A GPS instrument has been added to the list. It uses gpsd or serial NMEA devices. This instrument outputs geographical positions to a PositionTrace. There’s also a new interesting window available : the Map window. It uses map tiles from OpenStreetMap. Layers are also supported. Any module can register a layer to display information over the map.
Applications
Map and GPS Instrument
Audio Scanner
A new application called Audio Scanner has joined the platform recently. A receiver scans through a channel list, the audio is recorded when a channel is occupied. The recordings are stored locally on the disk and can be played while the scanning is in progress. Stations can be associated with each channel so the recordings can be sorted.
Receiver info on Spectrum panel
The Spectrum panel has a property Frequency Click that takes a receiver, spectrum or IQ trace. If that property is set, the receiver frequency and bandwidth are visible on the displayed spectrum (assuming that the receiver frequency is in the spectrum span). The receiver is now frequency-controlled by a click on the spectrum.
Receiver window
The old receiver window has changed. The new one is fully integrated with the trace system and users can now see more than one receiver window on their screen!
Open a receiver window by double-clicking on a receiver trace. Or choose the menu Window->Traces->Receiver and drop a receiver trace on the panel. There is a field for setting the frequency step. Use the mouse wheel on the frequency field to change its value by steps. The demodulation field is hidden if it cannot be set (for example from an icom receiver).
Spectrogram
A new window is available : the Spectrogram. It takes a spectrum or occupancy trace as input and display the data on a time/frequency graph. The level is based on color scale.
