Subject: [Elecraft] Checking U1 for communication with the K3

I want to check my K3 for communication with my computer.

Does anybody know what value and which pin to check on U1 on the I O
board lightning strike near by hit my wireless router modem and killed
my desk top computer which was connected to my K3 rs232 port?
I do not have at this time any computer or usb/serial adapter to test
the radio with.

[Elecraft] Put my new KAT500 thru the wringers today

[KD7YZ Bob]

Howdy K3' people:

Got my factory-built KAT500 today. Despite the missing cable (paid for)
E850463, I figured out how to run it manually. They did send along a
strange 3ft RCA RG59 cable though. right now the cat's playing with it.

Getting an automatic AT, for me, was kinda just a laughing point. I
quizzed Dave about it rather heavily. Me and Marconi weren't sure young
Dave could be right on all counts since he hasn't seen the wire here.

But I thought it would be fun to switch bands rapidly, and without my
short clip-board and penciled columns of the current  settings for the
wonderful Palstar AT2K tuner.

Well, I started at 160m and went thru 60m and finished at 10m. Didn't
miss anything.

There was the clattering expected; the metering reported wonderfully
high SWR's as she tried to figure out how to match the 110' section of
450 fed with a few loops of coax at the shack end.

I got to  raise my eyebrows in that All-Too-Certain of ones-self that we
get after operating on a few continents with wire and one of the combat
tours I had a 1500 foot V-beam ... That was before most of your
respective times though.

So I was about to say "Ah HAH!" when the noise stopped.

"Gave up, did ya??" .. The last number I saw on the K3 was something like
98:1  ... hahahahahahahahaha ...

But it was quiet and now the K3 said !.1:1 "One-point-one to one?" I
asked ..

OK, I lost that one on 160 .. so on to make it fail somewhere else.

By 30 meters I was having fun because  the pragmatic side of me knew this
was going to be wa tooo KEWL ... "IF" she made it to ten. Somewhere
in 280 feet of wire at 80 feet, there must be a rotten mis-match that
the slim little beastie can't handle.

Guess I was wrong.

Kudos to Dave at Elecraft for steering me to the KAT500. K# is perched
on a thin mat of that rubber-cloth ya get at Wal-Mart sewing area. Who
knows, if I get a cable I think it will be automated.

There is a "Computer Interface Cable" which has a 3.5mm one-end and USB
the other. That's into the computer now but I have no idea who talks to
it. K3-Utility didn't anyway.

Nice piece of gear. In a week or two my 1200' wire goes up .. gotta have
something for the diversity setup. Wonder if I can bamboozle the KAT500
on that one. Coax-balun to 600-ohm ladder to the wire .. heh heh heh heh

If you don't have one and wonder if it will load into your stealth
clothesline, there is a good chance it will. Afterall, I am loading some
of the 80 foot oak trees.

KAT500: Good for the shack!

[Ron D'Eau Claire]

I'm a freelance writer who has been writing manuals for Elecraft for 11
years, so far. It's not lost on me that many of the engineering staff are
the same folks who I worked with on my first Elecraft project back in 2001. 

They have grown significantly over that time and have added a number of
people, every one of them good folks to work with.

We have the good luck to live a short drive from Elecraft central. CEO Eric
was the principal speaker at PAARA radio club last Friday night. About a
third of his talk was photos and snippets about members of the Elecraft
team. Tenure of 10+ years was not uncommon, as were newbies because they're
growing. Good vibes.
This weekend I decided to add the ATU to my KX3 so I ordered it via web.
Madelyn called this morning to say the order was ready so I drove down to
pick it up. Order was ready on arrival but I was offered an impromptu tour !

Short version is that everyone from Madelyn to David to Howard and Joseph
and Keith and ... were clearly enjoying themselves and enthusiastic about
their role and the company. LOTS of activity in assembly areas; burn-ins;
shipping, in-bound parts, etc. David was appropriately proud of the US
content of the whole product line All said, it completely reinforced my
Elecraft choices, particularly because I'm a veteran communications engineer
from Apple with experience in wonderful, and not so wonderful product
development. Real deal at Elecraft.

Re: [Elecraft] Help,advise K3/KPA500 problem

[Ron D'Eau Claire]

Well, RM, it's almost certainly something in the interconnect cable with the
DB connectors running from the K3 to the KPA500. That's what moved as you
connected the keyer. 

Since you checked K3 end, have you checked the KPA500 end? Are both
jackscrews tight?

The KPA displays the K3 output power but when I key the amp sits in
standby.The band following is not working. They just are not communicating.
Jamie suggested unplugging all the interconnect cables & reinserting them in
the K3 & KPA. Maybe a lost connection.
That had no effect. I'm open to suggestions as a starting point or if anyone

Re: [Elecraft] Help,advise K3/KPA500 problem

[Guy Olinger K2AV]

The auxbus connection on the ACC jack seems to be open.

This is the one that always gets folks...  This trouble is 95 percent
something not in all the way.  The other 4 percent is breaking a wire or
connector.  The other 1 percent is an accidental change to a menu setting.
 In particular:

Make sure that *every single connector* is in *all the way* on both boxes,
properly seated.  That means *EACH *cable connector, *skipping none*,
whether you took it out or not, checking at *BOTH* ends.

Wish I had a buck for every time that was the answer for something
"suddenly" not working.  Of course, I've only done that to myself dozens of
times.  Same answer for me, too  :>)

Re: [Elecraft] Speakers and other Bright Ideas… Maybe not so Bright...

[David Moes]

This is true in many cases.   however in many small devices like phones 
and such put decent modern drivers  in that will sound pretty good 
without all the electronic wizardry that the device uses to make it even 
better   my speaker mic was proof of that.Its amazing how the fine 
points of speaker driver  have changed  in the miniature world of today 
yet the basic principle is still the same as the good old Rice Kellogg 
design of 1924.



Where the speaker, its driving electronics and the enclosure are all 
in one package, there's great scope to compensate for all the 
short-comings of the arrangement with sophisticated (software) filters 
which you will not get when you salvage just the speaker which is not 
in itself optimised for clarity - it's the whole ensemble.

Re: [Elecraft] OT: "Tin whiskers"

Yup.  My career was in the semiconductor industry and we knew several 
decades ago that strain greatly enhanced the probability of dendrite 
growth.  I didn't see anything new in that article other than maybe the 
ability to actually watch it happen.


And to put things slightly on topic, I'd be amazed if there were any 
devices in Elecraft products that weren't fabricated with that knowledge 
in hand.

[Elecraft] KX3 s/n 29*77

[Barry Middleton]

I completed the assembly of my KX3 yesterday Sunday 9th, with no 
problems at all, followed the manual word for word. Coming up for 76 
next month my fingers are not as nimble as they used to be and I found 
medical forcepseasier to use than long nosed pliers except for the large 
nuts. I am now slowly going through the operating manual getting it set 
up to my liking, I will be taking it to my local radio club soon in the 
hope that other members will like it and want to buy one. Thank you 
Elecraft for a first class radio.

Re: [Elecraft] Speakers and other Bright Ideas… Maybe not so Bright...

[david Moes]

Interesting ideaI did that in a speaker mic that I used on an HT 
using a speaker element from a dead blackberry.   it sounded much better 
than the original.My only worry is the original speaker used and its 
magnetic shielding may be important.If I replaced it would I be 
creating potential problems if I cant shield the magnet properly.


(i dont have either KX1 or KX3  but often thought a better speaker 
driver in the K3 would be nice but dont want to take the chance of 
adding a problem)

Re: [Elecraft] K3 Abberation

[K5WA]

Paul,

One possible explanation is if you currently have CW Keying enabled via your
COM port AND you had just turned on your computer prior about the same time
as turning on the rig.  Your computer COM port randomly fires DTR/CTS
signals on power-up which would present itself as you describe.

If you don't use COM CW keying, I'm stumped.  ;-)

Hi All,

I've noticed an odd behavior on my K3.? From the time power is applied,
the TX light begins to flutter on and off in a random manner.? When it's on,


the K3 transmits, this in CW mode.? It doesn't matter which band is
selected.? 

I've just recently installed firmware version 4.60, but this has been going
on 

for a while.? This condition lasts for as long as 45 seconds, then stops on
its 

own (so far).

ANY help will be very much appreciated!

TNX + 73 de Paul? W6GMU

Re: [Elecraft] [KAT500] Please help with Mac-KAT500 interface

[Don Putnick]

Thanks, David et.al.

You're right. I've been using the Keyspan driver for the K3 Utility. I
never bothered to reload the FTDI driver after I did a clean re-install of
the operating system.

Re: [Elecraft] K3 stereo volume balance

[F5vjc]

My hearing is OK, however I do find that when AFX is enabled in my K3 the
audio is always unbalanced, ie louder in the left channel to such an extent
I don't like to use the AFX much.
I've always thought an AF balance  would be useful, at present this is only
available when the Sub RX is active.

Re: [Elecraft] K3 Abberation

[Mike Flowers]

Further do David's suggestions - do you have an RS232 keying circuit keying
the K3?  If so, a component in that circuit could be starting to fail.

Just a thought ...

Since its keying CW do you have a straight key or bug installed? a weak

[Elecraft] Checking U1 for communication with the K3

[Art Nienhouse]

I want to check my K3 for communication with my computer.

Does anybody know what value and which pin to check on U1 on the I O 
board lightning strike near by hit my wireless router modem and killed 
my desk top computer which was connected to my K3 rs232 port?
I do not have at this time any computer or usb/serial adapter to test 
the radio with.

Re: [Elecraft] K3 stereo volume balance

[Vic K2VCO]

As far as I know, there isn't. I've suggested that the CONFIG option (SUB AF = BALANCE) 
that makes the sub volume control into a balance
control also should cause it to be a balance control for the main receiver when the sub is 
off or not installed. I don't see a downside, but I'm not the programmer!

Is there a way in K3 firmware to re-balance the left and right channels
using just the Main RX. If not, is anybody using an external device that
accomplishes this task? Preferably one that is immune to RF.

Re: [Elecraft] How Tin-Whiskers Form

[Vic K2VCO]

Fascinating, as are the comments following the article. The removal of metallic lead from 
electronics that should be recycled anyway, in return for a large increase in failures, 
does not seem to me to be a good deal for civilization (some of the comments mentioned the 
removal of lead from gasoline, which in contrast was a very good decision).
There should be a name for the irrational fear of tiny quantities of substances that would 
be harmful only in large amounts -- like RF, to give another example.

No, I will not answer outraged personal emails on this subject!

[Elecraft] K3 stereo volume balance

[Mike K2MK]

The hearing in my right ear is weak. I use the CM500 headset. Using just the
Main RX, I find that my left ear is doing all of the heavy lifting. Lately
I've been using the SUB RX in Diversity (with the main antenna) so that I
can offset the stereo balance. By applying more SUB RX volume I am able to
boost the volume level in my weaker right ear.

Is there a way in K3 firmware to re-balance the left and right channels
using just the Main RX. If not, is anybody using an external device that
accomplishes this task? Preferably one that is immune to RF.

Re: [Elecraft] Big weakness in Macro's

[Rich - K1HTV]

Ed,
You probably already now this, but other K3 or KX3 users may not. Until there 
is a single command for changing between the K3's front panel mic jack, the 
rear panel mic jack or the rear panel line in, the way to make the switch is to 
use one of these macros.

Mic Input - Front Panel:  MN053;DN;DN;DN;MN255;
Mic Input - Rear Panel:   MN053;DN;DN;DN;UP;MN255;
Line Input - Rear Panel:  MN053;UP;UP;MN255; 

You can also add gain (MG0##;) and/or compression (CP0##;) settings to the 
microphone macro examples above, where ## is the desired two digit setting. Use 
your front panel MIC gain pot to set levels if you use Line Input.

For those who are interested in writing macros for the K3 or KX3, you can 
download the K3/KX3 Programmer's Reference at:

http://www.elecraft.com/manual/K3&KX3%20Pgmrs%20Ref,%20E2.pdf

Rich - K1HTV

Re: [Elecraft] [K3] autonotch now distorts SSB audio

[Bill Clarke]

You are not alone regarding problems with ANF (NTCH) distortion of SSB 
received signals.  Too bad the problem continues unaddressed - as it is 
the single remaining receive issue I have with my K3.


There is a thread about it here: 
http://www.mail-archive.com/elecraft@mailman.qth.net/msg136366.html


A couple of responses were actually explanatory and helpful - others 
were laughable detractors. The thread is worth reading. Some responders 
say they have no problem with the distortion and find it acceptable. I 
personally do not accept it, as it detracts from an otherwise nearly 
perfect receiver.


As an interim fix, I suggest you reduce the AGC SLP to a low number, 
such as 2 or 3 (the settings I use).


Bill W2BLC
