Note on 73.3 kHz: Until Tuesday 18Apr evening there was nothing
around 73.3. On the 18th there was a carrier between 73.2-73.3
which I reported WITHOUT knowing about its origin...
Starting Thursday on the 27th there was FSK transmission going on
but ALSO the carrier which first appeared on the 18th...
Wonder if anyone else can hear "extra" carriers.
I do have qrm problems on frequencies around 70..74 kHz.
