Amateur Radio Projects and Software Defined Radio

DSP based Radio Direction Finding Project

PA3BNX ,Lodewijk Baars sent in an interesting project that he is working on. It involves using Digital Signal Processing techniques applied to Radio Direction Finding. He provides the plans, PCB layouts and software for the project. Looks very interesting! Further information can be found here if your interested in taking a closer look at the project.…

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, …

Using the iPad to Control Your Rig

The iPad is indeed a magical device. 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 …

3D Connexion Devices Revisited

You know we are fond here at Ham Radio Science of the 3D Connexion controllers for controlling PowerSDR and other Amateur Radio software. The first article covered using the 3D Connexion Space Pilot to control the tuning function in PowerSDR. A small hack was discussed that would allow you to map the devices buttons to other functions of PowerSDR. Main tuning is accomplished by manipulating the knob on the 3D Connexion device. However, this only works because the developers of PowerSDR included a plugin that talks to the 3D connection device. As a matter of fact, any program that can use the 3D Connexion device has to have this plugin built in. Unfortunately, this makes the device only usable with very few programs. In the previous article, we could get the 3D Connexion device buttons to trigger keyboard commands in other programs, but the knob was useless in all other Amateur Radio Software but PowerSDR.…

Upgrading the PC inside the Flex 5000 C

This is an article submitted by Ken W9YNI on installing a upgrade PC motherboard inside his FLEX 5000 C

 

First I want to say there was nothing wrong with my Flex 5000 C. It worked just great, and I have never been more pleased with the Radio or with the Team at FlexRadio.

I just wanted to go to Windows 7 64 bit, stay up to date with the current OS and get some more head room for future Software. The computer in the 5000 C is a 2 Core Processor running Windows XP, and just adding more memory did not seem to be the answer. I started looking at Mother Boards and CPU’s and Disk Drives both Hard and Solid State. This sort of gets over whelming with all that is on the market. So I took a short cut and called NEAL CAMPBELL K3NC. Neal had also been working down the same line and after 20 or so Emails and a few Phone calls, I bit the bullet and ordered parts. Neal is a wealth of information and goes over backward to help. I can’t give him enough credit for all he does not just for this …

More Ham Shack Case Alternatives

A lot of you liked the idea of having a custom computer case for dressing up your ham shack. These cases give you PC the appearance of a high end piece of Amateur Radio gear. It is a easy project to do if you are familiar with building your own pc. If you aren’t give it a try, it is fun and quite rewarding. It is actually easier to do than you might think. The Zalman HD-160XT was a heck of a deal, but they can not be had right know for the super close out price they were going for. I suggested some alternatives that were far more expensive. I thought I would suggest some cases that were close to the Zalman HD-160XT in price or less. The best deal right now for a case with a color LCD screen is the SilverStone GD02S-MT. This case has a 4.3 inch color touch screen, aluminum construction, remote, and comes in silver or black. The remote is controlled with the included Imon software and remote. The good news is that the GD02S-MT in silver sells for slightly less than the Zalman HD-160XT on sale. The black model goes for slightly more. …
