     Interesting observation! I didn't think that the QRM around your channel could be a harmonic from the MW band.
 I will be checking now, because I have a satisfactory reception !,6 - 1,7 MHz, of Greek, Serbian and of course Dutch stations.
  Almost every day, in the 48m band, I observe the second harmonic of Russian stations (from the Crimea area) operating in the 100m band.

Very interesting to watch but shows a very dirty transmitter without any filters at the output.
