BCB Basics - DXing the 'clear-channel' and 'shared channel' giants.

Using your 'communications skills' to listen to the AM broadcast band [BCB] can be a fun experience. The following method will allow you to start gaining an understanding of propagation characteristics and enjoy just listening to signals. Many enjoy DXing the BCB and then add shortwave listening [SWL] experience. Individuals find like minded people and start to form groups and clubs. The internet allows people in a wide geographical area to connect and carry on these specific hobbies. Many people find the 'radio listening hooby' their only interest. A radio ham and his equipment can quickly start a concentrated examination of these approaches to these exciting hobby areas. Typically regional politics, local emergencies and some intensive propaganda campaigns make use of the broadcast band as there primary media outlet which you can directly follow.

The 'local' AM stations play a leading role in reporting much of the news and sports entertainment in a 'local' area. For a DX'er, these stations represent a great source of firsthand news even better than short-wave bands. The abilty to 'hear them' is the key. A good communications receiver and a little knowledge can get you started on this area of interest. Your abilities will depend on what skills and equipment you choose to use.

The hobby can be expanded in listening to some foreign stations (near border stations) as your skill set and interests start to branch out. During the daylight hours, local staions will fill the band, but in the 'dark hours' things start getting interesting for DX'ing {stations further away}. Separating 'local stations' on a tuned frequency can be accomplished with directional systems. Prime DX'ing hours seem (for me) to be between 2:00 AM to 6:00 or 7:00 AM. The sensitivity and selectivity of a good communication reciever allow for great listening. Using special directional antennas and electronic filtering (Phasing and noise cancelling - see MFJ/DX Engineering) with multiple antennas will increase your capabilities. Getting started you should target your listening to the "giants of the AM band" - they usually have 50,000 watt transmitters. There are two types of these giants, the 'clear channel' stations (one major station on these frequencies in the U.S.) and the 'Shared Channel' stations (more than one station with many others being daylight only on a shared frequency ~ leaving a single station on the frequency at night. To assist your search see the table below (list is NOT all inclusive). See the link after the 'Shared Channel Station List' For FCC assignments.

You can use online caluclators for bearing and distance from your specific location to the latitude/longitude values to determine headings and distance. If you have your location, try putting in the Lat/Long from table to this site: Indo Distance Calculator ~ a simple distance calculator site. It gives distance with heading and reverse heading.

Try tuning to frequency during daylight hours. Depending on distance you may or may not hear the station. Try again after dark and you should start to hear longer and longer distances. Be advised results vary greatly with solar sunspot activity.

Use these to check out your phasing and noise cancelling equipment. Also great to use with a K9LAY directional antenna as your 'main' antenna. This will start to give you some good capability tryouts for your equipment. Enjoy your AM band experiences and good luck. You can then gain better daytime reception of many other stations. My experience is that the directional phasing and noise cancelling works okay on the BCB. Let us know your results with a quick email !
