Thread subject changed to reflect the actual topic.
It is the station owner that is responsible for lightning protection (or
other environmental risks); not Elecraft or most any product vendor of
any type. To require more, would cost more (for the hardware and for
the liability risk that the
Hi again,
Your grounding sounds good. I suspect the USB connection used by
Elecraft was standard, and not something that was lightening proof, so
yes, any manufacturer can do more, the question is why increase the cost
of the amp to everyone, when there is little chance the protection will
Hi Dave
I have a panel like yours, each antenna to a discharger, on a copper sheet.
Nothing has happened with the coaxial and antenna switch
I have several rods that make the ground and a copper bar behind the desk
and all the equipment is connected to the ground
The lighting came through the
Jorge,
I can only go by what you said:
"Last week I experienced a lightning strike"
That sounds a lot like a direct discharge into the shack, so I am
responding to your comment, if that is not correct, please help me
understand what actually happened...
Lightening is strange, it can take
Good Evening,
It has been a cold, wet, snowy week. My daffodils look fresh due to
the chill. They last for weeks during the end of winter. Birds are
settling in. A few woodpeckers are making homes.
The sun is very active. Multiple CME hits and near misses, with
another due
Supported myself during college at the local TV station ... very late
1950's. Station was on a ridge, we got lots of lightning strikes on our
tower. The grounding ["earthing"] of the entire station was super
extensive. We still occasionally lost equipment, mostly the smaller
uwave equipment
Probably a great device, but why would Elecraft risk infringing someone else’s
patent and increasing the price of the K4 by an extra $100, rather than letting
the individual decide if they need and buy their own?

hi Dave
I don't know what to tell you, I imagine that a direct discharge into the
shack would have burned everything.
I had 6 USB cables connected to the laptop, they burned the USB of a box of
GHE that costs $160 and the USB of the KPA1500 that costs +$7000
rotor controls and other PCs did not
Hi Jorge,
That device would not stand a strike... As per the US Weather service,
(https://www.weather.gov/safety/lightning-power), a typical lightening
bolt runs around 300,000,000 volts, at 30,000 amps. That device is
speced for 4000 volts...

I am not an engineer and I don't know anything about electronics either,
but I am very receptive to the solutions that many radio friends give me.
which made me think if the kpa1500 or k4 usb was built with something like

I can’t see where a more robust USB connector would affect remote operation via
a LAN cable.
Better isolation can be obtained by installing a WiFi dongle.

Jorge,
I would imagine if you approach Elecraft with that mindset, their
thoughts will be you should take care of your own lightening protection.

Kevin, KD5ONS, in OR runs a CW net on 20 [14050 +/-] at 2000Z? and
another on 7050 or close at 2300Z on Sun. Not sure of the times but he
usually posts the notice here each week. There is at least one other
SSB net but don't know the details since I lost my microphone.

Hi there,
Is there a listing of the Elecraft nets that are on the HF bands? I seem to
recall there was one on 20m but don't recall the schedule.

Please help support this email list:
* Elecraft has no control in how one sets up (or uses) a station.
* A remote station needs all of the same protection enjoyed by any
other station; they are the same except one is used remotely.
On the last premise; set up the remote station as if it were any other
station; RFI and noise
of course that we need to take care of many things, very good grounding,
gas arrestors, single antenna grounding panel, etc, etc
but, after my bad experience, I expect that a expensive product that is
designed, in many cases, to be installed remotely, has been, for example on
the USB connector,
I don’t think you can expect Elecraft to take care of any safety issues,
especially with lightning.
You could install a remote camera to keep an eye on things, along with smoke
detectors and some form of extinguisher, such as those now available for 3D
printers.
To protect from lightning,

For me, Remote has added an unexpected new dimension to HF QRP operation.
