Re: [Elecraft] Sync AM and checking VFO accuracy using WWV

[Fred Jensen]

Fair question ... actually a good question.

Short answer: On vintage receivers, the VFO freq [the local oscillator 
that heterodynes to the IF freq] is switched for each band ... except of 
course if it's a Collins radio.  It's a single dial with multiple fixed 
scales but multiple frequency determining networks.  Calibrating one to 
WWV has no bearing on any of the others, and your example is correct.


For a K3 [and all like it], the "VFO" is synthesized from a single, 
non-switched source regardless of band.  Get it within 1 Hz at 80, and 
it will be within 2Hz [or so, it's digital after all] at 40. So, you 
want to to do the adjustment at the highest possibly frequency ... all 
the lower ones will be *at least* as good.


A critical factor in this procedure is that the WWV signal strength 
needs to be hign enough to discern the zero beat clearly.  I did mine at 
20 MHz when there were lots of sunspots.  At the end of 2016, you may 
need to settle for a lower WWV.  The difference will be tiny in any case.

[Elecraft] Macro command question

[John Klewer]

Learning how to do the macro thing with my K3Sperhaps it is just too
late at night but I cannot seem to find a reference to the command to set
"Line In" level

Found Mic Gain but no reference to Line in setting in Data A mode

Any help, please?

Thanks

[Elecraft] Elecraft CW Net Announcement

[kev...@coho.net]

Good Evening,
Conditions continue to challenge.  The sun is active, kind of. Noise 
levels are up from a variety of solar occurrences.  However, you can 
still hear and work folks; just not always where you had wanted to :)


   Colder than normal temperatures have brought fluffy snow. Anything 
touching it leaves a story.  The elk are easier to track.  It's fun to 
see the snow falling into a hoof print in the shade.  If you are very 
lucky you get to see them disappear nearby.  Each new storm provides a 
blank slate.


Please join us tomorrow on:

   14050 kHz at 2300z Sunday (3 PM PST Sunday)
 7045 kHz at 0200z Monday (6 PM PST Sunday)

73,
Kevin. KD5ONS

Re: [Elecraft] K3s - 80W on 160

[Brian Hunt]

A short story.
I was having awful trouble with my K3 #4113 with power overshoot with band or 
power change on 40m especially but all bands to some degree. Also max power out 
on 15m was 85w. 160m unknown since I don't op there. 

As you did, I upped the PS voltage and ran a TX Gain Cal and it got better for 
a while but wasn't a cure. 

In "fix it or break it" mode, I updated the firmware to latest production 
version (was on 5.3.8) and reran the TX Gain Cal. Not much improvement. 
Thinking maybe I did something wrong, I redid the TX Gain Cal and for some 
reason, while in the K3 utility, ran the 50 watt cal a second time. Totally 
different gain values in the status listing AND problem cured!  No overshoot 
and full output on 15m. Happy camper. 

The only thing I can think is that the power of the K3 was taking longer to 
settle than the cal software allowed giving less than ideal results. 

OK- long story and I don't know if this will help your problem but it might be 
worth a try. GL!

Re: [Elecraft] KAT500 without KPA500

[Fred Jensen]

You were quite clear, at least to me.  The answer is YES.  The normal 
setup is the K3 AUX goes to the XCVR jack on the KAT500.  It gets 
frequency info.  *If* you have a KPA500, another such cable connects 
from the KAT500 to it.  If you don't have a KPA500, that connector is 
empty.  Does that answer your original question?


I don't know about the pussyfooting. [:-)

Re: [Elecraft] KAT500 without KPA500

[Ken K6MR]

In a word, yes. It works fine.



I switch my amplifier between two K3s, but have two KAT500s. Each KAT500 is 
connected to a K3 all the time. When the K3 without the amp is tuned, the 
KAT500 follows the frequency changes. I leave mine in manual mode (for those 
bands that need the tuner) and can hear the relays click as I move into a new 
segment. AFAIK the frequency data is on the aux bus, so with the stock cable it 
will work fine. I built my own cables because my amps/tuners are in a closet 25 
feet away.

Be sure you are using LINE IN gain rather than MIC GAIN to adjust the Tx

Re: [Elecraft] K3s - 80W on 160

[John Kaufmann]

I had the same issue with my K3S.  I was seeing 80W maximum on 160 and it
would not drive my AL1200 to full power (1500W).  Redoing the power
calibration did not fix the issue.  

 

Elecraft Tech Support told me that my K3S was within spec but that
increasing the power supply voltage could yield more power output.  I ended
up increasing my supply voltage from 13.8 volts to 14.5 volts and was able
to get 90W out, which was a bit of an improvement.  There is a trim pot
inside my Astron RS-35M supply that adjusts the output voltage.

the power so it reads 100W on the K3s LCD 

bar and numerical display, the watt meter 

in the P3 and the LP-100A both show the 

wattage stopping at 81W.

 

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?

 

Thanks & 73,

[Elecraft] K3S No TX Audio via USB

[John Klewer]

OKI have read several archived email threads regarding this issue some
other hams are having without finding a resolution to my problem...please
help!

Running a new K3S with a Mac running WSJT-x for JT-65 mode

Transceiver is connected per the manual and I am able to control the K3
with my logging program (MacloggerDX) when it is so connected...in other
words I have control and communications between the computer and the XCVR

WSJT-X receive works great and able to decode signals fine.

I have selected the appropriate USB CODEC as shown in my Mac system
settings and, of course, in the WSJT-X configuration menu.

I have nothing plugged into the Line In or Line Out jacks of the K3S

There is no TX audio, listening to an external receiver or the radio's
monitor regardless of setting and regardless of Mic Gain settings (running
in USB mode for WSJT of course)

This is a brand new K3S with version 5.50 installed

My friend has the same setup except with a Windows computer and has the
same problem with his setup.

Any help is appreciated

Thanks

John, N6AX

Re: [Elecraft] Calibration using WWV and a Smartphone

[Don Wilhelm]

All,

That is a good method.

If you wish to use a computer rather than a smartphone (some of us only 
have 'dumb' phones), you can feed the radio audio into a soundcard and 
use an audio spectrum analyzer like Spectrogram or Spectrum Lab.
With the audio spectrum analyzer, you do not have to go through the 
calibration process if your soundcard/computer produces accurate 
measurements.  Go directly to SSB and you can see the pitch of the tones 
on the display.


You can download a clean copy of Spectrogram from my website 
www.w3fpr.com - look for the link near the bottom of the opening page. 
The link is to a local file on my website and has been scrubbed many 
time for virus.  I have heard that copies of Spectrogram at other web 
locations have contained viruses.

"REF CAL" to a number where
my VFO's frequency readout is exact or near this number +/- maybe a Hertz

Re: [Elecraft] Sync AM and checking VFO accuracy using WWV

[Fred Jensen]

I guess it depends on how accurate you want your K3 frequency display to 
be.  I think AM-S will warp the frequency a tiny bit to sync the carrier 
so that may not be the best mode.  I'd also go as high as you can on WWV.


Wayne suggested a method that is somewhere on the E-site which I used--

Use the highest WWV frequency that you can hear well.  USB or LSB, WIDTH 
to 500-800 Hz, SHIFT so can hear the carrier beat note [it will be very 
low].  CONFIG-->REF CAL, wait for a tone-less minute and adjust REF CAL 
for exact zero beat.  You'll be counting the pulsations in the 
background noise as you come up on zero beat.


I got mine to about 10 seconds per pulsation on 20 MHz back when there 
were sunspots.  That's an accuracy of 0.1 Hz and everything below 20 MHz 
will be at least that good.

[Elecraft] K3 10watt TX Fail

[Bill Davis via Elecraft]

  Ser # 3XXX ... 10w K3.  During normal operations Wed with <1w @14Mhz running 
to my 6m transverer I lost all power output. I assumed a transverter issue. OK, 
I'll drive my 6m PA with the K3 (1.5watts) instead of using my 6m transverter 
(it hears better). 

Yesterday tried a 222 schedule. <1watt 28Mhz  NO output. 

I returned to 6m ... now no output!!! DEAD. Still hears.
 All other transverters are ok since they operate at mw level and are feed from 
tranvserter output on the K3 at 28MHz (driving 144Mhz tranverter for IF use for 
902, 1296, 10GHz.
  Assumption .. 10watt PA board failure ... Turned on the KXP100 to try HF and 
sure enough, no drive, so no power out.
TODAY:  

 I reloaded backup config file using K3 utility .. no difference as expected.
  Ok I'll do a TX calibration ... 1Mw test went beautifully UNTIL50Mhz  NO 
output ... never a bit of power... failed .
  I think I recall, that means the K3 "mother board" ??

  ARGH ... not looking good here :-(

Re: [Elecraft] [K3] Digital "4 flicker 5" help needed

[Don Wilhelm]

Don,

Are you using DATA A mode (AFSK A for RTTY)?
You may have difficulty like that if you are running in SSB mode with 
even a little compression enabled.

DATA Modes automatically turn off compression and TX EQ.
Is your soundcard line out cabled to the K3 Line IN jack?  If you have 
it plugged into the rear panel mic jack you would have excess gain in 
the K3, use LINE IN.


Most users seem to have good luck with the soundcard line out set at 
about 75%, but some soundcards do have a bit more output than others.
You do want to run the soundcard in the upper range to produce a better 
S/N ratio.


You may have to settle for the 3 bars with the 5th flashing.
The flashing 5th bar is the onset of ALC, so you should not drive the 
5th bar solid.

Hello,
 Just checking on this...I am using an interface cable to my computer's
sound card with a stereo plug on one end. I am plugging this in to the
PHONES jack on my KX3. The cable is only using the tip for audio to the
sound card, so essentially the ring (half of the KX3's audio output) is
open. Is this ok for the KX3's audio output circuitry?
 Also, Frank Cady's KX3 book tells me it is ok to use a mono plug to
connect to the PHONES jack. I have not chosen to do this, but wouldn't that
short half of the KX3 output to ground (I suspect there is internal
protection for this)?
 My connections seem to be working fine, but I want to make sure I am
not overstressing something.

Re: [Elecraft] KAT500 without KPA500

[Dick Dievendorff]

Should be fine.  

Use a cable with RCA plugs to connect the K3's KEY OUT connector to one of
the KAT500's PTT RELAY connectors, and another RCA cable the other KAT500
PTT RELAY connector to the amplifier KEY IN.This allows the KAT500 to
interrupt the PA key line during tuning.

When you move to a KPA500, add an additional 15-pin ACC cable from KAT500 to
amp, and don't use the RCA cables, as the key lines are incorporated in the
15-pin cables.

Re: [Elecraft] [KX3] speaker volume - what are my options

I use an inexpensive stereo amp that runs on 12 V.  It is $9 from Amazon. I put 
PowerPoles on the power lead.

I use it with a pair of Pyle speakers ($20). I was hoping to find the old Radio

Re: [Elecraft] KX3 PHONES Jack for Digital Programs

[Nr4c]

I too would use a TRS plug for this. But note that most digital software only 
looks at the tip of the plug.

Re: [Elecraft] KAT500 without KPA500

[Cady, Fred]

Hi George,

There are a couple of pdf files on my website that will help you understand how 
the KPA and KAT operate.  Click on the pdf links at the bottom of the page.

Subject: [Elecraft] KAT500 without KPA500

I am considering purchase of the KAT500 to use with my K3 and an old
AL-80A, with a view to future expansion to the KPA500.  Is there any
reason why an Auxbus cable direct from the K3 to the KAT500 would not
provide the necessary band and frequency information?

Ed,

That should not be a problem.

[Elecraft] KX3 PHONES Jack for Digital Programs

[Ed G]

Hello,
 Just checking on this...I am using an interface cable to my computer's
sound card with a stereo plug on one end. I am plugging this in to the
PHONES jack on my KX3. The cable is only using the tip for audio to the
sound card, so essentially the ring (half of the KX3's audio output) is
open. Is this ok for the KX3's audio output circuitry?
 Also, Frank Cady's KX3 book tells me it is ok to use a mono plug to
connect to the PHONES jack. I have not chosen to do this, but wouldn't that
short half of the KX3 output to ground (I suspect there is internal
protection for this)?
 My connections seem to be working fine, but I want to make sure I am
not overstressing something.

Re: [Elecraft] [KX3] speaker volume - what are my options

[Don Wilhelm]

Kevin,

Get good amplified speakers that do not respond to RF.  I find the 
COMSPKR by West Mountain Radio to fit that need nicely.

Are folks using external powered speakers ? I tried one suggested on the 
reflector or yahoo a few weeks ago, but it sounded horrible. Why is the KX3 
speaker so low?
I checked that the attenuator is off. I checked that RF volume was maxed. I 
checked the antenna was matched with the tuner. The volume is still too low.
Any ideas to make the volume louder, even when at my home QTH (i.e. where power 
is not a challenge)?
