Allan, If the MFJ in question is a "tapped coil" design, and you don't mind messing up 15m a bit, you might try moving the 15m tap a turn or two and see if it will fall in line. I've had to do that with Drake tuners in the past to get to the spot I wanted on 75m. Just a thought, and easily reversed if 15m becomes more important. 73, Don, WB5HAK
