Hello Joze, LF,

My loop is tuned and balanced with respect to ground. I use a push-pull
preamplifier with two J310 fets, and two bipolar transistors to feed the
coax cable back to the shack. The design was taken from G3LDO's book "The
Low frequency experimenter's handbook" (fig 2.16 on page 30). The schematic
may also be available on the internet, somewhere.

The RX is an ICOM IC-PR1000, which is quite a good RX but is useless at 137
kHz without the pre-amp.
