Thank you for the update Hans, my mid band kit has the black cores, I just need to finish another project and then I’ll get started with it.
I noticed that you also tided up the formatting in a couple of places, where the images were obscuring the text.
In the latest QMX manual, the instructions for T507 still refer to using 0.6mm wire for the links.
73 and Happy New Year, Nick G0OQK.
