 | L4 at maximum inductance. Not much going on. |  | Decreasing the inductance of L4, signals suddenly snap in at about 66 and 86MHz (86MHz might be a spurious response) |  | Decreasing some more, the freq of the 66MHz peak slowly moves to what looks like 72MHz and "locks" there. Again, the 85MHz peak is suspected of being a spurious response.
|  | Decreasing the inductance still further: signal locks at about 58 and 78MHz. Further decrease in inductance reduces the amplitude of these until they dissappear.
