Re: [Elecraft] Unhook *ALL* connections before Lightning storm

My neighbor in high school worked on lightning arrestors for GE. I’m still sad 
that I never asked to visit his lab.

Re: [Elecraft] My KX3 Battery Approach

Well, I know there is an AA size Li-ion battery, as I have them in my You

67mm battery.

14500 is 14 x 50mm, so it is the AA sized one.

I know I have used the 18650's as well, as they have lots of current

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Bob]

Hi Bill,

No issue with that.   In my mind though there is a big difference 
between  "surge" and "strike".  These may have protected some guys stations 
here, and mine, but a direct hit on my house and for sure all bets are off.


I learned of these from an electrician that swore buy them from his 
experiences on oil rigs off the coast of Louisiana.  They get hit with real 
"strikes" all the time  But they do have a pretty good ground and that must help 
a lot too.


The real world verses the ideal world. Should I spend $3K on a ground 
system to possibly protect a $7.5K ham radio station?  I have second thoughts on 
that aspect too.   I do think that one of these is a better investment than a 
couple of $20 outlet strips that some rely on.


All I have lost here was a telephone modem card years ago.

My best hope is that those on this list who have not seen these or 
other brands may look at them and think that they are not a bad idea.

Re: [Elecraft] Using kio3 won't deactivate k3 speaker.

[Oliver Dröse]

That indicates you either have a faulty 3,5 mm socket on the KIO3 or 
maybe not the right plug (US vs. mm diameter, there was a discussion 
about that a while back). The latter might well be the case as you 
certainly had to use an adapter as the front panel socket is 6,3 mm. I 
would try a different 3,5 mm plug first to rule that out. Good luck!

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[David McAnally]

If you include a lightning protection system in your home and radio station
construction, be sure to perform regular follow-up inspections of the
system.  As lightning protection systems age and corrode, or new
construction or changes are implemented, the system needs to be tested and
evaluated to be sure it can perform when required.

A ham friend does inspection of lightning protection systems
professionally. I got some first hand education when a NWS forecast office
had lightning damage. They discovered after the fact that the building and
tower protection system had corroded and needed upgrading. It was a costly
experience.

My mother lost several items worth thousands of dollars to lightning damage
just a few weeks ago in Oklahoma.  The lack of lightning protection was as
much a factor as the lighting.  Many of the items were connected via UPS
boxes. UPS's cannot substitute for a lightning protection system.  As has
been noted by others, she cannot disconnect everything in the house.
Sadly, she had just settled an ins claim for hail storm damage.  I don't
think her insurance company is very happy with her.

David McAnally

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[George Danner]

As the  CE of a TV station in South Florida we had to contend with lightning 
during about 4 to 6 months a year (spring & fall thunderstorm seasons) in 
the highest lightning strike area of North America.
We did not ever shut down but did go to generator power during lightning 
within 25 miles; as seen on the radar display with lightning strikes 
superimposed.

We had a 1,049' main tower, 2-500' microwave receive towers and a 185' tower 
at the studio not to mention 2 bureaus with antennas on the 3rd floors.
The towers had massive ring ground systems. The rings varied from 20' 
diameter to 30' diameter. each ring had 10' & 20' alternating 100% copper 
rods cad welded to a 4-0 bare copper wire. The ring was attached to the 
tower leg's 20' ground rod with 2 or 3 radials per leg. The tower ground rod 
was set in the foundation to be next to the leg and connected to the leg 
with the least angle. (remember a right angle from the leg is a 1/4 turn 
inductor!). The guyed towers also had a ring ground system around the 
anchor.

All RF, video, audio & data signals going to the tower at the site were 
protected with commercial protectors except the studio tower which was 
replaced with fiber to carry those signals.

We probably took between 6 and 10 direct hits on a good year and many many 
more on a bad year.

The new studio & one of the bureaus had a ground system constructed to 
reduce lightning damage. The building had a perimeter ground system with a 
single point power & phone and the exit panel for RF, video, audio, data and 
dc control. The ground systems was 4-0 copper with ground rods about 10' 
apart.

We did find that our damage was reduced but not eliminated. We never went 
off the air; but we did have periods where we were using redundant (back-up) 
equipment for a while until the main equipment could be repaired.

Our largest reduction in damage occurred once we deployed dissipation 
arrays! These reduce the space charge in the immediate area in hopes the 
lightning choses another location (competitor's tower). My experience with 
towers, satellite antennas & ENG microwave antennas on 50' masts on trucks 
is that the dissipation array is #1 then a ground system followed with surge 
protectors. I would not chose one but all three.

We had a saying at work about lightning protection after repairing extensive 
damage after a bad hit - Lightning protection is akin to elephant 
repellant - just because you don't see an elephant does not indicate the 
repellent actually works. I spent over 30 years in South Florida and would 
never come close to guaranteeing that we had finally done everything to 
eliminate the risk!

Not sure at what point you should stop spending money on lightning 
protection for a hobby should go. For me at my new QTH it will probably be a 
few surge protectors, grounding each mast & tiny tower and a simple ground 
improvement to the house.

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[MontyS]

Ed,

I disagree.  While the bonding and grounding recommended as standard sound 
good, there are times when even that is inadequate.


I had a lightning discharge over my home in NJ - no direct hit, just huge 
induced currents in all cables, wires, etc., in the house.  The hair rose on 
my arm before the discharge.


I lost serial interfaces on a laser printer (no outside connection), Daisy 
wheel printer (same), computer motherboard (same save for AC power, but the 
power supply was unaffected.)


I am a firm believer in disconnecting all cables and wires, including ground 
wires.  I have never had lightning damage when I do so.


We now live in Florida, lightning capital of North America.  The only 
lightning damage I've had is to a cable modem, and a K3 disconnected from 
aerials and power but not my computer.


Monty K2DLJ

So it would be my guess that the important wire connections to
disconnect are the ones that go outside the station:  all ac electric
connections, all antennas, all telco/internet connections.  Interface
wiring between pieces of equipment in one room should not be an issue
as long as the "outside" world is disconnected. That should lessen
the number of cables to disconnect.

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Bill Blomgren (kk4qdz) via Elecraft]

As a side issue - one of the stations down in tampa ended up off the air for a 
week.  A lightning strike melted their heliax and antenna system was destroyed. 
 The antenna was on the top of a bank building (about 70 stories up.)-- using 
the building frame as ground, and then in the ground under the bank building.

The transmitter, luckily, was not destroyed. (significant damage of course)  
However depending on where you are, and the strength of the strike... all bets 
are off.  One station I helped put on the air (which had -2- layers of copper 
plates in the trench between the transmitter shack and the studio with the 
trench under ground had the entire rectifier stack in a Collins FM transmitter 
melted, assorted other stuff there... the lightning then hopped into the trench 
(on the ground) - and destroyed all the monitoring gear in the rack where it 
terminated.


.Of course, that is Florida, where lightning tends to be 2-5 times stronger 
than other spots in the country.

The alternative to disconnecting everything is to design your ham 
station to tolerate lightning events.
There was a very good 3 part series in QST for June, July and August of 
2002 that dealt with the design of a station for lightning protection.  
Those articles are available at 
http://www.arrl.org/lightning-protection.  I highly recommend it.

Some of the "ground rules" given in the article:
All towers and masts grounded with buried radial wires and ground rods 
to spread the impact of a strike over a large area of the earth.
Perimeter ground wires around any building with a driven ground rod at 
each place the wire changes direction. (lightning likes to travel in a 
straight line).
Bring all services into the ham shack through a common grounded copper 
panel fitted with suppression devices - that includes feedlines, power, 
CAT5 cables, phone cables, and everything else.
Keep any equipment or devices that are not powered/connected through the 
above panel out of reach of the operating position.

There is no guarantee that the above steps will eliminate failures due 
to lightning, but it will go a long way toward achieving that goal.  The 
real goal is to keep *everything* in the shack at the same potential 
during a lightning event.

I have attempted to use those guidelines in the construction of my shack 
and antenna field.  All my feedlines are automatically grounded when the 
station is turned off, and I do not attempt to operate when there is 
lightning nearby - and I get stay out of the shack during storms.
We had a lightning event here last year that took out the Ethernet 
router, several switches, 3 computers and 2 network attached printers.  
None of the ham gear was damaged.

Don W3FPR

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Edward R Cole]

I found John, K9UWA's reply very interesting.  Seems a how-to manual 
is needed for folks exposed to lightning and wanting protection technology.


I am fortunate to live in a nearly lightning-free area.  We hear 
thunder maybe one time every 3-4 years and I have only experienced 
actual lightning activity during an hour long freak storm about 2 
years ago.  This experience is over 35-years living 
here.  High-winds, earthquakes, tsunami's, volcanoes - 
yes!  Lightning -no.  ...oh and winter!


The only time I hear lightning crash static is when propagation 
favors hearing from areas that have lightning.  Most of the time 
80/160/600m is static-crash silent.  600m is quiet all year long.


So it would be my guess that the important wire connections to 
disconnect are the ones that go outside the station:  all ac electric 
connections, all antennas, all telco/internet connections.  Interface 
wiring between pieces of equipment in one room should not be an issue 
as long as the "outside" world is disconnected. That should lessen 
the number of cables to disconnect.


My station would be a nightmare to disconnect with 17 coax lines and 
probably 2 dozen ac cords to disconnect.  Then there are the multiple 
rotator and control lines, some of which run directly to tower tops 
(four towers and a dish) with no break.  That's what you  get running 
on 14 separate bands from 600m to 23cm!

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Rich - K1HTV]

I agree with Brian, its not very easy to pull off all wires and cables if you 
have a complex setup with multiple antennas and radios with many cables 
attached. In the K1HTV Ham shack I use my K3 and a few other radios on multiple 
modes on the HF, VHF & UHF bands.  Rather than removing all cables each time a 
storm is in the area, it is much more important to focus on installing a 
excellent ground system. 

Here at the K1HTV QTH, I've installed a perimeter ground around the house with 
8 ft ground rods every 16-20 feet. The 77 ft tall tower with HF, VHF an HF 
antennas on it. An array of 8 ft long ground rods fan out from the tower and 
are connected to it and to the perimeter ground wire where it passes the tower. 
All coax cables from the tower to the shack are at or below ground level and 
enter the shack via 'UHF', 'F' or 'N' Female-to-Female barrel connectors 
attached to a steel box. This box is also connected to the perimeter ground, 
using 4 gauge wire. Rotator and control cables from the tower enter the box and 
each wire is protected with gas gaps to ground. The shack ground and the AC 
power panel are both tied to the perimeter ground system so both are at the 
same potential. If this isn't done, a large difference of potential can be 
developed in a lightning strike. The shack has a single point ground which 
connects to the steel cable entry box. Where the coax cable leaves the
  multi-port HF antenna switch to be connected to the K3, there is a gap device 
to ground via a UHF Tee connector.

Using good grounding techniques, in my 56 years of Hamming I've never lost a 
piece of Ham equipment to lightning. That's not to say that there won't ever be 
a direct lightning hit that will cause damage. For now, I plan to continue to 
leave all equipment connected. Its just too impractical to disconnect 
everything.

Just make sure that your household insurance is paid for and that it covers 
lightning damage.

Rich - K1HTV

= = =

This sounds like good advice.  However, every connector socket on my K3 
is populated, ditto the computer, ditto the KPA500, ditto the KAT500.

Pulling all wires when there is a potential storm threat is totally 
impractical.  Even if I did, I'm sure some of the connectors would 
simply not last.

I suspect others have similar situations.

Re: [Elecraft] KX3 fails to power on.

[Colin]

Thanks Bob
Have checked the ribbon cable, even swapped one over from another KX3. If the 
KX3 is switched off for a couple of hours it will power up again. When I 
managed to power it up that seemed a good opportunity to reload the firmware 
which I did. After reloading the firmware I did the usual reboot only to be met 
with the 4 LEDs on again and no other sign off life. .

[Elecraft] Elecraft Everywhere at WRTC...

[Gerry Hull]

Hey Folks,

Elecraft was everywhere, and not just with many of the 59 WRTC teams...

We had a blast at the HQ Hotel while the teams were out in the field...  We
ended up having FIVE remote stations in the demo room at WRTC, along with
the WR1TC local station:

PR1T in Brazil, SK9HQ in Sweden, the RemoteHamRadio Blueberry Hill, NY QTH
as W2PV, Mt call running at K2LE/1 Vermont, and N3AD running single-op to
his home QTH.  Tree, N6TR, showed up to operate his Oregon remote, but we
ran out of table space -- so he operated from the IT office (for a total of
six K3 remotes).

All these remotes were all K3/0 minis running with Microbit RRC boxes on
the remote end.

Check out this video from the remote operating position at PR1T (It was
Eric, K3NA, at the WRTC HQ End...)

https://www.youtube.com/watch?v=ffppq4WOHqY

A great time was had by all!

73,

Gerry, W1VE

[Elecraft] WRTC 2014 Winners and Elecraft

[N6JW]

Now that the unofficial results are in for WRTC 2014, and K1A (Craig, N6MJ 
and Chris, KL9A) seem to have the #1 spot to themselves, it would seem 
that congratulations are in order.

1. First to two fine contest operators who have been climbing in the
rankings!

2. Secondly to youth!  Both are in their low thirties . . . maybe they can
stay
awake and alert better than the older guys :)

3. But thirdly, it seems that congratulations to Elecraft are in order!  We
do 
know they used K3s in Moscow last time (WRTC 2010), and earned the top 
US team score; #1 in QSOs and #3 overall.  And while I am not certain 
about this, according to the video clip below they planned on taking two
K3's with them this time (and a Mk 5 as a handicap :)

See the following video interview clip from DX Engineering:

http://youtu.be/OppRRdLfB6o

Intended equipment is mentioned around 5 minutes 30 seconds into the 
interview.

While I worked several of the WRTC contest stations on different bands,
I did not work K1A, so it is obvious they won on strategy :)  Don't waste
time with US causal operators :)

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

Obviously the answer is NO they don't disconnect and they don't even turn
their equipment off. Yet is survives direct lightening hits on their towers and
equipment.


I volunteer for KBBF-FM, the local bilingual community broadcast station 
here in northern California.  The antenna is on top of Mount Saint 
Helena, north of Santa Rosa.  Compared to some areas of the country, 
lightning is not common here.


However, about three years ago the electrical pole that feeds the 
transmitter shack was hit by lightning.  The pole exploded and ended up 
in pieces on the ground:


http://kbbf-fm.org/images/DamagedPoleM.jpg

The electrical service entrance meter was blown off the wall.  We found 
it lying in the grass about 30 feet (10 meters) away from the building. 
 The main transmitter was fried and had to be removed for repair.  The 
950 MHz STL (Studio to Transmitter Link) antenna was also damaged beyond 
repair but, surprisingly, the STL receiver itself survived.


After repairing the electrical wiring inside the building we were able 
to get back on the air using the backup transmitter, the backup STL 
system and the emergency generator.


I think the moral is that it is pretty much impossible to absolutely 
protect against a direct lightning strike.  If I lived in an area where 
thunderstorms were common I would make my station as lightning-hardened 
as possible and ALSO disconnect everything when a storm is imminent.

I've had this happen a number of times after I've unplugged the serial

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Fred Jensen]

No.  I supported myself in college working at KSBY-TV in San Luis Obispo 
at the end 59 and early 60's  Our studio and TX were located on Cuesta 
Ridge overlooking the city, directly adjacent to the base of the 400' 
tower.  In the building, the multitude of cables [mainly 75 ohm coax] 
ran in trenches in the concrete floor, which were covered with 1/4" 
removable steel plates.


Lightning strikes [common in storms] only put us off the air once that I 
remember, but caused a totally deafening "clang" from all those trench 
covers. :-)  The one time we went down was just a popped breaker on the 
mains to the 10 KW visual PA, the aural PA stayed up.  We never lost any 
equipment to lightning.


Unplugging all the cables behind my K-Line, an area that gives new 
meaning to the term "wireless", would happen exactly once.  I'd never 
manage to get all of them reconnected.

[Elecraft] K3 Receiver troubleshooting

[Rick Stealey]

My K3 suffered a sudden loss of sensitivity this morning.  Yes, there was 
lightning last night.  The antenna input was grounded in an antenna switch but 
the receive antenna port was connected to a Beverage. 

It appears to be normal in every other way.  Transmitter ok.  Receiver 
functions work, like preamp, attenuator.  But the level is down >60 db.
It is the same on both the antenna jack and the receive antenna port on the 
KXV3.

I have some lab equipment (HP sig gen, spectrum analyzer) and made some quick 
checks but I need a sanity check:
With -40 dbm into the receive antenna port the S meter is S7.  
With -30 dbm input, The spectrum analyzer connected to the IF output shows -80 
dbm.  I'm assuming this is WAY off, and should approximate the level of the 
input signal.

So I think I can safely assume the problem is not in the IF or downstream, but 
a likely culprit would maybe be a switching diode in the receive path?  Any 
ideas?

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Don Wilhelm]

The alternative to disconnecting everything is to design your ham 
station to tolerate lightning events.
There was a very good 3 part series in QST for June, July and August of 
2002 that dealt with the design of a station for lightning protection.  
Those articles are available at 
http://www.arrl.org/lightning-protection.  I highly recommend it.


Some of the "ground rules" given in the article:
All towers and masts grounded with buried radial wires and ground rods 
to spread the impact of a strike over a large area of the earth.
Perimeter ground wires around any building with a driven ground rod at 
each place the wire changes direction. (lightning likes to travel in a 
straight line).
Bring all services into the ham shack through a common grounded copper 
panel fitted with suppression devices - that includes feedlines, power, 
CAT5 cables, phone cables, and everything else.
Keep any equipment or devices that are not powered/connected through the 
above panel out of reach of the operating position.


There is no guarantee that the above steps will eliminate failures due 
to lightning, but it will go a long way toward achieving that goal.  The 
real goal is to keep *everything* in the shack at the same potential 
during a lightning event.


I have attempted to use those guidelines in the construction of my shack 
and antenna field.  All my feedlines are automatically grounded when the 
station is turned off, and I do not attempt to operate when there is 
lightning nearby - and I get stay out of the shack during storms.
We had a lightning event here last year that took out the Ethernet 
router, several switches, 3 computers and 2 network attached printers.  
None of the ham gear was damaged.

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[John K9UWA]

Do TV Stations and Radio Stations and Cellphone towers disconnect all 
their equipment everytime there is a storm in the area?

Obviously the answer is NO they don't disconnect and they don't even turn 
their equipment off. Yet is survives direct lightening hits on their towers and 
equipment.

In other words there are ways that you also can protect your equipment 
without disconnecting it. You need a well designed ground system. This 
means a single ground system for everything that is in your home or a part 
of your antenna system. During a direct strike on the tower 90% of the hit 
should be bled off directly to ground through the ground system made up of 
many ground rods all connected together by proper copper connection. This 
leaves around 10% of the hit left for all the "Devices" that are connected to 
all the metal anythings that come and go from your home. Includes incoming 
power lines Telco lines Cable TV lines as well as all your rotor control lines 
relay lines and coax cables from the antennas. Anything that is metal that 
comes and goes from the house needs a protection device on it. 

I have three towers the tallest has antennas up to 175 feet above ground. 
The tallest trees here are around 70 feet high. So the towers get hit many 
times. They have been up since 1988. During the summer of 1989 I had a 
major hit on the tall tower that destroyed nearly everything in the house. TV 
sets microwaves all radios all computers many coax cables and other wires. 
But I learned the hard way to protect my system. I was placed on High Risk 
Homeowners insurance and the company that was assigned my insurance 
said I had 30 days to either get a proper ground system installed of get 
those towers all on the ground. We installed 100 ground rods all connected 
together by 1200 feet of 3/8" ID copper tubing. We installed a single point 
ground window where all the cables coming and going to the towers enter 
the house. Every wire has some sort of protection device on it. The main 
power line coming to the house has a protector device on it. The towers and 
antennas have since then withstood many strikes by lightening. Many 
surges from hits down the road that come in on the power lines. All with 
ZERO DAMAGE to anything in the house or on the towers. I did get lots of 
help from the techs at Polyphaser regarding how to build the system and 
how to install it. Total cost of this grounding system in 1989 was around 
$3,000 for all of it. Zero Labor as I and a couple other local hams installed 
all 
of it. Today we operate the station remotely during part of the winter so no 
way to unhook and rehook any of it. 

So you too can be safe and not worry about blowing up your equipment.

Re: [Elecraft] Unhook *ALL* connections before Lightning storm

[Bill Blomgren (kk4qdz) via Elecraft]

The question is "how long are they?"  - Ethernet cables are typically 6-20 feet 
long.  A jumper between the rig and amplifier, much shorter.

Length determines how well it acts as an antenna.  The cables I worked with 
were perhaps 20-50 feet long, and made good antennas.  Some of the ethernet 
cables in my apartment are 50 feet long to feed from one extreme to the other. 
(I do video editing and need at least gigabit end to end...)

Telephone cables will be LONG.  Unplug anything connected to dsl or phone lines 
in general.

Luckily, the apartment I'm in has underground utilities.. However, that nice 
shot of a tower on the ground getting a direct strike was interesting.

It shows that having a few high trees around that are much higher than the 
antenna are NOT a reason to not disconnect. 


Lightning looks for an interesting way to ground.  Don't encourage it by 
leaving lots of paths in the shack available.

Down in Florida, there are code required surge MOV's in every circuit breaker

Down in Florida, there are code required surge MOV's in every circuit breaker 
panel.  All they do is eliminate something close by.  They get vaporized by a 
direct hit.

Subject: [Elecraft] Unhook *ALL* connections before Lightning storm
 

Hi all, I work on K3's all day and would like to advise/remind folks 
that lightning comes in through ANY path it pleases, not just the antenna.
Time and time again folks say they unhooked their antenna but the 
lightning took out the DSL modem, computer and K3 via the RS232 port!
Anything connected is a potential path...
Be safe! '73

[Elecraft] KX3 fails to power on.

[Colin]

Hi all
Switched on my KX3 this morning, the LEDs. lit up and stayed on but nothing 
else. Had to removed the batteries to clear the LEDs. Tried the external PSU 
with and without the batteries installed with same result. Anyone any ideas?

Doesn't have to be high above ground or the highest thing about either.

The mast in these photos in only about 8ft AGL.
