Topband: impedance transformer windings

[Steve Flood]

Thanks everyone for the help...

Once I thought about it some, it finally clicked in.......Inductance (uH) = 8.5 (turns^2) for the BN-73-202 core.

All I have for now is the BN-73-202 cores.  I worked up a 3:13 turns ratio and with a 950 ohm load the MFJ 259 reads 50 - j13 on the bench.   I'm going to call this good enough for now and try it out.
