With overall increased temperatures of radios, you need a way to keep them cool year round. Enter the SMB-201, the smart solution to aid in heat dissipation for radios running hot owing to the higher duty-cycle loads of the digital modes, like WIRES-X and packet operation. When using some of these radios as a desktop/hamshack radio, the SMB-201 is a must-have. Don't worry about power, this cooling solution comes with SAD-11B AC power adapter.
