QuickSilver QS1R Receiver user Photos and Video

Ken N9VV , graciously sent in some of his photos and a video of his SDR Radio setup. He is using the QS1R Receiver that covers 10Khz to 62.5 Mhz. The QS1R is a direct sampling SDR receiver that connects to your PC through a USB 2.0 port. Ken uses an inexpensive mITX Atom 330 PC to act as a server to the QS1R Receivers software. That way he can access it from a remote location in his shack from another PC. Thanks Ken!

WoodBoxRadio Fxpad for PowerSDR

WoodBoxRadio has just recently  released their Fxpad touchscreen software for PowerSDR. This is a program that allows you to use an off the shelf 7 inch usb touchscreen  as a very nice looking external controller for PowerSDR. Fxpad provides you with a gorgeous multi purpose meter as well as buttons for commonly used functions within PowerSDR. The idea behind Fxpad is to allow your main PC screen to display your logging software or PSK31 software, while displaying information from PowerSDR on separate touch screen. This as would provide quick touch screen control over your SDR radio. Fxpad also a has a set of macro buttons to allow you to define your own commands sent to PowerSDR. Fxpad uses CAT commands to send and receive data from PowerSDR. You will have to setup and define a CAT port for PowerSDR using VSPmanager or com0com. If you are already using CAT for PowerSDR to control PTT for another program, you will have to use something like VSPE to split the serial port. Fxpad is primarily designed to be used in conjunction with WoodBoxSoftwares Tmate tuning control in mind. Even though WoodBoxRadio states that the software needs the Tmate controller to function properly, …

There are many applications the iPad can be used for, but did you know that you can use it as a Touch Controller for controlling your radio or other digital software? Therefore, freeing up your main computer screen for displaying data you need to see, while the iPad delivers touch control or remote control capabilities. If you don’t already own an iPad, this may be a great excuse to get one! You will find several uses for the iPad as a Touch Controller for your Amateur Radio software or even a Remote Monitor for your radio. For example the Touch Controller setup can come in very handy when you want to leave your PSK31 decoding software on your main computer screen while controlling your rig with the touch screen on the iPad. This could also come in handy during a contest where you need fast and easy control of your rig. It is also possible to use the iPad as a Remote Monitor for your radio. The Remote Monitor would allow you to pick up the iPad and go to another location in your home and control and monitor your radio, or even …
