Over on YouTube user FMDX HUN (Luc1f3rk0) has uploaded a video showing how useful the SDR# IF Processor and Notch Filter Plugin can be when attempting to DX FM broadcast stations. He shows that it can be used to listen to stations that are almost overlapping by cutting out the unwanted signal.
MPX Output plugin. Allows programs like RDS Spy to work with the audio output from SDR#
Aviation band 8.33 calculator. Automatically converts the current frequency input to an aviation one according to the standard 8.33 kHz channel spacing.
Frequency Lock. Simply locks the frequency change settings in SDR# to prevent accidental changes.
SDR Update Script. Not a plugin, but a script that automatically updates SDR# and installs most of Vasilli’s plugins all at once. To use this script, it must be placed in a subdirectory of the SDR# folder.
Here’s an example video of SDR# running the MPX plugin so that RDS Spy can be used.
On rtl-sdr.ru, the author of several SDR# plugins has uploaded a new one called “IF Recorder”. This plugin allows you to easily record an IQ file of just the intermediate frequency (IF). In SDR#, the IF is the shaded area with the red line which you use to tune with.
This plugin looks to be great for recording example IQ samples of signals because the output file will be significantly smaller and more manageable compared to recording the entire bandwidth. It is also useful for recording IQ files for use in decoding METEOR M2 weather satellite images, as the decoding software requires an IQ file of the LRPT signal. The plugin also has a schedule option which could be used to start and stop recording the METEOR M2 weather satellite signals automatically.
The IF Processor plugin is designed to upgrade the Zoom FFT plugin that comes standard with a fresh install of SDR#. The IF processor plugin comes with a tracking notch filter and an asymmetric filter controls. These features will allow you to easily remove interfering signals that appear on top of your signal of interest.
The Audio Processor plugin allows you to improve the audio output using a controllable graphical audio bandpass filter. This feature can help you to remove any hiss or other undesirable sounds in the output audio.
Recently the commonly used frequency manager plugin for SDR# was updated to version 1.6. The latest version can be downloaded from http://www.sdrsharpplugins.com/. The updates are as follows:
The Frequency Description is now displayed in the upper-right corner of the spectrum analyzer, along with the indicator for multiple database entries for that frequency.
As a result of moving the above information to the spectrum analyzer, the Frequency Manager panel is now 35% smaller.
The Clipboard Monitor now optionally watches the clipboard for frequencies you might have copied from the internet; and if that can be converted to a MHz value it tunes the radio to that frequency.
Function Keys F1-F10 can now be used to tune to a preset frequency.
A new Minimum Signal Strength Line is displayed on the spectrum display. This, along with real-time display of the current signal’s strength when the scanner is running, let you see at a glance how that signal compares to your scanner settings. In addition you can use customize the line with one of 6 line patterns.
Current Signal Strength in dB is displayed in the upper right corner of the spectrum analyzer, just after the Frequency Description.
Timeout and Watchdog timers’ indicators are now displayed in the upper right corner of the spectrum analyzer.
The second plugin is a Digital Code Squelch (DCS) decoder plugin. The plugin will display the DCS codes that are transmitted with the signal and will display all possible compatible codes. DCS is a squelching system similar to CTCSS which allows for radio user sharing by ensuring that radio users are not bothered by communications not intended for them. The DCS Decoder plugin can be downloaded from http://www.rtl-sdr.ru/page/novyj-plagin-dcs-decoder (note page in Russian).
This week on the popular YouTube show Hak5, SDRSharp plugins are discussed once more amongst other topics. This time at around the 17 minute mark, Shannon discusses how to install plugins that do not have automated installers. For an example she shows how to install the Level Meter plugin.
