Better antennas for LF/MF

In order to make loop/frame antennas with higher Q for the low bands (160m, 600m, 2.2km) I have ordered some Litz Wire from across the "pond".

It will be interesting to see how much improvement I can get from this.

"eBay" , of course. It can be a dangerous place, but it is our last, best hope for strange raw materials.

Idea Box : Long Wave SDR

I found those 4.224 Crystal oscillators (ex equipment) on eBay .

Divide 4224 by 32 (first 8 and then make the quadrature signals), and the LO frequency ends up on 132 kHz. Not bad for a 136 kHz SDR.
