Re: [Elecraft] (ot) noise reduction resources

2024-04-05 Thread Fred Jensen

FWIW: I see that regularly, in short bursts.  Midday, just watching 80 
while otherwise occupied, those multiple very narrow carriers come up 
for anywhere from a few seconds to a minute or two, and then disappear. 
Oddly, but thankfully, I'm not plagued with SMPS type noise ... well, 
except when I was trying to work TX5S.  I don't know what the carriers 
are from but they look like a steady CW carrier, not noise.


Any email list on mailman.qth.net will strip all but plain ASCII text. 
Emails sent in HTML likewise.  It's not Elecraft censoring anything, 
just the way the email list software is built.

Re: [Elecraft] (ot) noise reduction resources

2024-04-05 Thread Jim Brown

Elecraft's own list is for support of ALL their products.  Some guys 
wanted a list dedicated to the K3, so started their own. That's the 
groups.io list. There's another groups.io list dedicated to the K4.


Elecraft is NOT doing censorship, it's simply a text only list, because 
they started it 25+ years ago. I started reading it in 2003 when I 
bought a used K2. I'm not aware of them ever censoring anything. Indeed, 
the two owners of the company read their list every day and have been 
known to chime in to solve problems. Several times over the years, I've 
seen Wayne or Eric get involved to solve problems with guys on remote 
DXpeditions.


WE6R is one of several hams who work on a service bench there. He's been 
reading the kK3 list for a year or two. I think Wayne and/or Eric might 
browse it now and then. I live about 20 miles from Elecraft, so know 
these guys and several others.

Re: [Elecraft] (ot) noise reduction resources

2024-03-29 Thread Michael Carter via Elecraft

Hi Robert,

You've used the term 'receiver noise', but specifically
mentioned heterodynes and harmonics as being of
concern.  All receivers, Elecraft not excluded, have
internal spurious signals generated in the VFO and
BFO circuits as well as clocks for digital circuits in the
radio.  The best way to identify internal spurious signals
is to remove the antenna(s) from the radio, terminate
the antenna ports in 50 ohm dummy loads, and then
carefully sweep the bands of concern to see if anything
is audible.  Internal spurs will typically be insensitive
to front-end gain/attenuation settings, but may vary
in strength with IF gain controls (e.g., the K2 has IF
gain control even though labeled as RF gain).  If
you have a second, different radio, try the same experiment
and see if the spurious carriers are replicated on it.

Switch-mode power converters are ubiquitous these
days and generate buzzy, drifting harmonics of the
switching frequency.  Turn off power to your entire
house, power your radio from a battery source, and
see if you still hear such signals.  Finding these sources
is easy, if a bit time consuming, once you've determined
they're on your local AC circuits.

Ethernet signaling is long understood to generate
clock/data signals that are audible in the ham bands.
These signals can be identified once found on the
receiver by turning off (including any UPS-powered)
routers/switches that use Ethernet cabling.

Dave, NK7Z, has a nice tutorial on methods to
identify RFI sources generally:
https://www.nk7z.net/category/info/rfi-mitigation/i-have-rfi-series/

It sounds like you've done the good work of
grounding and bonding, which can help with
self-induced RFI (ask me how I know!), but it
won't address RFI sources such as internal
spurs in the radio or the other predominant
sources cited above.

73,
Mike, K8CN

[Elecraft] (ot) noise reduction resources

2024-03-28 Thread Robert Strickland via Elecraft

I'd appreciate any info on sites/resources to help with receiver noise 
mitigation. I'm especially interested in identifying the source of 
heterodynes and harmonics that appear on some bands but not others. 15m 
seems to be particularly vulnerable. I'm familiar with W9YC's papers on 
this topic [very good]. The station here is all Elecraft and pretty well 
bonded and grounded. Thanks in advance.

Hi all,

I'm activating the Pennzoil 400 at Las Vegas Motor Speedway usingrhe
Elecraft KX3 and KXPA100.  I'll mostly be around 14.6mhz for a few hours
during the day all weekend if you'd like to make the contact.

Re: [Elecraft] OT: Elecraft K2 serial #00001 -- our very first production unit -- is looking for a new home

2024-01-01 Thread W3FPR

I too have a Field Test K2 S/N 00020 that is fully upgraded and tuned.  
It has all options except the KPA100 installed.  It also has the now 
unavailable K2XV transceiver interface and a Keyout Jack on the rear 
panel.  Functionally it is equal to a newly built K2 plus options that 
are now longer available.

It does have the KAF2, but not the KDSP2.

If it will go to a radio museum, it will be donated - otherwise make an 
offer.  Money back within a month if you are not satisfied.

Sounds like Bob Milne has two brains, or perhaps he’s using left and right side 
for the same purpose. He’d certainly give so-called AI a run for its money. 
Remarkable.

Well done with the harmonica and guitar. I’ve seen it done but not tried it 
myself, mainly because I’m abysmal with a guitar. 藍

Another guy I’ve seen perform an odd feat was the late, great Jackie Brown, who 
was obviously listening to some guy playing an electronic keyboard and must 
have heard a wrong phrase. Jackie walked over to the console, leaned over the 
back and proceeded to play the piece “upside down” and in the same key, 
remarking “that’s how it actually goes!”

With your discrimination, it seems you might get an extra duty as a tuner. 藍

Re: [Elecraft] OT: The 4-track mind

2023-12-14 Thread G4GNX

Actually with Theatre Pipe organs (as opposed to trackers) the key press to 
pipe speaking is almost instantaneous except with some bass pipes which are 
naturally a bit slow - it takes some time for sound to travel the length of a 
16’ or (worse) 32’ pipe, or if a particular magnet is a bit reluctant to 
operate.

The real problem is where the pipe chambers are situated a long way from the 
console. The worst one I played was in the Sutton Plaza (UK) which had a delay 
of over 2 seconds. The only way to deal with it is to close your mind to the 
sound and rely on your inner clock to get your timing right when playing 
rhythmical pieces. A bit like listening to a QSO that’s buried in the noise. 
The human mind (when trained) can be quite adept at selective listening.

Many Theatre Organs also have a piano attached and that can be just as 
disconcerting if the piano’s a long way from the organ console.

Thanks for the kind words David. I too like Ragtime, especially Joplin.

You have some great Theatre Organists in the USA. If you fancy a good concert 
sometime, keep an eye out for Dave Wickerham, Walt Strony and Clark Wilson. 
There are many more, but I’ve used enough bandwidth already. 

Re: [Elecraft] OT: The 4-track mind

2023-12-13 Thread G4GNX

Yeah sight reading too, but it can be a pain. Unless the score is written for 
Theatre Organ i.e. with 3 staves - the bottom one being the bass line, with 
only 2 staves (such as a piano score) the pedal work does have to be 
improvised, whilst sight reading (usually) chords and melody. Sounds like Skip 
was really proficient at playing the pedals.

I find the piano more difficult because it relies on touch and finger pressure 
to implement expression, whereas the organ usually relies on just selecting 
notes on the keyboards and using an expression pedal to control volume.

There are a couple of sneaky tricks that can be put to good use. 2nd Touch is 
often used where you press the keys normally and you hear a selection of 
voices, but pressing the same keys quite hard against spring pressure a further 
set of different voices will be added. This can sometimes be implemented by the 
pedals, but it’s not found on many organs.

The 2nd ’trick’ is called Sostenuto (invented by the late John Seng) where you 
lay down a chord on a manual, kick and hold the Sostenuto lever, and the chord 
is held until the lever is released. This allows you to use the same hand to 
play single notes on the same manual.

I must admit that it’s all impressive to watch, but I find it not so much easy, 
but quite natural.

I do admire the guys who use break-in when conversing in Morse code, just like 
they were having an (almost) duplex conversation with each other. That’s clever 
and worth listening to.

I don’t consider myself anywhere near up there with the best, but what you 
describe is not unusual amongst Theatre Pipe organists. I’m not sure if it’s 
something we’re born with or whether it’s learned, mainly by practice.

The organist will often be playing 2 manuals (keyboards) at the same time, as 
well as running a bass line with one or both feet, alternating using the right 
foot from the bass pedals to one of several expression pedals (volume controls) 
or keeping their right foot against a sostenuto (special sustain) foot lever. 
All simultaneously with bridging one or both hands to select a note or two on 
one or two more manuals, and occasionally selecting some stops or pressing a 
thumb piston to select a combination of stops. Sometimes reading music from a 
score in front of of them *and* holding a conversation (during the easier 
parts).

For some reason this message was previously rejected for being too big!! It had 
a link with an example of a good friend of mine playing a Theatre Pipe Organ in 
a residence in Australia:
I’ll send that under a separate message.

 I'm one of those people with music constantly playing in my head, and 
I do occasionally end up hearing either two pieces or two different parts 
of the same piece running concurrently.  It's totally in the background -- 
the music just plays along pretty much no matter what I'm doing, like 
someone left a record player running.  I don't think the "frontal lobe" is 
involved at all except as an occasional listener.  Architecturally, I 
suspect that the parts of my brain that record and play back music tend to 
just idle in playback mode, and my conscious brain doesn't do much of 
anything to suppress them or block it out.

He copied code groups with split headphones, his left ear on a typewriter,
right ear written down, speaker in front of him he remembered until a pause
in one of the other messages and copied it down. He did have to be locked
up a few times per year.

Occasionally I stumble on something too incredible to not share, immediately, 
with everyone. In this case I'm inclined to not even apologize for using the 
bandwidth. At least not in advance.

Anyone intrigued by human perception of sound, especially musicians and 
ambidextrous CW ops, will find this fascinating, baffling, and perhaps 
enlightening in some way I can't predict:

2023-09-17 Thread John Gay

I owe my interest to an unknown person, likely a ham. When I was around 11 I 
found an Allied Radio and a Lafayette Radio catalog in an abandoned 
homesteaders cabin on the family ranch that some hunters had left behind after 
using it for shelter during the Montana deer hunting season. Old catalogs often 
served as TP in such circumstances. Until then I had no idea shortwave radio 
existed and being a little remote, we had just gotten REA. In went bingo cards 
for current catalogs.
 Not much later I’d taught myself to solder and built a Knightkit Star Roamer. 
Even joined the ARRL as an associate. But no one to work with me on the code; 
the one local ham I could find refused. 
Then as a GE freshman, the EE demo was really boring (the microchip revolution 
hadn’t hit the curriculum yet) so ME it was but engineering never the less. And 
more career changes ahead.

2023-09-17 Thread David Wilcox via Elecraft

Jerry,

One way to interest a son in radio and electronics expose him to others of his 
age that are interested and playing with it.  Possibly a call to a local scout 
master to see if he has any charges that have a similar interest.  

Sometimes it takes a few years. I exposed my secretary’s sons to electronics 
and SWLing when they were teenagers and 30 years later when they had their 
families and jobs stabilized they rediscovered ham radio and became licensed.

The best thing you are doing is something together with radio. My father was 
interested but never became licensed, BUT he took me to other hams homes and 
they showed me what they had and how it worked. And our family doctor was a ham 
and took me under tow. I became a family doctor AND a ham….. and Dad bought two 
Philmore radio kits and a one tube battery operated kit that I myself built.  A 
neighborhood kid was a ham and another ham lived across the street.  As I got 
older we made part 15 one transistor transmitters and sent CW around the 
neighborhood.  

It never stopped after that. Even in college and Med school there was always 
someone that had a ham rig in a closet somewhere and I borrowed it and got on 
the air.  On the air since 1960.

Sounds like one of their P-Box kits. When I was around the same age, my Father 
bought the 3-transistor regenerative Short-Wave Radio Kit. A listing of the 
P-Box kits can be found here: http://my.core.com/~sparktron/pbox.html

My Father was a Fireman, so there was no way he would trust me with a soldering 
iron at such a young age. Instead, he ended up building the kit himself while I 
watched with great interest.

He wound several coils so the receiver could receive several ham bands as he 
was trying to spark an interest in Amateur Radio, but I don't ever recall 
hearing any hams with the receiver, just the typical short-wave broadcasts of 
the time.

Several years later, he ended up taking the receiver away from me because the 
radiated broadband noise interfered with his Swan 500CX. :-)

It didn't matter much to me anyway as I never heard much with it. But it was 
every educational in the sense that the frequency range of the receiver was 
dictated by the size of the coil wound by the builder. Eventually he gave me 
his old Hammarlund HQ-140-X, so I hardly ever missed that old Radio Shack regen.

Interestingly enough, there's a modernized version of the receiver that employs 
silicon transistors (2N3904 and 2N3906s) instead of the original germanium 
jobs. Details can be found here: 
http://www.netzener.net/images/swradio/swradio.pdf

And that old Hammarlund lives on to this day after I "solid-stated it" not long 
after becoming a ham 40 years ago.

I was 8 years old. My dad had bought me a Radio Shack Science Fair
8-Note Electronic Organ kit for Christmas, along with a soldering iron.

That night I built the kit, finishing at something like 11 PM, which was
unheard of. I remember Dad looming over me in his green bathrobe,
smiling, saying it was OK to say up late just this once. He could see I
was in flow. Perhaps that validated his experiment.

The organ worked the first time I connected the 9 V battery. But I had
an ear for music, and after running through the notes, I could tell some
were mis-tuned.

Undaunted, I looked at the schematic and saw resistors. One per note.
That had to be the problem.

Thanks to Heathkit I had learned the color code that very morning. I
also had a box full of resistors I'd scavenged from old radios and TVs.
(Why?) I started sticking old resistors in parallel or series with the
shiny new ones until I had the notes all in tune, at least by ear.

At last I finished the job by bending the leads of the motley, oversized
resistors until they all fit in the bottom of the plastic perf-board
enclosure. Presentation was everything. (How did I know that?)

I proudly demonstrated the hacked organ for my parents, then for my
older sister, who was taking piano lessons.

At best I got my hair ruffled. But still: that was the day.

 Oh those days. I got my first crystal radio with the co,  stylus, and crystal 
back in 1966 but could only get one of the super giant AM radio stations, WKBW, 
 out of Buffalo NY spewing 50,000 watts on 1520 from the towers about 5 miles 
away. 
Having a problem with my KX3 in that with my KPA100 putting out 100W on a 
Buckmaster 10-80M  OCFD, 100foot center coax feedline. I can hear people but 
they can never hear me, even when they announce they are running barefoot on 
100W also, 20m during day and 40 and 80 at night. Gave up on the Elecraft 3.784 
Sunday 9:00 PM Net.  Last night, when I tried to transmit on JS8Call, I got a 
reply on my Windows 11  computer  with SignaLink that there was an "error with  
the audio input." The Notification Sound card output speakers , Input 
Microphone, and Output speakers on the JS8Call setup were reset to the previous 
USB Audio Codec.  It eliminated the error message but still no responses. 
Somehow the Codecs might have changed and I corrected the problem (I hope)? But 
strangely still no acknowledgement or reply from my heart beat inquiry and 
reply requests on JS8Call. This isn't a problem with the KX3 is it?
Also. will the KPA 100 ever suddenly switch on its own  from antenna 1 to 
antenna 2?  I now  keep a 100W dummy load on the unused one.
The KPA100 indicates 90-100 Watts on its lighted  linear meter during 
transmission. Is this reliable to confirm actual output/transmission to the 
antenna? Or should I join the club of those who get those watt meters to 
measure the actual power being sent out during transmission? Not for SWR, as I 
have a Rig Expert AA600 for that.
Got a notice from DxEngineering today that the 3000Watt capable Buckmaster 
10-80 M antenna is now back in stock for $311.00. I can't go vertical and not 
enough space for traditional dipole for 40 and 80 meters.  I've thought about 
just going ahead and getting a K4 and KPA1500 to end my frustration, even 
though I am essentially still a novice.  Sheer brute force to make things 
happen as with back in my college wrestling and football days.

I was 8 years old. My dad had bought me a Radio Shack Science Fair 
8-Note Electronic Organ kit for Christmas, along with a soldering iron.

That night I built the kit, finishing at something like 11 PM, which was 
unheard of. I remember Dad looming over me in his green bathrobe, 
smiling, saying it was OK to say up late just this once. He could see I 
was in flow. Perhaps that validated his experiment.

The organ worked the first time I connected the 9 V battery. But I had 
an ear for music, and after running through the notes, I could tell some 
were mis-tuned.

Undaunted, I looked at the schematic and saw resistors. One per note. 
That had to be the problem.

Thanks to Heathkit I had learned the color code that very morning. I 
also had a box full of resistors I'd scavenged from old radios and TVs. 
(Why?) I started sticking old resistors in parallel or series with the 
shiny new ones until I had the notes all in tune, at least by ear.

At last I finished the job by bending the leads of the motley, oversized 
resistors until they all fit in the bottom of the plastic perf-board 
enclosure. Presentation was everything. (How did I know that?)

I proudly demonstrated the hacked organ for my parents, then for my 
older sister, who was taking piano lessons.

At best I got my hair ruffled. But still: that was the day.

[Elecraft] [OT] Wayne Burdick wins 1st annual Kitchen Homebrew Challenge

2023-09-04 Thread Al Lorona

Wayne Burdick, N6KR, has taken the gold medal at the 1st annual Kitchen 
Homebrew Challenge held over the weekend.

The contest challenged engineers to construct a QRP transmitter using just 
three transistors and whatever else they could find in their kitchens. Although 
the designers were allotted 12 hours to complete the task, Burdick finished in 
half an hour.

"I used the remaining time to try and contact some stations with my transmitter 
and I came pretty close to Working All Continents, thanks to a fantastic and 
unexpected 10-meter opening!", he exclaimed.

Thirty other engineers from virtually every other manufacturer of amateur radio 
equipment entered the contest. A contestant from a large corporation in Japan 
known for its fine transceivers placed second when the judges deemed his 
transmitter closest to actually working, although it did not put out any power 
and kept blowing fuses.

Burdick needed only two of the 2N transistors he was given to achieve an 
output power of 1/4 Watt. "I know 2Ns like the back of my hand," he 
explained. "I felt sorry for one of the other guys, a younger engineer, who was 
begging the judges for a datasheet on that device. I guess he'd never used a 
small transistor with leads before and had no idea which were the base, 
emitter, and collector."

"For my capacitors, I used entire boxes of aluminum foil and parchment paper, 
and for the inductors, I used the heating element from my toaster," he said. 
"Once I had the oscillator done, it was all downhill from there."

"I thought of the heating coil idea, too, but I couldn't remember the formula 
for the inductance of a round inductor," said another contestant who wished to 
remain anonymous.

One of the other competitors implied that Burdick had an unfair advantage. 
"Isn't he that QRP backpacking guy? Here I was, trying to figure out how to 
steal the A-to-D converter in my coffee maker. I ripped apart the refrigerator 
motor for the wire and I tore my undercabinet lighting out so I could use the 
LEDs to display an FFT of my signal, but if I had known I could just make a 
simple oscillator and amplifier in an empty can of creamed corn with pill 
bottle caps for knobs, I might have finished in 30 minutes, too."

"I really made a mess of my kitchen and my wife is going to kill me," he 
lamented.

One of the major obstacles in this competition is how to come up with a supply 
of power. A player from the US attempted to use the power supply in his 
microwave oven. "Eeesh, you shouldn't use the 1200 Volt power supply in the 
microwave!", warned Mr. Burdick.

Mr. Burdick explained his own rationale for a source of power: "I was going to 
use an entire sack of potatoes and lemon juice to make a battery, but in the 
end I just collected batteries from my kitchen timer, cordless phone, and the 
emergency flashlight I keep in a drawer in case of power outages. I really had 
more than enough power. This was a relief since I had wanted to grill those 
potatoes for the Labor Day barbecue."

He summed up his experience by saying, "Simpler is better."

Burdick, a legend among low-power portable enthusiasts, has used homebrew 
equipment to make contacts while walking, swimming, and sleeping. He is 
co-founder of Elecraft LLC of Watsonville, CA.

Re: [Elecraft] [OT] A dumb question about lightning

2023-07-29 Thread David Woolley

> Lightning can’t tell whether something is grounded
> because the energy pulse hasn’t gotten that far yet.

[Full bottom quote follows reply.]

The path for lightning is determined before the main pulse of energy 
loss happens, and much of the communication involved in determining the 
path happens at the speed of light.

The actual lightning flash is a wave of energy conversion, from 
electrostatic, to heat (and then to sound and light).  The energy to 
drive it is already there.  It is isn't travelling down the growing 
bolt, but rather being taken from the volume surrounding it.

In fact, the main energy conversion doesn't happen until after the 
complete initial path has been established and actually propagates upwards.

Where it happens will be influenced by the distance between grounded 
conductors and the cloud, so, at the early stages, the presence of 
grounds (although not necessarily particularly good ones) will have an 
impact. However, it will also depend on the degree of corona discharge, 
which will depend on the sharpness of objects, as corona discharges 
will, effectively extend the effect of the ground into the air above the 
point.

The whole process will be complicated, and there will be a significant 
random element, but the presence of grounded conductors will have an 
effect in the very early stages.

Lightning can’t tell whether something is grounded because the energy pulse 
hasn’t gotten that far yet.

Lightning induces a current in every nearby conductor. When that pulse of 
current reaches a building or electronics, we want to provide a low impedance 
path to a safe sink (ground rods) and a high impedance path to the equipment (a 
choke). A lightning arrestor is a temporary low impedance path to ground for 
conductors that aren’t normally grounded.

The best high impedance path is disconnecting your equipment. That won’t stop a 
direct strike, because that will induce currents in the disconnected equipment. 
But it will help almost all the time.

Re: [Elecraft] [OT] A dumb question about lightning

2023-07-29 Thread Bill Gillenwater

I have the lightning tracker apps and monitor 3 local radar locations. 
Also, we keep and eye to the sky and our golden retrievers can sense 
lightning approaching.


My wife and dogs were in the yard under partly cloudy skies and little 
rumbles 15 to 20 miles away. A strike happened about 500 feet from the 
house. Pretty much out of "the blue". It was a big one.


Wife and puppies came running to the back door.

Be careful.

Hi Al,

The "Bible" on this subject that has been used for many years by the 
telecommunications industry is Motorola's "R56, Standards and Guidelines 
for Communications Sites":


https://www.blm.gov/sites/blm.gov/files/Lands_ROW_Motorola_R56_2005_manual.pdf

It's kind of complicated, but it's what you have to do if you really 
want to protect your site.  Of special interest are Chapter 4 "External 
Grounding (Earthing)", Chapter 5 "Internal Grounding (Earthing)", and 
Chapter 7 "Surge Protective Devices".

Protecting your equipment goes beyond a direct strike.  I had an element in
my K3 transmit final wiped out by a lightning strike a good distance away.
I wasn't on the air at the time but I remember the strike.  This was
through a pair of Alpha-Delta switches.

Sometimes I miss "the good old days" of vacuum tube rigs when I operated
during thunderstorms ;-)

Very good point.

I fhave a grounded entrance panel with appropriate suppressors for 
power, rotor, and antenna feeds. Everything metal, including my 
operating desk is connected to this panel and bonded together. I have 
installed a wifi-to-ethernet bridge on my desk to establish an air gap 
between the router and my computer and other equipment that require 
wired internet service.


The idea is to insure that if high voltages are induced on wires 
connected to my equipment, there won't be big potential DIFFERENCES 
between (for example) the computer and the radio.

In the home I bought here in W6, power, CATV, and telco terminate at the 
same point. That's a good thing. The only attempt at an earth electrode 
was about 35 ft of bare (#10?) copper (subsequently painted with the 
house) that wandered to the outlet for a garden hose, which was fed by 
PVC pipe. So the system had no ground.


They did slightly better in the mother-in-law garage apartment building 
that now houses my shack. The same bare copper, again painted, ran from 
that building's sub-panel, up into the attic, across to the other side 
of the building, where it snaked along framing and a window frame, where 
it finally was connected to a driven rod, the only one on the property.


There were other glaring wiring errors, including 120V outlets in a 
half-kitchen/laundry room fed between phase and green. There was a 
generator in a nice little doghouse, with manual transfer switches, but 
the generator was missing lots of parts, so it could not possibly have 
run. And a company got paid to inspect the place on my behalf (I lived 
in Chicago at the time). This turkey found a list of dumb stuff, like 
dimensions of exterior steps, but nary a word about electrical.

A very significant thing I remember that's new/significantly expanded in

non-ideally located. Other issues like that. A lot of little stuff, like 
responding to questions Ward had heard when he did talks to clubs and at

I suspect that is the rule rather than the exception.  I have seen 
several satellite and cable TV installations where the installer didn't 
bother to ground back to the service entrance and instead simply drove a 
short rod into the ground at a point closest to the cable gear.

Exactly what happened to me: the strike came in on the cable line, took out
the TV, the cable modem, the router, the computer hard-wired  to the router
(via ethernet), then to my poor K3 via the RS232 line.

Turned out when the cable was brought into the house many years ago the

I have the first edition of the ARRL book.  What is significant about the 
second edition that is different from the earlier edition?

The answer is, as KK9A said, to follow proper grounding and bonding to 
the letter. N0AX's ARRL Book on the topic, to which I contributed, is 
excellent. You want the Second Edition, published about a year ago. The 
book also references the slide deck for my tutorial talks. Don't let 
"audio" in the link fool you -- it's all about grounding and bonding in 
the shack for lightning protection and to minimize RFI.

This is the result of failure to follow proper grounding and bonding, 
and the failure of equipment mfrs to properly bond cable shields to the 
chassis at the point of entry. That failure to common to all ham mfrs, 
including Elecraft. This construction error was first addressed in 1994 
by a ham working in pro audio, Neil Muncy, ex-W3WJE (SK), and he called 
it "The Pin One Problem," because Pin 1 of the XLR connectors used to 
carry balanced audio is the shield contact. I addressed it beginning on 
page 5 of this RFI tutorial, which started out life in 2007.

k9yc.com/RFI-Ham.pdf

A major contributor to that lightning damage are the MOV-based surge 
protectors provide power to interconnected equipment. The MOVs short to 
the green wire; the IR drop in the green wire from that current spike 
raises the reference potential for equipment plugged into it, and the 
difference between that and the chassis of interconnected equipment 
that's grounded somewhere else fries the interconnected circuitry. We 
started seeing this in pro audio systems in the early '90s, with no 
antennas involved. The solution was elimination of those MOV protectors, 
replacing them with series-mode units that stored surge in a monster 
inductor, then discharged it slowly as a trickle after the strike had 
passed.

A colleague blew out the Ethernet ports of computers in his small design 
office from exactly this mechanism. Again, no antennas were involved.

Good suggestions, but there is never enough protection.  Best to have a 
“defense in depth” strategy.

Also good suggestions.  Additionally, go to Amazon and get a USB isolator.  
This breaks the ground connection between the computer and the radio.  Again, 
defense in depth.

Yes that is true too.  You can also get an ethernet lightning protector which 
has surge protectors in it (gas discharge tubes, not MOVs).  You need to have a 
ground return for it to be effective so back to the grounding that Jim is 
talking about.  

Oh, disconnect the radio.

Re: [Elecraft] [OT] A dumb question about lightning

2023-07-28 Thread Rick NK7I

We're in accord on static.  Like lightning, give it someplace to go 
OUTSIDE, not via the shack/structure.  Not just for noise but the 
voltages can be astoundingly high with enough amperage to cause harm.


[A local puts his feeds in a glass jar then is amused at the glow of 
discharge, contained.  But that is FAR from the only wire exposed.


These are complex topics that few can translate well to low dollars 
(hams) and better understanding.


It would have been fun to draw on that lunch crowd discussion.

The only true axiom is that if you don't have enough shunting, lightning 
will be happy to show you what you missed.  (Antenna didn't fall over?  
It's not big enough!).

Re: [Elecraft] [OT] A dumb question about lightning

2023-07-28 Thread Keith Trinity WE6R

Please, PLEASE disconnect your COMPUTER from your radio(s) if lightning 
is in the area!


Almost ALWAYS lightning damaged gear that comes in for repair, was hit 
_thru the comm port!_

(lightning hits Cable/DSL lines).

As far as repairs I see, it is not common for it to be damaged from 
lightning coming in the antenna.


It usually gets to your computer, then radio gear.

A direct hit however, and all bets are off. I've seen it come in/out via 
DC, keyer, PTT IN, even the ground lug, IE anything metal.

Re: [Elecraft] [OT] A dumb question about lightning

2023-07-28 Thread Walter Underwood

Lightning can’t tell whether something is grounded because the energy pulse 
hasn’t gotten that far yet.

Lightning induces a current in every nearby conductor. When that pulse of 
current reaches a building or electronics, we want to provide a low impedance 
path to a safe sink (ground rods) and a high impedance path to the equipment (a 
choke). A lightning arrestor is a temporary low impedance path to ground for 
conductors that aren’t normally grounded.

The best high impedance path is disconnecting your equipment. That won’t stop a 
direct strike, because that will induce currents in the disconnected equipment. 
But it will help almost all the time.

Re: [Elecraft] [OT] A dumb question about lightning

2023-07-28 Thread Rick NK7I


Not often (enough) does a ham have a 100'+ tower either.  

THE standard (of way so many to choose from) is from the cell phone 
industry (Motorola mostly).  It's insanely complex but if you're on a 
mountain top and need 100% reliability; ideal.  The costs, will be a 
second mortgage so some compromises will have to happen.


Here is a better link to the current (newest edition) of the ARRL book; 
at least a good starting point for a baseline understanding.  Direct 
hits, no matter what system/s used, will always show what you missed or 
didn't do enough to mitigate.


https://a.co/d/01vRC1W

Another aspect is static reduction.  That comes from wind, rain, dust, 
snow, anything that passes by the structure.  Shunt all to ground 
OUTside the building is the best approach.  (Base of the tower/mast and 
again at structure entry; make EVERYTHING at the same ground potential, 
inside and out.  When you take a hit, that potential rises, equally if 
all is done well; it's the difference in potential that harms.)

Subject: OT - FS: Begali cw paddle

Members on this list almost universally embrace CW, so
I thought I would offer this to the list before going to another
venue.  I sometimes can't respond immediately so I will make
a list of interested parties and get back to you as I can.

I have a new Begali "Pearl" key for sale.  Will send picture
and details on request.  It's too much key for my arthritis
which tends to send out characters before I can stop it .
I paid $338; sell for $300 plus postage.

It's everything people say that it is.  Same key as shown here:

See:  https://www.eham.net/reviews/view-product?id=8225

Cheers,

[Elecraft] (OT) WAE barely there

2022-08-13 Thread Robert Strickland via Elecraft

Usually, WAE has signals band edge to edge. Today, almost nothing. Any 
ideas what's happening? I checked the propagation sites and there's 
nothing about a major sun event. Puzzled.

[Elecraft] OT (Covid)

2022-07-22 Thread Wayne Burdick

In response to several private inquiries, and to render unnecessary any more:  
I’m off-line due to Covid. (No, I was not at the same party as Joe Biden :)

I’m going on my fourth day. It could’ve been worse. Streaming a lot of B-grade 
HBO to stay sane. 

I hope to be back in the saddle by Monday, answering emails and detonating 
fresh non sequiturs.

Re: [Elecraft] (OT) RufzXP sound problem - solved

2022-07-21 Thread Robert Strickland via Elecraft

Front panel sound now working... Hadn't tried it in a while, so it looks 
like some of the other adjustment I made brought it on line. Time to 
walk around the block...

Hello to all...

The problem that I initially described has found its origin in my lack 
of attention to details.


When connecting my headset to the sound card's external jacks [back 
plain of computer] I inserted the jack into the wrong terminal; when 
connected properly sound emerged. A second operator problem focused on 
the sound icon in the lower right of the screen. It allows individual 
adjustment of various sources of sound [eg, speakers, system sounds, 
microphone etc]. For reason I can't recall - or explain - I had the 
system sound slider all the way to the mute position. When set on max, 
the sound of the speaker tests at both the computer level and the Xonar 
audio card level emerged, clear and bright. I still cannot get the audio 
from the Xonar card to the front cabinet audio jacks. While the  line is 
connected, no sound emerges. More work to do.


So, the upshot of all this is operator problems in that I did not go 
over the many sound adjustment settings here-and-there well enough to 
prevent self-inflicted frustration. Computers users are a wide and 
diverse group, and I suppose the OEM's try to address the variety by 
making almost everything adjustable in hopes of being all things to all 
people. In this environment RTFM and open eyes [among other things] are 
indispensable.


Still don't know why I can't get front-panel sound...
