Re: QCX PC board spots and mini holes

I think those are probably stitching via's / ground plane stitches, I suspect you'll see that there's a ground plane fill on the other side right under them too, and these 'stitch' the two sides together electrically for a more complete ground plane.

Subject: [QRPLabs] QCX PC board spots and mini holes

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 small holes not used for part installation. ?I tried to point to them with red lines. Can anyone tell me what they are and what they are for?



It took me a long time to find time and true interest to dig into these kits even though I bought them maybe 3 years ago. ?I bought three from Hans at Dayton the first year he was selling them. ?I should have begun sooner as they are a fun build and not difficukt at all. I have followed this email account and learned all of the mistakes others have made. ?Also doing T1 FIRST is the way to go. ?Try fitting it in after all her other parts are installed?????

Hi Paul

Nice idea. But then the QCX-mini is by far the smallest part of the whole setup. Can you imagine having a panadapter as a separate?box the size of QCX mini? Like Elecraft's KX3?+ PX3 combo. That would?be really cool!

I know it is a rather ambitious idea, but I could resist it, hi!

Kind regards

This panadaptor looks perfect as an addition to the qcx mini etc.

A description can be seen here:?

And can be purchased on Banggood.com at the moment for around 40 euros.
