Re: [Elecraft] Beware of junk mail: "four pictures to you from Elecraft List"

[Bill Lederer]

If you use google mail/gmail, there is a feature called "Show Original"
that you see if you click the three dots in the upper right corner of the
email.

You can also report phishing from that drop-down.

I can imagine it would be different on RTTY, but our CW operation from
Vanuatu from YJ0V/YJ0PD was quite instructive.  One approach to decoding
the signals, all almost on the same frequency, and peaking at S2, was to
find the edge of the pile and listen to the one you could decode.  Many of
the callers were quite savvy and would then jump to that frequency, making
that the new "center". And the process would repeat.

The thing about the rhythm (I mean this is a little different way than you
are using it here--I mean the timing) is that it is a very important
principle to use if many stations are calling you. Most of the crowd will
get the pattern and follow it. Without the pattern, things can quickly turn
into pandemonium. With the pattern, stations that don't hear you very well
can catch on and only transmit in the "window".  There were always a few
that wouldn't follow, but the significant majority would.

So the DX station has a lot of influence on the discipline of the pile.
DIfferent stations would follow it to different degrees. JA was relatively
loud compared to US and EU, so if we were trying to dig a US station out,
one simple call to "us only" would clear up a temporary lull. No JA station
would call then--none. So then we would do that for one or two QSOs and
then open it back up to all callers. There was one EU country that I won't
name that refused to follow any of our directions.

One first we did was to provide in near real-time (within a minute or two)
an acknowledgement on our web site that we had worked you. Our club
"Prairie DX" was the first to do this. VK0IR did something similar prior to
that, but it was not near real time. We first did it in the Saint Pierre
and Miquelon Dxpedeition. This saved the kind of heartache that was the
case with 3Y0J where there were pirates and you didn't know if you worked
them or not until they were done.

And yes--you don't need a second receiver to work split. But it is fun to
have a different antenna feeding into each ear, such as your transmitting
antenna in one ear, and an RBOG in the other. Fascinating stereo effect.

Sorry for this being quite off topic. While one of the radios we had was an
FT 1000 MP Mark V, in retrospect it would have been nice to have several
K3S.

[Elecraft] K3S, N1MM and DTR/RTS to send CW

[Bill Lederer]

Team:

Our club has used N1MM for past field days with K3s using DTR RTS settings
in the radio and in N1MM to send CW.

I am trying this with my K3S with a laptop from Field Day, and get errors
whenever i set PTT-KEY to anything but the default. Additionally, some of
these cause steady key down or steady PTT conditions.

I'm connecting (as we did last year) via USB cable.  N1MM is reading the
radio ok--it shows the frequency changing when I move the frequency knob on
the radio.

Is the K3S different in this regard?

[Elecraft] Firmware download

[Bill Lederer]

I'm using the "Elecraft K3 Utility v1.19.9.6".

Clicking on the "Copy New FIles from Elecraft" checks which files I have,
and says "One or more required files from Elecraft Server."

I visited the Elecraft page listing the firmware, and my directory has all
that are shown on the web.

Is there some step that I am missing?

Absolutely agree.

I tested them before they were installed.  One positive hint was that they
have a FCC id number.

Re: [Elecraft] Fluorescent RFI solved

I have about six of these, two in the garage, and four in the basement next
to the shack. They emit no detectable RF noise.

Oh, and they are the color-changing variety, but i haven't done the color

Re: [Elecraft] QRP and contesting

That is pretty impressive.

When I was first a ham, one of the locals was W7QYA, Flo, a school teacher
not far away. I had managed to crank my speed up to 40 (with some struggle)
but she said that was painfully slow for her. Her nominal speed was 65
wpm.  I have yet to get much above 40.

Re: [Elecraft] AX-1 -- with and without counterpoise

I do a similar evaluation of antenna combinations (random wire with/without

[Elecraft] Speaking of Counterpoise

[Bill Lederer]

Folks:

I think there was a little note in the KX2 bundle about the type of wire
that is used in the counterpoise wires shipped with the KX2.  However, I am
unable to locate it.

I think it had "slick" in its name.

[Elecraft] So today i learned about BNC-BP and red/black terminals

[Bill Lederer]

Team:

I have been using a wire out the window from my upstairs office for an
antenna for my kx3. The wire goes to a tree about 30 feet away, so it is
essentially a random wire.  I have an additional wire that goes to a ground
rod one floor below.

In doing some experiments with RBN and this combination with 5 watts, I was
confused about why connecting the wire to the tree to ground through the
BNC-BP and the ground wire to the hot side of the BNC-BP gave better
results.

Finally, I measured which was which, and discovered that the black plastic
nut on this connector is actually connected to the center pin of the BNC,
with the red being ground. This was certainly contrary to my expectations.

I also have a kx2 and got one of these connectors along with that kit. And
sure enough, it had the same convention--black is the center pin, red is
ground.

This is contrary enough to my intuition that I reversed the nuts, so now
that the red indicates the center pin.

Is this a convention that black is hot and red is ground with these?

Thanks,
w8lvn

Re: [Elecraft] KX3 and Heatsink

Thanks all for the replies.

I'll probably stick with the factory installed one, as I do have the 100
watt amp which I'll use if I need higher power.

[Elecraft] KX3 and Heatsink

Folks:

I have a recently-purchased KX3 that includes the Elecraft-supplied heat
sink.

Is there any opinion of this does an adequate job compared to the ProAudio
one?

Re: [Elecraft] Legal Limit With FT8

This is what I do when running SO2R on FT8/FT4. I ensure that both are on

This insures no intertransmitter interference.

Re: [Elecraft] HD8R

[Bill Lederer]

Drew:

Cool collection of keys!

Congrats.

I was quite lucky to work them with my KX2 and a random wire out the window
from my office during work hours. (Big Iron, rather Silicon is in the
basement shack.)  I would hit the MSG then PRE to send my call. After
several hours of trying I was able to snag them. This was on 15 meters.

And from what I can tell, they had a super operation. Good ops, and they
appeared to hear quite well.

Re: [Elecraft] HD8R

Worked them the other day with my Kx2 but to a random wire.  Did it while

Plus it seems that they have very good operation.

Re: [Elecraft] Problem Tuning K3

[Bill Lederer]

Not Dick Tracy here, nor am I K9YC.

I had very good results running mobile with 100 watts and a hustler on the
roof of my Suburban. I also have fun with my kx2 and a random wire 15 feet
high out the window to a tree.

Your notes about the success of various real-world examples leaves out what
the comparison would be with a true dipole. For a true test, you would need
to do a head-to-head comparison of the two antennas. K3LR used to do this
at Dayton.  Proof is not how many OCF antennas fly above roofs, but how do
they compare to a similarly situated dipole.

A true test of equipment and antennas is how well they do in a contest.
With these OCF antennas, can you work 100 countries in a weekend on
multiple bands? Can you get to 300 countries in DXCC? Much less likely than
dipoles, properly built verticals or beams.

Can you have fun with OCF or other compromise antennas? Yes. But other
antennas are likely to do better.

Re: [Elecraft] Notable SSB QSO (HD8R)

By far it is the most fun per watt of any radio that I have ever owned.

I worked HD8R on 15 with 10 watts to a random wire.

[Elecraft] KX2 temperature

[Bill Lederer]

Team:

I discovered that the KX2 will trip out if its temperature gets too high.
Clearly, this is a good thing. I am considering getting the heat sinks for
the side. I now run with the temperature displayed.

My question in relation to this is: is there a fixed temperature that it
will trip out at? Alternatively, what is a  good threshold to observe to
avoid over-temperature  operation? The manual does not seem to be very
specific.

Thanks for a great radio (I have it in my office  upstairs with a wire to a
tree, and get on the air between meetings.) and for a great forum.

Re: [Elecraft] [OT] Ham Radio near high voltage power lines?

[Bill Lederer]

Here is a shot of my QTH back when I lived in Lake Forest:
https://www.google.com/maps/place/110+W+Old+Elm+Rd,+Lake+Forest,+IL+60045/@42.2181966,-87.8488795,338m/data=!3m1!1e3!4m5!3m4!1s0x880feaa987ea773f:0x8c16ace134e48f27!8m2!3d42.2183734!4d-87.849711

You can see the shadows of the huge HV power lines on the right side, just
short of Skokie Valley Road.

I had three monobanders at 50 feet and did not notice any noise.

Here is a shot of how big those lines are:

Re: [Elecraft] OT: High school drafting class,

[Bill Lederer]

My cursive died when I got to engineering school, and now even my printing
is not improving, to some extent to writing mostly with keyboard.

No drafting in High School, but my first Freshman course in the EE program
was pretty awesome. Professor Kliphardt taught us mechanical drawing, where
we learned to make 3-d drawings of various objects, solving problems like a
pipe coming through a wall and determining if it intersected a desk or the
person sitting there. You would solve this by rotating the drawing, using
projection to spot the path. He would do all these drawings with a chalk
and a piece of string. Was amazing to watch.

Was a very fun course. (The next quarter was intro to computer programming,
and that derailed me for the next several decades)

Re: [Elecraft] KX2 Questions

[Bill Lederer]

I have the kx2 and absolutely love it.

1.  What is the approximate current draw for the KX2 on transmit at 5 watts
CW?2.

At 10 watts, it is 1.87 amps. At 5 watts, it is 1.49 amps. Receive is about
0.15 amps.



2. What is the narrowest receiver filter width on CW?

It goes down to 0.05 kHz.

[Elecraft] KX2 and WKmini

[Bill Lederer]

Folks:

I recently bought a WKmini to use for portable operation. In reading the
documentation, it turns out that the cable supplied that goes from the OUT
port of the WKmini to the key jack on the KX2 keys the tip with the code,
but use the ring to do a PTT function. I'm fine with QSL on the KX2, so I
don't need this. And in fact, the KX2 will key when either the ti or ring
is  engaged by the WKmini.

Experimenting with the MacWinKeyer.app, there is a selection to turn off
the PTT function, and that works nicely.  I had hoped that exting the
program would leave that setting in the "no PTT" mode, but it is not to be.

So is there a  way that the KX2 can be convinced to only pay attention to
the tip when the mode is set to "Hand" and not the ring?

Thanks,
w8lvn

[Elecraft] KX2 Power supply

[Bill Lederer]

Friends:

I like to use my KX2 in my office with a wire out the window to a tree,
largely for listening, e.g. to ARRL code practice. I normally use the
internal battery and charge it up ever couple of weeks.

I am wondering if KX2 owners have used a DC supply to power this--short of
getting an Astron or equivalent--one that is just the right size that can
power a 12-watt radio.

Thanks.

When you are using the amp, do you do break-in there as well?

Re: [Elecraft] Questions about KX2 possible purchase

[Bill Lederer]

I bought the KX2 with all options save the Key paddle. I also got the
antenna and the bag. This included two lengths of ground wire.

Haven’t done sota or much remote yet. I would take handfuls of various wire
lengths in addition to the ground wire.

I did operate it from the Titan missile museum with their 80 foot Discone.

High recommend this rig

Re: [Elecraft] RFI issues

[Bill Lederer]

House we just moved into, we did new under-the-counter lighting.  Once I
got the ham shack started, I saw s9 noise on 160 and 80. Turn them off, and
it becomes quiet.

Other led panel lights produce no noise whatsoever.

But now that that is identified, I will be tracking down some other noise,
likely in the neighborhood.
