[TenTec] Omni D - possible VFO rebuild in my future

[Carlos]

Hi Tom,

It is not a difficult job, it is mostly about dismantling, cleaning,
lubricating, and assembling back. Parts are small, some are fragile,
and go in a certain order.

The day I cannot longer do it I think I'll use WD40 and carefully lube
all moving parts, wiping the excess oil with toilet paper. Doing it in
a hot day will ease things, of course.

Something I have done with my PTOs is to pack more washers in the
back, to ease the pressure that the back spring makes in the whole
assembly. So while I make the radios more prone to minor de-tuning due
to shock and vibration, the tuning knob can be spun around with just
the small finger (I don't plan to rattle those radios in the car and
all have external speakers).

73,
Carlos VK1EA
