Unplugging the radio to protect it

[Arthur Nienhouse]

*/I had an event several years ago where something hit Charter Cable
several miles away the hit came in through the internet cable, hit the
modem took out everything connected by
Ethernet cable back to the Motorola Modem.
The list includes .....
Motorola Modem
Wifi router
Magic Jack Plus
Dell 8400 that was connected via the Ethernet cable
And U1 I think it was on the K3 ki03 board which was connected via cable
to the Dell 8400.

There never was a lightning event that I saw or heard, if the Dell would
have been connected to the Wire Less WIFI and not hard wired via a cable
the radio and computer would have been ok.
I took the ocasion to send the radio back to Elecraft and have it
updated there service is better than the best I sold a house full of
Yaesu gear and never looked back.

Regards

I do not unplug anything when not in use.  Never had a failure from
doing that.  I do live in a virtually lightning free environment but
static buildup in dry winter winds can happen.  This is why having a
shorted RFC across antenna lead -in or back/back diodes on RX input
are used.  System is all grounded to central point going to outside
ground rod and one tower has a ground rod for HF radial system (and tower).

Many years ago I was comm officer on a BLM Wildfire sitting at Base
Camp at 2400-foot on a mountain ridge in AK when a strong wind blew
up in advance of a storm.  We used VHF MOT HT's connected to whips
mounted on 30-foot fiberglass telescoping masts (for quick
deployment).  Operators complained of getting shocks from the radios
which I dismissed until I tried picking up one sitting on the tundra
and drew a 4-inch arc - ouch!  Radios totally survived this.  We left
the radios lying on the ground until the winds subsided.

I own nothing made by Kenwood.  Guess now I never will.  Mostly
Elecraft at the present with some older MOT and Yaesu VHF stuff.  In
my opinion Kenwood long ago lost out to both Icom and Yaesu...and, of
course, Elecraft.  I wonder if a letter to the CEO of Kenwood would
have any effect.  Otherwise write this up in every ham newsletter and
on-line review.  That works for Consumers Report.

At work, I specified models when buying and we converted all to MOT
over from some GE/Ericson and a few Sinclair.  Reputation for quality
and backing the customer.

I usually disconnect antennas when away but keep the power connected.

Last time going for a month-long vacation I disconnected all power. After reconnecting, there was a loud bang  and Expert 2k-fa was gone.

Sometimes the cure is worse than the disease.

In addition to disconnecting all antenna cables and the single AC power
cord for all but my remote base radio (not connected to any other shack
gear), I unplug AC power and the DSL cord to my MODEM/router.  I lost the
previous router (and many other devices) during a lightning strike years
ago.  CAT5 cable conducts quite well!
