Not really, not for this particulair situation, it is a general question. But I am building an VFO circuit with such a transformer which requires 16 turns in the primary and 8 in the secondary. It is T6 in the circuit by K8IQY and is part of the 2N240 QRP rig which is published on his website www.k8iqy.com. (The numbering of the windings is a little different there than in my sample, but the idea is the same). It uses many toriods which have to be wound by the builder, and caused me to post the question. It would be helpfull if you could indicate how to wind the many different toroids, with my posted question as a sample.
