This has been on before, but it is worth repeating.
HF loops are ideal in some applications. They can work surprisingly well, but are narrow band if efficient. They are ideal with QRP as quite high voltages can otherwise be created. I have used these on several bands. They can easily be made too.

6m FT8 today
This is becoming a habit! Just before breakfast I call CQ on 6m FT8 (2.5W, omnidirectional vertical antenna). Almost without fail, I get spotted by a couple of Gs, often quite distant, even though on TX for at most 3 minutes. The rest of the time I am RX only on 6m FT8. So far today (0912z) just 3 G spots, no Es.
UPDATE 1548z: Just 13 Gs spotted so far today on 6m FT8 RX. No Es evident here.
UPDATE 1612z: It pays to check. An EA1 was spotted but not shown on PSKreporter maps. More recently ON8DM (239km) has been spotted. Currently (only on PSKreporter maps) 15 different stations in 2 countries. With the EA1, that is 16 different stations in 3 countries so far today on 6m FT8.
UPDATE 1816z: Now 27 unique stations in 3 countries so far. Best DX is IT9RZR (2063km). Apart from the IT9 and the EA1 earlier, very little Es on 6m here today. QRT shortly.

May 2m UKAC activity contest results published
Although my voice prevents me being on too long, my score has risen in the AL section results. Using 5W and an omnidirectional antenna and never take contesting too seriously, I am quite pleased. although I shall probably miss June's session.

Stroke? - NOT amateur radio
This has probably been mentioned here before, so I apologise if I am repeating myself.
One thing I am aware of is how fast things seem to be going on the roads. When I am going 50mph it feels at least 60mph. Indeed I feel like I am going 70mph. Then I see a huge queue behind me! I am only too aware that I drive more slowly than I did. It feels embarrassing, but cannot safely drive faster.
OK I am growing older and becoming a grumpy old man. Maybe it is an age thing, but it as if my brain operates at a slower pace. I also find watching subtitles on TV hard work. Usually I give up!
It feels like the recovery from my stroke has stalled.

More on 40MHz in EI
This came in from John EI7GL:
"Hi Roger
You might be interested in the new proposed 8m and 5m bandplans in EI. This was on the IRTS news today...
Spectrum News
Following a spectrum award by ComReg the entire 4m band (69.9 - 70.5 MHz) is now available to Irish licensees.
At the last IRTS Committee Meeting a sub-committee was convened to develop band plans and propagation beacons for additional spectrum included in the spectrum award.
IRTS is now consulting amateur licensees on two band plans covering 40 - 44 MHz and 54 - 69.9 MHz. More details including draft band plans can be downloaded from the IRTS website, www.irts.ie/downloads
Please send any comments as soon as possible to “newspectrum /at/ irts /dot/ ie” to arrive not later than 30th June 2018.
John, EI7GL"
It would be good to get a small secondary amateur band at 40MHz in the UK and more widely. As commercial gear does not cover this, it would be an ideal band for real Es propagation research. How about OFCOM allocating 50-100kHz at 40MHz to radio amateurs at, say, 10W on a strictly non-interference basis? Silly me, this requires thinking. Silly boy.
At our local museum - NOT amateur radio
Our granddaughter earlier today at our local museum playing with a hoola hoop. Years ago, these were all the rage.

Es and thunderstorms
Some say there is a correlation between thunderstorms and sporadic-E, possibly sprites going upwards from thunderclouds. A good source of data on spaceweather is http://spaceweather.com/
