Last updated: April Current stable version : Spectrum Lab V2. Main Site: www. html gone for good? html 'backup'. You can download it from this site. Or look into the manual in HTML format , even though the manual included in the archive will be more up-to-date. pdf , but any attempt to create a common index and table of contents for this PDF, using OpenOffice with proper page numbers instead of the hyperlinks has failed miserably - see note in the preface of the PDF document. If you are looking for a short description in German language, look here. The revision history is here. How to use SpecLab with SDR-IQ is described here ; how to use SpecLab with PERSEUS without an annoying virtual audio cable is here , and how to use SpecLab with software-defined radios supporting ExtIO instead of a soundcard , like FiFi-SDR, RTL-SDR, FunCube, SDRplay RSP, etc etc, is described here.

If you need help getting the program running, or have questions about a particular function, look into the Spectrum Lab User's forum at groups. io not at Yahoo anymore. A plugin for Winamp allows to analyse audio streams from the internet see download section. Besides the soundcard and the interfaces supported by the "audio utilities", SpecLab directly supports SDR-IQ and SDR by RFSpace, Inc , and PERSEUS by Microtelecom s. Special waterfall mode for "Radio Direction Finder" with colour-coded azimuth display, based on DF6NM's Wideband Direction Finder with Colour Encoded Spectrogram Display. Now with up to three "notches" adjustable nulls in the synthesized antenna pattern to suppress noise from certain directions. Special "multi-strip" waterfall mode for long term observation of relatively narrow bands Reassigned spectrogram for higher time- and frequency resolution, if certain conditions are fulfilled since Support for image-cancelling direct conversion receivers quadrature input via stereo soundcard Very sharp, FFT-based audio filters which can also be used to shift and invert frequencies, with auto notch, denoiser, etc.

New : Write your own plugin for the FFT filter! With extra hardware like software-defined receivers with high-speed USB interfaces , even higher sampling rates and thus bandwidths are possible. FFT output is buffered in an array with adjustable size for long-term observations with "scroll-back-in-time" while analysis continues. Furthermore, the FFT output can be recorded exported in various formats. Signal generators with selectable waveform, frequency, and optional modulation, plus noise generator Hum filter to remove 50 Hz or 60 Hz plus harmonics, based on Paul Nicholson's algorithm for a multi-stage comb filter with automatic tracking. If you are interested in improving your Natural Radio reception, read Paul's Notes on Domestic VLF Reception. Frequency converter to shift low "IF"-frequencies e. Can be used in a 'soft-VLF-RX'. Other demodulators in DSP-blackbox. Decoder for some time-code transmitters: MSF 60kHz , HBG 75kHz , DCF77 All you need is your longwave receiver and the soundcard.

Modulator and decoder for some 'experimental' digital communication modes like PSK31, BPSK, QPSK, FSK, multi-tone HELL , MSK minimum shift keying since , transmission and reception of letters with a small 'terminal' window. A DLL interface is available to use Spectrum Lab for new digital transmission modes but not in use yet. Fast waterfall with up to waterfall lines per second, making it possible to decode even fast Morse code by eye though it wasn't intended for that, it's fun to watch versatile export function text-file based, for post-processing with Excel etc. Brian, CT1DRP has used the export functions to create spectrograms and signal graphs of the kHz band. Built-in HTTP server so you can write a simple user interface for SpecLab in HTML intended to be used in a LAN, not as a fully-fledged web server.

screenshot of "Components" window from an older version Features which this analyzer does not have but others do Some Applications AMSAT-DL's Earth-Venus-Earth experiment on 2. A short description of the reception technique software can be found here ; more details are on the AMSAT-DL website , and in the AMSAT journal soon. Thanks to DD5ER, DJ1CR, DJ4ZC, DH2VA, DK8CI, DL1YDD, G3RUH, ON6UG, and everyone else who contributed, for being part of the team. The configuration used for the 2. usr ; we used the SDR-IQ for this. usr instead. Beacon Logger for DI2AG July How to use Spectrum Lab to produce field strength plots of DI2AG, an experimental medium wave beacon on kHz in southern Germany.

It realizes some ideas we spoke about at the Ham Radio fair in Friedrichshafen June More info in this document up to now, in german language only : Beschreibung des Einsatzes von Spectrum Lab als Bakenlogger für DI2AG. Update DI2AG has moved to kHz now which is a new amateur radio band in many countries - with the exception of Germany.. Hellschreiber Modes in Spectrum Lab Nov. We used it on the amateur longwave band kHz to make some narrow band transmission. A special property of Markus' Chirped Hell principle is the relatively low crest factor, so it can be used to transmit characters and even small images quite effectively, but unlike sequential multi-tone hell you need a linear transmitter. An image received on a waterfall in "QRSS 3" mode may look like this: LowFER Receiver Using a "Software" IF This article by Lyle Koehler , KØLR, describes a simple "software defined" receiver and some other easier-to-use alternatives to SpecLab too.

Don't miss Lyle's downconversion circuits which he sucessfully uses to the receive US-American LowFER beacons. The last part describes how to log fieldstrengths of LowFER beacons with Spectrum Lab's plot window. G7IZU Radio Reflection Detection Page This nice website by Andy G7IZU monitors Meteor Shower, Aurora Sporadic-E and Solar Flares in real time, mostly using reflections of radio signals in the 50 MHz region. VE2AZX precise frequency measurements Jacques, VE2AZX, describes here how Spectrum Lab can be used for precise frequency measurements in the millihertz region. Don't miss his detailed description - it's actually better than SpecLab's built-in help system ;- Bat Converter If you have a suitable soundcard, you can use SpecLab to make ultrasonic bat calls visible and audible in real-time.

In the menu, select "Quick Settings".. This configuration requires a soundcard with true 96 kHz sampling rate, and a PC with at least 1. The software shows the call in a fast spectrogram with high time resolution, but little frequency resolution , and converts the ultrasound down to audio, notches out constant-frequency "carriers" like your CRT monitor's line sync frequency, which is annoying if it's in the "bat band" , and finally passes the downconverted and filtered signal through an automatic gain control stage. As a test, I used a cheap miniature electret microphone to make this recording of bat sounds 96 kHz, 16 bit, mono.. right-click to save it. If you play it with a normal audio player, you will hardly hear anything. But if you play it into SpecLab menu "File".. I don't know which species it is yet, but they seem to be quite frequent in this part of Germany.

FFT Filter Plugins The FFT-based filter in Spectrum Lab is already very versatile, but it can still be extended with a "filter plugin". These plugins come in the form of a special windows DLL which can be loaded from the filter control panel. To develop your own plugin, download this FFT Filter Plugin package - it contains all required information required to write a filter plugin, and a sample plugin written in the "C" programming language. NOTE: THE DLL INTERFACE IS STILL "SUBJECT TO CHANGE"! Download Spectrum Lab.. To check if you have the latest version of Spectrum Lab, compare the text in the main window's title bar with the revision number and compilation date at the top of this document.

For example, if you have "Spectrum Laboratory V2. If you have SL already installed, you can check if it's up-to-date by selecting Help.. Check for Update in the main menu. The primary download site for Spectrum Lab is here: Primary: www. zip , V2. see revision history. Forwarding of CI-V messages from and to multiple clients e. WSJT-X, RS-BA1 on extra serial ports Timestamped event queue for the Conditional Actions Non-differential encoding for experimental B PSK transmissions New sample formats received over the serial port e. Installer-less ZIP: www. zip This is seriously 'under construction', and is really "only for beta testing" yet.. If the beta-installer doesn't exist, there is no 'beta' at the moment, so use the release version above. Details about the new installer with separate 'Program' and 'Data' folders are here.

io - thanks in advance. As an alternative, check the download section on Ko Versteeg's website. Some of those sites claim they performed an extra 'virus check', but none of those site's owners has ever asked me the author of Spectrum Lab for permission to re-distribute or even re-package the installer, so 'by default' I would not trust any of these sites. The archive includes EXE-file, sample setting files, help system in HTML format and a few other goodies, but not utilities below. Some additional utilities which may be useful: Winamp output plugin to send audio data directly from Winamp to Spectrum Lab not via soundcard FFT filter plugins allow you to insert your own subroutines compiled into a DLL into the signal path, where signals are processed in the frequency domain. The zipped archive also contains the "C" headers with structure definitions for interaction between SL and other applications audiomsg.

You don't need this if you don't intend to use SL as 'Web Receiver' server! DL4YHF's Amateur Radio Software: Audio Spectrum Analyzer "Spectrum Lab" Last updated: April
