If you are interested in HF radio and some radio amateur topics, you may find the FT8 log book interesting. FT8 is a digital mode developed by radio amateurs in the US and allows the reception of very weak radio signals. Very weak signals would be signals well below the background noise you hear when tuned to HF / short wave frequencies. Focussing on a mimimal bandwidth of some few Hz, the signal is still stronger than the surrounding noise that a radio would receive normally using a standard bandwidth of 2.4 kHz. In short, with a power of 75 watt, what I use for long distance calls, and a well tuned antenna, I can get around the world. Behind this link is an application written in python which reads the log of the FT8 software (WSJTX) and writes the log records into a database. These log records are displayed on this site mixed with information retrieved from the official QRZ database which contains Ham radio operator information and a map, I download from google maps based on the location coordiantes of the radio amateur.

Besides radio amateur activities I take every opportunity to go away from the city and stay some time in isolation from modern civilisation. Here some pictures from interesting places.
