Perl libraries


We have several small utility libraries written in Perl, mostly focussed on amateur radio applications.

Unless otherwise stated:


Creates an Imager image containing an equirectangular projection of the world map, with optional Maidenhead locator grid and day/night illumination showing the area of enhanced propagation known as the ‘grey line’. Also utility methods for adding dots at locator positions or lat/long coords, and filling grid squares with colour to provide a ‘heat map’ of activity from these squares.


Parses WSJT-X ALL.TXT files, to extract information about stations you have heard.
