My QSO Distances

I want to see what distance I have crossed with my QSOs, in what direction and when. All separated by band.

Distance versus azimuth
QSO time versus distance
Shortest and longest distance record per band and mode.

Distance versus azimuth

This diagram shows the distance I've covered versus the azimuth of the contact, separated by band. The map I use is an azimuthal equidistant projection with my QTH in the centre.

QSO time versus distance

This diagram shows my QSOs plotted in QSO time versus distance of the contact. The vertical scale is logarithmic so contacts nearby can be distinguished from far distant contacts.

Shortest and longest distance record per band and mode.

When the minimum and maximum are equal, only one QSO has been made and confirmed on the band/mode combination. The measured distances are between the centres of the grid squares, they can differ a few kilometres with measuring the actual distance between two stations.

The graphs and table on this page are generated by analysing my LoTW logbook. The ARRL’s LoTW does not record separate sub-modes and combines sub-modes as MFSK or DATA. Sub-mode FT-4 is grouped together with other modes like e.g. Olivia and Contesta as MFSK and JS8 is grouped together with other data modes as DATA.
