Correct Charuji,
This thread was planned back before 2 days, for benefit of all...
others are also requested to share their building experience.
& availability of components in VU-Land...
VU2SWX U have one extra set of PCB U can gift it to -YC1DCN
-Indonesia. He is very much willing...
we'll discuss abt that, & a drill-vise + 12 V DC motor, late night, today...
