Just like last year i notice that some of the very far MSK transmitters seem to be bettwer visible in the summer time. Maybe, if the top DX distance on VLF by amateurs will be well above 3500 km, the southern hemisphere becomes interesting. Then, chances may be optimal not during the absolute winther months but maybe in spring or autumn? Still there is a lack of receiving stations there, at least receiving in DFCW-600 or DFCW-2400. I still plan to convince a station in Greenland/OX to become active on VLF but it's not so easy... 73, Stefan/DK7FC
