COHIWizard is an application which allows for playback, recording, analysis and processing of broadband RF signals when using a STEMLAB125-14 by Red Pitaya . Main purpose is archiving AM radio bands like LW, MW, SW, VLF in the context of COHIRADIA but other purposes can be thought of. While recording the data is stored in IQ data files with 32 bit per sample (2 x 16 bits complex) and carries an extended wav-header in the standard format used for most software defined radios (SDR).

Appropriate recordings can be played back on historic Radio receivers with external antenna jack and all transmitters active at the time of the recording can then be tuned through and listened to on the radio. Detailed information for installation, hardware setup and an archive with many recordings from 2006 on can be found on COHIRADIA.

1. download the respective installation package from the COHIRADIA webpage (zip file)
2. unpack the zip file to a local directory of your PC, say cohihome
3. start the exe File COHIWizard_v1.3.x.exe, x being the last sub-version

1. install Python v3.13.0 on your PC; the COHIWIzard may fail with other versions
2. clone the repository from GITHUB to your PC to a folder, say cohihome
3. change to this folder
4. create a virtual environment with python –m venv venv
5. activate the venv by venv/Scripts/activate
6. install the required packages from the requirements.txt (in cohihome) file by typing pip install -r requirements.txt
7. change dir to cohihome/sources
8. run the main script: python COHIWizard.py

COHIWizard.py starts up a GUI with a recorder/player and various utilities for e.g. visualization of the spectra, resampling, annotation (beta version) and editing of wav-headers.

the main branch is currently up to date with branch 1.3.
