Function
50Ω RF input from the antenna
RF Ground is internally connected to the module screen and pin 4 (0V).
These pins should be directly connected to the RF return path - e.g. coax
braid, main PCB ground plane etc.
Received Signal Strength Indicator with >60dB range.
DC level between 0.5V and 2V
Ground
2.9 – 15V DC power supply (4.1 – 15V for 50 and 100mW version)
500mV_pk-pk audio. DC coupled, approx 0.8V bias
Received Data output from the internal data slicer. The data is squared
version of the Audio signal on pin 6 and is true data, i.e. as fed to the
transmitter. Output is "open-collector" format with internal 10kΩpull-up to
Vcc (pin 5). Suitable for bi-phase codes
Notes:

Pinout is as NRX1, NRX2 and RX2A receivers
Unlike other NRX family radios, the sense of AF, relative to transmitter input, is NOT inverted
27.095MHz is the default channel.
