When I tighten 19 where it is almost full CW, it peaks at around 540 kHz. I can track it up to about 565 but it peaks there. From that point, I can continue to turn CCW but the nut feels pretty loose and it has no affect. 19A does exactly as you would expect on the upper end and feels pretty centered as far as the tuning range goes to 1400.
