Antenna was a full sized 40 meter vertical made of 1.5 inch diameter
aluminum tubing (surplus military mast) over 10 34-foot radials of #18
PVC insulated wire.  There was no matching network.

Station design consisted of the K3 sitting on a cooler operating from
12 volts fed from the car.

Note that the first 3 contacts were made with the radio switched to RX
input which had no antenna other than leakage from the transmit
antenna.
