Contest exchange

There are several types of exchange, depending on the contest types. Some are very straightforward (ie. CQWW), some ridiculous with more different exchange types in a single event. The exchage consists mostly of RST + exchange type (or RS + exchange type on phone modes), however some contests omitting the RST. Anyway, RST should be included by default with posiibility to exclude it.

Serial number - very common is the QSO serial number (exchange is 599001 on CW or 59001 on SSB, respectively). The zeros may be shortened on CW (ie. T or O ... like oh, not zero). Some OPs and some software does not introduce the leading zeros to the serial, so the exchange may sound as 5991 or 591 respectively.

Zone - another very popular is the WAZ or ITU zone number. The number can be derived from the callsign, a good contesting software should put the zone number into exchange without any typing, however there must be always possible to rewrite/reedit this number because the suggested zone number can be pretty inaccurate, mostly at US stations (ie. a W6 from CT etc.).

County or province abbreviation - is used mostly in contest of the "country versus the whole world" contest types (UBA, Russian DX Contest, OK/OM DX Contest etc.). The same category is a contest where the postal code (ie. ZIP) is a part of exchange. Such exchanges are moslty geographicallt defined, unfortunately a table with callsigns and the corresponding exchange is mostly not available and the exchange does also not depend on the prefix etc. The operator must mostly receive and write down the whole exchange.

Another constant number or string - is quite frequently used in club contest where the membership number is known because it is related to the call sign. Almost every club publishes its membership list with (at least) call and the number. Any good contesting software must be able to take this number from a predefined list (table). Any callsign related exchange should be processed in similar way (ie. names etc.).

There are many exchange types but very important is if the exchange can be retrieved from a database and the operator only checks the suggested values with the real exchange or the whole exchange must be written.
