Arno,
Also check the connections to the fuse in your power cord. You *DO*
have it fused do you not?
A fuse near the battery is essential to prevent a shower of molten metal
if there is any fault in the wire or the connected equipment. Any
battery stores a LOT of energy.
The automotive blade type fuses are the best for lower resistance
connections.

Hi Don,
You (and Matt) might have a point with the power connection. I connect to
the battery poles (which have the shape of blades) with copper clips, which
are of rather thin copper sheet, so the contact surface is perhaps too small
and too "loose". I will build a better connection next.
My 259 connectors are well tight, so I don't expect any improvement there
using pliers. However, should the battery connection improvement not yield
the desired result, I will look at the 259s (of which I have four in the
feedlines/balun string, plus two female-to-male adapters). Contingency tests
have not shown any issues, though. But that was just an Ohm meter with 3V
running through.
