Cushcraft Trap Coaxial Capacitor Repair
There are occasions that the coaxial capacitor on Cushcraft trap R5, R7, etc. fail due to a breakdown of the insulator between the outer aluminum tubing and the inner capacitor rod

High-Q Coil Construction Techniques
High-Q coil inductors have something in common: the length of the coil can only be slightly longer than its diameter. In other words, high-Q coils have cube-like dimensions

Helical Coil
The inductance and self capacitance of a helical coil can be determined by entering its dimensions in the boxes above. The length of wire used is also calculated
