Radio and rails...

After ages I finally made a rain cover for the POTY and led cables into the garage. Big delay there because the garage was a tip. It still is a tip, but the mess has been rearranged so I have access to the air brick where the cables come in! It's nice that when they built the house in the 1930's they put an air brick right there knowing it would be needed for a satellite dish... The rain cover is made from a sheet of plastic that came out of a smashed LCD monitor. I bent it round a bit of 110mm drain pipe using a hot air gun. it didn't quite come out as intended but it's near enough. The front is from the same piece of plastic and is epoxy glued on - yes there is a gap where the glue was less gluey, I'll fix that later. Nylon threaded bar and nuts hold it in place. And it rained an hour after I made it so it does actually work. After all the messing about everything still works. There is a nice box on order to take the gubbins - ok, the Pluto, bias tee, Leo…

I finally mounted the dish. It's been cluttering up the workshop for months now. My original plan was to mount it on a pole by the workshop which would have needed a concrete base and regular trimming of the apple tree and hedge. So, it's mounted on the garage wall with a TK bracket. Aligning it wasn't too bad except I managed first to find the Astra satellite at 19.2 degrees thinking it was the one at 28.2. After I found the second one it was not too difficult to find a satellite carrying Qatar TV using the GTMedia V8. With bolts tightened a bit and after rigging all the gubbins up I found the beacon via an SDRPlay SDR and SDRUno but the levels were well down. The Pluto and SDR Console did a far better job so there will be some setting I overlooked. I copied a couple of QSOs but working outside on a Sunday with the whole estate doing gardening made it rather hard, even with headphones! Anyway, the Pluto is the one that will be used so good to see the whole RX chain working. I have some decent WF100 cable for the LNB feed…

Well I finally got some WF100 cable (CT100 replacement) to get a feed from the now unused Astra dish to the shack. My remaining CT125 is about 10 feet long and would get me nowhere. So I can finally test the Minitiouner on air and it works. No luck with trying to receive GB3YT though, it should be close enough and I have a small 23cm Yagi but our neighbours house is in the way. I will have to go mobile one day and see if it works, which is going to be hard given the rather old Windows laptop has a battery that lasts about 5 minutes and the XYLs laptop is locked down to a work image so no installing Minitioune. Anyway, for now at least it all works. It could us a switch maybe to switch the 12V feed to the antenna socket on and off. Yes it is indeed in a box. This must be the second project I ever built that ended up in an actual decent box looking finished.

Not the most startling of new toys but I've never had a PCB holder. All my construction until recently has been on Veroboard or just lash-ups of wires, until the QRP Labs board. That made me realise there was a gap on the bench. So, this has joined my armoury. The board is a random "let's fiddle with SMD" kit that comes with numerous bits and bobs. I've never had a go at SMD and yet I have two projects waiting to be built which are just that, so this board will hopefully get me up to speed. I figured it best to practice on something that doesn't matter first. I have a headband magnifier, various fine tweezers and tiny soldering iron bits, so should be good to go. Let's see how much of a mess I can make.

I finally got round to starting to build the QRP Labs CW txvr kit which I've had since the 2018 Hamfest. Well, no sense in rushing things. I mentioned before the quality of the kit and the really excellent documentation PDF. I think I'm up to page 25. The documentation is all step by step and easy to follow, with a drawing on each step showing what goes where. The one I got is for 40m - the kit comes with a low pass filter and components specific to the band you request. Of course I do still need to learn Morse! That's still on my list of things to do which includes finish the QO100 project which now has two more kits of parts to build, and read up on the full licence for when, hopefully they release the online exam. Here is a shot of the wound components which, although time consuming was actually quite fun. And finally the completed board with the LCD in place. I went through the alignment process which all went according to plan using the built-in menus. The first pic is of the board powered and aligned and the second a bit of…
