Internet Radio Linking Project

Well, so I'm working on the, I decided to do like M17 mode, the digital mode.

So, because I have, I like to build myself hotspots and nodes, so I have IRLP, ASL node, I have MMDVM hotspot, but I wanted to have dedicated to M17 mode, so i created i printed the pcb with all the components now i'm waiting for a raspberry pi because now to buy normal raspberry pi raspberry pi zero 2w takes time or you can buy double or triple price for it if you want right now but anyway i'm wondering what kind of radio shall i use because for that one there is only one commercial radio available And it's in the US, but I'm in Canada and I don't think I can ship it here and with all these tariffs.

But then I've seen there's some other radios which you can build yourself.

And there is another one which you don't have to build, but there is still firmware which is still under development, so you can only transmit for now.
