It looks like we have the long awaited other half, another revolutionary hack the driver to make something new mod, this time to get SDR TX.
The hardware is an $8us USB-3.0 to VGA adapter, here is the github for FL2K-SDR (like RTL-SDR).
All that is needed is to do some band pass filtering and up/down converting and amplification to make just about any radio you could imagine, from generating mobile telephony signals to short range GPS spoofing for using real hardware when flight simulator training.
We can also make some radical two way satellite communications designs for people and communities living in austere economic circumstances.
All it takes to start is a USB to VGA adapter based on the Fresco Logic FL2000 chip, they are all over those auction and Asian market websites with free shipping.
I hope we can figure out a way to prototype some cool hardware and get some isolated communities talking up and back down to Outernet earth stations even if it is limited to a few KB/month per account.
