Probably: the electrons just flow on the other side of the wire... -- Julian, N4JO.

Neat! Would that be coger in the UK? Michael UK

Here in the USA (conus) 24V AC is typically used for landscape lighting and uses direct bury cable.? The requirements to do that are trivial no electrician required.? Good care (fusing) is easy as

Dave, If you look at the corresponding location of the little dots on the opposite side of the board, I think you will find that it is ground plane there as well. They are to bond the ground plane

Not worried about our sturdy plugs. The main risk comes from heater switches manufactured far far away... Michael UK

We're not afraid, we're prudent: 240v/250V bites a lot harder than 110v. You can guess for yourself how I know ;-) The plugs aren't different sizes: they are fused specifically to protect the

Next up, the Tubes versus Valves discussion -) 73 de Lee KX4TT Even without that G3 call sign, Peter, I’d suspect you were in the UK. —Mike Perry, WA4MP

Even without that G3 call sign, Peter, I’d suspect you were in the UK. Why? Because at the regulatory level the British seem to fear electricity far more that we Americans do. We require inspections

That’s if its a hard wired installation with a ring main in the shed and separate lighting circuits etc If a “temporary” extension lead into a socket in the house I think it avoids all the

Nice job! Vis-a-vis the tiny holes, might they be vias? Vias are used to connect various circuit board layers, including ground planes...

The small holes are vias. They connect the front and back of the board together using the plating on the sides of the holes, allowing a trace to continue on the other side. It's sometimes necessary to

The ex equipment gel cells have a "guaranteed" lifetime of 5 years if you look at the manufacturers spec sheets. Even with little use and just on trickle charge that's about what I see before they go

While building one of the first QCXs recently I use a lot of magnification. While doing that I saw all these little dots in the ground plane (that don’t go through the board) and even some very

Mains cable to the shed?? Yes, good idea, but to be legal it would need to be installed or at least inspected by a qualified electrician.? And even with mains power, you still need a data cable to

Hi Alan, correct, but you can buy a RTL SDR usb adaptor for very little expense. I think mine cost around 20 euros. Paul DJ0CU

Hi Linas, Welcome to the Challenge. Join the Discord Website as mentioned by Luc. You will get Info there about some QCX QRG or post yours and someone will certainly find you CU next time. Martin

Agreed. Just look at what 1960-era Heathkit tube transceivers sell for. I’m looking at several on eBay in the $450 range. Even the “parts only” ones are around $150. But for the collector’s

Why go to all that trouble Run a mains cable down to shed, (if need be in a bit of plastic conduit clipped to fence), then no need for battery and control the QDX via a raspberry pi using VNC and
