The matchbox does end up with variable Q, especially when you get a reactive
component. Link coupling really needs a tight coupling so that hopefully the
leakage reactance is minimised. This usually means few turns, tightly coupled.
the Z match does the same, and under some loads, gets enough circulating
current such that at 400 watts, the solder melts and the coils drop off - at
least, in the KW one.
And yes, I did leave Zverev behind......
