Simple PSK31 transmission in GNU Radio

[madengr]

Another amateur radio video I put together. I put this tutorial together as I figure out how to do PSK31 in GNU Radio. For now, I generate the varicode data into a file, then transmit that into GNU Radio and a USRP. Next step is to do a dynamic flow where the keystrokes are stuffed into a bitstream. The video explains the Python code to generate the varicode, the modulation blocks in GNU Radio, measurements, and reception.
