SO2R

- Main article on the sport of amateur radio contesting
SO2R is an acronym for "single operator, two radios" and describes an operating practice employed by some competitors in the sport of amateur radio contesting. SO2R is also a valid amateur radio call sign issued to an active contest station in Poland.
[edit] Description
SO2R is an operating technique used by some competitors in the single-operator categories in contesting. A single station operator uses two radios to listen simultaneously to two different radio frequencies. When the two radios are on different radio bands, an operator can be listening to one radio while the other is transmitting. This can result in increased operating efficiency, as the operator can always be looking for new contacts to increase his or her score. SO2R operation can be a challenge to learn and requires practice to achieve proficiency.
The use of SO2R in HF contests has been controversial in the past. Some feel that the extra expense, complexity, and improved performance that can be achieved from SO2R operation merits the separation of SO2R operations into a distinct competitive entry class from other single operators. While no major contests have yet done this, some will list individual scores in contest results with an SO2R designation where the station reports that SO2R was used.
