* DX info wanted
With the next AM DXing season here, we'd like to add some information to make this more useful to the DX community. If you have something that you feel would help DXers, drop me a note. DX Log reports, technical information, or equipment reviews.

* High School Football Stations
On various AM lists it's reported that some daytime AM stations that cover high school football keep day power on until the games are over. A potential DX reception.

* MLA Antenna design
Arthur Hernandez has made a new type receive antenna. It's quite a bit smaller than the flag or other loop
type antennas that are common today. There is a descriptive PDF file that can be viewed here.
19 December 2010
* A new SDR Radio
The September 2010 ARRL QST magazine has a review of a new Software Defined Radio. The QS1R is in some ways similar to the others,
yet has some interesting possibilities. It can display a very wide bandwidth and has synchronous AM detection. There are several software choices including WinradHD that can record up to 2MHz of bandwidth. View it here.

* BOG Antenna work
Jim Glover, WB5UDE has done some work with BOG (Beverage On Ground) antennas. A link to the overview is here.
He's also worked on two occasions with portable setups. One here and the second here. It's some interesting work on how these wire antennas can be used.

* Loop Antenna Article
Gary DeBock has been doing some excellent work on building loop antennas. They are various sizes, and can be portable types as well as more permanent varieties. The PDF article is here.
01 September 2009
* Mailing List Back
The AM-DX.COM mailing list is back up and running. Unlike the last one, this hasn't added any costs to the hosting fees. So, it's worthwhile to fire it up again.
It's running now. If you want to join, please drop me a note. It does not have any auto-posts nor any commercial type messages. Nothing but DXing related messages
posted there. And, it's free. No charge, no weird info to fill out.

* Simple Phasing System
I put together a very simple and effective antenna phasing system. It's simple enough that somebody, somewhere must have built this before but I don't remember seeing it.
The article is here.

* Vertical Antenna
Here is a variant on the vertical or whip antenna often used for AM DXing. Link is here.
28 November 2008
* Passive Loop Antenna article
Kevin Schanilec has written an article on the use of passive loop antennas. It includes nulling techniques and how to connect their signal reception to a radio. Some great graphics included. Nice work! The PDF is here.

* National RF LW/MW Ferrite Loop Antenna
National RF has introduced a ferrite loop antenna for the LW and MW bands. A link to the product description is here. It includes a port for an external sense antenna that can make a cardioid pattern, and output gain control. One ferrite loop covers longwave and the other covers mediumwave. Price is about $370US for the unit and one loop, and $90US for the second loop.
21 October 2008
* Palstar R30 Updated
The Palstar R30CC receiver has been updated. A parts supply problem triggered this, but there were some improvements made while redesigning for the new components. A link to the radio is here. One of the better radios for the MW bands.

* Sony SRF-59 audio phasing
Sony has a nice small Walkman radio that works very well for DXing. Kevin Shanilec has found that connecting the audio outputs out of phase and setting
the radios about 90 degrees to each other works for audio phasing. This is a new approach that hasn't been seen before. He has made a .PDF file to
explain the process here.
Kevin has written a PDF of the Sony radio, some history and other useful info here.

* Antenna cable work and notes
I have been doing some work on cables for outdoor antennas, and the results have been a bit surprising. The article is here.
24 August 2007
* Loop antenna work
I'm working on a series of single-turn copper tube loops. So far, results have been very good. Nulling is as good as
a common wire multi-turn loop, but this doesn't need to be tuned. It's broadband from longwave up through the shortwave bands.
A pair of two foot versions have been mounted in the back of my truck at 90 degrees to each other for mobile work. It has been very effective, and picks up much less noise than a whip.
I have an article posted here including construction photos.
A recent modification was the addition of a second pickup on the top of the loop. When run into a phaser, it provides a virtual tilt and much deeper nulls.
The loop was inspired by a version used for VLF weather noise reception on the Stormwise site.
