Skip,

I agree with all points you have  made.  

Add to the check list the offset in the K3 Filter setup, verify it is set 
correctly.  On 5 pole filters,, i.e. for SSB the standard 2.7KHz filter, allows 
an offset setting range of 0.00 to +- 9.99KHz (in 10Hz steps).  The same check 
would apply to the 8 pole filters, which should be set to 0.00.  These offsets 
are used by the f/w to set the operating frequency and proper carrier point on 
the filter slopes.

Furthermore, I don’t understand why the NCS isn’t using his RIT, or operating 
in split mode, to “chase” stations he perceives to be “off frequency.”  I think 
back to the past when no one had a digital frequency display to “get within” a 
couple of Hz of the desired frequency.  Maybe he should be required to use a 
Swan 350 for a week or two??

Re: [Elecraft] PX3 Fuse Issue

[Alan Bloom]

The PX3 should draw no more than about 200 mA from the 12V supply.

When power is first applied, there will be some inrush current due to 
the filter capacitors but I'm surprised that's enough to blow a 1A fuse.


Is it a fast-blow type fuse?  Perhaps a slow-blow type would solve the 
problem.

It's quite possible the NCS' radio is 12 Hz off frequency.

That said, "Net Control is *always* on frequency."  ;-)

[Elecraft] The K3/0 Zero as a Remote Frequency knob/PTT for ANY radio with CAT

[Gerry Hull]

Hey Folks,

In my endeavor to find a way to frequency control a Flex using a K3/0, I
tested a couple of solutions.  Nothing worked exactly to my needs.

Then I thought of a very cool idea.   Our friend who developed Skimmer,
VE3NEA, also has a rig-control library called OmniRig.

With a little software glue, I could use OmniRig to build a CATMapper --
not for everything, but for all frequency-related functions and for PTT!!
 It's a little Windows desktop app.

Well, I did it and it works very well.

For you guys trying to do K3/0 + Flex,
- Fire up the Flex with SmartSDR
- Go to SmartSDR-CAT, and ensure you have a COM port for CAT -- and note it.
- Connect your K3/0 to your PC via the USB connector on the side near the
Power connector.
Check your device manager for the COM port number of the K3/0.

Download OmniRig and install it if you don't have it already.
http://www.dxatlas.com/OmniRig/Files/OmniRig.zip
(if you have Windows 10, unblock the app by right-clicking on Zip, choose
Properties and check the Unblock box).  Run the installer.

Download my little app:  https://files.w1ve.com/catmapper.exe
  (if you have Windows 10, unblock the app by right-clicking on exe, choose
Properties and check the Unblock box).   You can run the program from
anywhere.

You press the configure button and configure for your two radio types:
Elecraft K3 for the Mini or a K3, and whatever you want, like SmartSDR for
the Flex.  Make sure to match baud rates, etc.   I recommend a 250ms poll
time.

You should start the app once the K3/0 is connected to the PC, and your
other radio application is connected and running (like SmartSDR-CAT).

This will 100% work with RHR's desktop app -- EVEN WITH a logger like N1MM+
running.  If you want to use with RHR app, Turn off support for K3/0 in the
RHR app -- this replaces it.

This solution will work well with desktop-only virtual radio solutions that
don't have a knob, as long as CAT for the remote radio is exposed locally
on the computer.

The K3/0 is an amazing piece of gear.  I just wish they had not stopped
making it.

Re: [Elecraft] Are external tuners really needed with Chamaeleon antennas?

[Charles Hardt]

Jeff,
I operated Winter Field Day, with my KX3 (Same basic internal tuner as yours) 
at a camp ground down along the Gulf Coast with my club.  I operated with a 
Chameleon 80 meter End Fed Half Wave, working mostly 40 and 20 meters.  The 
antenna was tossed up into a group of pine trees and other green foliage in 
true amateur fashion, severely detuning the antenna.  My KX3 internal antenna 
tuner had no problem tuning.  Elecraft tuners are wide range tuners, typically 
10 to 1.  (Wayne, N6KR, please forgive me for this).  And Wayne, N6KR; 
Co-founder of Elecraft, has written in this very mailing list that he can tune 
Lightly Salted Snow with his KX2!  Jeff you will have no problems with your 
KX2.  Hope to catch you on the air with your KX2/MPAS Lite!

73,
Charlie, N2PKW

I am considering purchasing a Chamaeleon MPAS Lite and from what I gather from

have a kx2 with the internal tuner. I am guessing there is something beyond my 
paygrade as to why this would not be sufficient? If anyone has direct 
experience with these antennas please let me know your experience and what you 
think. Also… I am interested in this particular antenna because I am visually

Re: [Elecraft] Why is my K3 off frequency?

[Grant Youngman]

The other option if you don’t want to go through a REF CAL, is to simply tune 
to the NCS. Use the dial display to get close, and then, like the old days, 
ignore it and tune a few Hz until the NCS sounds right.

Re: [Elecraft] Why is my K3 off frequency?

[Fred Jensen]

Hmmm ... I can just barely hear a 12 Hz difference on a CW note in an 
A/B comparison.  Your NCS must have extraordinary ears to hear that 
small a difference on sideband. Maybe he's just yanking your chain?


First off, 12 Hz at 50 MHz is essentially dead-on and I don't believe 
it's worth your time to mess with it nor do I believe it would ever 
matter.  But, Wayne published a procedure using WWV that will get you 
within 1 Hz at whatever WWV frequency you choose.  It used to be on the 
Elecraft web site but I can't find it now, maybe he'll speak up.  It's 
simple but you must go slowly.  Set the display to WWV's freq at the 1 
Hz display precision, select CONFIG->REF CAL, and adjust the REF CAL 
frequency for exact ZB.  While in REF CAL you'll see a number like
49.379682 in the display [that's what mine says, yours will likely be a 
little different].


When you are very close to ZB, you will hear the beat as a slow rise and 
fall in the noise or the WWV tone.  In my case, two adjacent REF CAL 
steps sort of "straddled" true ZB with the WWV audio tone pulsing about 
one cycle every 3 sec on either one ... ~0.333 Hz.  Get ZB during one of 
the minutes WWV isn't transmitting the audio tone.  Then, when the tone 
comes back, it's easier to hear the beat, and you are assured you're not 
trying to ZB the audio sideband.  Use the highest WWV frequency that you 
have a good S9 signal on.


There is one possible pitfall to beware of:  The 2.5 and 20 MHz WWV TX 
are 2.5 KW and appear to be linear transmitters.  On a panadapter, you 
can see the 100 Hz sub-carrier that carries the IRIG time code, and the 
tone produces the two sidebands you would expect.  The 5, 10, and 15 MHz 
TX appear to be Class C plate modulated and you will see additional 
sidebands at the harmonics of the audio tone frequency.  The second 
harmonic sidebands are only down about 15 dB from the fundamental 
sidebands.  All of the sidebands also show the 100 Hz sub-carrier.  
Using any of those WWV frequencies, you need to be extra careful that 
you're ZB with the carrier and not one of the sidebands.

Re: [Elecraft] Are external tuners really needed with Chamaeleon antennas?

[Jim Rhodes]

Since this is the Elecraft reflector I will go out on a limb and guess you
are using an Elecraft rig with an internal tuner. If so you already have a
wide range tuner in the rig and do not need an external tuner. I am often
amazed at how well my tuners match some really outlandish antennas. Luckily
when in the field I am usually not using a very long feedline so loses in
the coax are kept fairly low.

Jeff-

If you look on Youtube, Thomas Witherspoon K4SWL has a channel (in his name)
and he has a few videos where he is using his KX2 with the Chamaleon
antennas and uses the internal ATU to tune them.  Looks like he is very
responsive to questions so you should be able to get some good feedback from
him.

Re: [Elecraft] Are external tuners really needed with Chamaeleon antennas?

[Tim Tucker]

Since noone has actually answered the specific question...

A few years ago, I was told by the Owner of Chamelon that the CHA
Hybrid-Micro used in that kit as the base & matching unit is 5:1 Unun.  The
manual of the kit has an SWR plot for various types of radiating
elements that can be used:  the vertical, vertical with extension, a length
of wire, etc. Whether or not a tuner is required to obtain an acceptable
SWR is going to depend a lot on what you intend to use for the radiating
element.  If you're planning on using the antenna with one of the vertical
elements on 40m, you're going to need to use the tuner in the KX2...which
will just fine.

The folks who have commented about using just a wire and binding post as
the preferred setup are not taking into considerations the various
operating environments that someone might be in.  I frequent desert and
mountainous areas in SoCal that have no trees or bushes of any meaningful
height.  In those cases, using a man-pack type of vertical (like the
Chameleon) is a very convenient antenna to use with a KX2 or KX3.

Re: [Elecraft] XG50 stock

[SteveL]

Julie,
About a month ago I contacted Elecraft and they did have the XG50 in stock - 
just not reflected on their web page!?.  You might reach out to them to check.

Re: [Elecraft] Why is my K3 off frequency?

[Frank Krozel]

Maybe I am missing the point.  

While you may be off by 12Hz, not sure if I would feel that I want to 
participate in this Net if you are called out for that.

When I was brought into 6 meters I was told this was the Gentlemen's band.  
Most all the nets I participate in are within 100Hz at best.  
Also, I do recall when a current big manufacturer did not set there Bias 
correctly and we (somewhat) lived with it.

I still recall on 6 meters contesting when you ran across a buddy that you had 
not talked to in years, you took the time to chat with him to see how he was.
I hope that still exists!

Sheesh.

Re: [Elecraft] Why is my K3 off frequency?

[John Stengrevics]

Hi Charles,

Maybe you’ve done this, but if not, you should do frequency calibration per the 
manual (p.53 in mine).  

This worked well for me until it didn’t.  I then had to go to a 10 MHz external 
source which works well except that my 2 meter transverter is 600 Hz low (all 
other frequencies are perfect).  Tech support provided an adjustment solution 
for the transverter which  is beyond what I can do.  Will send it back to 
Elecraft when my K4 arrives.

Re: [Elecraft] Why is my K3 off frequency?

[Michael Walker]

If your Net Control station has an accurate enough ear to tell you are 12Hz
off frequency on an SSB net, I would ask him to align it for you.

On 80M, you may be only off frequency by a few hz.

12Hz at 50Mhz is really nothing.  If it concerns you, you will need to
align it with the correct alignment tools and a trip to a repair facility
with a calibrated frequency standard is in order.  If it was me, I wouldn't
worry about it too much.  You can remind your Net controller that that is
what the RIT control, is for on his radio.

If I remember correctly, the K3 accuracy is 5ppm and at 50Mhz that is +/-
250hz at 50Mhz.  It is only 15Hz at 80M.   If my assumption is correct or
PPM, your radio is within Spec.  I'm sure others will correct me if I
am wrong.

Mike

[Elecraft] Why is my K3 off frequency?

[Charles Tropp]

Hi,
Last night my local ham club scheduled their first ever 6Meter Net and
Roundtable for 50.135Mz. I operate USB very rarely, preferring CW for all
of my Contesting and DX work. Last night the net control station advised me
that I was 12Hz too high and that he had to use his RIT control to tune to
me. When I turned on my XIT and transmitted down 12Hz I was right on his
frequency. This was confirmed by other callers as well. I have also heard
this problem mentioned in the past when checking into occasional 75M nets.
Is there an adjustment that I can or should make aside from using my XIT?

Thanks for any assistance you can provide.

[Elecraft] KPA500 OPER/STBY switching?

[F5vjc]

Recently I am seeing an intermittent problem with my KPA500.
Occasionally it will not switch from STBY to Operate, however if I switch
it OFF via the front panel and back on again the problem clears and it will
switch to Operate.

Anyone else see this problem and know the fix, thanks?
