Would it be possible to get a small usb card (96 kHz) and use NAA on 24 kHz as a referece to send and receive EbNaut with the Raspi3? Tinkering on 8270.007 Hz resulted in 0.4 amps briefly until a coil fried. The pie configuration with 24*0.08 mm wires gives 0.5H at 150 ohms with less than 2kg of copper but dealing with volage gradients is a challenge. At the moment the VLF TX is on with 0.3 amps. 73 Joe On Fri, 23 Jun 2017, DK7FC wrote: > Hello Joe, > > Does that mean that you can decode EbNaut now, for example on LF? :-) > > 73, Stefan > > Am 23.06.2017 21:19, schrieb jcraig@mun.ca: >> Problem solved.
