Hello Ram and the new group, Two years ago on Chuck's old group he started the NC-40a project.? Many of us built the rig and I really like mine. Yes, this group should do some group builds again.? I was getting excited by the 2Nxx everyone was talking about. I googled it and that killed my enthusiasm.? That rig looks like an amazing piece of engineering, wish I could design something like that (but no way!).? 300 parts on a really tight PCB is pretty crazy, would not be a beginners project for sure. You guys who now can not get a PCB for that project should take a look at the NC-40a.? It uses ICs, that's a good thing!? It might not have the receiver specs of the 2Nxx but it is fine for a qrp 2-3watt rig.? Chuck or the group found a great deal on chinese PCBs back then, something like 10 boards or $5 shipped, MANY of the boards must still be out there, many nice guys will probably share some of their extras.? Or the gerbers do exist, hopefully you could get them and order more boards.? I designed my own board over a weekend with free ExpressPCB software and home etched my own board, it was a very rewarding and successful project.? My board used mostly SMD which I find much easier than through hole, I can give the design if anyone wants it. The NC-40a has two good features I don't see in the 2Nxx (I might have missed them): AVC and Sidetone.?? These are really needed I think, and the sidetone is actually your transmitted signal so you know if it sounds correct and has the right offset, etc.? Mine puts out 3watts with a 20cent Chinese final that doesn't even need a heatsink. Think about it, 73, Gary WB6OGD

When the kit launched, support issues took over my life for most of a year.? I'm going to be selfish and not let that happen again.
Finally, all of the documentation for the 2N2/XX is on my web site: so you can get the docs, build any of the 3 bands Manhattan-style, like I did originally, or make your own PCB using DipTrace or KiCAD with the changes you see fit (like DDS tuning and Digital Display) on a PCB sized to your liking.
So, I hate to disappoint all of those clamoring for 2N2/XX PCBs, but for the reasons above, (and a lot of other unspoken reasons) it won't be happening.

Currently gathering parts to build a Norcal 40a. I will make a separate post on this later. It would be nice if a bunch of us get started building projects as a group again.

Re: PCBs for NorCal 2N2/XX Rig
That's too bad, but I understand Jim's reasoning. However, as he said, the info is all there for the taking.?
I wonder which parts he's talking?about not being available anymore? I took a quick look through the schematics and didn't see anything that looked like it was made of unobtanium.?
It does look like a fun project. I have a little experience with Kicad, but I don't think I could pull this off by myself.? 73 Mike M. KU4QO
