The name “WSJT” stands for “Weak Signal Joe Taylor” (Joe Taylor, K1JT, is the inventor of these modes), and as the “Weak Signal” part of that name suggests, it is possible for stations with modest power and antennas to communicate using these modes when traditional modes fail. The answer is that these modes are able to support communications under conditions where traditional modes fail. This raises the question of why anyone would want to use these modes in contests, given the restrictions described in the previous paragraph. Only a few contest exchange types are supported: North American and European VHF contest exchanges, the ARRL RTTY Roundup exchange, and the ARRL Field Day Exchange are the only contest exchanges supported.

The full range of contest exchanges seen in CW, SSB and RTTY contests cannot be supported by WSJT-X and similar programs. The contents of the messages are very limited there are only half a dozen stereotyped message formats, and the contents must fall within narrowly-defined categories. All transmitted messages in a given mode are exactly the same length. They are all synchronized to clock time, to within a tolerance of around 1 second all of the FT8 signals being transmitted at any time are in lock-step. All of these modes share similar characteristics. The best-known of these modes are FT8 and FT4, but there are many more. The second class of digital modes is a family of modes supported by the WSJT-X program and its offshoots.

The digital engine software may also display some kind of tuning aid to help users to tune signals in accurately. This software, in conjunction with a sound card or codec, acts as a modem to translate when transmitting between characters, either stored in message files or input from the keyboard, and the varying frequencies that are actually transmitted, and on receive, between the received signals and the characters displayed on the screen. N1MM+ implements them with the help of either a hardware interface (TNC or TU) or more often, using “digital engine” software. These modes are conceptually quite similar to CW. There is no restriction on when a transmission may begin, other than the usual admonition to avoid having both parties to a QSO transmitting at once. These messages may be of arbitrary lengths and may contain any information that can be written down in letters and numbers. The first class of digital modes comprises “conversational” keyboard-to-keyboard modes in which the two parties to a QSO exchange messages made up of characters (letters, numbers or punctuation characters). There are two broad classes of digital modes supported by N1MM+.
