The CDG2000 TX Exciter 1

The CDG2000 TX Exciter 1

This is one of the simpler boards. It is a transmit exciter using analogue techniques. If you do not want to go digital with either a digital exciter or a 15 KHz DSP generator, this is an easy way to get going.

There are two ways to build this. If, like George, you wanted a plethora of manual controls, use it as it is. If however you want it controlled by the PIC controller, then there is a small add-on board that may be used to interface it to the I2C bus.

Note that the PCB and schematic have been updated as of June 2005
