Don et al:
I've never tried this, but I've been wondering if any protection would
be given the K2 if there were a reverse-biased diode running from the
+13.8V input to ground. Put a 5 amp fuse in the positive line between
the diode and the power socket and it should immediately blow if the
diode senses a reverse hookup. With a correct hookup, the K2 would get
the full voltage from the power supply. My guess is the K2 might still
experience some damage before the fuse blew, but I'm not smart enough to
know that for sure and I'm definitely NOT going to try it on mine! I
haven't noticed any problems with the series diode.
Just some food for discussion, but let's not have a food fight over it (hi).

Fred,
Not a design glitch IMHO - there is no way that Elecraft can redesign the
float voltage for an SLA battery!! plus:
I for one would not eliminate the series protective diode, so unless someone
comes up with a protective diode with zero voltage drop, we just have to
deal with those two parameters.
