love to update this and have a good list moving forward.

There's generally a notice about uploads after the conventions, then presumably everyone forgets about it, hi.

Can’t make it to the convention this year—but would llove to see this presentation. Any chance of sharing the materials afterwards? Even better-could someone videotape the presentation and provide a link? 

This technology is really adding a lot to the hobby. Thanks to all who are spearheading the effort.

I have spent some time of late not being as active but instead sorting and arranging my files. As a part of this I have put together a "best of" collection of my ultralight radio photos.

Re: 7.5” Loopstick LW antenna not enough inductance?

<<<     I should add that my coil is wound with 175/46 Litz, perhaps a little smaller diameter than the specified 100/44 Litz. I've found it works even better at LF, in fact I've found all the types of /46 Litz work better at LF than /44 Litz.

Thanks Steve,

This must be why my 12" Longwave FSL wound with 1162/46 Litz wire was able to track down four new South Pacific NDB's at the Rockwork cliff this month (320-AI, 346-TG, 352-RG and 366-PNI) that I never could get with the 660/44 Litz wire :-)

Re: 7.5” Loopstick LW antenna

Gary DeBock
 

Hello Igvitk (and Steve),

<<<  I’m trying to make the 7.5” loopstick LW antenna according to the instructions. I used the Amidon R33-050-750 rod, 100/44 litz wire, made 122 turns of the coil, which is located exactly in the center of the rod and which length is 106,5 mm. However, the output inductance measured by the multimeter is only 1432 uh instead of 1700 uh. The similar result was shown by another multimeter VICY DM4070. I think that is a strong deviation. Can anybody explain how to solve this problem?   >>>

As Steve has explained, the specified 1700 uH is not an essential inductance value, and there are variations in the inductance of ferrite rods and Liz wire, even among the same manufacturer. The important thing is to have enough inductance to make your loopstick provide good sensitivity on your chosen Longwave frequencies, and in order to do this you need a lot more inductance than what SiLabs recommends for Medium Wave (180-450 uH). Your 1432 uH inductance should be fine for most of the Longwave frequencies, unless you wish to concentrate on chasing the LWBC stations from Europe and Africa on the lower edge of the band, in which case you may wish to add a few more coil turns to raise the inductance up a little. For NDB chasing you should already be OK with the 1432 uH.

Originally five test models were made up for the Longwave loopstick design project, and they were all compared on different Longwave frequencies using a Tecsun PL-360 plug-in system. Full details are contained in the article posted at  http://www.mediafire.com/file/845snah2h4ek9z9/7.5inLWLS.doc/file

Curious, I unsoldered my R33 LF coil and measured it--1546 uH at 100 kHz test frequency--so mine isn't close to 1700 uH either, yet mine will tune down to at least 200 kHz with my PL 380 ULR. Here in USA there are no LWBC stations to be heard so I try for NDBs, which only go down as far as 198 kHz (DIW in North Carolina, a powerful NDB).

So I guess your R33 rod has even less permeability than mine, and the 1432 uH is probably correct. If you can rewind it with more turns, that's what I'd suggest doing. It wouldn't matter if turns on the end were under the rod support, that wouldn't affect the rod's pickup.

Re: 7.5” Loopstick LW antenna low inductance problem

Steve Ratzlaff
 

Assuming you're using a real R33 rod, which if you bought it from Amidon, is most likely the case, then it sounds like maybe your rod's permeability is lower than other R33 rods, and that other than rewinding and putting on more turns, you're stuck with this inductance. I realize the rods are very expensive ($20 here in the USA, plus shipping) so you probably wouldn't buy another one just to see if it gives more inductance. Depending on how low you want to tune in LF you may be able to get by with this lower inductance rod and coil. So you may want to just put it on the radio and see how low your particular radio's SiLab's IC tuning will go--maybe you'll get lucky and it will tune low enough.
