* AM Radio Noise Interference May Be Lowered?
Over the past decades, electrical noise on the AM Band has made DXing and even AM reception more difficult. The FCC may enforce their rules to lower noise. They may even add more practical laws to help the AM Band. Here is a Radio World article.

* IRCA Mexican Log, 17th Edition (Winter 2012)
The IRCA MEXICAN LOG lists all AM stations in Mexico by frequency, including call letters, state, city, day/night power, slogans, schedule in UTC/GMT, formats, networks and notes. The call letter index gives call, frequency, city and state. The city index (listed by state, then city) includes frequency, call and day/night power. The transmitter site index (listed by state, then city) tabulates the latitude and longitude of transmitter sites. This is an indispensable reference for anyone who hears Mexican radio stations. Size is 8 1/2" x 11".
Prices: IRCA/NRC members $9.50 (US/Canada/sea mail), $11.50 (Mexico), $12.50 (rest of the world). Non-IRCA/NRC members add $2.00. To order from the IRCA Bookstore, send the correct amount to:

* 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.

* 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.
17 August 2010

* 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.
04 October 2009

* 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.
24 October 2008

* 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.

* Grundig G6 portable review
A very comprehensive review of the Grundig G6 Aviator portable receiver is here.
24 August 2008

* Receiver reviews added
Three receiver reviews from Brian Beezley, K6STI have been added. They are the Sangean HDT-1, Sangean HDT-1X and the Sony XDR-F1HD. They are in the Receivers section.

* Antenna Overview
An overview of the various antennas used for AM DXing is here. If you have additions, corrections or comments, send them along.

* 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.
