For anyone who is interested in the (tr)uSDX,
there is an ongoing pre-order (3rd batch) at the commercial supplier roWaves:

I look forward in building and using this little rig for my SOTA activations. Thanks to DL2MAN and PE1NNZ.

Hi Christian @DL1GKC.
Just information. There are only 5 slots left in the Group Buy for DL. Then the round is full.

Thank you, Manuel @DM3FAM for letting us know. That was really a quick group buy round. 73 de Chris DL1GKC
Edit 13.02.22: 3rd batch at roWaves is also sold out
I had the chance to chase Jeff @KX6I this afternoon on 20m CW. He was using his freshly built (tr)uSDX. The rig sounded great.
After that I was able to record Jeff having an S2S on 40m SSB with Aaron @KG7AZY.

Great!
