Voltage Monitor for an LC circuit

[sophiecentaur]

To simulate a 50 Ohm output resistance with a shunt resistor, can't you just have a current source, in place of an ideal Voltage Source? (It's been a while since I did that stuff.)
Also, I seem to remember that self Capacitance of a coil can be reduced by spacing the turns and having uninsulated wire.
It all depends on the precise requirements but there will be an optimum L value (possibly lower than the existing one). Simulation could save any more winding than necessary.

Also, I seem to remember that self Capacitance of a coil can be reduced by spacing the turns and having uninsulated wire.

This was somewhat of a revelation for me. I've always thought the self capacitance of a single layer air wound coil was a function of winding spacing. Apparently this isn't true. I'd like to track down the actual papers since the physics sounds interesting. My estimate of the (my) coil is the self capacitance is ~6.5pF or so.
