Re: [Elecraft] K3s - 80W on 160 - Resolved

[John Kaufmann]

I use a 6-foot run of 10 gauge cable between my power supply (the Astron
RS-35M) and my K3S.  With my Fluke DVM, I measured the voltage difference
between the power supply output terminals and the Power Pole terminals
inside the radio.  The difference is only .03 or .04 volts under maximum
current draw when transmitting at full power.  In other words, the voltage
drop across the entire length of the 10 gauge cable is negligible.  There is
no benefit to using a large gauge wire unless you are using a really long
(>> 6 feet) cable.

Hi Jim & the others who replied,

 

This is a follow-up for someone in the 

future who looks for the same solution. 

 

Yeah, the small amount of difference in 

the wattage is insignificant but 

considering all the radios I've owned, the 

low end of the bands were always the 

highest output. 10M was usually the lowest 

output & with the K3/K3s, 6M was always as 

good as the other bands watt wise and 160 

was full output. This not being the case, 

I was concerned.

 

I had done the calibration and raised the 

output to 87W but that was it. As was 

suggested, I raised the voltage from the 

PS to give me 13.8V on transmit which 

required 14.6V resting. I'm using the 

cable Elecraft supplies and I'm suspecting 

it could be just a tad lower gauge/thicker 

copper to reduce the resistance but on 

160M, I am now getting a 115W reading on 

the P3 and 113W on the LP-100A.

 

So the increased voltage was the 

difference in my case. A thicker wire 

would certainly require less voltage than 

14.6 and that's what I am going to look 

into. With the power Pole connector, I'll 

have to look a little deeper into what 

will work best. I have no crimping tool 

for Power Pole so that makes it more of a 

challenge.

 

Anyway, thanks Jim & all who suggested the 

higher voltage, it was the answer in this 

instance.

 

73,

 

Gary

[Elecraft] ERR KEY

[Howard Sherer]

I solved the problem. I had to force the control line DTR = Low in the
radio config menu of WSJT. I dontknow why but i tried many things andthis
works. So a note to others configuring WSJT.

Thanks everyone for the suggestions.

Unplug everything but power and antenna. Begin adding cables one at a time. 

What mode is in use on each of those bands?  Check VOX.

Re: [Elecraft] K3s - 80W on 160 - Resolved

[Ron D'Eau Claire]

FWIW, all of my 30A PP connectors are soldered, not crimped, as originally 
recommended by Wayne for those who choose not to spend the money on a 
purpose-built crimper for PowerPole terminals. I have not had any trouble since 
I started soldering PP connectors for my KPA100 fifteen years ago. I currently 
have about a dozen PP cables in the shack. 

To solder the terminals on the wires, I put the stripped wires in a vice, ends 
pointing upward. Slip the connectors over the exposed wire and align them to 
easily slide in to the housing later. I heat the terminal on the end and feed 
solder in through the small opening at the "top" of the terminal (when it is in 
the vice) so it flows down into the inside of the terminal and into the wire 
strands. That way there is no solder on the outside of the terminal or on the 
contact surface above where I add the solder. 

Solder on the outside of the terminal makes it hard to slide into the housing 
but it can be desoldered/filed down if needed. Solder on the mating terminal 
surface means it won't mate properly and the terminal needs to be replaced. PP 
connectors depend upon clean, flat mating surfaces for a proper, low-resistance 
contact. That is lost if a layer of solder is allowed to flow onto the terminal.

Properly done crimps that exclude all air and water vapor molecules from 
between the wire and terminal are as good as solder and they are a lot faster 
to make, especially with a little practice. That's why they are widely used in 
manufacturing where time is money. 

73, Ron AC7AC

Re: [Elecraft] K3s - 80W on 160 - Resolved

[Dave Fugleberg]

In the past I installed quite a few power poles with a crimper that was not
designed for it. Then a friend bought the purpose-built crimper, which I
borrowed several times. HUGE difference. Makes it almost fun!
My dear wife took note of this, and conspired with my friend to get one
under the tree last Christmas. Now we're all happy.
The purpose built crimper is much faster, but more importantly it makes
much better quality connections, and they always slip easily into the
plastic housing because the crimps are perfectly formed. Proper tools are
well worth the investment ( as is my dear wife).

Re: [Elecraft] Dead KAT500?

[W0MU Mike Fatchett]

Can you talk to the tuner with the usb cable?  You might just have 
scrambled the programming.

nothing more than a soldering iron, needle-nose pliers, and a good bench

don't crimp the smaller pins. I do tin the copper before soldering.


The 30A pins are the only ones that are difficult, and then only when 
fitting big wire into them. I use stranded cable for DC power wiring; 
for the few that are #8, I remove a few strands at the connector to make 
it fit. I then carefully re-twist it and tin it before crimping with the

Re: [Elecraft] KX3 - broadcast band interference ??

[yo8sep]

There is an AM broadcast station at 40miles from me,  but the signal I got
was on a foreign language,  maybe somewhere Middle East...
And it was all over the band,  even on upper bands,  15/10. Turning off Pre
or turning on RX SHIFT 8KHZ, seems to solve/hide the problem.  But that is
not really a solution,  especially when using NAP3 and CW skimmer.

Re: [Elecraft] K3s - 80W on 160 - Resolved

[Guy Olinger K2AV]

One does not need to jam too-large cable into the power pole connector. Do
the power pole normally with the #10 zip cord. Then two or three inches
away from the power pole, splice in two more parallel runs of the #10 zip
cord. Solder and tape these splices.

This will divide your voltage drop by three. 14.6 at PS can be 14.3 at K3,
better for TX IMD.

The IR loss is spread along the entire wire. A few inches of single #10 to
service the connector will not make any difference.

Another approach is to fasten down a length of #4 - 3 plus ground "Romex"
cable. You can get this stuff cut to exact length at the big box store. At
either end terminate with soldered splices to a few inches of #10 zip cord.
Black and green to black, red and white to red. That will allow you to put
PS anywhere you want. You do need a pretty permanent placement of equipment
for this.

73, Guy.

David,

I have two TLM 103 and they are a decent 
albeit not fantastic studio microphone. 
There is no way I would ever see it 
sensible to use them on Ham Radio as the 
off axis response they bring to the table 
will pick up every sound in your shack and 
that will pass right along into your 
transmission. 

If you ever had a fan running in your 
shack or an irate significant other 
anywhere in the house, everybody would 
know it. 

A poor choice for a communications rig.

Re: [Elecraft] K3s - 80W on 160 - Resolved

[Charlie T, K3ICH]

A possible solution is to use the heaviest wire you want from the power
supply to a few inches away from the radio with a very short pair of 12 ga.
wires from the APP to the heavy wire. 
 Shrink tubing can make an ugly connection look passable.  It's BEHIND the
radio anyway!

Subject: [Elecraft] K3s - 80W on 160 - Resolved

At my station I use a large 70 amp Astron power supply which sits on the
floor.  Several month ago, while trouble shooting another issue, I
discovered that the voltage drop in my 8' cables was significant. So rather

Re: [Elecraft] K3s - 80W on 160 - Resolved

[Ray Sills]

I’ll agree with Don:  If you are going to use Andersen Power Pole connectors, 
you have to commit to getting a proper (yes, a proper) crimper.  Yeah, they are 
not cheap, but the savings of time and frustration in assembling the connectors 
is worth the price.  And, like any good tool, it’ll have value in the second 
hand market, should you decide you don’t need it any more.  I’ll let my heirs 
dispose of my crimper.

[Elecraft] K3s - 80W on 160 - Resolved

[j...@kk9a.com]

At my station I use a large 70 amp Astron power supply which sits on the
floor.  Several month ago, while trouble shooting another issue, I
discovered that the voltage drop in my 8' cables was significant. So
rather than crank up the voltage I switched to 8ga and now at full
transmit wattage the K3S sees 13.5v. The tough part was squeezing 8ga wire
into a PowerPole connector that is made for 10ga max. For a shorter lead,
like I use when I travel to the Caribbean, 10ga has a minimal voltage
drop.

Hi Jim & the others who replied,

This is a follow-up for someone in the
future who looks for the same solution.

Yeah, the small amount of difference in
the wattage is insignificant but
considering all the radios I've owned, the
low end of the bands were always the
highest output. 10M was usually the lowest
output & with the K3/K3s, 6M was always as
good as the other bands watt wise and 160
was full output. This not being the case,
I was concerned.

I had done the calibration and raised the
output to 87W but that was it. As was
suggested, I raised the voltage from the
PS to give me 13.8V on transmit which
required 14.6V resting. I'm using the
cable Elecraft supplies and I'm suspecting
it could be just a tad lower gauge/thicker
copper to reduce the resistance but on
160M, I am now getting a 115W reading on
the P3 and 113W on the LP-100A.

So the increased voltage was the
difference in my case. A thicker wire
would certainly require less voltage than
14.6 and that's what I am going to look
into. With the power Pole connector, I'll
have to look a little deeper into what
will work best. I have no crimping tool
for Power Pole so that makes it more of a
challenge.

Anyway, thanks Jim & all who suggested the
higher voltage, it was the answer in this
instance.

73,

Gary

Re: [Elecraft] K1 Battery Power

[Don Wilhelm]

Ted,

The lower voltage of the battery pack is the reason.
If you are using NiMH batteries, the voltage is likely about 9.6 volts, 
and may be even lower during transmit.

Just added the battery option to a K1 and noticed something interesting.  When 
operating on battery power, no matter how the output power is set the actual 
power out is limited to about 2.0 watts.  It would make sense if this were a 
battery power conservation strategy; but I couldn’t find anything about it in 
either the battery option manual or the K1 manual.  Is this the designed 
behavior?

[Elecraft] KX3 - broadcast band interference ??

[yo8sep]

A few days ago I've noticed something strange at my KX3.
If was around dusk and I was on 20m band, USB trying to listen for a very
low signal station and got something that looks like an AM brodcasting , but
not in a language that I can understand.
The strange thing was that was heard even when tuning to different
frequencies.
PRE was on, antenna was yagi 3 elements on 20m, at 12m height.

I've made a short video, sorry for the poor quality. 
https://www.youtube.com/watch?v=CX7fr6Iwg-Q
  
 
If I changed the RX SHIFT settings to 8KHz, I still could see that signal on
panadapter (NAP3) but audio was shifted to 8kHz.

What could cause that problem/interference ? 

73,
Petronel
