With Gerard, PA2G I am working on a magnetic loop antenna.
I have started with the Magnetic Loop Controller. The design of the controller is from Loftur, TF3LJ / VE2LJX.

Frederik, ON5AI provides nice DIY-kits for this design
The hart of the circuit is a Teensy3.2 controller. I am using a steppermotor 17HS4401, which will drive the Vacuum-C of the antenna configuration.
There will be some interesting challenges: housing of the SWR-pcb, housing of the controller, interface with the HF radio, etc.
