Is one band too little and all the bands too much for you? The 4O3A, 9A6KX, NN2W and ES5TV initiative brings an interesting challenge and at the same time a certain flexibility — the SO2B category, that is Single Operator Two Bands. Táto kategória je propagovaná portálom SO2B.org, pričom cieľom je umožniť operátorom súťažiť v rámci dvoch pásiem, namiesto tradičných jedného alebo viacerých.

What does the SO2B category mean?
In the SO2B category, the competitor acts as a single operator (Single Operator), but has the opportunity to work on two selected bands. Choosing these two bands is a strategic decision — it's about considering where the conditions are right, where the activity is strong, and where you can get a good ratio QSO vs násobiče.
Stručne povedané: namiesto tradičnej jednopásmovej súťaže alebo viacpásmovej kategórie sa v SO2B súťažíte len na dvoch pásmach, čo je menej než všetky pásma, ale zrýchľuje to tempo a znižuje logistickú náročnosť. Je teda podstatné vybrať si správne dve pásma.
Why an operator might opt for SO2B
There are several reasons why the SO2B category can be attractive. The first is simplicity — instead of handling multiple bands or a complex setup for multiple bands, it's enough to focus on two. This means less equipment, less antennas or less interconnection between bands. Furthermore, choosing two suitable bands means that if there is no activity on one band at a given moment, you can be effective on the other. In addition, for a less experienced competitor, this can be a great step - you belong to the Single Operator category, but you do not have to fight with a full-fledged multi-band. The maker of these rules calls it "global competition, fair scoring".
Rules and categories within SO2B
On the page SO2B.org sú definované kategórie v rámci SO2B: High Power – Unassisted, High Power – Assisted, Low Power – Unassisted, Low Power – Assisted, QRP – Assisted. This means that even in this relatively new category, there are still differences according to performance, equipment used and whether auxiliary technologies are allowed (e.g. cluster / remote info) - so the fairness of the competition is preserved.
Regarding the participation procedure itself:
-
The contestant will take part in a regular competition such as CQ WW alebo WPX (podľa pravidiel).
-
After the end of the competition, he will submit a separate report with the choice of his two bands via https://SO2B.org
-
The SO2B organizing team will process the results and publish the official ranking. Winners receive plaques, all participants receive digital certificates.
Advantages, challenges and strategy
Among the biggest advantages is that the operator concentrates on only two bands, which means less switching of antennas or equipment, fewer moves between bands and, at the same time, still the possibility of a high number of connections. On the other hand, it is a challenge – choosing the right bands is key. For example, if you choose bands where there is little activity or a lot of interference at the time of the contest, you may be at a disadvantage compared to those who choose better. The website gives examples: S53ZO chose the 40m and 20m bands, while PY2SEX used 10m and 15m.
The operator has to think about the technique (antennas, power), how to maintain good performance in the given bands, how to cover multipliers and the use of DX station activities. When choosing two bands, there can be less antenna complexity, less inter-band interference problems, less need for switches or multiple transceivers - this can be a big advantage. But at the same time, you have to accept that your field of activity is somewhat reduced compared to the multi-band giants.
Significance for the radio amateur community
The SO2B category represents an interesting intermediate step – suitable for club operators or those who want a little more challenge than pure single-band, but don't want or can't deploy full multi-band equipment. It also helps to diversify the competition format, add a new category and motivate radio amateurs to participate. According to SO2B.org, the goal is for SO2B to become an official category in CQ WW and similar international competitions in the future.
Conclusion
Ak patríte medzi rádioamatérov, ktorí hľadajú novú výzvu – kategória SO2B je určite hodná zváženia. Vyžaduje strategický výber pásiem, sústredenú prevádzku a dobrý technický setup, no zároveň poskytuje kompaktnú a efektívnu platformu súťaženia. Vzhľadom na všetky výhody a pri súčasnej jednoduchšej logistike dvoch pásiem môže SO2B byť skvelou voľbou pre leto-jesenné súťaže. Využite príležitosť a možno budete jedným z tých, ktorí túto kategóriu podporia k jej plnému etablovaniu.
73 and many successful connections!
