6m E layer super DX

The blog of John EI7GL reports on some astounding DX on 50MHz (6m). Although reported as multi-hop Es, I have my doubts. This is like the super DX seen every June between Europe and the Far East. 

My theory is this is E layer propagation but, importantly, not sporadic E. In my view, at least some of these very long paths are the result of some sort of chordal hop E layer propagation. The EU to Far East June 6m openings are at the time when mesospheric clouds are often seen. I wonder if this was the same in the southern hemisphere? Any thoughts?

Winter, late afternoon - NOT amateur radio

 


This delightful photo was taken by our sons a few days ago. It shows the setting sun and one of our granddaughters.

2m FT8 QRP (Monday)

At about 1910z, I QSYed to 2m FT8 using 2.5W and the big-wheel omni antenna. So far this evening just 1 spot of me and nobody yet on RX and no QSOs.

You can almost imagine him thinking, "if only someone invented a microprocessor or an SDR receiver". 

Calendars - NOT amateur radio

Every year about now we make calendars for the next year.  These are examples.

15m FT8 RX

At about 0810z, I turned on the 15m FT8 RX system with the FT817ND and the tiny indoor loop antenna. It is now 0836z and 11 stations spotted so far.

UPDATE 1104z:  181 stations spotted with the furthermost UN7GBX (5566km) in Kazakhstan.

UPDATE 1527z:  229 spots today so far on 15m FT8 RX. 

UPDATE 1603z:  234 stations spotted today so far on 15m FT8 RX.

UPDATE 1855z:  247 stations spotted. QRT soon.

80m FT8 overnight

 With 967 stations spotted overnight on 80m FT8 RX, it was quite rewarding on the earth-electrode "antenna" in the ground. Best DX spotted was NR5R (8276km) near the Mexican border in Texas, usa.

Homemade mince pies and Christmas cake - NOT amateur radio

Every year, my wife makes homemade mince pies and Christmas cake at this time of year. The mince pies don't last long! 

Although I am biased, the mince pies are far better than shop ones. The secret is making the pastry as thin as possible.
