Topband: Binocular Xfrmr

Greetings All:

I wound a transformer for my K9AY array on a Mix 73 Binocular core; 3 
turns primary & 8 turns secondary, with # 26 wire. It is a miserable 
failure on 160, but works well on 75 & 80. Coax is 75 ohms, & load is 
500 ohms. Core was protected to prevent scratching the wire. Winding 
data is from K9AY site, however, it is for Mix 77 material.  Should I 
go to smaller wire, and a turns count of 5 & 13? This turns count has 
worked well on a regular toroid of 43 Mix. Please, any suggestions?

Mike, W5UC
