[Elecraft] Elecraft CW Net Announcement

[kev...@coho.net]

Good Morning,
Our normal rain has turned to snow; luckily that also means the sun 
is back.  Other than for the rare glimpse this is the first I have seen 
of the sun since mid-November.  Currently the trees are covered with 
hoar frost awaiting the first touch of sunlight.
Conditions have been fair to OK this week so chances are you can 
hear my signal.  I am looking forward to the dry season when I can 
perform an antenna rejuvenation project.  Or collect all the odds and 
ends from many previous antennas and build the next one.  I'll need to 
work on my archery skills so I can hit the higher limbs necessary for my 
inverted-V.


Please join us on:

14050 kHz at 2300z Sunday (3 PM PST Sunday)
7045 kHz at 0200z Monday (6 PM PST Sunday)

   73,
   Kevin.  KD5ONS

[Elecraft] I had a KX4 Vision

[Dan Baker]

While working the 160 meter contest of which I enjoyed immensely. I had a
vision of a KX4. It was a screen with a home button. It ran multiple apps
and had the option of a second and third screen.

I also saw a black box version for a bring your own tablet solution.

Then I noticed I must have nodded off for a second.

But I believe Eric and Wayne can build you just about anything you are

willing to pay for.

[Elecraft] hum in K3 when above 30W

[NK6A-Don Minkoff]

I have a K3, Ser no 4569, that all of a sudden is giving me a 
transformer like hum when I transmit above 30 W.  Does something need 
tightening all of a sudden? This is a very annoying. Anyone else 
experience this and find a fix?

Re: [Elecraft] hum in K3 when above 30W

[Don Wilhelm]

Have you considered that it could be coming from your power supply? Try 
another power supply or run it from a large battery as a test.

[Elecraft] Lack of low freq response K3 ssb rx audio

[Barry N1EU]

I made some spectrum curves of the 4KHz BW rx passband with FC of 1.00,
1.50 and 2.00 to illustrate what I'm talking about.  This list bounces
image attachments so if you're interested, please look at them here:
http://k3s.wikidot.com/

The posted curves have been verified on another K3 and RX EQ is flat.

My original question was:  Why does the audio passband dramatically roll
off in the lower frequencies as my Shift/FC goes above 1.40Khz?

I think the spectrum curves partly answer the question.  They reveal a  a
maximum passband width of 3300Hz (-3dB points) in SSB even though BW is
4000Hz,  within a 6KHz wide roofing filter.  I don't understand the
discrepancy between selected bandwidth and what the K3/K3s is providing.

For comparison, a passband curve in AM mode is also shown and it reveals
extended flat response from below 50hz to almost 4000Hz.

I use Noctua fans for most everything. Have used them for years and haven't had 
any failures. I use them for all systems I build for clients and myself. They 
have several varieties for each size and the ones with rubber mounts are 
generally the most quiet.  Also have a choice of 3 and 4 pin plugs.

While most of their fans come with rubber mounting hardware, the ones I suggest 
have rubber inserts surrounding the bolt/screw holes‎.

Noctua is an Austrian company but fans are built in the orient. Top quality 
with 'SSO2' bearings. 

Both Amazon and Newegg have them and the prices generally run from about 
$15-18. Just make sure the specs (CFM)  match (or are better).

While I haven't measured them on mine, they look like 80mm.

Subject: [Elecraft] Quiet fans for K3

What are the current options for quiet fans for the K3? My original fans 
are pretty quiet but at this time of the year when the windows are 
closed and the ambient noise level is nil, the fan noise really starts 
to bug me. It's the very slight rattle they make when they start winding 
up.. (In the din of summertime, can't hear myself think, let alone fan 
noise.)

Sources? Prices?

Are the newer Elecraft fans quiet? My PA is only a couple of years old 
so the fans are pretty recent model.

I would buy one right now.

Re: [Elecraft] Love me K3 line

[Vic Rosenthal 4X6GP/K2VCO]

Once you have a reasonably loud signal and an antenna that allows you to 
hear the DX, the most important attribute of a DX-oriented station is 
agility. You can tune the bands and when you hear something you need to 
be able to jump on it instantly. Get him before he's spotted and the 
pileup builds up. That's where the no-warmup, no-tuning KPA500 helps.


Once the pileup is going, you need to find the stations the DX is 
working and figure out the operator's pattern. That's where the 
subreceiver and the P3 are useful.

Re: [Elecraft] Love me K3 line

[Gary]

I don't get it to be honest.
Why is there an obsession with 1500w?
Seriously, I do not believe I have 'missed' working a popular DX party because 
I DON'T  have 1500w to play with.
I do know that I can be heard amongst the cacophony of noise in a pileup. Does 
that make me work harder?sure it does, but I still get the same thrill of 
the contact and I don't have as much qrm issues in VK either..it's all 
relative?
I like my no nonsense kpa500, no more tuning up issues, no expensive amp ir 
tubes, instant on etc 
Yep I have had a big tube amp in the past and I genuinely don't miss it, really.
So yes I do enjoy my k-line and I have Wayne and Eric to thank for letting me 
enjoy my wirelessgrin

The question is why you worked 15 ATNO's.   It may be totally unrelated 
to the K LINE.

One thing for sure you can't defeat the laws of physics.  1500 W -> 500 
Watts is a 4.5 dB loss.  That is huge in a pileup.  So tell me how the K 
LINE makes up for that loss and then some.

True, and I notice it here when I get beat by other W6s with similar stations 
other than the amp.  I live with it given the incredible integration of the 
KPA500: I have the amps in a closet and never touch them. They just work.

My hope is that Elecraft becomes a giant corporation with enough R capital to 
bring back the KPA1500! Come on guys, buy more stuff!!

Re: [Elecraft] Love me K3 line

[brian]

The question is why you worked 15 ATNO's.   It may be totally unrelated 
to the K LINE.


One thing for sure you can't defeat the laws of physics.  1500 W -> 500 
Watts is a 4.5 dB loss.  That is huge in a pileup.  So tell me how the K 
LINE makes up for that loss and then some.

Re: [Elecraft] Unpacking the K1 package contents

Perhaps it should be called a thermal conductor and electrical insulator but
then some people always complain even if hung with a new rope.

Hello Mark: 

The "thermal insulator" is a thin flexible rectangular bit about 1/2" by
3/4" in size that has a hole near one end and is self-stick, so it is
supplied on a bit of backing paper you peel it off of when you install it on
the power transistor. It may be in one of the little brown envelopes. There
is a photograph of it still mounted on its backing paper in the parts list. 

The Acrylic Bezel is the plastic cover over the LCD on the front panel. Look
at the drawing of the K1 on the front cover of your manual and you'll see a
rectangle depicting the cover with a screw at each corner covering the LCD
itself and the words "Elecraft" and "K1 Transceiver". It should be in one of
the brown envelopes in the kit.

[Elecraft] K2, squelch lock in

[Hans Bonnesen]

Starting a remote fling I’m using my K2 coupled via an Akoya laptop PC to:  Ham 
Radio Deluxe, Teamviewer and Skype.
I’m puzzled by the squelch setting on Ham Radio Deluxe which for unknown 
reasons tend to slide up to the 80 digit whenever closing down the system.
This extremely annoying when I work the K2 in a normal detached mode, where I 
find the K2 squelched down unless signals are very strong.
Is there a push-button way to delete the squelched condition on the K2 itself.?

[Elecraft] RF Exposure Levels

[Dauer, Edward]

Thanks, Bob.  I received a couple of other private replies raising the 
same question, about RF exposure using an amp and an indoor antenna.  
There is an RF exposure calculator available on the ARRL’s site, or 
directly at http://hintlink.com/power_density.htm.  My configuration at 
100 watts is only about 1/4 of the safe maximum.  Nonetheless your caution 
is appreciated and well advised - hence my posting the calculator site 
here for any others who might be sitting close to their antennas.

Ted, KN1CBR

Candidly, I would be more concerned about exceeding the RF Exposure 
limits with this arrangement.  Perhaps the "Tuner issue" is an 
indication of such.  From your description, at 100 watts you will likely 
be way outside of the FCC limits of safe RF Exposure.

Now with that said, the amount of RF at the TUNE level is not such to 
confuse the tuner.  However at 40+ watts the RF back into the system is 
more than the system can accurately handle.  A bunch of #31 beads or #73 
beads, where "bunch" = 50 pcs or more, on the feed line at the antenna 
feed point and again a bunch at the radio. This may help the radio and 
antenna problem associated with the auto tune routine.  You may find the 
same treatment required on the DC power cable at the radio.

Re: [Elecraft] WTB KX3

[Don Wilhelm]

Tomy,

The options you select for the KX3 will mostly be determined by your 
operating aspirations and your antenna system.
If you do not have resonant antennas for all bands, then you will want 
the KXAT3.
If you envision portable operation working on batteries, you may want 
the internal battery charger.
If you are operating in a DX pileup or contesting situation, you may 
want to add the KXFIL3 roofing filters.

If you want 2 meter capability, then add the 2 meter option.

In other words, give thought to your antennas and the operation that you 
anticipate with your KX3 and you will be able to configure it to best 
suit your needs.


73,
Don W3FPR

[Elecraft] Lack of low freq response K3 ssb rx audio

[Barry N1EU]

I'm pulling my hair out on this one, but let me keep it real simple.  This
is on a K3s and all hardware/firmware is latest/greatest.

Filter: 6KHz
Mode: USB
BW: 4.00KHz

My question is this:

*Why does the audio passband dramatically roll off in the lower frequencies
as my Shift/FC goes above 1.40Khz?  *


I would think that there wouldn't be any bass rolloff until FC was above
2.0KHz (i.e., half of 4KHz BW).  Instead, what I'm observing is:
- with FC of 1.6KHz, I see  -8dB at 100Hz
- with FC of 1.8KHz, I see -15dB at 100Hz

I'm using Line Out to soundcard and Visual Analyser 2014 software.  It
mirrors what I hear in my headphones.

73, Barry N1EU
