I do CSD work for fun in my retirement as well. Love to tinker with antenna design and other stuff............

Computer control of RF radios, too.............

CSD=CAD, Too much wine and not enough light..............

Have you tried fractal antennas? I've done a little of that, but mainly above 2.4 GHz.

It is easier that way because the size is so small.

I'm not sure I would try it on 3.7 MHz.

Big stuff.
