Hey all,

Would an air-gap tuning capacitor intended for transmitting hook up any
differently from an air-gap tuning capacitor intended for receiving? I
built a project following the schematic for a commercial product, but the
(intended for transmitting) capacitor doesn't like being hooked up with the
stator grounded. Can't figure out how to make it work the way the schematic
is drawn, so I ungrounded the stator and take the input for the amplifier
from there instead of the rotor. And doing this, it works fine. Anyone
have any input? I'm all ears...

Thanks,

Dave

Most air variables are rotor grounded,,,stator floating ...Frame
grounded same as rotor.. HS
