Hello Stefan,
I am monitoring 200 - 600 kHz every night with a PERSEUS SDR.
Propagation from Canada has been very consistent the last weeks.
Most nights, I can copy around ten non directional beacons from NFL.
There is also a distinct dawn enhancement around 02:30 UTC.
The last days it is a bit down, however this morning I had still aural
copy from NDB BX on 220 kHz from Lourdes-de-Blanc-Sablon, Quebec over a
4100 km path.
Also NAVTEX reception from Canada on 490 kHz and 518 kHz has been observed.
Like you, it amazes me that propagation is as good as it is.
I have seen excellent summer propagation before, but that was early July,
after the summer solstice.
The only way to find out if there is propagation or not is to check it
every night.
That is the main reason here for making overnight recordings and
monitoring 518 kHz NAVTEX.
73,
Roelof, pa0rdt
