[Elecraft] KX1 Alignment and Test - Part I - Power Supply -Batteries OK?

[W3FPR - Don Wilhelm]

Martin,

Batteries ARE a power supply.

Be safe - particularly when doing testing with a battery supply - they can
produce very large currents (even though only for a short time).

I recommend ALWAYS putting a fuse near the battery terminal of any battery -
even small batteries can produce a very large current if accidentally short
circuited, and molten metal can be the result - think: 'If what the object
that contacts the battery wire happens to be the watch or the ring I am
wearing ...' - well you can guess 'the rest of the story'.

73,
Don W3FPR
