FAQ
What is a DX Test?
A DX test is a special transmission aired by a station for the specific purpose of giving DXers a chance to log their station - something that in many cases may be very difficult or impossible to do under normal circumstances.
DX tests must be aired during what the FCC calls "experimental hours", which is between midnight and 6 am local time at the station - see 47CFR73.72 for more info. Also, most DX tests are scheduled for Monday mornings, because traditionally Monday mornings have been a time for many stations to do routine maintenance on their transmitters. This is good for the station, because many of them will work in a DX test during their normal testing/maintenance. This is good for the DXer, because the band is less congested at this time - thus increasing in many instances the DXers chances of hearing a station.
(Also, 47CFR 73.1520 (a) says a station can run at its licensed power for testing. This is vague and can be read 59 different ways but since the first DX test was run in 1933, the clause has been read to run at the station's maximum power for testing. No one has EVER been fined, given a NOV or a NAL for full power testing at night.).
DX tests programs are as varied as the stations themselves. Most will include Morse code identifications and test tones (two things that really "cut through" the interference better than voice or music), and many will include some special music which will really "stick out" as something out of the ordinary. Examples of this are March music, polkas, TV & movie themes, or Christmas music played at an odd time of the year (such as in October). There are some DX tests which are scheduled on Saturday or Sunday mornings, and, at the request of the stations, on other mornings. But, most are usually scheduled for Monday, Saturday or Sunday mornings.
