Sorry, there has been a heavy mistake with my settings on WSPR-X.
The spots for the transmissions of ZS6KTS beacon on 2014-04-14, 17.38,
17.42, 17.52 and 18.00 UTC have not been on 0.001525 MHz (i.e. 1.525 kHz),
but on 5.25025 MHz.
As there are only very few spots for this path at all, I corrected the frequency of the wrong spots in "ALL_WSPR.TXT" file and loaded the spots up again manually. Now only the wrong spots should be deleted.
The correction of my mistake would be appreciated.
Many thanks
