Softshell, the MacOS RTL-SDR driver
For the uninitiated, a few months ago one of the developers in the V4L (video for linux)/DVB (digital video broadcasting) team, Antti Palosaari, discovered that this cheap video tuner dongle could be used as a software defined radio. Since then, it has developed a HUGE following! The team over at osmocom helped to package the driver into a separate executable. The application seems to work well, and even compiles on the mac. The problem is, though, that you have to install the libusb library for it to work. It’s not hard to do, but you have to install mac ports, then install libusb. What a pain.
Most of the active discussion about rtlsdr appears to be happening at the RTLSDR subreddit.
The idea behind Softshell is to port the osmocom rtl-sdr code into a native Cocoa application that doesn’t need libusb. I’ve published the code to github, but it’s still very early in the development process.
