Another reason for private conversations is that's the way many of us old
time newsgroup users were taught. If it's of obvious interest to the entire
group, then reply via the group. If it's specific to the original poster,
reply via email. BUT then it is also the responsibility of the original
poster to summarize and post the replies received, along with a "thank you".

David,

Your comments about the ease of use of the ACLog program for "casual" users
is EXACTLY why I was hoping to find a fix for the DX spotting issue I have
with ACLog and my K3.  I didn't want to give up the simplicity of ACLog, but
had hoped to make it work *fully* with the K3.  It does everything I need
(and intuitively) except a smooth spot.  I am resistant to change with
something I've used for so many years.  But, I guess one can't have
everything.

Terry, W0FM

Hi Jim,
 
I have been using ACLog for about 2 years now.  I find it simple, easy to
use, and without a lot of complex features that are of no value...to me.  I
am a DX'er and an extremely casual contester (for the DX value).  ACLog
reports K3's band and exact frequency; which is all I really want it to do
for logging purposes.  I don't use it to control a rotator  (since my wire
antennas and vertical don't need rotators!) and I don't use it to report DX
spots;  I use the standalone DX cluster program DX Summit for that.  I also
find the program easy to use for my LoTW uploads.
 
I have tried several other logging programs such as logger32, Ham Radio
Deluxe (which I use for general rig control and digimodes), DX Keeper, etc.
I find them all too bloated with features I have no use for, and which
require a learning curve that I don't have the time for.  One good thing
about ACLog (which is true of many logging programs) is that it will export
your log in ADIF format.  If you chose to switch to another logger, it is
relatively painless to export from ACLog and import into your new logger of
choice.
 
These are my experiences for what it's worth.....

When you enter "groups" at the shell prompt, what is returned?   It's
likely that you need to add your username to the dialout group.  You will
need to log out (at a minimum) and log back in after making the change.

I got my invoice last Wednesday for my kx3 and immediately called to change
my shipping to next day air since I needed to leave Thursday for Hamcomm in
Plano and my contest QTH for the weekend June VHF contest.

Well, when I got my shipping notice Friday it was marked to be sent UPS
Ground and would be delivered Thursday nite.

After I calmed down I tried over the weekend to get UPS to change the
delivery to will-call at the UPS center in the next town.  I was hoping to
be able to pick it up on my way out to Dallas.  No such luck.

The great part: I called Elecraft at 8:20 their time this morning and talked
to Madelyn to see if she could get the delivery changed to will-call.

She called me back about 20 minutes later and told me she had cancelled my
shipment and sent me another kx3 overnite as I had requested.  Now, that is
service!  Great job Madelyn and Elecraft!

If you are using a USB converter rather than a rs-232 connection it may be
your problem as many of the USB converters do not give you a full featured
connection.

Subject: [Elecraft] [K3-KPA500] SWR jumps up with 5 second key down
To: [hidden email]
Message-ID: <[hidden email]>
Content-Type: text/plain; charset=us-ascii

I have installed a new antenna and have strange changing swr. When testing
with RigExperts meter I find good resonance at say 15m (21.200). With the K3
at 100 watts reading is 1 bar on K3 meter and 1.0 on KPA500 (STBY). When I
bring the amp online and drive it at 200 watts, all is still good even with
a 15 second key down period. Driving the KPA500 to 275 watts, still okay
with key down, although the KPA500 meter now shows 1.1. BUT when I increase
the drive a little more (300 watts) the swr jumps up to 2.5+ and the KPA500
shows REFL HI and drops into STBY.  

And here is the kicker...NOT ALL THE TIME!

So I think it has to be in the coax. But the 75feet of RG213 is brand new
premade from Cable Xperts with the connectors.

I will try a different coax. Any other suggestions?

What happens when you run the KPA-500 into a dummy load? If all is well, I
would guess that something is changing under high power and affecting the
load.

Hi Nate,

Blast! As soon as you mentioned "groups" the penny dropped, I've no idea why
I didn't think of that sooner, I feel a right wally now :)

Thanks mate, all systems are go, now all I've got to do is to rid myself of
Ubuntu 9.1 and reclaim the partition, let the fun begin.

Thanks mate.

Mark has an excellent point, especially if you have a ferrite core
transformer (balun, etc.) somewhere in the antenna system. One thing that
can cause that behavior is heating of the toroid core. At a certain
temperature, the core's magnetic properties change dramatically, changing
the inductance and so causing the SWR to change.

Mike,

My first guess is that it is not the coax, but attach a dummy load to
the antenna end of the coax to test it under full power just to be certain.

The most likely thing is that something in your antenna system is arcing
at the higher power.  End insulators?  Vegetation touching the antenna
wire? center insulator arcing? or balun failing at power?

Don W3FPR

My bet will be on a bad connection someplace after the amp. With power
something is shorting ... could be in coax connector, antenna, etc ... been
through that. Once had found an elevated radial on 160 inverted "L"  had
dropped and touching a tree limb was the problem.

Jump back down to Ron's input.
I had that exact same scenario with my OCFD.  As soon as I transmitted any
length of time on CW above 250W the SWR would jump up and the KPA500 would
fault. The problem was a too small torroid 4:1 balun.  I bought a 5KW balun
from Hy Power Antennas and the problem went away. Just because the balun is
rated to 5KW doesn't mean you have to use that much power.

Mark has an excellent point, especially if you have a ferrite core
transformer (balun, etc.) somewhere in the antenna system. One thing that
can cause that behavior is heating of the toroid core. At a certain
temperature, the core's magnetic properties change dramatically, changing
the inductance and so causing the SWR to change.

What happens when you run the KPA-500 into a dummy load? If all is well, I
would guess that something is changing under high power and affecting the
load.

Subject: [Elecraft] [K3-KPA500] SWR jumps up with 5 second key down


I have installed a new antenna and have strange changing swr. When testing
with RigExperts meter I find good resonance at say 15m (21.200). With the K3
at 100 watts reading is 1 bar on K3 meter and 1.0 on KPA500 (STBY). When I
bring the amp online and drive it at 200 watts, all is still good even with
a 15 second key down period. Driving the KPA500 to 275 watts, still okay
with key down, although the KPA500 meter now shows 1.1. BUT when I increase
the drive a little more (300 watts) the swr jumps up to 2.5+ and the KPA500
shows REFL HI and drops into STBY.

And here is the kicker...NOT ALL THE TIME!

So I think it has to be in the coax. But the 75feet of RG213 is brand new
premade from Cable Xperts with the connectors.

I will try a different coax. Any other suggestions?

I hate to say this but cable experts does not have a stellar record with
their installed connectors.  I would cut them off and install new ones.

Okay, some more info. The KPA500 does not have a problem with the inverted
vee for 40 meters, but I will set it up with a dummy load to check just in
case. And I will try the dummy load at the antenna end of the coax as a test
tomorrow.

The antenna is the new Q-52 2 element yagi five band from N6BT. It uses
relays on both the driven element and the reflector to cover 20m (high and
low) 17, 15, 12 and 10. I have contacted Tom Schiller who says he has tested
the antenna with 600-700 watts on CW so power should not be a problem. I
also thought the high power might somehow be keying the relays as the
eight-wire control cable parallels the coax 4 feet across the boom, down the
30 foot mast in through the garage in a pvc conduit then into the shack. I
tried moving the control box away from the amp and experimented with running
the coax a different route into the shack, although the coax and control
cable still came down the mast next to each other. None of these had any
affect.

What Antenna are you using?  Not only the balun needs to be rated for your
power but the coils and wire does too.  Many mfgrs overrated their
equipment.  For 500 watts use kw rated antennas.  RG 213 is good but wire
and loading need to be #14.

All that is needed for K3 control are TXD, RXD, and Ground.  DTR and RTS are
used for PTT and Key-in (see page 18 of the manual), not serial
communications.  The problem, as described earlier, is that the program is
setting the mode first and then the frequency.  I've asked other program
authors to reverse those two commands and they have willingly complied.  The
sequence is important on the K3 as mode is retained on a per band/VFO basis
and it acts on commands as autonomous units.  To me it seems as though
setting the freq first and then the mode should be the proper sequence for
all rigs, not just the K3.  Perhaps programs should be smarter (and some
likely are) where after changing the frequency the mode is polled and then
changed only if necessary.

The only problem with USB to serial adapters when controlling the K3 is
apparently with drivers on certain legacy operating systems.  I've used a
couple of Prolific based converters on my Linux machines with nary an issue.

Not my experience. For over five decades, I have used #18 wire for many
antennas. Current antenna has segments of #18 with no ill effects at 1.5kW
output.

If all responses of "read the manual page XX" or "check the reflector

useful.  I even regret posting this just to avoid another comment.

I strongly doubt that.  Loose connector maybe, but you've probably
already checked that.  Some suggestions:

1.  Does it do it with dummy load on output of KPA500?

2.  Does it do it with dummy load on far end of coax in place of antenna
[not always easy to do]?

3.  Does it do it with another antenna [if you have one for 15]?

4.  Does it do it on any other bands?

5.  You said it is one of Tom's multiband yagi's.  Did you tighten
everything down when you assembled it?  If I were to bet on it, I'd bet
this is your problem.

6.  Is there a balun?  If so, what happens to your TV when this high SWR
occurs?   All transformer cores will saturate at some power level, the
flux in them just cannot increase anymore, all the little magnet-lets
are already aligned.  The power at which this happens is sensitive to
the temperature, and when it does, the balun become non-linear and you
radiate all sorts of trash.  However, if I were to bet, I'd bet this is
*not* your problem.

I haven't read the rest of the email list yet and I'll bet there are a
lot of suggestions for you there by this time.  I'd have typically taken
mine off-list to you and let you publish the resolution once, however
apparently, that is poor list etiquette.  I'd like to know what the
resolution is, I occasionally have a sort of similar problem on an old
antenna that's been up for maybe 15 years.

Some people are more reserved than others and prefer private exchanges
to public broadcasts.  Just ask yourself how many people are willing to
stand up at a public gathering and voice their opinion.  It's a matter
of human nature, not "openness on the reflector".  You're making it
sound like some ulterior motive when it isn't.

Besides, as someone else just pointed out it's entirely possible for
somebody to hit the "Reply" button on their email client instead of the
"Reply List" button without really paying attention.  It's a very common
happening.

But most importantly, I've been a K3 owner for over three years (a K1
owner for much longer than that) and I can't think of ANY problem (some
of which I have complained about) with the rig that hasn't received full
and repeated discussion on this reflector from both users and Elecraft.
   I honestly haven't a clue what you're talking about.   If you're so
focused on "full disclosure", how about offering a few specifics so we
know what you're talking about instead of making such vague allegations.

By the way, this normally would have been a private reply but since you
asked ...

If I remember correctly, microHAM specifically advises *against* connecting
like that and doing updates through the microHAM device. It would seem
prudent to disconnect your microHAM device and directly connect your P3/K3
combination and effect updates in that manner.

Agree all the way. For daily logging and superb tracking (there are gobs of
awards that can be tracked and user-defined fields if you need even more), I
also have used DXLabs for quite some time (five or six years). There *is*
somewhat of a learning curve. The author of the suite (who also co-hosts an
excellent forum) recommends learning a specific piece, then learning another
one and so forth.

If you're only interested in single-op situations, N1MM is also free and is
pretty easy to set up. If you want to get involved in multi-rig or multi-op
situations, it can be somewhat more complex. In either case, the N1MM forum
has participation from the authors and is very, very well supported.

Good Day Everyone,

I was noodling around some KX1 topics on Nabble and found this posting by
W2XS from 7/08:

"For 40, 30, and 20 meters, I use a 42-foot wire with a large nut on the
end.  The wire is thrown over a tree branch.  A Pomona BNC-to-Bindng Posts
adaptor is used.  Three counterpoise wires cut to one quarter wave for each
band (approx. 33', 23', and 16.5') are connected to the ground binding
post."

My question is whether *all three* counterpoises are attached to the binding
post *at once*, or is he talking about changing the out the counterpoise as
he changes bands? I've been using a one-size-fits-all counterpoise and was
wondering if I've missed something basic and very useful.

Thx es 73

You can connect all at once. The ones for the band you are on will be
resonant where the others will not.

Yes, you can, but you will only be able to hear the other stations if you
are on CW using QSK.  It won't work on phone, because both RX's will mute
when the rig is keyed in the voice and digital modes.

Ron, CocoModem works great.  There's no need for an external sound card
device;  I have used an external USB sound card, iMic, which works no better
nor worse than the iMac built-in sound card.

Also, see http://machamradio.com/, which has links to a number of other Mac
ham radio applications.

I would not overlook the Navigator interface for use with the K3. In my
opinion it is a bit more user friendly than some of the other interfaces and
with six USB/Serial ports you will be done with that problem (CAT, PTT,
WKey, FSK, An auxiliary RS232 port) and one of the quietest USB Codecs for
those sound card apps I have ever seen. That being said i run MacLogger DX
as a logger program, Fldigi for my PSK31, RTTY etc, Flwkey for CW, Flrig for
station control. I use CrossOver and run JT65-HF and other ".exe"s I cannot
do without. You will love coin' it with a Mac.

Ron -

I use RUMLog and cocoaModem on my Mac. RUMLog can use the RS-232
interface to read the frequency from the K3. cocoaModem has been
a workhorse for my on PSK-31 (90% of my operating time after FM
repeater & SSB.)

My general PSK operating mode is to set the K3 to the base
frequency for the PSK sub-band and lock the VFO (hold LOCK).
When I start a QSO, I narrow the bandwidth of the radio to
150-250 Hz using the Lo and Hi knobs. When I end the QSO, I have
a macro to open the bandwidth to 2.3 KHz to fill my 2 KHz
waterfall. I use the RF gain knob to control over-driving the
Signalink interface. I use a Signalink because I have a MacBook
Pro which can only do audio one way at a time.

Hi Paul,

I own the K2 and K3.  Like you, I'm not a contester.  I actually prefer the
sound of the K2 on CW.  To me it sounds warmer and smoother.  The tone of
the
K3 isn't bad and if I didn't have a K2 to compare it to, I probably wouldn't

notice.  The K3 sounds a little rough or raspy to me as compared with my K2.

To: [hidden email]
Message-ID: <[hidden email]>
Content-Type: text/plain; charset=us-ascii

If anyone has used an ALS-600 with their K2 I'd like to hear any tips you
may have.

I have a K2 with the PA/ATU outboard in separate enclosure that I want to
use to drive the amp. Is there nothing more to do than to install a cable
from the K2/100 PA KEY OUT to the ALS-600's RELAY jack (and RF OUT to RF IN,
of course)? I've read that at least with the K3 hooking up ALC is not needed
(of course, I have to take care not to use too much drive from the K2).

I have parts on order for the AD5X QSK mod, but they probably won't be here
for quite a while. What would you recommend that I set the QSK delay to in
the K2 to avoid switching while hot? I don't mind giving up fast QSK for the
time being.

tnx es 73,

If you're using a Mac, look at MacLoggerDX, Aether or RUMLog for logging and
cocoaModem for digital modes.  That suite of software (cocoaModem works well
with either MLDX or RUMLog) functions quite well with nothing more than an
iMic sound card (so Operating system sounds do not reach the radio) and a
basic USB to serial converter.

If you want everything in one box, look at microHAM USB Interface III (which
works as standard USB sound card and serial converter under OS-X).  While
other interfaces provide additional capabilities, the USB III provides
everything needed for the vast majority of Mac users.

Casey,

Changing the T-R delay in the K2 will not eliminate hot switching.  The
time between the KeyOut going low and the onset of RF is close to 8 ms.
and is not adjustable.

So, yes, you will need that AD5X mod.

What the T-R delay in the K2 menu does is delay the transition from
transmit to receive.  That can be used to prevent amplifier relay
clacking on CW, but you will not have full QSK.

I would suggest you activate the amplifier relay with a foot switch (or
other manual switch) in the meantime.  The amp relay should connect the
K2 directly to the antenna if you forget the foot switch, so no harm
should come from operation like that.

73,
Don W3FPR

I had posted this previous before Nates post;

"Paul, Sound like a permissions problem, sudo chmod 777 the device and
try again.
Or, join a group with permissions, eg: dialout

run (example , use your ttyUSBx id)

[root@fedora16desk ~]# ls -l /dev/ttyUSB0
crw-rw---- 1 root dialout 188, 0 Jun  4 19:49 /dev/ttyUSB0
[root@fedora16desk ~]#

Above will show the group owner i.e dialout.

Adrian ... vk4tux"

I received that post which was sent to [hidden email], however I
dont see here it it in the nabble list, as I was trying to work out why you
did not see it.

oh well.

Thanks Don. It so happens I have a foot switch so I will use that while

Hi Adrian,

The internet world is a strange and wonderful place at times, all designed
to frustrate us.

I simply went to the GUI in Manage Users and Groups and added it there, I've
done that dozens of times, I just forgot, it must be an age thing.

Still, hopefully this thread might help someone else if they have the same
memory affliction I seem to be suffering at the moment :)

Paul.

I have always looked at a post on this reflector as a comment made among a
group of friendly, polite Hams just as one might make at a Ham club meeting.


One of the big advantages of posting on the reflector is similar to
advantage of discussing a subject with a bunch of like-minded Hams at a club
meeting: learning. Listening to others responses, being corrected politely
and clearly when we make mistakes, and hashing out many opinions on issues
is a huge opportunity to gain insights and to learn things.

People are not always polite on the reflector, just as they aren't in
person. We all have bad days. We all sometimes say something we later
realize wasn't "heard" in the right way. And there are a few - very, very
few IMX - who are just impolite people, Hi! But, IMX, some of the most
memorable and pleasurable acquaintances I've had in my lifetime were with
people who were downright rude when we first met.

I think that experiencing someone's "rough" side from time to time is a very
small price to pay to gather the community of thought, information and
experiences about an issue that public exchange provides.

Ron AC7AC

Some people are more reserved than others and prefer private exchanges to
public broadcasts.  Just ask yourself how many people are willing to stand
up at a public gathering and voice their opinion.  It's a matter of human
nature, not "openness on the reflector".  You're making it sound like some
ulterior motive when it isn't.

Besides, as someone else just pointed out it's entirely possible for
somebody to hit the "Reply" button on their email client instead of the
"Reply List" button without really paying attention.  It's a very common
happening.

But most importantly, I've been a K3 owner for over three years (a K1 owner
for much longer than that) and I can't think of ANY problem (some of which I
have complained about) with the rig that hasn't received full and repeated
discussion on this reflector from both users and Elecraft.
   I honestly haven't a clue what you're talking about.   If you're so
focused on "full disclosure", how about offering a few specifics so we know
what you're talking about instead of making such vague allegations.

By the way, this normally would have been a private reply but since you
asked ...

Subject: [Elecraft] KX1 ATU causes power to drop off...
To: [hidden email]
Message-ID: <[hidden email]>
Content-Type: text/plain; charset=us-ascii

I just finished the KX1 kit and without the tuner, power output into a 50
ohm load is about 10W on 80M, and 4W on 40M, 30M, and 20M using a Bird
meter, 50W slug. However the ATU which seems to work well in all testing,
all the relays click, etc., in TUNE the power starts out at a reading of
about 3 watts (40, 30, 20...a watt higher on 80) and falls off in about 2 to
3 seconds to about .5 watts. The Bird meter shows exactly the same power
fall off.
Also the SWR reading in all cases reads 1.0 using the dummy load. So it
seems like something is heating up (don't feel any heat anywhere) and the
power falls off...but it still always reads an SWR of 1.0 when I go out of
TUNE. When I remove the ATU and install the jumper the power is steady for
all bands (just higher on 80M).

When I activate L0 thru L3 and C1 thru C3, I get a significant change
(normal) in SWR cycling thru L0 thru L3, but cycling thru C1 thru C3, the
SWR seems to just change from 2.0 to 2.1 to 2.0    

Not sure what to look at...

So, you're posting an extraneous post to complain about extraneous
posts? BTW, the discussion of which logging programs work well with the
K3 seems to be a completely legitimate topic for this list.

Go to http://www.n3fjp.com/ and scroll down the left side of the page and you will find "Join N3FJP Users Group". There they list a number of groups to subscribe to (mostly Yahoo groups).

[N5GE-2]

I strongly disagree, but since you don't seem to mind the posting of questions
regarding other topics....

Beginning of exaggerated nonsense post:
 
I have a question for the group:

I have two K3's and I would like to know in the opinion of the group on which
side my John Deere tractor cab should I mount my K3.  Should I mount on the left
side just to the left of the oil pressure gauge or on the right just to the
right of tachometer?

I'm kind of leaning towards the left side because there are binding posts the
for accessories there.  The wires on the binding post appear #4 wire.  Would
that be heavy enough to handle the transmit amperage draw from the K3?

While I'm at it could you tell me where I should mount the antenna and what
brand you recommend for mounting on a tractor.  If I mount the antenna on the
top of the cab just above the front window frame, will the windshield wipers
have an affect on TX or RX purity?

Also I wonder if someone can tell me what sort of noise filtering I should
install and where I should put it.  The tractor is a diesel, but it does have an
electrical system that runs the computers, which brings to mind whether my K3
will interfere with the computer and the gauges on the dash.  Can anyone help me
decide what to do about that?  It might even be dangerous, so if anyone know's
the answers to my questions, please email me via the list.

End of nonsense post:

Thre is a simple one line polite non-agressive answer to a post like the one
above.  Can anyone guess what it is?

Thanks and have a nice day,

You guys have way too much time on your hands.
C'mon if a post relates to a K3,   its OK.  
Taking a stand on when a post might be weighted too much in another direction is laughably foolish.   :-)
Could I offer a diversion ?  Sudan, ST2AR is on, try working him with your K3.

Correct.

But please limit replies to OT threads in the interest of improving SNR
on the list, and so I do not have to jump in and end them.
