[Elecraft] ERR IO3 AGAIN

[Jim McDonald]

Besides other grounding and lightning protection, which have been covered
very thoroughly here several times, I have a last line of protection on the
RS-232 input to the K3.  It's manufactured by (for?) Tripp-Lite and sold as
a model DB9.

I'm not suggesting that it replaces any other lightning or surge protection,
but for $15 or so, it made me feel better.  Amazon sells them (what a
surprise!):

sr_1_1?ie=UTF8&qid=1304176459&sr=8-1 

or http://tinyurl.com/3d882eq .

I also have them on my SteppIR controller, HAL DXP38, and Green Heron
controller too.

Some will probably say they are a waste of money, assuming you have a good
protection system, but at $15 each, redundancy made sense to me.

Tue night severe T'storms came through the Monroe, LA area. I lost my
computer the the Comcast link. After that is when the ERR IO3 made itself
known. I'm sermising I receive a spike through the RS232 cable. Is this
possible? My antenna were disconnected along with power.
