Okay
Here is another idea. Full disclosure, I'm not an engineer, and many here are much more knowledgeable, experienced and have far better test equipment than me. I do understand the basic math of resistance , reactance, resonance, etc. I also realize this idea is not in keeping with modern, minimal knob technology. Feel free to educate, debunk, etc...I won't take offence.

Would it be possible to construct a simple, tunable bandpass filter, to go in series with the antenna, or between the driver and the final. QRP, so old air variable cap should work. Just throwing the idea out there...
