Nearly gone - NOT amateur radio

Summer has gone and it will soon be time to put in bedding plants to give winter colour. The plants at the front of the house still look OK, but are now past their best. This was the scene yesterday morning.

Sunspots - Sunday October 3rd 2021

 Solar flux is 87 and the SSN 25. A=8 and K=2.

Night Off

472kHz WSPR RX beckoned this evening, but I decided to watch TV instead. Funny how it suddenly seems to have gone dark at night and we have moved into "winter mode".

10FT8R 10m FT8 RX

This weekend, I want to try my simple 10m FT8 RX with 14.037MHz crystals. 

As a benchmark, I want to try first with the original design, then swap crystals but without the toroid near the crystal. I should be able to net the crystal without the toroid.

The simple direct conversion RX uses a Polyakov mixer with injection at half fequency.

See https://sites.google.com/view/g3xbm4/home/hf-mf-and-lf/homebrew/10ft8r-rx .

UPDATE 1400z:  As expected, the even simpler circuit around the crystal works fine with plenty of South American stations immediately spotted. The map shows the stations spotted in just the last 30 minutes on the 10FT8R with the simpler circuit (no toroid) and a 14.037MHz crystal. It works. The revised  circuit is shown on the photo, without the crystal T50 toroid.

UPDATE 1622z: 175 stations spotted this afternoon with the 10FTR on 10m FT8 RX with the simplified circuit. It is impressive.

UPDATE 1746z:  193 stations spotted on 10m FT8 RX with the 10FT8R.  It looks like the propagation is now stopping as darkness falls.

UPDATE 1911z:  QRT. No more stations for some while now.

1971 - NOT amateur radio

The photo shows our wedding day in July 1971. I had hair!

50 years later I am bald and much different.  Where did the years go?

Grandson's crocheting - NOT amateur radio

Our grandson is 12 years old. This is a lampshade he recently did. He is good at art too.

Old cottage - NOT amateur radio

The photo shows one of the cottages in our village. It probably dates from the 1700s.  A few years ago it was extended, not that you would know. 

Yesterday evening on 472kHz WSPR RX

 

Most of yesterday evening, I was on 472kHz WSPR RX using the FT817ND and the earth-electrode "antenna" in the ground. In all, 8 different stations were spotted with the furthermost IZ3QQG (1155km).

DX news

It is a very long time since I chased DX. If I work DX these days it by accident.  To some people, chasing DX is their main focus in the hobby.  The ARRL has a weekly DX bulletin than some may feel useful.

See http://www.arrl.org/w1aw-bulletins-archive/ARLD039/2021 . There is also an archive of past bulletins.

Brighton Lanes - NOT amateur radio

Recently, we spent a few days in Brighton. On one occasion we ate in The Lanes, which is a delightful maze of winding lanes filled with antique shops and places to eat.  

Generally, Brighton was a happy place filled with young people. We enjoyed our short break. As a bonus, we went by a direct train from Cambridge to Brighton and back.
