In Bangladesh, amateur radio enthusiasts, often referred to as “hams,” operate within specific frequency bands allocated for non-commercial purposes. These allocations are established by the Bangladesh Telecommunication Regulatory Commission (BTRC) in accordance with the International Telecommunication Union (ITU) guidelines. The frequency plan is designed to ensure that amateur radio operators can communicate effectively while minimizing interference with other radio services.

Here is a general overview of the amateur radio bands available in Bangladesh:

  1. 160 meters (1.8 – 2.0 MHz): This band is primarily used for longer distance communication, especially during nighttime when atmospheric conditions are more favorable.
  2. 80 meters (3.5 – 3.8 MHz): Suitable for regional communications, this band is popular for both voice and Morse code (CW) operations.
  3. 40 meters (7.0 – 7.2 MHz): Known for its versatility, this band allows for both long-distance and regional communication, making it a favorite among operators.
  4. 20 meters (14.0 – 14.35 MHz): This band is ideal for long-distance communication during the day and is often used for international contacts.
  5. 15 meters (21.0 – 21.45 MHz): Similar to the 20-meter band, it is used for long-distance communication but can be more affected by solar activity.
  6. 10 meters (28.0 – 29.7 MHz): Offers excellent opportunities for distance communication when solar activity is high, and is a popular band for newer operators due to the available bandwidth.
  7. VHF (144 – 148 MHz): This band is typically used for local communication, including emergency services, and is popular for FM voice communication.
  8. UHF (430 – 440 MHz): Used for short-range communication and is often employed for repeater operations to extend the range of VHF communications.

Amateur radio operators in Bangladesh must comply with licensing requirements, which include passing an examination and adhering to operational regulations set by the BTRC. Enthusiasts often participate in various activities such as contests, emergency communication services, and experimentation with radio technology, contributing to the richness of the amateur radio community in the country.
