The configuration used for the 2. It realizes some ideas we spoke about at the Ham Radio fair in Friedrichshafen June 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.
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..
If you play it with a normal audio player, you will hardly hear anything. But if you play it into SpecLab menu "File".. It is designed to be lightweight, fast, and visually appealing. Usable for testing all kinds of GPS applications. Qtmm is a simple AFSK decoder that uses the computer's sound card for input. It can be used to decode packet radio, APRS and telemetry from amateur radio satellites. JTSDK is a pre-configured collection of open source cross platform development frameworks, Gnu tools, libraries and custom written scripts designed to ease compiling WSJT applications and documentation from source code.
Log4WinNet Log - logging software. Minos is a VHF contest logging program, together with a collection of programs to assist with station and site operation. View the changelog on the wiki for a list of installed applications. Controlled parameters: 1. Dongle Phone system. Initial scan, Hz. Endpoint scan, Hz. Noise level, dB. Magnitude clock frequency correction, ppm. Both play CW or sounder audio and drive external sounder, loop, or ham rig. Related Searches fldigi.
Thanks for helping keep SourceForge clean. X You seem to have CSS turned off. Briefly describe the problem required :. Repeater control program duplex or simplex operation. Can also be used to automatically announce club events or ARRL bulletins. Makes a great emergency simplex repeater. Based on customer feedback, FLdigi is one of the most popular multi-mode programs available today.
This is due to the wide range of modes that it supports and the fact that it's available for multiple Operating Systems. CAT control tuning, memories, etc. Multiple instances of HRD can be ran at the same time. Click here for setup information.
This new mode is becoming quite popular due to its excellent performance on HF. Transit and receive CW from. Auto Tuning. Many customers say that this is the best CW program ever. This program supports reception of the following modes: AX. Nice utility that allows you to quickly save and restore many different sets of mixer settings. Support for this program has been discontinued, but the developers have posted a new link for downloading here. See our FAQ for more details on this. Real time or deferred spectral analysis and waterfall display for weak signal modes.
Can work with WSJT. Very popular program for weak signal communications. This page may not be copied or duplicated in any form without the express written permission of Tigertronics.
Violations will be promptly pursued by our Legal Department. RadioCom 6 is a software suite featuring encoding and decoding of various digital and analog signals from a radio. It is also capable to control radios CAT and significantly improves sound and audio quality.
RadioCom6 is the successor of the successful RadioCom5. All functions of the predecessor were improved and many new features added. It is able to control several radios and significantly improve sound quality. Two Radios can be connected simultaneously to 1 sound card only. You can run and operate several decoders at the same time. That is why the quality is better than anything compatible. The moment RadioCom starts, some of the foremost changes are in plain view: it is distinctive and eye-catching.
It performs real time activity analysis, signal search and collects spectrum data for post time analysis. Scanning, searching, spectrum analysis and traffic analysis. The one of main fields of SA application is the analysis of unknown or unclear, strange signals. This programm will be very usefull to everyone from professional analysts to amateurs.
The main area of SA application is the analysis of unknown or unclear, strange signals. The program is a Windows soft panel operating as a dual channel oscilloscope and spectrum analyzer.
The useful frequency of operation is 20 to 10, Hz in the time domain and 20 to 20, Hz in the frequency domain. The program uses the computer sound card to capture the audio input. This will provide you with features that go far beyond the possibilities of any stand-alone hardware unit.
WDM drivers support. Special modes of dual-channel FFT spectral analysis: Separate channels spectra, Spectra of digital sum, difference, product of two signals, Spectrum of digital product of original signal and its fundamental, Spectrum of Real and Complex Transfer Function, Cross Spectrum.
