It's better to replace it to avoid shortcuts. The provided wire for the power chocke ( 2 turns ) has a weak coating. ![]() ![]() ![]() I used the low pass data from W3NQN for a 7 element Chebyshev with standard value silver mica capacitors and T68-6 toroids. Construction is easy but a lowpass filter for each band is mandatory. Supports for the transformers need to be cut out of the pcb. The 0.5 turns windings are on the PCB by means of the tubes inside the toroids. ![]() Capacitors are 10nF instead of 100nF as shown in the schematic but that's not a problem. My first impression : High quality PCB ( 100 x 50mm ), all parts in the kit including 2 power FETs type IRF530N.
