Royalty, the BBC and their "religious" correspondent - NOT amateur radio

In the last few days the BBC has come under a lot of criticism for the underhand methods used to get the 1995 interview with Princess Diana. My understanding is they forged bank statements to show that people in whom she trusted were spying on her. I may have my facts slightly wrong, so please check the sources yourselves. What is not at doubt is that Diana was deceived to get the interview and some at the BBC apparently knew about this.

In my view the UK royalty will be history within 50 years unless great changes are made. I think the UK queen has done a pretty good job in difficult circumstances. The whole royal family could have done an even better job if it "came of age".

Many royal couples have divorced and some of the royal traditions are plain wrong. I am not a great royalist, but fear the person we could choose as a president if we ever became a republic.  Can you think of anyone?

My vote is for a continued royal family, but with great changes. Hangers on would have to earn a living, and many of the privileges would go. Many look up to the royal family as pillars of society. It is a delicate balance between "otherness" and us. 

Microwaves

This is one area of our hobby I have not done much with. 

I once borrowed a 23cm RX converter and did some tests one night with a homemade 4 el yagi in the room. I also, many years ago, made a 10GHz Gunn oscillator. I had the wrong sort of waveguide and, apart from some very short range tests, did not take it further. These days you can buy some very low cost wideband FM modules that all but eliminate the hard microwave bits. See https://www.amazon.co.uk/Aihasd-Wireless-Microwave-microwave-detector/dp/B00VVDFOHO/ref=sr_1_8?crid=3AXH2GP3143S0&dchild=1&keywords=hb100&qid=1621586561&sprefix=hb100%2Caps%2C180&sr=8-8

One of the things that put me off was the test gear.  I know some have fabricated homebrew measuring gear, but I found optical gear much easier to design, build and test.

The above link allows you to buy the HB100 units from Amazon within days for under £5 each. I am sure you will be able to get them cheaper.

Maybe I should have a go at 10GHz wideband FM?

UPDATE 0852z: A very quick look on eBay found these HB100 units on sale for £1.72 each with quite modest postal charges. See https://www.ebay.co.uk/itm/143788841984?hash=item217a7b9c00:g:VPEAAOSwY31a1FE~. If you buy more than 1 they are even cheaper!

UPDATE 1214z:   I have created a 10GHz webpage. See https://sites.google.com/view/g3xbm4/home/vhfuhfmicrowaves/homebrew/10ghz .

 

Museum - NOT amateur radio

Yesterday our local museum and windmill opened for the first time this year. We were on duty in the kiosk where we take entry money and sell some gifts as shown in the photo. 

We live next door to the windmill and museum.

10FT8R active

At 0800z, I again turned on my 10m FT8 RX using the homebrewed 10FT8R RX and the tiny indoor loop. No spots yet. 

UPDATE 0826z:  So far 1 spot on RX probably by Es - OE3FVU (1189km).

UPDATE 1334z:  25 stations spotted on 10m FT8 RX with the 10FT8R RX and the tiny indoor loop.

UPDATE 1424z:  Still 25 stations spotted.  It would appear this Es opening has stopped although I noticed a Swedish station a few minutes ago.

UPDATE 1950z: 27 stations spotted today on RX. Now QRT.

Sunspots - Friday May 21st 2021

Solar flux is 72 and the SSN 13. A=24 and K=2.

QSY to 160m FT8 QRP

At 1919z I QSYed to 160m FT8 QRP with 2.5W and the earth-electrode "antenna" in the ground. Already there are Germans coming through strongly after just a few minutes. I guess it is now dark over much of the path.

UPDATE 1948z: One spot of my QRP TX by G4UDU (160km) and 9 spots so far on 160m FT8 RX.

10m Lesser Chirpy CW transceiver

It is hard to think I did this 9 years ago! It has been copied across the Atlantic, although as a "compromise" rig I would not use it on the air that much. My main concern is you may miss stations on the channel as the RX is not as good as many. It is all too easy to call on top of a weak QSO.

Compost - NOT amateur radio

As we ran out of compost earlier, we went shopping and bought more as well as other stuff.  

It was not busy.

Frangipani - NOT amateur radio

 

This was seen on our walk at Anglesey Abbey yesterday.

New website feedback

A reminder that the new website pages "went live" a few days ago. It would be good to hear of any omissions, errors or improvements needed. It is early days still, so any things I can do I shall.
