 *
 * Important components:
 *  - SSR - Solid State Relay: Decouples voltages from battery
 *  - DRO - Dielectric Resonsant Oscillator: Generates modulation signal
 *  - X8: Frequency X8 Multiplicator
 *  - TX: Transmitter/Sender module. Modulates data onto carrier signal
 *  - MPA - Medium Power Amplifier
 *  - HPA - High Power Amplifier
