Painting the repaired top mast section today, not worth galvanizing the inserted tubular section. I finished welding it up yesterday and it was a bit of a nightmare keeping it all straight and true. So hopefully a magnificent 60 foot erection tomorrow, don't you just love Saturdays 
I am now an official expert on the original tube specification and construction techniques for Strumech / Versatower masts, much good may it do me ... And gobsmacked at today's price of Galvafroid cold galvanizing paint
Had to buy just a small tin, it was that or not eat next week!
I am giving it another week for the ground water table to drop some more, then digging the holes for the satellite dish post and struts, I am getting a bit old for mixing 2 cubic meters by hand so have blagged the loan of my pal's concrete mixer. I have probably enough sand and stone here, so not worth getting ready mixed.

Radio telescopes sound interesting. I haven;t done much Ham radio I got a bit bored of the silence with the odd chat here VHF/UHF. HF to noisy. DMR not much at all, also having nothing to talk about. Sometimes people star conversations with me about things I have no interest in.
I'm into Astronomy. I'm not an Astronomer by any means but I've always been interested in Space related things. I wonder if I can build something to where I can get live images from the Mars rover or something?

Tried running any of the data modes, there's still a bit of activity on RTTY/PSK even though FT8 is the data king these days.
The bands are waking up nicely as we move into cycle 25 and with the Es season coming, there will be plenty of signals on 10m which won't be as noisy as the lower bands.
Yesterday (Friday) was my Saturday. One end of the 20m element on my hex had come off at the centre posts so I dropped the mast, fixed it and got it back up in time for WPX this weekend and spent a couple of hours this morning just tuning around and working some of the more distant stations that were about. No real DX but plenty from both north and south america along with a fair few far east as well. 15m was nicely active and at time of writing this, 20m is still heaving.Painting the repaired top mast section today, not worth galvanizing the inserted tubular section.

I managed to get the main post and the tripod support leg bases concreted in a couple of weeks ago, using just over 2 tonnes of concrete. Easter gave me the chance of getting the dish itself up and very roughly aligned. Now I have to machine the parts for the LNB and transmitter aerial supports and legs. All hardware is stainless, dish is 3.2 meter overall diameter. Much still to do, but the heavy work is now done. Needless to say my wife just loves this new obelisk

That's going to work really well - It's one of the more impressive setups I've seen for QO-100.

Messing about with my slim g antenna off eBay and my Uniden UBC125XLT I got a hit on the ISS. Had about 5 mins of it on and off as it went over the south of France.
Had SSTV before but nice to get voice.

The 101 is highly acclaimed, a very nice set up! Is it the V dipole that's new? What bands does it cover?
I now need to get my cubical quad back up after it was badly damaged in the last high winds. The mast is repaired and back aloft, but I was anxious to get the satellite dish hardware concreted in during the dry spell when the ground water was fairly low.

The dipole is made by Pro-sis-tel in Italy . Covers 10/15/20 and 40m

Radio nerds, is kind of thing possible ?

I would have thought you'd need a more significant amount of power to be able to jam a drone ? (Admittedly I know nothing about jamming drones)

Separatists in Ukraine are touting a janky-looking improvised jamming gun for defending against drones.

Hi all. Messing with a Raspberry Pi 4 4GB and wondering how many SDR dongles I can safely run. Looking at using 4 of these Nooelec NESDR SMArt v4 SDR.

Think it’ll work?

Oddly was going too message you about it. Don’t think it’s pushing it too far?
I was actually thinking about you yesterday. I now work at NPL and one of our labs is an Anechoic Chamber. Yesterday we had an open day and I had a proper nosey around, proper interesting stuff, you'd love it.
Here's a photo (from their site however, weren't allowed to take photos):
(Yes, the white thing is a mobile phone signal antenna).

YouTube/Google for your make model and year I’m sure something on there.
You could tap into cig lighter. I did on my BMW 1 series. I added a relay off it linked to the ignition. This way radio only comes on and off with the car. Saves running out of battery.
Yeah that's not a bad idea. Always makes me cringe with a newish car doing things like this.. haha
