Fun to Build!

The CS40 Transceiver Kit is a great project for licensed Radio Amateurs who would like to build their own SSB Transceiver. Apart from 1 medium-sized SMD transistor, the kit uses conventional leaded components on a quality PCB with moderate component density and a classic  uncomplicated circuit design.  Assembly should be no problem if you have with some previous Kit building experience.  With guidance from an instructor, this kit also make a good first project for Novice Operators.

The kit comes complete with black enclosure and all components including the Speaker-Microphone
