Using rustyHPSDR
When rustyHPSDR is run for the first time it will create the wisdom file for FFTW3. This can take a few minutes depending on the system it is running on. Once created it will simply check the file and start the discovery process. Subsequently running rustyHPSDR will check the wisdom file has been created and go straight into the discovery process.
rustyHPSDR will try to discover any HPSDR compatible devices on all the network interfaces and then display a list of the discovered devices.
Simply select the device you want to use and click on Start
You can enter an IP address in Manual IP and click on **Discover Manual IP" to try to discover a known device that is on a different sub-net that does not see the broadcast discovery packets. If found it will appear in the list of devices.
When first started rustyHPSDR will display 2 receivers.
Clicking on RX2 will turn off/on the second receiver display.
The display can be resized by dragging the edges of the display or by clicking on the Maximize/Minimize icon. You can also press F11 to Maximize/Minimize the window.
You can also use Shift-F11 to Maximize/Minimize the window without the title bar.
The high and low dBm marker lines can be adjusted using the mouse scroll wheel. If the Mouse is moved to the left hand side of the Spectrum window the cursor changes. In the top third you can scroll the mouse up and down to adjust the high value. In the bottom third you can scroll the mouse to adjust the low value. In the middle you can scroll the mouse to move both high and low up or down.
You can use the mouse to click on a frequency in both the spectrum and waterfall windows to change to that frequency, and the whole spectrum and waterfall will move. It CTUN (Click to Tune) is enabled the Spectrum and Waterfall will not move but the frequency cursor will move to that frequency. Note the frequency will be set to a value that is aligned with the Tune Step.
You can use the scroll wheel in both the spectrum and waterfall displays to scroll the frequency up/down by the amount that Tune Step is set to.
By default the audio is sent back to the radio for output. You can configure the audio to be played out to an audio device on the computer by selecting Configure and selecting the Receiver tab. Click on the Enable Local Output Device checkbox and select default for the device.
You can then use pavucontrol to route the output to the required device by clicking on the Playback tab in pavucontrol and the selecting the device for the output labelled PipeWire ALSA [rustyHPSDR].
