[Elecraft] K1 Battery Power

[Dauer, Edward]

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?

Re: [Elecraft] KIO2 troubles

[Nate Lewis]

after many years away, hello again -


I'm trying to get my K2 back online, with a KIO2 in it.  (I have a 
KAT100-2+K2/100 in a separate box, disconnected for now.)  I'm pretty sure all 
this worked when I put it away - ten years ago maybe.


I'm using PuTTY in Windows (with a brand new untried USB/RS232 adapter), set 
4800/8/N/2 with no control.  From the "port on" menu, the display button gets 
me a "FA;" in putty as expected.


However, I can't get communication going the other way.  I've doublechecked the 
cable pinouts and.  Digging in, I see signal coming in to KIO2 U1 pin 6 
(MAX1406's R3IN), but always 1.4VDC at R3OUT. :(


Disconnecting RS-232 and measuring: at the 1406, Vdd is ~13V, Vss is -3.8V 
(hmm...valid, but unexpected), and Vcc is 1.2V (!), matching the output from 
the 7805 (!).


I lifted the output pin from the 7805, and it shows 5V again, so...something 
else on the KIO2 is pulling it down, but what?  I don't understand the 
derivation of Vss or what's inside the 1406, so I don't know where to go from 
here.


Advice?  Thanks!

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

[Don Wilhelm]

All the APP connector blades (inserts) that I have seen which will take 
#10 or larger wire (30 amp) must be crimped.  They have "fingers" that 
must be bent over the wire.  Use a proper crimper for PowerPoles, 
substitutes will make a mess of the job and mess up the contacts.


If you wish to use a bit of solder after crimping, that should be 
possible, but first crimp with a proper crimping tool.


The 20 amp contact blades can be soldered, but the largest wire they 
will accept is #12.


An alternative for less voltage drop is to shorten the cable rather than 
increasing the wire gauge.

Hi Jim & the others who replied,

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.

With the ATU in or out it gives 81W out on 160, SWR is 1.28

All other bands except 6M give around 98W, 6M gives 87W

Any ideas what might be causing the lower output on 160?


81W is 0.9 dB less than 100W; 87W is 0.6 dB less than 100W.  On 6M,
it's probably a simple matter of efficiency -- power amps are slightly
less efficient on 6M than on the lower bands.

And there may be a power calibration issue. There's a procedure in the
manual for doing that.

Or even error in the power measurement itself. Few power meters are
specified for better than 5%. Bird wattmeters are specified as 5% of
full scale, and a condition of that is that the slug is in
calibration. If, for example, you're using a 250W slug, accuracy is
+/- 12.5W. I use an N8LP LP100A, which specifies 5% at any power level
from 1W, and quotes 3% typical. 5% is 0.22 dB.  3% is 0.13 dB.

Low DC voltage can also be an issue, either due to the power supply
itself or IR loss in the power cable (or even the connector(s). Use
the built-in metering function to check DC voltage with just the RX
running and keydown. Short, fat copper is your friend. :)

[Elecraft] connecting K3 (or other radio) to Expert 1.3K-FA

[Jim Spears]

The easiest way is to buy the cable set from Dan Tassel at Expert Linears.
Or clone it.  I have the cable set and it works FB with the K3 and a
different set for the KX3.

 

For Jim, K9YC, your statement about the 1K-FA and its internal tuner is
correct for the 1K-A, the tuner is in line at all times.  The 1.3K-FA can be
ordered with or without the internal tuner and can be taken offline for any
or all antennas.  I have the tuner disabled for bands covered by my SteppIR
or resonant antennas and enabled (with training) for those ill-behaved
antennas.

Re: [Elecraft] K3 - Audio Drops

[hb9brj]

While I never suffered from the "audio drop" issue after shutting down
Log4OM, it seems that the new WSJT-X 1.7.0 produces the same effect when it
is terminated. My K3 goes absolutely silent. Touching the WIDTH control
brings audio back. WSJT-X is widely used, so hopefully there is a chance to
find the root cause.

Re: [Elecraft] [KX3] Changes to newer models?

[Don Wilhelm]

Rick,

Go to the Elecraft website and open the Mods and Notes page.
Then look at the KX3 Application Notes and also at the KX3 Mods.
Decide which ones you want to install or have installed.

Re: [Elecraft] Connecting the K3 to an expert amps 1.3K-FA

[Jim Brown]

Hi Bill,

I recently bought a used 1K-FA from my neighbor. I use only an RCA 
keying cable from the K3 keying out to the 1K-FA. When the amp is in 
Operate mode, a quick dit or tap on the mic will allow it to sense the 
frequency and switch to the right band. I run my KPA500 and Alpha 87A 
the same way, although both have a serial port.


One thing I learned about the 1K-FA that may or may not be true of the 
1.3K-FA is that it remembers last antenna settings for every band, and 
that the signal comes through the tuner for RX. If the amp is on another 
band, I often don't hear much when I switch bands on the radio until I 
hit that dit to switch bands on the amp.

Re: [Elecraft] [KPA500] incredible hum from PA

[Ron D'Eau Claire]

I meant when it makes noise the noise comes from the steel panel under the
transformer. Quiet ones are quiet (well, reasonably so). Working out the
assembly procedure involved doing a lot of different things to see what
ended up with the quietest assembly. 

 

I should have mentioned before that the Belleville washer under the nut must
be installed "right side up" as described on page 35 of the assy manual.
Getting beyond that will involve removing the transformer to check hardware
down in the center hole. You can follow the instructions in the manual to
check that or just wait to work with Tech Support.

 

I'm not personally familiar with the "bad transformer" issue others reported
Tech Support said occurred.

little noise so that know they're well liked.  Hmmm, maybe THAT"s why the

More to the point of the subject, I wonder if it would have been possible to

[Elecraft] Connecting the K3 to an expert amps 1.3K-FA

[Bill Roberson]

I  just got my 1.3K-FA and have been actively seeking information on cable 
connections from the K3 to the amp for automatic following of the amp from the 
K3.  I guess an FDTI cable from the K3 to a computer USB port would allow 
computer control of the K3, but what cable connections are needed from the K3 
15 pin connector and/or the DB9 pin connector to the amp?  I have the relay 
connected and did not connect the ALC as Elecraft stated, but I would like the 
amp to come on when I turn on the K3 and follow the band/frequency changes.

Re: [Elecraft] KXPA100 --> KX3/PX3 Question

Bob, Ryan, and Don -


Thanks for the replies! After looking at the PX3 manual I see what a simple 
connection it turns out to be! Just need to run the PC connection from the 
KXPA100 and not the PX3, thus freeing up the ACC1 port on the PX3.

Happy Holidays to you guys and everyone else on the reflector - 73…

Re: [Elecraft] [KPA500] incredible hum from PA

[Matt Murphy]

Mine is silent during normal use, but when someone in the house prints
something using the laser printer that is on the same circuit, the
transformer gives off a brief groan.

I don't think this means my transformer is defective, would anyone
disagree?

[Elecraft] KX1 For Sale

[Skip Davis via Elecraft]

I have a KX1 three bands (40, 30, 20 MTR) works very well about 4 watts on all 
three bands
with 12.5vdc power supply. This little gem has the built-in ATU and includes 
the KXPD1 paddles.
I don't use it much since my KX3 arrived, and I'm thinning out my surplus

Re: [Elecraft] [KPA500] incredible hum from PA

[Jan Ditzian]

David,

The below statement is absolutely true.  I am an industrial psychologist 
(really), and we have made some discoveries about why certain industrial 
processes sometimes work and sometimes don't. One of our earliest 
discoveries was the answer to the question: How may psychologists does 
it take to change a light bulb?  The answer is that it takes only one 
psychologist to make the change, but the light bulb must SINCERELY want 
to change, and the process may require up to five years of weekly 
50-minute sessions before the change is fully effected.


When DXing, remember that the DX LIKES the hams around you more than it 
likes you, so you have to wait until the loved ones are taken care of 
before you get your turn.  This does not always hold when operating CW.


Jan, KX2A (the first KX2)

Yeah, but you have to realize, electrons LIKE to run around madly.  They
LIVE for the opportunity to be driven by that strange (to them)
electromotive force, regardless of whether it's in one direction (DC) or
back and forth (AC), just as horses luv to run.
They live basically a very nomadic life, jumping from one nucleus to
another. They get sluggish if not driven regularly.  This is why old stock
vacuum tubes can fail while just sitting on the shelf.
Electrons also appreciate the applause as horses do when they perform, but
seldom get to enjoy it.  So, when you make them run, at least provide a
little noise so that know they're well liked.  Hmmm, maybe THAT"s why the
transformer hums?

More to the point of the subject, I wonder if it would have been possible to
use a brass bolt or maybe even nylon mounting hardware for the big toroid?
Probably not worth the effort is a simple re-tightening can fix it.
( You'll just have to provide some outside method of showing your
appreciation to the electrons for their efforts.)

Re: [Elecraft] KXPA100 --> KX3/PX3 Question

[Bob N3MNT]

There is a ACC1 line out of the PX3 that the amp cable plugs into.  See page
9 of the PX3 manual.

Re: [Elecraft] Setting the KX3 up for JT65

Subject: Setting the KX3 up for JT65

I’ve been away from JT65 ops with my KX3 for so long I forgot what to do…I have 
used t5he KX3 in JT65m before but been many months so need to restart.

I have WSJT running on my Microsoft Surface Pro 2 and haven’t messed with those 
at all, e.g., CAT, 8 data, 2 stop, etc.

The decode works well.

But, when I connect the audio from the computer to the mic in jack the kx3’s 
transmit light comes on and stays on. I’ve seen this before but forget what I 
am doing wrong…..I believe I’ve got something set wrong on the KX3 menu as my 
audio levels on the computer haven't been tampered with.

I asked Don Wilhelm for his thought via a separate e-mailm and he provided good 
info but didn't help - thanks, Don...now looking to see if someone has 
experienced these exact symptoms...

Re: [Elecraft] [KPA500] incredible hum from PA

[kevino z]

Nice! 
Sadly, torquing it down to the spec (it was assembled by Elecraft just under 
the spec, by the way) made zero difference. But your post made me smile so 
thank you. Haven't done that since I got the amp powered on.

Re: [Elecraft] KX2 Memory Operation Question

[rfphelps]

Thanks to Don, Bill and Bill for your responses!

Don's response about the use of "channel hopping", with a few extra words,
solves the dilemma of having a freely tunable VFO on 60 meters.  When you
recall any one group of ten memories (5 CW and 5 USB) with an "*" as the
first character in the memory channel name, the VFO A knob does nothing but
cycle from one stored "*" channel in that group to the next in a continuous
loop and the VFO "B" knob does nothing at all related to frequency.

The other half of the answer is that memory channels in these rigs serve
only as a 'reminder' to be placed into the freely tunable VFO for use.  I
was expecting memory behavior to be akin to what you find on VHF/UHF FM
rigs.  Obviously, that is not the case.  Problem solved!

Regards,
Dick,
K1SW

Re: [Elecraft] KAT3A Question

Kim,

The KAT3A fits in any K3S, with or without the KPA3.
If you have need for a tuner, you will like it.

option?

Do you feel it is a nice addition to the rig?

Are you pleased with the performance compared to other external ATUs on the 
market?

Thanks in advance.

Thanks Ron. I'll open it up and measure it with a torque wrench. Then wait for 
Elecraft tech support to call back. Sometimes it's a drag living on the East
