Well if you keep your head about you, the harmonics don’t necessarily have to be an issue. Remember square waves just generate harmonics… and at known locations so trimming a resonate circuit to 7.0 MHz from 7.2 MHz won’t see much of an issue. It might if you were trimming to a harmonic frequency, but the fundamental will always be higher amplitude.
I like the German DIPIT kit a lot, but at 150+ euros it’s a non-starter. I’ll see if I can design up something simple (read that CHEAP) that does the same thing.

Ahh, good point. Square wave bad, sine wave good.
