Hi Roelof,I have just completed this core out of N30 Material and 0.5mm enameled cu wire. https://dl.dropboxusercontent.com/u/19882028/VLF/20160514_143109.jpgNot ideal for 6 kHz but it is much cheaper than the ideal material and it works well too. 73, Stefan Am 14.05.2016 14:26, schrieb Roelof Bakker: Hello Stefan, This will certainly work. I have used this a long time ago to build a rf sweepgenerator with a linear V/F characteristic. I gather you will need high mu ferrite. 73, Roelof, pa0rdt |
