DX TESTS

Brandon Jordan is our new DX Tests co-ordinator, working for both IRCA and NRC. He has established the above PO Box/email for correspondence. He is also available at 901-592-9847 or FAX: 866-240-4221.
Brandon has registered dxtests.net url and will be working on getting a Wordpress blog set up there in preparation for the upcoming season. He is also anticipating former DX Test workers to be assisting him in his efforts. In addition, he is also considering arranging DX tests on SW stations.
DX Tests are âarrangedâ with various AM stations across the US and Canada. A DX Test broadcast would most likely be conducted sometime in the overnight hours, between midnight and 6:00 am typically just after midnight, or just prior to 6 am. These are the best hours for an AM station to skip to distant locations.
ÂÂÂ
DX Test broadcasts used to be popular during the early days of AM radio, and they continue to this day. When done overnight, theyâre perfectly within FCC regulations, as is broadcasting with full authorized power under the "Experimental Hours" rules of 47CFR73.72. In fact, stations have often combined DX Tests with needed maintenance work or proof-of-performance testing, and engineers have often told us that the reception reports they received indicated the quality and strength of their signal, and gave them an opportunity to see how far it travels under varying conditions.
Tests typically consist of tones and easily identifiable music such as marches, polkas or anything else you might classify as eclectic. This kind of material really cuts through the interference and makes a station easily recognizable. Morse code identifications using a 1000 Hz modulated tone are also widely used. Recordings for broadcast during a DX Test can be provided by our committee.
Please join us in welcoming Brandon on-board for the next DX season. We anticipate hearing from him often.
