Many tnx to all who replied offline with advice and help. I am on the right track and hope to complete the project today.
73 Frank VO1HP ------------------------------------------------------------------------------------------- I am in the process of building a pennant. I'm stuck on the right way to wind the transformer. I have Type 73 binocular cores but am not clear on how to do it. I am feeding the loop with RG6 and my terminating resistor is 910 Ohm 2%. The transformer will go at the point of the pennant and should be 12:1 ratio ? For 75 Ohm cable K6SE info sez - 2 turn primary and 7 turns secondary. I see on W7IUV website he sez - wind the primary on first. --- so for two turns I do this: one turn is: - up through one side and down through the other side. another turn is - continue up one side and down through the other --- that makes two turns...is that correct? Winding 7 turns would follow same procedure winding the wire over the primary wire and have the leads out the opposite end of the core from the primary? I hope you can follow my primitive description. Am I on the right track? 73 Frank VO1HP _______________________________________________ Topband reflector - topband@contesting.com _______________________________________________ Topband reflector - topband@contesting.com
