Please see the HF Software Decoders page for links for the software. These programs can, at a minimum, generate waterfalls of digital signals, but may also include other tools useful for analyzing an unknown digital signal. Filter by license to discover only free or Open Source alternatives.

Unfortunately these do not work in GNU octave as they use Matlab built-in java interpreter. I will release GNU octave code soon. It contains all the code to work with the device from Matlab. You will see that the samples are complex! This is because the device uses IQ baseband demodulation and sampling to represent a single side of the spectrum. Here are some Notes and Slides about Quadrature demodulation and sampling.

Because of the automatic gain, in many cases the first couple of seconds of capture will not be useful. You should therefore discard them. An alternative is to use manual gain, but you have to be careful not to overrange when the signal is strong. The Supported gain values 18 : From Matlab it is possible to change these. Example: to start a tcp erver with default parameters of tuning to If you observe no further output, everything is fine.

Although a dongle may stream at 2. You must modify the dongle, more information available here [ link ]. RF Gain Select either automatic gain or a manual gain level.

The data received from the dongle is multiplied by a fixed value to increase the value shown in the spectrum window. These are very cheap SDR receivers, so it's only to be expected that they need calibrating. This option is used to adjust the dongle's frequency synthesiser so the stations are shown on the correct frequency in the console display. Use this option to update the Vendor, Product and Serial values which are stored in the dongle's EEPROM, for example to change the serial number if you have two or more dongles.

If you only have one dongle then this is always started, even if there is a serial number mismatch. If you do have two or more dongles then just must ensure they have different serial numbers, it is quite usual for dongles to be assigned the same serial number at the factory.

This option shifts base-band data to move spike away from the centre of the display. Only supported by the e tuner.. Press Add to add a definition.
