SDR# Frequency Scanner Plugin Updated

The popular frequency scanner plugin for SDR# has recently been updated (in Russian, use Google Translate). The frequency scanner plugin allows you to quickly scan through a definable slice of spectrum, stopping to listen on active signals. The new features are outlined below

1. Added the selection of multiple ranges to scan. Ranges can be different modulation and bandwidth scanning step. To select multiple ranges, use Ctrl .

2. The scanner operates completely independently of native squelch SDR #. To determine the end of the activity, a new parameter Hysteresis – is the level below which the signal is considered inactive. When using the option Use Mute , you can disable the squelch SDR #.

3. In setting the added options – choose the scanning signal with the maximum level and the width of the spectrum used.

4. Parameter Detect moved from the window in the panorama scanner settings.

    I think this doesn’t work with SDR anymore. At least on build 1672 (latest as of today) no scanning actually happens at all.

    The search continues for a scanner-friendly interface in the world of SDR!

    Can this plug in be configured to capture trunked Project 25 Phase II transmissions? And listen to only one talk group?

    It works great. All you need is frequencies entered into SDR#’s native frequency manager. Select “scan memorized without add new”. It reads the data from “frequencies.xml” database and displays it accordingly. It has a controlled timed delay. I recommend 1 second delay at least. Using 0 seconds can make it go wacky. Other than that it does a bang up job doing it’s work on SDR# 1361.

    I have SDR# ver and the scan button stays greyed out after adding the scan frequencies.

    I just got to appreciate the speed and power of this plug when i bought an sdrplay rsp and learned that ihave to use an old version of sdr# because the author also makes the airspy hardware now and dropped support of sdrs in the same market segment. The plugin is not compatible with old versions, so no scanner anymore for sdrplay users :'(

    Excellent maketing move btw, i’m now totally compelled to buy an airspy and i find that company totally cute…..NOT!!!!!!
