Hello DK7FC, I have about 17 acres to play with, mainly woodland but with a 5 acre field and a big front garden. I thought an aerial antenna would be a none starter due to the voltages involved, so I
Hello Stefan, I am now on to building a matching transformer but it seems Buerklin have a minimum order of 60 units! I have found this bigger core at Mouser, could I use that instead please? https://
