Over last 8 month I was digging deep into Web Development. The result went yesterday public – DXHeat.com. Instead of building just “another” Web DX Cluster, I tried to build something innovative with new, unique features. Best is to check it out by yourself!
Software Defined Radio
The community of Flex-Radio enthusiasts which select the DJ Console as their main user interface is steadily growing. Community members are sharing pictures]2 to make it even better. After several labeling solutions, a recent discussion on the PowerSDR-UI Yahoogroup ended up in an haptic improvement for the DJ Console’s tuning wheels.
I’m a believer in true knob and button radio interfaces… and I’m not the only one. A small team, formed around Stu, K6TU developed the Contest Knob, which is now today manufactured by FlexRadio Systems under the name FlexControl. In this interview K6TU reveals the ideas behind the Flex-Control and describes in detail the steps from the design to the industrial production.
PowerSDR-UI lifts the FlexRadio experience to a totally new level. Since the first release of PowerSDR-UI an avid community is forming it selve around the project. Literally, I receive now everyday feedback from new users expressing their appreciation. In this post you will find pictures which have been provided from satisfied PowerSDR-UI users. These pictures shall inspire and help you to set up your DJ Console.
The FiFi SDR is a second generation allband HF receiver. Beside it’s QSD it comes with a onboard soundcard and a powerful ARM Cortex M-3 CPU which leaves a lot of room for experiments. I was glad to win Kai-Uwe, DF3DCB one of the FiFi-SDR founders for an interview. Curious? Then download the download the MP3 or subscribe in iTunes to my podcast!
At the end of last year I announced the “proof” that Software Defined Radios also can have buttons and knobs. At that stage the software was still a prototype and not ready for a public release. In the meantime I was working hard to eliminate bugs and implement further improvements. By today I’m happy to announce the release of PowerSDR-UI beta. This is a call for beta testing. Please feel free to download the software and participate in the beta testing phase!
The User Interface of computers suck when it comes to Radio Controlling. In January 2010 I got so annoyed by being forced to control the radio with keyboard and mouse that I finally decided to look for something else. Now, almost one year later I’m happy that I can present you an interesting alternative. The interface costs less than 100 USD, is commercially available and improves the overall SDR experience significantly.
Last weekend I was invited to speak at the Contest Universtity in Friedrichshafen, Germany. This year I tried to visualize a rather abstract topic, the influence of technologies on the art of contesting.
On my ongoing search for SDR appliances, I discovered a couple of weeks ago an SDR (Softrock & Linux) based Beacon Monitoring System. The system is making use of the NCDXF Internation Beacon Project (IBP) which consists of 18 timely synchronized automated transmitters, located around the world. It monitors the signals on the various bands and generates in real-time a graphical chart showing the signal’s strength. The chart is uploaded to a webserver and accessible for everyone through…
This week I had the pleasure to interview Martin, IW3AUT. He’s the developer and founder of the Italian PMSDR Software Defined Radio receiver. In this interview you will get a look inside a successful SDR project. You will read about the design goals, the milestones of the project, the problems which Martin encountered an how he solved them. Enjoy the interview!
