The obituary is here.
He will be missed...

* 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.

* DX info wanted
With the next AM DXing season approaching rapidly, 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. We are looking for pretty much anything. DX Log reports, technical information, or equipment reviews. We do not expect that things sent here would be copyrighted and blocked from other sites. That goes against the grain of what a hobby is all about.

* 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
* IRCA Publications
Here is a list of publications shown in the IRCA mailing list. Very good work, and can be quite useful. Link is here.
27 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.

* 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.

* Brazilian station list
There's a list of Brazilian radio stations here. It is very nicely done and it can be shown in many languages.

* Grundig G6 portable review
A very comprehensive review of the Grundig G6 Aviator portable receiver is here.
24 August 2008
* Ultralight Receiver Awards
For those who use smaller pocket radios to DX, there is an Awards program from a group of users. The notice is here.
It's not associated with this site, but we're happy to post it.
16 July 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.
05 July 2008
* Antenna Overview
An overview of the various antennas used for AM DXing is here. If you have additions, corrections or comments, send them along.
04 July 2008
* WestList back
I was able to get the automated update routine for the WestList to work again, so it's back.
Current to 01 July 2008. This is based on the US FCC database, so there may be differences between this and what is actually on-air.
01 July 2008
* 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.
