[Elecraft] K3 inline fuse

[David Cutter]

You are much better off using the current limiting feature of your dc 
supply.  A fuse is not fast enough to protect any electronic circuitry. 
Strictly speaking a fuse in line is rated to protect the cable in the event 
of a short circuit in the rig which would be a very big fuse, far bigger 
than your psu is rated to supply most likely.  Fuses and their holders are 
too slow and drop valuable volts along with the cable drop and connectors, 
which all add up to a poorer distortion figure on transmit.
