[Johnson] Ranger 1 Question/Problem

[Sherrill Watkins]

I think it be better to use a 7-1/2 or 10 watt resistor and space it off of
the circuit board about 1/2" and leave it inside the VFO compartment. I don't
like the idea of mounting it outside the vfo compartment. If concerns are
that critical about it burning up, then protect the circuit with a fuse in
series with the resistor. - Sherrill W. k4own.

Hi Scott:
Actually, I don't think the issue is really frequency
drift as opposed to the catastrophic results of
leaving that 18k resistor in the vfo compartment. Ask
W3BYM (Tom Marcello) (?). He had this problem and
hence a large restorative undertaking that could have
been prevented with the resistor changed and outside
the box.
