Polar Mesospheric Winter Echoes reappear.

High above 69 degrees North, PMWE, the winter apparitions of PMSE, have appeared very strongly again.

Anyone interested in high latitude-crossing DX paths on higher HF and lower VHF may see some interesting results, although the ability of PMSE/PMWE to sustain propagation is not proven.  

With that caveat in place, it is nevertheless interesting to note extremely good propagation at 12m over the past couple of days, extending, according to time of day, to coverage of most parts of the globe.  

About 40 minutes before sunrise here today, two-way 24MHz FT8 signals from as far as India were at good levels, with the first signals already present at about 07:15UT.


My received signal reports at 08:05UT

I got a message from a old 11m friend. He lives in Thailand and had some excellent propagation to the Netherlands this morning on CB. Around 7:15 UTC. He's a happy guy at that time since he's not able to talk dutch much in Thailand ;-). 73, Bas
