Frequency plan for Bulgarian radio amateurs
Amateur Radio Bandplan: Frequency Allocations and Operational Rules
The bandplan is the essential operating and technical reference for every active radio amateur. It governs the allocation of frequency segments by operating mode (CW, SSB, Digital, FM), maximum authorized bandwidth, repeater channels, and propagation beacons.

1. Structure of the Frequency Guide
- HF, VHF, and UHF Band Allocations: Segmented precisely according to IARU Region 1 harmonized bandplans and national CRC regulatory frameworks.
- Repeater Channels and Standards: Section two details channel designations, standard offsets (-600 kHz on 2m; -1.6 MHz / -7.6 MHz on 70cm), and CTCSS tone requirements for Bulgarian VHF/UHF repeaters.
- Unlicensed and Emergency Frequencies: Includes reference channels for license-free low-power civilian bands (PMR446, CB 27 MHz) alongside international amateur Emergency Centres of Activity (GECOA).
2. Contest Operations and Legal Status
During international contests, operating is strictly restricted to designated contest-preferred frequency segments. Because segment boundaries are adjusted periodically, always verify the latest IARU Region 1 contest guidelines prior to major events.
