[Lowfer] How do I....

[John Bruce McCreath]

Here are the results of my testing so far.  I installed SAQrx which provided me a 0 to 22 kHz. spectrum analyser.
The loop is connected to an 8 ohm to 600 ohm transformer (Hammond 119DA) and on to the mic in jack of the 
laptop PC.  No attempt was made to tune the loop with parallel or series capacitance.

The noise floor seems to be in the -100 to -110 dB range.  Between 2 and 7 kHz. there was a "plateau" where
the noise floor was -90 dB.   With the AF signal generator loosely coupled to the loop, I swept it over the range
from 2 to 20 kHz. and noted that the signal came up to -30 dB. across the span of 2 to 7 kHz.

I'm next going to try inputing that data into an on-line L-C-F calculator and see if that gives my a rough idea of
the loop's self capacitance value.  Again, thanks to Bob and Mike for their suggestions.
