Minitioune progress

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.

Another new toy

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.

QRP Labs CW transceiver

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 CW decode but this is on an 11m wire dipole with no ATU. It is possible to mount this in a case and there is a wiring diagram included showing what goes where etc. once the various components are taken off the board - or, rather, not put on the board in the first place. But I will keep mine skeletal, at least for now.
