[Elecraft] K3s Modules and Parts after COVID?

2020-08-01 Thread eric norris via Elecraft 
i got quite a scare tonight when I thought a W7 laptop's USB port gone rogue 
had taken out two KIO3Bs.  Does Elecraft plan on keeping enough modules and 
parts in stock after things return to "normal" to keep our K3s going for some 
reasonable period of time?  I'm experiencing a vague sense of dread.

[Elecraft] Elecraft CW Net Announcement

2020-08-01 Thread kevinr 

Good Evening,

    I spent the last few days listening on twenty and forty meters.  
The North American QSO Party is a good way to test my new antenna.  I 
have found the forty meter band picks up around 0030z.  The QSB flattens 
and the signals are easier to dig out. There is a noticeable difference 
in noise level between the inverted-V and the vertical.  After z I 
was able to copy MT, IL, MN, ID, KY, NY, NJ, NM, CT, SD, CO, FL, OR, AZ, 
OK, TX, KS, LA, NV, UT, CA, and wherever VK5MAV is located this week. 
Hopefully I can do as well tomorrow :)


  I will start the second net at 0030z since there was such a 
noticeable difference in propagation after 0015.  I will switch between 
the inverted-V and the vertical often.  As the days shorten I'll move 
the forty meter net back to z.  Until then I will see how we do at 
0030z instead.


   More berries are getting ripe.  I'm looking for a good spot for 
blackberries.  Maybe in the clear cut to the north.  Salmon berries were 
not too good this year.  Neither were the thimbleberries.  The wild 
straw berries were good though.  The fire danger is high right now 
because we have not had rain in over a week.  Looks like we may get some 
fog tomorrow night.  That will help the blackberries.


   There are two sunspots and the SFU is up to 72.  But the auroral 
oval is rather weak.  There was little QSB on anyone I heard on 20 or 40 
meters over the last few days.  Some was present as 40 woke up but then 
it disappeared.  Not much band noise either.  It did not sound like 
there were any thunderstorms.


Please join us on (or near):

14050 kHz at 2200z Sunday (3 PM PDT Sunday)
  7047 kHz at 0030z Monday (5:30 PM PDT Sunday)

   73,
  Kevin. KD5ONS

*THE BOOK:*
The Haggunennons of Vicissitus Three have the most impatient chromosomes 
of any life-forms in the galaxy. Where as most races are content to 
evolve slowly and carefully over thousands of generations - discarding a 
prehensile toe here, nervously hazarding another nostril there, the 
Haggunennons would do for Charles Darwin what a squadron of Arcturan 
Stunt-Apples would have done for Sir Isaac Newton. Their genetic 
structure, based on the quadruple-stellated octo-helix, is so 
chronically unstable, that far from passing their basic shape onto their 
children, they will quite frequently evolve several times over lunch. 
But they do this with such reckless abandon that if, sitting at table, 
they are unable to reach a coffee spoon, they are liable without a 
moments consideration to mutate into something with far longer arms - 
but which is probably quite incapable of drinking the coffee. This, not 
unnaturally, produces a terrible sense of personal insecurity and a 
jealous resentment of all stable life-forms, or “filthy rotten stinking 
samelings” as they call them. They justify this by claiming that as they 
have personally experienced what it is like to be virtually everybody 
else they can think of, they are in a very good position to appreciate 
all their worst points. This appreciation is usually military in nature 
and is carried out with unmitigated savagery from the gunrooms of their 
horribly beweaponed, chameleoid death flotilla. Experience has shown 
that the most effective way of dealing with any Haggunennon you may meet 
is to run away… terribly fast.

Same here. Most antennas that we can install are some form of 
compromise. Higher is better. One size fits all solutions generally 
don't perform as well as antennas optimized for a band or given 
application. Antenna tuners do NOT make an antenna work better, they 
simply allow the transmitter to put power into the feedline, and by 
optimizing the load that the transmitter sees, they reduce the 
distortion that the amplifier produces. Remember -- SWR is NOT a measure 
of antenna performance. Louder at the other guy's radio IS. Less RX 
noise IS.


What we all would do if we could is often very different from what we 
CAN do. What we would rig to operate from a park bench or on a 
mountaintop is usually very different from what we would do at home.

Re: [Elecraft] New antenna works!

2020-08-01 Thread kevinr 
My new antenna works well on 80, 40, 30, and 20 meters.  I have not 
tried the other bands.  While it was cut for 7100 kHz the design is good 
for other bands too, using the Elecraft tuner.  I am thankful my design 
does exactly what I wanted it to do within my design criteria.  It is 
quieter than my doublet and reaches parts of the US which the doublet 
does not.


Is there an ultimate antenna?  NO.  I never intended it to be used as a 
personal mobile antenna, nor as an antenna which works DC to daylight.  
I wanted an antenna with different propagation characteristics than my 
doublet for only 20 and 40 meters.


I live on a ridge exposed to high winds which occur regularly each 
winter.  I lose antennas almost every year.  Designing them with 14 ga. 
THHN wire helped a great deal.  Cheap.  Easy to find in most hardware 
stores.  Durable.  And easily repaired when the flying limbs break 
them.  I can't imagine the replacement costs for a Yagi-Uda antenna.  I 
doubt they would last two years with the flying branches I experience.


Antenna design is part of the fun of amateur radio.  The other part is 
enjoying what you can afford, mount, and use.  Your design criteria will 
not be the same as mine.  Thus your solution will be different.

your signal most of them will burn up first. TLW, the free app that

connectors, wattmeters, filters, switches, elbows, lightning arrestors, baluns, 
autotuners, , , that many folks use. Everything has loss, but in effect 
we trade that loss for some other valuable function... like being able to QSY anwhere, 
easily. To give you a data point, on 12 meters my station has a max loss (from 
transmitter to the antenna feedpoint) of 1.6 dB. I'll put that worst-case number up 
against anybody's long run of coax through all the other junk from their transmitter to 
their antenna.

Folks, you should not feel inferior for having chosen to operate on many bands 
with an antenna tuner. I think the case could be made that the *resonant* 
antenna is the compromise, giving up all band operation for some other desired 
function. And sadly, sometimes that compromise is made just so they can say 
that they're not using a tuner!

Multi-band antennas are fine as long as you recognize that they are a
compromise.

Re: [Elecraft] K2 crystal filter upgrade

2020-08-01 Thread Don Wilhelm 

Mike,

Yes, the new crystals will improve the filtering in the K2 - there may 
be a few exceptions, but that is not the rule.


The filter response will be smoother.
Your K2 RF Board also likely has the older crystals, so change them as 
well.  Get the matched set of 14 crystals.

performance?

Thanks for any feedback.

Re: [Elecraft] New antenna works!

2020-08-01 Thread Al Lorona 
I'm glad Dave added that to the end of his message, because each time the topic 
of multiband antennas comes up, we are told, "That's too lofty a goal for one 
antenna. Just put up a resonant antenna and all your troubles will be gone." 
All except for the problem of operating on all bands without having to put up 9 
resonant HF antennas, that is. I think we do a disservice to the hundreds of 
hams reading this by discouraging them from multiband operation just because we 
deem it too "noisy" or "lossy" or "inconvenient" or whatever.

If a man or woman, knowing full well the consequences of his or her actions, 
chooses to utilize a single, horizontal antenna of no particular length, 
ultra-low-loss feedline long enough to reach the shack, and a low-loss homebrew 
or commercial manual antenna tuner to operate on all bands, then who are we to 
tell him or her that they shouldn't? To do so has always struck me as 
presumptuous.

Incidentally, can we do two things? Can we all get over the gross assumption 
that we continue to make, that when someone mentions feeding an antenna with 
"balanced line" that must mean Wireman #553? There are better alternatives. If 
our beef is with Wireman #553, then let's be on with it without condemning 
*all* forms of balanced line.

Secondly, antenna tuners are not necessarily lossier than the aggregate of 
cables, connectors, wattmeters, filters, switches, elbows, lightning arrestors, 
baluns, autotuners, , , that many folks use. Everything has loss, but in 
effect we trade that loss for some other valuable function... like being able 
to QSY anwhere, easily. To give you a data point, on 12 meters my station has a 
max loss (from transmitter to the antenna feedpoint) of 1.6 dB. I'll put that

[Elecraft] K4 remote

The doc for the K4 talks about K4:K4 remote or from computers.  Right now I and 
others are using RemoteRig boxes to have K3S:K3S.  Is there a means to do a 
K4:K3(s) using RemoteRig? Or is a K4 required on both ends?  Might you flesh 
out the K4 remote configuration capabilities a bit for us?  Tnx.

Re: [Elecraft] KIOB3B for K3

2020-08-01 Thread David Ferrington, M0XDF 
Bill, I did the same but not fitted yet - would be interested to know your 
thoughts on fitting. i.e. did you do a F/W upgrade first etc (mines a bit old).

Re: [Elecraft] New antenna works!

2020-08-01 Thread CUTTER DAVID via Elecraft 
Dave and Jim

Our friend made strong mention of SOTA and the KX series of portable rigs and 
those users often require a multi-band antenna for simplicity and to keep the 
weight down.  Our friend's 40m vertical is also being used on 20m, so, it's 
reasonable to assume he desires multi-band performance, perhaps even more 
bands.  In portable situations the feeder is often short and sometimes 
non-existent so there is little or no transformation.  Elecraft promote their 
rigs to be used with non-resonant antennas: why strive for such a wide range 
matching unit if not?  Eric has told us many times that he is happy with odd 
lengths of wire thrown up a tree and another piece thrown on the ground as a 
counterpoise, ie multi-band, non-resonant antenna.  In these situations lobes 
and radiation angles are less important than just getting out.
