Station Entry Categories
General Station Rules
Entrants in “High Power” categories transmit with more than 100W RF, but no more than the power allowed by their license or 1500W RF, whichever is lower.
Maximum output power for entrants in “Low Power” categories must not exceed 100W RF.
All transmitters and receivers of a station must be within a single 500-meter diameter circle. Antennas must be physically connected by RF transmission lines to the transmitters and receivers.
The use of DX-Cluster, Skimmer or Skimmer-like technology (such as Reverse Beacon Network, RBN) is allowed. Spotting information obtained from any source outside the station boundary via a closed or dedicated communication link (such as Web-SDR, Remote Control) may NOT be used. Self-spotting and/or requesting stations to announce one’s own call through a spotting technology is NOT allowed.
Bulgarian stations are listed and ranked separately from foreign entrants.
Only one person performs all operating, logging and spotting functions as well as equipment and antenna adjustments without any external assistance.

Despite the category, only one signal can be transmitted at any given time!
