I got a QDX in the first round, so didn't go for a second one. I'm working toward building a PSSST-20, myself. There's a groups.io group by the same name if anybody is interested. I also designed and had made some prototyping boards that you all might enjoy:
Details here at my site, including a YT video and a link to download the Gerbers or order some from PCBWay.?
But, I need parts before I get the PSSST-20 built. I also have one of PH2LB's crystal tester kits that I just finished last night and am learning to how use for the sake of building my own crystal filter. Fun stsuff!
