CDARC Zoom talks

As I am unable to drive at night, I have really enjoyed the Cambridge  Radio Club lectures via Zoom. They are trying to arrange "hybrid" meetings with personal contact in Cambridge and Zoom lectures for those that cannot get in. In my view, the Zoom lectures have been excellent.

My personal view is that all lectures should be on Zoom only, with a social gathering somewhere else once a month. This would mean no room hire, reduced annual fees, people could watch or talk from anywhere on the planet and people could watch the Zoom talks with others in their homes if they do not have Zoom. I would expect most people have Zoom.

Imagine if CDARC became a worldwide radio club!

Grass cutting - NOT amateur radio

For the second time this year, I cut the grass, just beating the rain. February was very dry, but March made up for it!! 

4m FT8 (Friday)

 As HF looks to be disturbed, I am again on 4m FT8 with my makeshift antenna. At 1043z, no spots.

UPDATE 1245z:  No spots of me, but G4HGI (244km) spotted on 4m FT8 RX.

UPDATE 1416z: GW8ASA (301km) has again spotted me at similar levels to yesterday.

UPDATE 1421z: Nothing outside of the UK so far on 4m FT8. Rather surprised there are not many more stations on 4m FT8. I expect this will change in the Es season.

Lightning

One of the pleasures of UK winter is the usual absence of thunder and lightning. In the UK they can occur, but they are far more common in the summer. 

Although I know the chances of a direct strike are low, they do occur. I know of 2 friends who had this. One of the more common things is a power surge as storms approach.

What I tend to do is keep a watchful eye on approaching storms. If there is any danger, I disconnect everything: antennas, mains plugs etc.. I have no idea if this is the correct strategy. My view is it is better to be safe than sorry.

CME

It looks like the coming days (especially today) could see quite disturbed solar conditions due to a coronal mass ejection (CME) on the sun. I am not clever enough to know how this will effect HF and low VHF.

Red Kites (birds) - NOT amateur radio

Until these birds were re-introduced in England some years ago, you would only see them normally in Wales. Now they are a quite common sight especially near motorways where they seek out road kill.

Sunspots - Friday March 24th 2023

Solar flux is 151 and the SSN 73. A=60 and K=7. Disturbed!! 

Low cost RF modules

A few moments ago I took a peek at RF modules on eBay. This is just one that will cover many bands. Someone much fitter than me could probably design some useful kit around these.

Signs of spring?

In the UK, clocks go forward an hour on Sunday morning to British Summer Time (BST). Already there are promises of better days to come. Weeping willow trees often have hints of green before most others. This one in Ely a few days ago thinks it is spring!

I like the spring as it is the season of new hope after a long, dark winter. The blossom does not last long, but it beautiful for a while. I prefer the spring to the summer.

Under water - NOT amateur radio
