Send own message via RF using GNU Radio

Hello,

I’m trying to do the following setup but i don’t know how to do it and i need some guidance.
I’m trying to send a message via RF with GNU Radio via a Hackrf One SDR and capture it with another Hackrf One, Between this process i want to modulate it using various modulation types (FSK, ASK, QPSK, BPSK, etc) on the transmitter side and then i want to demodulate it on the receiver side. I’ve looked up for informations for doing this setup but i failed badly. Any information would be very much appreciated
