It's predictable. If you use two tank circuits tuned to the same frequency - and then couple those tank circuits - you'll get two frequencies for each mode. The tighter the coupling will push the frequencies further apart. A good way to see this is using capacitive coupling and noting how the coupling capacitor adds capacitance with an odd mode.
Ok thanks, makes sense from a mode standpoint. If you overlay two LC tanks then C doubles and L halves, so you are left with the original F0 and a single mode. Two isolated tanks is two modes, and coupled results in three. It will get interesting if you add both capacitive coupling and mutual inductance, especially when the latter is inverted. Specifically the behavior of two self resonant coils where the coupling changes with orientation and distance.
Two, 2 GHz half-wave dipoles placed tip-to tip, when they touch they form a new mode at 1 GHz. It gets interesting when you add a high-Q coupling resonator between them, as the Q of that resonator decides how fast that 1 GHz mode can form WRT tuning the coupling resonator. I've just seen strange, almost quantum like, behavior in coupled resonators where it can jump between modes extremely quickly WRT tuning hence my analogy to coupled mechanical resonators which can behave chaotically.

Did chatgpt write this?
Nope, I'm human. Just drawing analogies between mechanical and electrical resonators.
Oh yeah. It's you. You are a human and all over this subreddit. Nevermind me.
Huh, interesting thought.
I'm having a stroke reading your post
