What is it?

adiftools is a Python package that provides utilities for ADIF data which is used for the QSO logging file format.

This tool allows you to easily load all QSO data from an ADIF file into a pandas DataFrame. Additionally, it provides functions for graphing the loaded data, as well as utility functions for Grid Locator-related latitude and longitude conversion and distance measurement.

Main Features

• ADIF file parser: Read ADIF file and convert to pandas DataFrame

  • Call signature:

    ADIFParser.read_adi(file_path, enable_timestamp=False)

  • Parameters:
    • file_path: str or path-like or binary file-like
      • A path or a Python file-like object representing the ADIF file to read.
  • Returns:
    • pd.DataFrame
      • The created pandas DataFrame instance includes QSO data from the ADIF file.
  • Other Parameters:
    • enable_timestamp: bool, default: False
      • If True, adds a row named ['timestamp'] to the DataFrame, generated from the ADIF file. The ['timestamp'] row is of type datetime64[ns] and is based on the 'QSO_DATE' and 'TIME_ON' fields.

• Save ADIF data as adi file

  • Saves the loaded ADIF data as an adi file conforming to the ADIF standard. adiftools adds a new header to the beginning of the adi file.
  • Fields with no data are filled with nan.
  • The header will contain information on the following two fields, CREATED_TIMESTAMP, and PROGRAMID.
  • Call signature:

    ADIFParser.to_adi(file_path)

  • Parameter:
    • file_path: str or path-like or binary file-like
      • A path, or a Python file-like object of adi file to save
    • Returns:
      • None

• Save ADIF data as pickle file: Save the DataFrame with the ADIF loaded to a pickle file.

  • Loading an ADIF file into a DataFrame can be quite time consuming.
  • It is especially long if there are many QSOsin the ADIF file, and it is very cumbersome to read the data every time.
  • It is recommended to serialize the ADIF data once loaded and save it in a pickle format, which is expected to be 50 times faster than loading a raw ADIF file.
  • Call signature:

    ADIFParser.to_pickle(file_path)

  • Parameter:
    • file_path: str or path-like or binary file-like
      • A path, or a Python file-like object of pickle file to save
    • Returns:
      • None

• Load Pickle data

  • Provides a way to read ADIF data once it has been loaded by ADIFParser and saved in a pickle file.
  • The read_pickle method does not check whether the QSO data is saved in the read pickle file.
  • Call signature:

    ADIFParser.read_pickle(file_path)

  • Parameter:
    • file_path: str or path-like or binary file-like
      • A path, or a Python file-like object of pickle file to read
    • Returns:
      • pd.DataFrame
        • The created pandas.DataFrame instance includes QSO data from ADIF file

• Save ADIF data as excel file: Save the DataFrame with the ADIF loaded to an excel file.

  • Call signature:

    ADIFParser.to_excel(file_path)

  • Parameter:
    • file_path: str or path-like or binary file-like
      • A path, or a Python file-like object of excel file to save
    • Returns:
      • None

• Generate Callsign file

  • Outputs call sign data without duplicates from data read from an ADIF file as a text file. The text file will contain one callsign per line.
  • If the ADIF file has not been read, i.e., read_adi() has not been performed, it returns the error AdifParserError.
  • Call signature:

    ADIFParser.call_to_txt(file_path)

  • Parameter:
    • file_path: str or path-like or binary file-like
      • A path of output txt file
  • Returns:
    • None

• ADIF data monthly plot: Generate monthly QSO plot

  • Call signature:

    ADIFParser.plot_monthly(file_path)

    Generates a bar plot of monthly QSOs and saves a PNG or JPG file.

  • Parameters:

    • file_path: str or path-like or binary file-like
      • A path or a Python file-like object of the plot's PNG or JPG file.

  • Returns:

    • None
    

• Monthly Band QSO Stacked Bar Plot: Generate stacked bar plot of monthly QSO counts by band

  • Call signature:

    ADIFParser.plot_monthly_band(file_path)

    Generates a stacked bar plot of monthly QSO counts by band and saves a PNG or JPG file. Each band is assigned a unique color for clarity. The color table for each BAND is defined inside the function, and if a BAND is not listed, a unique color is automatically assigned from a colormap to avoid duplication.

  The color codes are inspired by the color scheme used on the website PSKReporter. We would like to acknowledge and thank PSKReporter for their excellent and informative color palette.

  If you wish to customize the color assignment, please edit the color table in the source code of the function monthly_band_qso in adifgraph.py.

  • Parameters:
    • file_path: str or path-like or binary file-like
      • A path or a Python file-like object of the plot's PNG or JPG file.
  • Returns:
    • None

Getting Started

The first step in utilizing adiftools is to load an ADIF file; files that follow the ADIF standard can be loaded. After loading an adif file, you can perform graphing and other operations. Please refer to this page for ADIF standard. The Independent ADIF Site

Example:

import adiftools.adiftools as adiftools

adi = adiftools.ADIFParser()

df_adi = adi.read_adi('sample.adi') # Use your own adi file
print(df)

Dependencies

adiftools requires the following Python packages (recommended versions):

• pandas (>=1.5)
• numpy
• matplotlib (>=3.5)
• GeographicLib API

You can install all dependencies with:
