Radio calibration not working

I am using pixhawk 2.4.8 and flysky fs-i6 transmitter and Fs-ia6b reciver i have done the compass calibration and Accel calibration but when I am doing radio calibration the green bars are in empty colour.
radio calibration seems to be not detecting signals from my RC even though it has binded successfully and the pins also correct.

Then it’s not seeing the receiver. Receiver bound to the Transmitter? Sbus or iBus protocol configured? Connected from the Sbus out of the receiver to the RCIN pin of the Pixhawk?

Yes I have connected it to ppm and rcin in pixhawk

Make sure you made the correct configuration of your receiver to certify yourself that it is outputting PPM protocol and not RC1 PWM signal. If you have a scope, it could help in this case.

I think I don’t have the encoder will that be the problem

You don’t need an encoder. Configure for PPM protocol in the Transmitter. You have a manual right? Page 21

Maybe you will have to re-bind after setting this.

thanks the transmitter was not set for ppm signal so that’s why it was wasn’t working after setting to ppm signal it works great thanks.
