## Gain Controls ## Gain Controls
**The Gain Controls are critical to the best use of the PortaPack / HackRf.** HackRF provides three different analogue gain controls on RX and two on TX. The three RX gain controls are RF “amp”, 0bB or +14 dB),”IF“ 0 to 40 dB in 8 dB steps), and baseband Vga ( 0 to 62 dB in 2 dB steps).
