Re: [Elecraft] KX2 added to Sherwood's list

[Wayne Burdick]

We found the problem; turns out to be in the setup command to the DSP, not in 
the DSP itself. With any luck we'll have it fixed this week in both rigs.

Re: [Elecraft] KX2 added to Sherwood's list

The problem described below also exists in KX3,

That is why I always  adjust bandwidth to 50,150,250, 350 etc Hz.

standardized 500-Hz filter bandwidth (or any even bandwidth value). 
Note:  Both the League and I only publish the LOWER of the two

95 dB and the high side is 90 dB. Both the League and I publish the 
lower worse-case 90 dB number. In the case of the KX2, I couldn’t pick 
the lower of the two readings since no measurement is possible when 
using the standard 500-Hz filter.


Since the 2-kHz dynamic range value could not be made with the 
standard filter bandwidth at 2 kHz, but could be made at a 3-kHz 
signal spacing, I published that data.  It may be of interest that the 
2-kHz dynamic range number with the non-standard 450-Hz bandwidth was 
only 1 dB worse than the 3-kHz value.  The point of listing the 3-kHz 
value, or any other radio with a non-2 kHz listing is to point out the 
radio has a limitation in its filter performance.


My long form report on the KX2, available in PDF format, goes into 
detail about this issue, and has data on the two radios I tested, 
listed by serial number.


At this point, Elecraft does not know why the KX2 behaves this way, or 
whether there is a possible firmware fix.

[w4sc]

A ”temporary” FW fix may be to make the BW settings reside on 50Hz boundary’s 
every 100Hz  i.e. 150,250,,,2150,,, as adjusted. I doubt if the ‘tween settings 
“00” would be missed.

Re: [Elecraft] KX2 added to Sherwood's list

[Wayne Burdick]

The cause of this is likely to be straightforward. One of our software 
engineers is looking into it. Once we have the fix in place, we hope to get a 
KX2 to Rob for retesting.

A temporary workaround (if needed due to QRM) is to use 450 instead of 500 Hz, 
etc.

[Elecraft] KX2 added to Sherwood's list

[John Reilly]

John, N0TA, forwarded this question to me about why I listed the KX2 
close-in dynamic range at 3 kHz rather than the more typical 2 kHz. 
Some radios have limitations that make a measurement at 2-kHz impossible 
or invalid.  If a valid measurement cannot be made at 2 kHz, then it is 
made at some wider spacing, such as 3, 4 or 5 kHz.  Typically if a 
measurement cannot be made at 2 kHz, it is because of filter leakage. 
When a test is made at 2-KHz, for example, the third-order 
intermodulation products are 2-kHz below the lower frequency test tone 
and 2-kHz above the higher frequency test tone.  If the radio cannot 
reject the test tone that is 2-kHz away, then it is impossible to 
measure the third-order distortion product.


In the case of the KX2, I could measure the low side distortion product 
at 2 kHz with no problem using the standard 500-Hz filter bandwidth.  On 
the other hand, when measuring the distortion product on the high side, 
the filter in the KX2 does not reject the test tone that is 2 kHz away. 
Two different KX2 radios were tested, and both showed this identical 
anomaly.  If one reads the ARRL report on the KX2, you will see that the 
reviewer mentioned the filter leakage when tuned above a strong signal.


Here are the odd details on the KX2 filter leakage.  If the filter 
bandwidth is 500, 400, 300, 200 or 100 Hz, filter leakage makes the 
measurement at 2 kHz impossible.  On the other hand, if the filter 
bandwidth is 550, 450, 350, 250, 150 or 50 Hz, then the measurement can 
be made.  The League chose to publish a 2-kHz dynamic range in QST even 
though the measurement cannot be made on the high side with the 
standardized 500-Hz filter bandwidth (or any even bandwidth value). 
Note:  Both the League and I only publish the LOWER of the two 
measurements.  Let’s say the low side dynamic range of some radio is 95 
dB and the high side is 90 dB.  Both the League and I publish the lower 
worse-case 90 dB number. In the case of the KX2, I couldn’t pick the 
lower of the two readings since no measurement is possible when using 
the standard 500-Hz filter.

filter bandwidth at 2 kHz, but could be made at a 3-kHz signal spacing, 
I published that data.  It may be of interest that the 2-kHz dynamic

Re: [Elecraft] KX2 added to Sherwood's list

[Luke via Elecraft]

Just a couple weeks ago I took my KX2 out to a local park during my lunch break 
and made a contact using it as a HT, using the MFJ-1820T and a 12' 
counterpoise. From setting it up and makinge a quick 20m SSB contact took me 
all of about 3 minutes.
Yeah, it's not the preferred technique, but it worked :-)

Yes, and I have used a whip for pedestrian with success.  A 20 meter Maldol

But that is our hobby, dependent on conditions.  Run 1500 watts in poor condx

[Elecraft] KX2 added to Sherwood's list

[John AE5X]

I notice that the KX2's narrow dynamic range is tested at a 3 kHz bandwidth. 
Other radios on Sherwood's list are measured at either 2, 3 and 5 kHz. Doesn't 
this make direct comparison between various radios (and list order - since they 
are listed by dynamic range order) invalid?

Of course a great antenna makes a huge difference. But I do enjoy the ultimate 
challenge provided by compromise antennas, and sometimes a whip is all you have 
time to deploy.

Re: [Elecraft] KX2 added to Sherwood's list

[Chris Tate - N6WM]

Wayne,

After I used my KX2 using a KXB2 on the beach on the Windward side of Oahu, 
interfaced with a low end laptop on battery power and connected to a half wave 
dipole, a half wave from the surf, and hearing the quiet noise floor, q5 sigs 
and being heard and spotted all over north America and working into n NA,  the 
EU and Asia qrp???

This is an awesome little go anywhere rig.  

But I do think that a big part of that formula was that nice wire at the beach 
with an infinite GP.. and not sure the whip would produce that result..  but 
probably could do pretty well in the same environment none the less.

Grab and go rig.. best one around.

~Chris
N6WM

Re: [Elecraft] KX2 added to Sherwood's list

[Dave Fugleberg]

Not 'hand held', but I did use the MFJ telescoping whip for 20m with a
right angle BNC adapter with the KX2 next to me on a park bench a couple
weeks ago and worked AZ from MN. With the internal battery, that whip, and
some wire for a counterpoise, it takes almost no time to set up.

Re: [Elecraft] KX2 added to Sherwood's list ..

[Mike Morrow]

I was surprised that the KX2 ranked **18** positions BELOW the KX3.  That shows 
the KX3 is a really remarkable world-class achievement.   Plus, at least an 
early system schematic (excluding the KX3-2M two-meter module and PX3) is 
available.  That leaves the KXBC3 battery/RTC as the only mediocre component in 
the system.

I decided not to buy a KX2 until and unless minimal technical information 
(schematic) was available.  It has become obvious that such is purposely and 
likely permanently withheld from most customers...a really remarkable and 
negative non-traditional policy for ham gear...especially gear directed to the 
QRP community.

Operating HF hand-held has not had any valuable application since the WWII 
SCR-536/BC-611 handie-talkie.  I like to operate my QRP rigs, especially high 
performance Elecraft units, with antennas that complement the quality of the 
radio.  No Elecraft rig deserves the degradation of a HF telescoping antenna.  
That's pure gimmickry, IMHO  :-)

73,
Mike / KK5F

I haven’t tried hand-held with a whip antenna yet but only because I figured
it would be a bit awkward trying to operate the paddles.
