IK5ZPV on 24 October 1999
The end of my first QSO with Italy. It was in the middle of the day so mostly groundwave. IZ5ZPV is in the middle of the screen and his very weak CW says K(?) RRR TU SK. The changes of colour show rapid QSB. Most of the contact was even weaker than this! Dot speeds were 3-4 seconds.
Also visible on the Spectrogram plot is the end of a QSO between DJ5AO (bottom left) and PA2NJN (top centre). This second QSO took place within 20Hz of mine, with no mutual QRM.
The signals were received using Spectrogram 5.0.9 in an equivalent bandwidth of 0.3Hz.
