10m Es

In the northern hemisphere we have the sporadic E (Es) season, which offers good QSOs on all modes on bands like 10m, 6m and 4m.  Occasionally, it is also good on 2m, but this is far rarer. Skip is usually 800-1500km.

As a child, I used to see what DXTV came through on Band 1 TV.  I well recall the lunchtime watching Midi-Pyrenees via Es on 819 lines. On a standard 405 line TV we got 2 images side by side with a black band in the middle. There is far less TV on Band 1 these days. I am not sure which countries still use it.

As is often the case, I am on 10m FT8 RX with the tiny indoor loop antenna. So far today, 5 stations spotted. 

UPDATE 1015z: 16 stations so far spotted today on 10m FT8 RX.  All Es I think. 

UPDATE 1450z:  87 stations spotted so far today on 10m FT8 RX. Furthermost is 5T5PA (3791km) in West Africa. Nothing yet seen from the Americas.

UPDATE 2016z:  116 stations spotted on 10m FT8 RX with the furthermost CE2SV (11716km) in Chile.

Call me sir? - NOT amateur radio

This stately home was a nursing home after WW2. It is where I was born. If you insist, then call me Sir Roger 😉😉.

Cambridge Market - NOT amateur radio

The photo shows Cambridge Market earlier. 

The statue in the foreground is in memory of Snowy, who was a famous local character who raised a lot for charity. We used to see him often.

The church in the background is Great St Mary's, the university church.

Mating? - NOT amateur radio

 

These look like they are holding hands, but I suspect they are mating.

160m antenna

There is a misconception that 160m antennas and grounds have to be big. This antenna fitted in a small attic and results suggest it does very well. 

Most people have high noise levels on the LF and MF bands these days, but I find FT8, with its effective 50Hz bandwidth, is still effective. 

You may be surprised by results. I was.

10m FT8 RX (Tuesday)

At 0718z, I turned on 10m FT8 RX using the tiny indoor loop. So far, 3 spots at 0822z.

UPDATE 1305z: 71 stations spotted so far with the furthermost VO1CH (3737km).

UPDATE 1810z:  96 stations spotted so far today.

10m FT8 RX yesterday

425 stations spotted yesterday on 10m FT8 RX with the indoor loop antenna including both the USA and South America. Lots of EUs by Es of course! 

Optical link changed

 A reminder that if you find any errors or omissions on my new web pages, please let me know so I can address them. Mike pointed out an old link that I have (hopefully!) corrected. I am sure there are others.
