2015-07-26 Mapping amateur radio contacts
In a lot of the amateur radio contacts I have location information is exchanged. This is done in the Maidenhead Locator System which uses letters and digits to pinpoint locations with an increasing precision. I give out my home location as JO22NC. In the contacts I make I also log all those locators and using the Linux version of gcmwin I plot these on great circle maps. The results:
The difference in scale of the maps is because the digimode on HF map is scaled to my furthest contacts (Puerto Rico), the satellite map is scaled towards the theoretical maximum distance I can reach via the SO-50 satellite. The difference in numbers is because it's a lot more work to make satellite contacts!
