*
|
|
* 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
