Re: [Elecraft] Is it possible to generate 1750Hz tone on HF with the K3 ?

[iain macdonnell - N6ML]

Touch-tones are DTMF (dual-tone multi-frequency). CTCSS is Continuous
Tone-Coded Squelch System. They're quite different animals ;)

Audacity as a tone-generator function. I'd try that first.

Re: [Elecraft] K3 key clicks

[Bill]

Bill,

I recently had a similar report that I was clicking and had spurious
radiation up and down the band.  I borrowed a spectrum analyzer and
confirmed that the K3 was indeed producing lots of spurious radiation.  

I contacted Elecraft support and within one day they helped me trouble shoot
the problem down to the component.  In my case Q4 on the LPA board had
failed.  I replaced Q4 and that cured the problem.

I suggest you contact Elecraft support by email (they responded to my email
almost immediately).

Good Luck and 73

Re: [Elecraft] K3 key clicks

[Guy Olinger K2AV]

To confirm what Geoff said, if your antenna has some kind of diodic
contact, then the arc-over at the beginning of each baud, and the cessation
of arc at the end, will create beautifilous klix mostly heard by
locals.   Having
a jumpy SWR is not good.

The arcing could be in coax and connectors instead of in the antenna, but
happening only on one band (is that true?) points more at the antenna.

You may need to take down the antenna, clean, regoop and retighten all the
connections. If you find carbon traces, you may have more problems than
just connections.  If you have traps in the antenna, those can have a
problem that you can't repair.

Engage your neighbor in chasing down the problem.

73, Guy.

Subject: Re: [Elecraft] K3 Front End Protection

Fred,

The best source of good information that I have found on operating multiple
radios safely is the book by George Cutsogeorge, W2VJN: "Managing
Interstation Interferrence".  It covers all the issues with running SO2R as
well as other multi-transmitter configurations, and provides techniques to
measure interference and mediate it.

The book is available from Array Solutions here:
http://www.arraysolutions.com/Products/Books/W2VJN_Interference.htm

Antenna isolation is the name of the game and, particularly with QRO,
requires a great deal of care and planning.  I run 100W in an SO2R
configuration with 2 K3's on a small city lot.  My solution to the isolation
problem has been the use of W3NQN bandpass filters and antenna geometries to
minimize interaction.  Using W2VJN's analysis techniques and employing some
of the possible solutions noted by him, I can operate safely and have
confidence that I am not damaging my K3's receiver.

Re: [Elecraft] KUSB Noise Query - K3

[Mike Harris]

A few years ago I was receiving noise from my PC on 6M, via the serial 
interface cable.  I was also receiving it when using the KUSB of the 
time with the Prolific chip-set.


I made a new serial cable using CAT-6 and the technique used in the 
"K9YC RFI-Ham.pdf" tutorial, page 38.


This significantly reduce the noise and interestingly when I placed it 
in series with the KUSB it had the same effect.  My new serial cable was 
about 3 metres long and I was going to make up a short version to see if 
it had the same effect.  Unfortunately I never did.

Mike VP8NO

Hi Folks,
I posted a query about K3 Serial ports a few months back - we could not get the 
K3 to work properly with the RS232 connection. It turned out to be a fault with 
the sound card, which took out the serial connections.
When I first built the K3, I bought a cheap Prolific USB converter, which 
radiates awful noise over the spectrum. I decided to bite the bullet and buy 
the proper lead, which arrived today.

Using my Toshiba laptop, on battery power, I get a couple of s points of noise 
on 10M with the KUSB connected and HRD fired up. This is using my
2 element DJ4VM quad, which is fed with 300 ohm twin into the shack, i.e. near 
the laptop.

On LF, I can hear the pulsing information, in sympathy with the flashing LEDs 
on the KUSB on 160M at quite a high level. I can even detect this when fed into 
a Marconi dummy load. The K3 and the tuning units are bonder to an RF earth - a 
copper stake about 8 feet away from the K3.

I have tried choking the USB lead at the laptop end, which does reduce the 
noise to a degree.

The question I have is - am I being unrealistic in expecting zero noise to be 
radiated from these adaptors?
Does anyone else have this problem - or has anyone looked for it?

It is not very noticeable on CW or SSB. To hear it best, listen in the AM mode 
with the AGC off. On SSB it sounds like band noise.

Is this a problem JUST with USB adaptors or can I expect silence when 
connecting a computer via RS232 to RS232.

If not we are sacrificing a low noise floor for the convenience of computer 
control.

Any views appreciated,

Re: [Elecraft] K3 key clicks

[Geoffrey Mackenzie-Kennedy]

Bill,

The clicks which your neighbour heard could have been caused by something in
your antenna or feeder arcing over, or possibly an intermittent
contact.I note that you said that sometimes your Cushcraft vertical "has
high SWR spikes", which suggests that something in your feeder or antenna is
sometimes misbehaving.

QTH in Glade Park CO with a K3 and a Cushcraft vertical antenna.  (Much
nicer antennas going up in the next few weeks and more power once I get
220V to the shack).

I have a neighbor, Jerry K0DU, who lives about 4 miles away and is an
active contester.  We can see each other's QTHs from our respective shacks
across a high elevation Colorado plateau.  Needless to say we have no
trouble hearing each other.

I have noticed that I can get within 2-kHz of Jerry when he's operating CW
with at full 1.5-kW output with no clicks or elevated tx noise.  I can see
a giant signal on the P3 but can't hear a thing once I'm 2-kHz either
side.  This underscores how nice the K3 rx is.  I have a full set of
accessory CW roofing filters.

After the 10m test recently Jerry emailed me  "...(Jerry's guest op) came
across you several times on CW... heard buckshot or key clicks out of the
pass band of our receiver up & down the band"  This suprised since I had
noted during the contest how close I could operate to Jerry.  And he was
running his linear and I was operating barefoot.  Jerry has a FTdx5000 so
I don't think poor selectivity or bad rx design is the issue.  I confirmed
that Jerry's 5000 did not have the NB engaged during the 10m test.

What can I do to check my K3 for transmitted key clicks and other unwanted
emissions?  How to do to eliminate same once I confirm the problem?
Frankly, I Jerry's transmissions don't bother me reciprocity didcates than
my transmissions shouldn't bother him especially with an
order-of-magnitude different to transmitted power.

The Cushcraft vertical (an R8) sometimes has high SWR spikes.  Since its
being decommissioned soon and I've been running low power I haven't
bothered to trouble shoot it.  Could this be contributing to the
clicks/"buckshot"?

I'll run some tests with Jerry after I have a plan of attack.

Re: [Elecraft] Why are my messages being cut off at the subject line?

[Ingo Meyer, DK3RED]

Hello John,

First of all: Please send emails via the Elecraft mailing list only as plain text. Your 
request was a blank email body (beside the footer).


The first bounding factor is the internet provider. For example AOL cuts the subject line 
to about 38 signs, Yahoo to 47 and Hotmail to 45.


The second bounding factor is the mail client at the receiver. Mobile phones e.g. can 
display less than this signs.


If you would like to write a novel, please use the body. The subject is a line 
(!).

73/72 de Ingo, DK3RED - Don't forget: the fun is the power!

Re: [Elecraft] K3 key clicks

[Eric Swartz WA6HHQ - Elecraft]

Also note that the Blocking Dynamic Range of the FT-5000 is approximately 13-15 
dB worse than the K3's, as per the Sherwood and ARRL lab test data. That mean 
his rx will desense on much weaker local signals than the K3.

Re: [Elecraft] Why are my messages being cut off at the subject line?

[Don Wilhelm]

John,

The Elecraft list will do that to messages that are sent as html. Switch 
your email client to send only plain text - or remember to turn your 
reflector posts into plain text before sending.
I don't know which email client you are using, so you will have to look 
at its help file to find out how to do that if you don't already know.

Make sure his NB was off, as that will cause rx artifacts on all strong signals.

Re: [Elecraft] Selling my K2.

[Keith Heimbold]

I have had bad experiences buying ham equipment on eBay and like Fred focus on 
QTH.com or qrz.com for used equipment. Burned by radiomart 2x, and a bad old 
skool Yaesu tube amp. These three experiences has made me move to those 
websites that are actually run and managed by ham operators. 

I do use ebay and have had excellent experience buying discontinued Geoffrey 
Rowley Vans circa 1999/2000 on eBay and a certain pair of Perry Ellis pants 
that I like wearing.

Re: [Elecraft] Selling my K2.

[Dyarnes]

Fred and All,

I think Fred's comment is a bit excessive.  It's a shame he had a bad 
experience, but the same thing could have happened if he had used almost any 
other "venue" for selling gear, like Eham, or QTH, or whatever.  You can't 
just blame Ebay for your own mistakes.  His comments about being more 
careful about just how you effect the transaction are more appropriate. 
Truth is, you can make a bad deal anywhere!


I don't use Ebay a lot, but I have made a few acquisitions through it. 
Fortunately, they all turned out O.K.  I guess I was just lucky.  Like Fred, 
I'm somewhat cautious about some things I see there, but that's mainly 
because it is so wide open.  Half the time you really don't know who you are 
really dealing with.  Usually, though, you do have the option to contact the 
seller first, so it doesn't have to be totally blind faith.


In any event, if you have any significant concerns, you should probably 
follow Fred's suggestion and get some sort of assurance that you have 
recourse.  You should probably do that with any 2nd hand acquisition, 
regardless of where you get it.  I think Ebay has some sort of "problem 
resolution" process, but I don't know how effective it is since I've never 
had to use it.  If it has any value at all, it may be better to buy there 
than on some other venues.  However, I think the first rule of any such 
transaction should be to have at least some idea as to who you are dealing 
with.  If it's some "phantom", hiding behind some obtuse ID, you don't have 
much upon which to place your faith.  I also have another rule--"When in 
doubt, pass!"  If you can't get the assurances that make you reasonably 
comfortable, I'd let the deal go.  Except in rare instances, there is almost 
surely going to be another equally reasonable deal, if not better, coming 
down the pike.  Personally, I have to keep reminding myself of this last 
rule.  It's hard not to get somewhat excited (and possibly foolish) when you 
see a good deal come along.


Dave W7AQK

I make it a point of never buying any radios on eBay usually there is a

[Elecraft] My Christmas wish.

[bill . va3ol]

Wayne and crew:
Is there a way to make the CW/Data display  full time?

I don't know how many times I have been in a cw contact, just above my
abilities, and looked at the display; for a fill; and saw the VFO B
frequency instead of the needed fill.

Generally when I am in conversation I really don't care about VFO B. But I
do care about the information being decoded - or not.

Thanks

Bill, VA3OL

Subject: [Elecraft] K3 key clicks

I am currently operating barefoot at my new-ish (moved here one year ago) QTH 
in Glade Park CO with a K3 and a Cushcraft vertical antenna.  (Much nicer 
antennas going up in the next few weeks and more power once I get 220V to the 
shack).

I have a neighbor, Jerry K0DU, who lives about 4 miles away and is an active 
contester.  We can see each other's QTHs from our respective shacks across a 
high elevation Colorado plateau.  Needless to say we have no trouble hearing 
each other.

I have noticed that I can get within 2-kHz of Jerry when he's operating CW with 
at full 1.5-kW output with no clicks or elevated tx noise.  I can see a giant 
signal on the P3 but can't hear a thing once I'm 2-kHz either side.  This 
underscores how nice the K3 rx is.  I have a full set of accessory CW roofing 
filters.

After the 10m test recently Jerry emailed me  "...(Jerry's guest op) came 
across you several times on CW... heard buckshot or key clicks out of the pass 
band of our receiver up & down the band"  This suprised since I had noted 
during the contest how close I could operate to Jerry.  And he was running his 
linear and I was operating barefoot.  Jerry has a FTdx5000 so I don't think 
poor selectivity or bad rx design is the issue.  I confirmed that Jerry's 5000 
did not have the NB engaged during the 10m test.

What can I do to check my K3 for transmitted key clicks and other unwanted 
emissions?  How to do to eliminate same once I confirm the problem?  Frankly, I 
Jerry's transmissions don't bother me reciprocity didcates than my 
transmissions shouldn't bother him especially with an order-of-magnitude 
different to transmitted power.

The Cushcraft vertical (an R8) sometimes has high SWR spikes.  Since its being 
decommissioned soon and I've been running low power I haven't bothered to 
trouble shoot it.  Could this be contributing to the clicks/"buckshot"?

I'll run some tests with Jerry after I have a plan of attack.

Re: [Elecraft] Selling my K2

[Stephen Victor]

Gil-
If you just do CW portable, why not get a KX1 with the included paddles?   Much 
less expensive than the KX3.  And you can keep your K2!   Why sell something 
that you put so much into?
 
With the K1, I carry three items, a battery, the K1, and my paddles.
With the KX3, I'll have only one, using the attached paddles. That also
means a Pelican 1200 case Instead of the 1400 I use for my K1... I can
also use the KX3 at home like I do my K2. It's quite a bit more money
for me, but if I also sell my Icom IC-271A, I'll be getting close ;-)

[Elecraft] Cheap and Easy SDR

[Wayne Rogers]

I've been watching and waiting for someone to broach this subject.  Bob 
Nickels, W9RAN, wrote an article in January QST about using the DVB-T dongle as 
an SDR.  Anyone looked at using this for a spectrum display on the K3?  
Thoughts?

Matt & Brian, thanks for the suggestions. This KUSB is the latest type,

I'll look up the HS19.

Re: [Elecraft] KUSB Noise Query - K3

[Scott Monks]

    Try "disconnecting" the K3 from the program without touching anything 
else.  I recently discovered that if I "disconnect" my logging program (so it 
is not directly controlling my K3) it will reduce noise level on 15m, about 
half, making weak signals very readable.  When I opened the communication and 
control with the program the noise came back--noise or no as I activated or 
dis-activated the control function.  

    I am not experienced enough with this type of control to pinpoint the real 
source of the noise or yet how to control it, but it is there.


However, it is frustrating for me because now I can hear them but my signal is 
too weak to work them!!  hi, hi

USB uses differential signaling.  Your problem may not be conductive noise, but 
instead it could be radiated directly from the adapter, where the ferrite won't 
help.

KeySpan makes a USB - serial adapter that is pretty much noise-free.  Its 
model  is HS19, I think.

Hi Folks,
I posted a query about K3 Serial ports a few months back - we could not get the 
K3 to work properly with the RS232 connection. It turned out to be a fault with 
the sound card, which took out the serial connections.
When I first built the K3, I bought a cheap Prolific USB converter, which 
radiates awful noise over the spectrum. I decided to bite the bullet and buy 
the proper lead, which arrived today.

Using my Toshiba laptop, on battery power, I get a couple of s points of noise 
on 10M with the KUSB connected and HRD fired up. This is using my
2 element DJ4VM quad, which is fed with 300 ohm twin into the shack, i.e. near 
the laptop.

On LF, I can hear the pulsing information, in sympathy with the flashing LEDs 
on the KUSB on 160M at quite a high level. I can even detect this when fed into 
a Marconi dummy load. The K3 and the tuning units are bonder to an RF earth - a 
copper stake about 8 feet away from the K3.

I have tried choking the USB lead at the laptop end, which does reduce the 
noise to a degree.

The question I have is - am I being unrealistic in expecting zero noise to be 
radiated from these adaptors?
Does anyone else have this problem - or has anyone looked for it?

It is not very noticeable on CW or SSB. To hear it best, listen in the AM mode 
with the AGC off. On SSB it sounds like band noise.

Is this a problem JUST with USB adaptors or can I expect silence when 
connecting a computer via RS232 to RS232.

If not we are sacrificing a low noise floor for the convenience of computer 
control.

Any views appreciated,

Re: [Elecraft] K3 Front End Protection

[Stan Gibbs]

Fred,

The best source of good information that I have found on operating multiple
radios safely is the book by George Cutsogeorge, W2VJN: "Managing
Interstation Interferrence".  It covers all the issues with running SO2R as
well as other multi-transmitter configurations, and provides techniques to
measure interference and mediate it.

The book is available from Array Solutions here:
http://www.arraysolutions.com/Products/Books/W2VJN_Interference.htm

Antenna isolation is the name of the game and, particularly with QRO,
requires a great deal of care and planning.  I run 100W in an SO2R
configuration with 2 K3's on a small city lot.  My solution to the isolation
problem has been the use of W3NQN bandpass filters and antenna geometries to
minimize interaction.  Using W2VJN's analysis techniques and employing some
of the possible solutions noted by him, I can operate safely and have
confidence that I am not damaging my K3's receiver.

Re: [Elecraft] KUSB Noise Query - K3

[Matthew Zilmer]

USB uses differential signaling.  Your problem may not be conductive noise, but 
instead it could be radiated directly from the adapter, where the ferrite won't 
help.

KeySpan makes a USB - serial adapter that is pretty much noise-free.  Its model 
 is HS19, I think.

[Elecraft] Tune and CW power levels in version 4.60

[Jack Colson]

I just upgraded to mcu 4.60 and observed that when adjusting the power out on 
CW to a suitable value to drive an amplifier then switching to tune the power 
is at almost full (90+watts).  Is this a change from earlier mcu versions or my 
bad memory?

After setting the tune power out to a lower value and using it at that level 
the next time you go to use the tune it is back at almost full output.  

Help!

Hi friends, i had not trusted using SMPS, had tried some and the noise
level was never acceptable, however last two days i'm using a new SMPS
Wouxun SPS30 with my K3/P3 and i checked noise level of this PS is
really low, i have not been able to detect it visually on P3 nor
acoustically. 30 Amps on small package is great!, K3/P3 and SMPS great
combination.

[Elecraft] K3 Front End Protection

[Fred Smith]

I have saw this posted before but not quite in this respect. I'm using 2
K3's with a Array Solutions SIXpack antenna controller SO2R, using 3
different antennas for HF a beam covering all bands 10-40m, vertical 10-160m
and a OCFD @ 55' 270' long 10-160m.

 

The OCFD is using the same tower as the beam only 10' from the feed point.
The vertical a Hy Gain AV-18HT with a top mounted kit for 160m is only about
125' from the tower very good radial field.

 

My "B" station K3 is a full Elecraft KPA500/KAT500/W2, the second "A"
station is a K3/P3-SVGA into an Alpha 87A legal limit + Palstar HF-Auto.

 

With these power levels I don't want to tempt fate but may very well like to
use both radios at the same time while monitoring another band on the other
radio and a quick call once in a while. I have looked at several front end
protectors but they to be all for just receiving antennas and preamps no
transmit ones Am I correct not to trust the built in protection in the K3
for this? It's a great radio but don't want to destroy it either by running
that much power in antennas so close.

 

If the K3 cannot handle this power could anyone guide me to a source that
sells something that meets my needs.

 

Thanks to all for your response.

 

73,

Fred/N0AZZ

[Elecraft] K3 + SDR-IQ and regular CW operation

[KD7YZ Bob]

Howdy K3' people:

I was wondering what precautions are taken, or I need to invoke, when I
use any form of transmitting?

At present, the SDR-IQ is connected to the K3's IF BNC. K3's output is
through KAT500 then outside to the antenna some distance away at 80 to
85 feet AGL. Power, while I am testing, is circa 5 to 10 watts.

So I keyed the K3 a few times; called CQ, and so forth. I see my own
trace on the WF of CW-Skimmer, which is set to operate with SDR-IQ as
its "Input" .

Am I golden? Or am I about to overload the K3 and kill it?

I have built more than 500 K2's and other Elecraft kits.  Let me build one for 
you.   My prices are reasonable, and you receive a brand new radio with the 
options you want.  Please respond off of the reflector. 73AlanW1HYV
