Can you make stingray without full duplex SDR?

Someone told me that you can use some of old Motorola phones to make stingray they can broadcast and receive at the same time how true is that?

Highly unlikely. Back in the day you could remove some filters from old motorolas and do some nefarious things, like semi-ddos of 2g towers. I imagine these phones are now mostly deaf, although not sure about the backward compatibility of todays infra.

too bad, I don't feel like spending 600$ on full duplex sdr
