Always ensure that you are using legal radio sets. Unauthorized or illegal use of radio sets is strictly prohibited. Before using any radio set, obtain the necessary permissions from the Bangladesh Telecommunication Regulatory Commission (BTRC). Operating without permission can lead to legal consequences. Do not engage in any financial transactions with individuals or entities to import radio sets, obtain No Objection Certificates (NOC), or engage in any related activities without proper authorization. Be cautious of anyone offering to facilitate the importation or registration of radio sets in exchange for money. This could be a scam. Amateur Radio Society Bangladesh (ARSB) will not be responsible for any illegal transactions or activities related to radio sets. It is the individual's responsibility to ensure compliance with all legal requirements.
