I designed and built a dual band cw rig that there is a photo of here.
The schematic is here. The whole thing fits in a 1020 peli case with LiFePo battery.
I am currently building 2 more of them (20/30m verisons) to fully check the schematic and my notes. I want to make this fully open source and share all the details, but at the moment my notes aren’t good enough. However, if anyone knows what they are doing with SMD soldering of fine pitch ICs and 0603 and has some general RF debugging skills, I have 2 spare PCBs…
