Topbanders, Pennants are 900 ohms and flags are 950 ohms. Is there any practical concern about using a pennant-designed commercial box in a flag? Do I gain or lose if I use a 950 ohm resistor with the 900 ohm box? If I roll my own with K6SE's recommended FT 140-77 core, should I add another turn to the secondary, e.i. 3:14 instead of 3:13 (or some other ratio) ? 73, Ron WA9IRV
