Software
I am a software developer by trade so the easiest way for me to give back to the hobby directly is by writing software. I have three offerings that I have been supporting:
Cab-converter: This is a utility that creates Cabrillo files that can be submitted to radio contest sponsors.
BeaconWatcher: This is a small utility that identifies the NCDXF beacons active at this moment
QSLpro: I wrote this mostly for me, but I am sharing it. This provides a label printing function for MacLoggerDX users that is especially handy for DXpedition QSL managers.
I have other ideas for software packages... I just need more time to get the coding done.
