So far, this has been a disappointing Es season. Things hopefully will change, but 8m has been very disappointing so far. By now, I was hopi...

Judging by the results on 10m WSPR, the Es season has arrived. I must give 8m another go and 4m. As the season gets underway we can expect w...

Es tends to be very specific. Sometimes Es is there strongly in one place, but absent just a few miles away. Today may be such a day. As y...

We are now seeing days with little or no Es (sporadic E) propagation on 10m and 6m. The "season" is all but over. As years go, thi...

Time and again I have been struck by just how un sporadic Es is. OK, good days are random but there seems to be a pattern that more northerl...

We are now on the verge of the summer Es season in Europe and the USA, so 50MHz should be good out to about 2000km. Occasionally much furthe...

Well, 10m is full of surprises! As late as 2318z  (after our local midnight) I was still spotting K3NAL on 10m WSPR. He was using just 5W ...

After breakfast I checked 6m beacons this morning at around 0730z and was surprised to hear IW3FZQ/B and YU1EO/B coming through marginally. ...

It is getting later in the sporadic E season but there are still plenty of openings to be enjoyed. As I have yet to erect any antennas for t...

Sporadic-E (Es) is an exciting propagation mechanism that allows contacts on the HF and VHF bands out to around 2000km regularly (with multi...

We are now approaching the summer sporadic-E season in the northern hemisphere with excellent 10m, 6m and 4m (plus 2m on a few occasions) pr...

What I think is multi-hop Es propagation on 10m this evening allowed me a QRP contest exchange with NR4M in Virginia USA on CW at a late 22...

As an example of just how strong signals can be on 10m with strong Es conditions take the reports this afternoon from DJ0ABR . With 500mW to...

Well, the 6m sporadic-E season is in full swing again: yesterday loads of Europeans worked with QRP and the vertical and this afternoon bein...

Just took a look on 6m this evening and heard several northern beacons (GB3RMK, GB3LER, OY6BEC) and worked GM8IEM in IO78 square way up on ...

In between other things tonight I've been running WSPR on 6m. Interestingly I seem to be able to consistently copy G8JNJ 184kms away, p...

Only had a brief chance to listen on 10m and 6m today but both bands were busy with Es signals from right across Europe. The season is well ...

Just worked T77C on 6m Es with QRP SSB. I think I've worked this station some years ago but it is one of the less common Europeans and ...

Only had a brief chance to operate today as I was busy in the garden then out at a BBQ in the hot sunshine, but managed to work some 6m QRP ...

Put the 10m QRP WSPR beacon on early today and already there are spots from the G, CT and OY. The sporadic-E season is gathering pace.
