The analog output on the receiver module (Received Signal Strength Indicator (RSSI) pin 3) can be connected to an ADC and used as a rough indicator of signal strength whenever the receiver is locked on an RF signal. To be useful, it needs to be read only during signal transmissions. When there is no signal present it will still be a bit high.This is why I had originally asked if you had RF keypads - I guess I was a little vague on what exactly those were. You would be looking at the Receiver Enable field or rE Eliminate that problem and see if any other persist, check related programming in case something got defaulted somehow.EXAMPLE Antenna Range Calculator: INPUTS: Pt = 20 dBm , Gt = 13 dB, Frequency = 2400 MHz, Cable_loss = 3dB, Receiver sensitivity = -80dBm OUTPUTS: Free Space Path Loss = 110 dB, Antenna Coverage Distance = 3147 meters Antenna Range Calculator Equation.
