1. General

Christos Nikolaou, SV1EIA, has posted his latest fork of the open source PowerSDR program, V2.4.4. This fork can be downloaded in a zip file, which contains:

• a pdf file of installation instructions (upon which this web page is based)
• the modified PowerSDR code (.exe and .dll)
• Fred, PE0FKO's All-In-One USB Driver installation package

This zip file can be downloaded from Christos' site.

The installation process requires a pre-existing installation of Flex Radio System's PowerSDR V2.4.4 (minus all of the associated Flex drivers). The installation of Christos' fork is then performed 'on top' of the V2.4.4 installation. The Flex Radio System's PowerSDR V2.4.4 Installer can be downloaded from this location.

2. Install Flex Radio Systems (FRS) PowerSDR V2.4.4

Download PSDR V2.4.4 from FRS

Click the 'Run' button to begin the installation.

You may receive an advisory that the installation would require a reboot in order for the Flex drivers to be completely installed. Click 'OK' to continue. (The reboot will not, in fact, be required for this process).

You may then receive an advisory concerning the 'FlexControl' (an accessory tuning knob provided as a sop to those for whom a radio cannot possibly be a radio if it does not have at least one knob).
Just click 'OK' to continue.

You may then receive an advisory that all previous versions of PowerSDR (if any running on your system) must be shut down and the radios powered off in order for the installation to proceed. Follow the advisory, as required, and then click 'OK' to continue.

9. Setup PSDR for USB Adaptor

Goto PowerSDR application Setup pages
Setup->General->Hardware Config->USB Adapter the application will briefly show a connection confirmation message box.

10. Perform 1-Time Frequency and S-Meter Calibration

Essential one-time setups are the Frequency and Level Calibrations. Both are required in order to have correct frequency reading and valid S-meter measurements. For the Si570 rigs, Frequency calibration is performed inside the ATTiny firmware with the use of CFGSR utility from here http://pe0fko.nl/CFGSR/

For S-meter calibration you need a simple reference signal generator like the Elecraft XG-2 or the Norcal S9 and you can follow the steps from this topic just for the Level Calibration specific task http://kc.flex-radio.com/KnowledgebaseArticle50271.aspx

11. Operate the Radio

You have at this point a fully working homemade rig with ATTiny firmware by emulating the controls of SDR1000 on the latest PowerSDR available version.

This procedure is for non-commercial use and at user's responsibility, meant only for homemade rigs and home users that want to have experimentation and get acquainted with SDR.

If you have been reading Ham Radio Science, you will notice that a lot of the articles featured here are about taking existing technology and applying them to Amateur Radio. Rather than reinvent the wheel, why not take an existing technology and get a little more mileage out of it. This is something Amateur Radio operators are good at, as well as coming up with completely new technology. Amateur Radio operators are known for their ability to find new ways to use stuff just laying around to benefit their hobby. Nowadays, we have a lot of technology laying around, so why not finding ways of recycling it for Amateur Radio use. Thats just what Tobias, DH1TW did with marrying an off the shelf midi controller with PowerSDR. Utilizing Midi as a control language maybe a little to foreign to Radio Amateurs unless you also happen to be a musician. Midi has been utilized for many years as an interface language between electronic instruments, sound modules, and computers. Midi controllers can come with a wide variety buttons, knobs, and sliders for controlling PC music processing programs. So why not use these as input devices to Amateur Radio software? The biggest reason is that most Amateur Radio programs don’t accept midi input. With midi input mapping, you can take any midi controller hardware and map a given knob on the controller to a function in the Amateur Radio software. For example, you could map a knob to control the tuning in PowerSDR.

This is just what Tobias decided to do. Tobias choose to use the Hercules DJ controllers because of it large dual jog wheels, several pushbuttons , knobs, and sliders. He then wrote a midi plugin that would allow you map the numerous buttons on the Hercules controller to PowerSDR functions. The results is a desktop controller that you can use to tune both PowerSDR vfos, make adjustments to volume and other numerous settings from a convenient desktop controller. The details of the project and downloads can be found on the DH1TW web page. Great work Tobias! We will be taking a closer look at the Hercules DJ controller in a future article.
