1/8W resistors are available freely, here in Mumbai. Amongst , others , its
available with VISHA Electronics, people in Mumbai should know VISHA at
Lamington Road.

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...
