This new design by MATCO ELECTRONICS is a project which is half-way between the 1001001 and the 1001002 in terms of construction difficulty. This design utilizes two Motorola RF power transistors in a reliable push-pull amplifier circuit. If you've built our popular 1001001 Mini Mobile Linear and are looking for a little more power in a slightly more challenging project, this should be your next choice. A carrier operated relay circuit is employed in this small 4x4x2 inch (excluding heat sink) mobile linear. It also features a mode switch for either AM or SSB operation as well as convenient chassis mounted coax connectors for easy hook-up. The 15 page construction manual leads you step-by-step through all construction stages assuring you of a working finished project. Even with all new parts the cost should be less than $100.00 even less if you have some parts in the junk box. Note: The use of this device on the 11 meter citizens band is illegal.
