I’m looking to put together a demo for a class at work. I have an SDR dongle (RTL-SDR) and since it operates down to the kHz range, I thought I might demonstrate digital modes.
To do this I have GNURadio to do the data capture etc. But I wanted to demodulate and do all the DSP myself. Is there a website that has the pulse shaping coefficients used for PSK31, JT65, and FT8 etc so I can match filter?
I realized while writing this that maybe “Andy’s Ham Shack” Linux software might have this info buried in it but I was hoping someone knew a few websites that were go-tos with this info.
