It’s not particularly difficult to calibrate the filter. Since I built a kit KX3, I already had an anti-static mat, and also had an XG3 signal generator. You don’t need the signal generator, but it made things easy. The filter comes with an small wire loop and pigtail that permits you to grab a 16 MHz signal from the rig itself. 16 MHz is close enough to 14 MHz, that you’ll be able to do the calibration.
It’s not hard at all.
