I found Gary, K9AY's, response to Louis's questions on the K9AY receiving
antenna very interesting and as a result I have decided to change the FT-143-43
toroids in my K9AY to the Amidon binocular type he mentioned.
When I contacted Amidon to order some of the new cores I found that the
FB77-6301 only has a single hole and is not binocular. They also said the
don't make a binocular version made with type 77 material.
Does anyone have the correct supplier and part number ?
