I just saw that GBZ is much weaker in the moment on my wideband window, also DHO38 but not so JXN and all the 3 Alphas (which are stronger than in the last 13 hours)! The MSKs traces are well suited to differenciate between low QRN and a bad propagation.

Do you mean LF and VLF can be compared in that situation? I remember Scott/VE7TIL has reported that LF was totally down before some weeks but he received the EU MSKs very well anyway. 73, Stefan PS: Will your daughter be QRV on LF in CW some day? Please can i get a sked? :-)
