Amateur Radio Callsign utility

Screen shot 2015-05-02 at 11.36.46 AMWhen creating reports involving amateur radio callsigns, it is useful to be able to sort them according to region, prefix and postfix, as this is the way we are accustomed to thinking about them. In addition, padding them so that call regions align and other types of worthy formatting are applied is something I have found to be very handy.

For this purpose, I developed aa_calllib.py, a Python import library. You are welcome to use it.

SdrDx –OS X and Windows SDR Software

I’ve been working on developing OSX/Mac and Windows versions of SdrDx. At this time, SdrDx for OS X and Windows supports RFSPACE, FunCube Pro, Andrus MK1.5, AFEDRI, FunCube Pro Plus, Peaberry, RTL sticks (RTL supported under OS X only, via this OS X RTL server) and Softrock SDR receivers.

SdrDx 2.17a

In addition, SdrDx can be made to support any SDR with a sound card interface, including I/Q input via your native or auxiliary sound card, with a little scripting work; the Peaberry and Softrock support demonstrate this mechanism using Python.

SdrDx (running on the Mac) is shown to the right. SdrDx is a closed-source, free application.

SdrDx, in combination with your SDR, is an extremely powerful receiver. Reception, recording, playback, analysis, processing — it’s all there, and it’s all been made as easy to use as possible. Extensive documentation covers every aspect of operating the software, as well as providing numerous examples and images to help you along. If you’re an expert radio user, you’re sure to settle right in. If you’re still learning, you can look forward to software that lets your capabilities grow with your knowledge.
