Description: The NorCal 40B is a compact and efficient 40-meter CW transceiver. No other QRP transceiver offers its combination of extremely low current drain, high performance, reliability, and ease of assembly. These and other features have led many operators to choose the NorCal 40 radios, both for home station and lightweight field use. Originally a project of the Northern California QRP Club, the NorCal 40B and its predecessors, the NorCal 40 and 40A have been field-tested by thousands of QRP enthusiasts world-wide. With the NorCal 40B, the classic design has been further revised, making it easier than ever to build and operate. We've retained an essential ingredient that has made this rig so successful: the flexibility to adapt the ‘40B to your own needs. There’s plenty of extra front- and rear-panel and interior space.
