Past installments here have dealt with the topic of Software Defined Radio (SDR) and Surfin' tackles that topic again this week; however, this SDR discussion is completely different because this time it's all about using a Mac to do SDR.

Sebastian Mrozek, DO8SEM, wrote software called DSP Radio and you can download a copy at his DSP Radio Documentation Web page. DO8SEM's software runs on Macs connected to SoftRock hardware; his Web page describes the complete hardware and software setups. DSP Radio is still in beta, so all its features may not be complete, but it is functional enough to allow you to have fun trying SDR on a Mac.

Because there are many different SDR hardware devices in the world, Sebastian developed a software development kit (SDK) that you can also download from his Web page. The SDK is easy to configure to permit you to control your own SDR hardware with DRP Radio.

(Thank you Jan-Henrik Preine, DK1OM, for suggesting Sebastian's Web site.)

MacLoggerDX for Cocoa

Speaking of Macs, I want to alert hams with Macs that a new version (version 5 to be exact) of MacLoggerDX for Cocoa is now available from the codesmiths at Dog Park Software Ltd. I had an opportunity to try out the new version and I like it a lot, so give it a spin and you may be sold on MacLoggerDX, too.

Until next time, keep on surfin'!
