MagicBox2.5

Repo for software and hardware for the MagicBox 2.5 Tx/Rx interface

The K8IQY/KU4QO MagicBox V2.5, is an updated version of the project designed by K8IQY in 2013 and kitted by the 4 State QRP group. In the prior version, the MagicBox could be used to connect a receiver and a transmitter together to operate as a transceiver, with all of the RF switching and Audio Muting handled by the MagicBox. It used a programmed microprocessor to control the functions within the box. The updated version provides all of the RF Switching and Audio Muting functionality of the original, along with addition of an internal, speed adjustable, CW Keyer, power control for transmitters requiring an external power source to be switched, such as a Tuna Tin 2, and a redesign of the PIN diode RF Switching circuitry to handle higher transmitter power levels. This version should handle transmitters below 20 watts, with very low loss.
