Hello, I am using two USRPs N210 with CBX daughterboards connected to different machines and I have GNU Radio version 3.7 and uhd version 3.11. I installed the IEEE 802.11 a/g/p module for GNU Radio. I ran the wifi_rx and wifi_tx on different machines and the data I send gets printed on the conso

Andy - Thank you so much, this was extremely helpful. I switched to your RF chain and I think it helped a bit. As you can probably guess, I am more of a programmer than an RF expert. It does look like Max has a branch of OP25 which has a deemphasis filter that has been tuned for P25. https://git.o

This. There's a fine line between "stuff that you'd want to adapt from an example" and "stuff that when you write its specification down already looks very much like a program". If you're in the latter case, well, write a program (in that case, a GNU Radio block). As Marcus said, there's a lot of
