Still more software defined radio fun on the Mac

Even though the world of software defined radio started out as a Linux-only endeavor, several recent software releases have put the ball fully into the court of OS X users. [hpux735]‘s new Cocoa Radio release provides a (nearly) fully functional software defined radio for anyone with a USB TV tuner and a mac.

Earlier this week, we saw (and tested)  [Elias]‘ port of gqrx and were reasonably impressed. [hpux735]‘s app does the same job and also provides the source so you can compile it yourself.

Previously, [hpux735] ported the osmocom driver for these RTL2832U-based USB TV tuner dongles to the Mac and wrote a small Cocoa driver. The new Cocoa Radio software uses this driver and adds all the features you’d expect from a software radio package; in the title pic for this post, you can see a top 40 radio station near my house and their insipid hatred of dynamic range.

[hpux735] posted a few videos of his development process. You can check those out after the break.

VirtualBox beta runs Mac OS X

A new beta build of VirtualBox, Sun’s Oracle’s free x86 virtualization software, makes it possible to run Mac OS X as a guest operating system…no shenanigans or flaming hoops to jump through, just pop in the $30 retail Snow Leopard upgrade disc and go. This had previously only been possible with some awkward Hackintosh-style maneuvering, or using recent editions of commercial virtualization products.

Install OSX on the HP TouchSmart

[Aaron Nelson] of Hijinks Inc. wrote up how he installed OSX on his HP TouchSmart IQ507. It looks and works like you would expect, save for a few things. The touchscreen works, but the calibration is so far off it’s useless. The most important things, like ethernet and the memory card reader, work fine. [Nelson]‘s biggest frustration is that he has to disable the on board audio every time he logs in, so that the keyboard and mouse will be recognized. He is working on improvements, and would love to hear any suggestions you have.
