No, that’s not me on the left, but close. I just realized that last year was my 55th anniversary in my first hobby of medium wave DXing. Read more
NDB DX is an aspect of our radio hobby where you listen for distant non-directional beacons on medium and long waves. Most countries are phasing these out over the next decade. Read more
Is there a best DX QTH? Probably not, but some are better than others. Draw some maps and check it out. Read more
My small changes to phasing creates remarkably different endfire loop array patterns. I can demonstrate these with empirical results and analytical modeling. Read more
Let’s check out SDR medium wave performance with a variety of front end designs which all work differently and well, most of the time. Read more
Local AM broadcasters operate on different channels in the Americas than in the rest of the world. These Medium Wave split channels are a boon for serious DX’ers. Read more
AM broadcast band radio signals travel great distances at night. You can hear medium wave signals from all around your continent. However, you can’t normally hear stations from across the Pacific or Atlantic. That’s not possible unless you use a Beverage antenna (shown above.) Read more
Wireless direction finding loop is a science and art.
During the 48 hours covered by October 24-25 (2015) one of the premier radiosport events brought the ham radio bands to life. Every fall, around thirty thousand hams worldwide take part in two CQ Worldwide contests. The first is for voice operators, the second in November is for Morse code enthusiasts. The process is quite simple: contact other hams worldwide and exchange a signal report and your location. Scoring is based on the number of successful contacts multiplied by the number of different locations (zones and countries) reached.
There are over 100 channels in the AM broadcast band. During the day, you can hear signals on only a few of these channels. At night, you can hear signals on almost all of them. Why?
