Winding Toroid for 80M Band Pass Filter
Winding a toroid for the 80 meter (3.5 - 4 MHz) band pass filter. I use a small carrier made from a section of 0.100" perforated Vector board, with the toroid held in place by a small zip tie. This allows the toroid to be firmly mounted on the Manhattan circuit board taking the strain off the toroid's small wires. I hope you find this helpful. Keep building! - 73 - Rick - N3FJZ
