Re: [Elecraft] Sherwood's receiver performance table updated

[John Kramer]

Phil, in reality having a touch screen is not all that bad as you make out. You 
really need
to try it. An advantage is that it reduces the clutter on the front panel of a 
rig, by assigning 
knobs/buttons to the display screen. The one used in the IC-7300 is really good 
- sensitive
to the touch, but not quite as sensitive as some smartphones. The display of 
the 7300 is
a major leap forward from older generation 7600, 7700 rigs. Very clear and 
responsive.
And smear marks on the screen ? absolutely not - I have had my 7300 for 2 weeks 
now,
and have not yet had the need to clean the display - the display is not that 
glossy mirror 
finish like smart phones have. Besides…I prod my touch phone FAR more than I 
touch the 
screen of my 7300, and I have no problem with finger marks on my phone….maybe 
once a 
month I might clean my phone with a lint cloth…no big deal. Perhaps I might 
clean my 7300
display once every 3 months at this rate…no biggie

screen for a radio that already has uses for actual dials and buttons seems to 
me to be unnecessary.  And, that does not even consider the fact that touch 
screens need to be periodically cleaned from oily finger prints.

Of course, this is indeed an unsolicited opinion and comment.

Jim, you don’t have to use your finger, you can use a stylus if you are 
pedantic about accuracy :)
and if you are a few hertz off, it just takes a gentle nudge of the VFO to get 
it spot on.

Re: [Elecraft] Sherwood's receiver performance table updated

[John Kramer]

I own Elecraft, Flex and for the past few weeks an IC-7300. Yes, Jim, it is a 
fine radio,
I have personally experienced this and own a KX3 and 3 Flex rigs to compare it 
with.
And, for what it costs, it is a damn fine rig. I don’t know of any other rig 
currently available
that is such good value for money. 
Perhaps the K3S would be better in terms of performance…but for the money, the 
IC-7300 is very capable, and has a brilliant UI.

How do we KNOW that it's a "fine radio?" I haven't seen a review by ARRL or 
RSGB. We have only Rob's measurements of the RECEIVER.

[Elecraft] KX3 anomaly, birdie transmitted

[John Kramer]

I have a newish KX3 factory built. I just noticed something odd with my KX3. I 
usually use my
KX3 for portable use so its not often in the shack, but yesterday I had my Flex 
radio’s 
connected to my SteppIR beam on 15, and I hooked up my KX3 to an EFHW wire 
which is about 100 ft away from my SteppIR. 
With both the Flex and the KX3 in receive mode on 15 meters, I noticed on the 
Panafall
display of my Flex rig, that my KX3 is transmitting a birdie about 700 Hz below 
it’s RX frequency. 
When I turn the dial on the KX3 I can see it moving up and down the band on my 
Flex radio. It is quite
strong, about 70 dBm.

Is this normal ? for the KX3 to put out a “birdie” 700 hertz below it’s 
displayed RX frequency ?

Thanks - yes, when I disconnected the EFHW wire antenna going to the KX3, then 
the birdie
that I could hear on my Flex radio disappeared. So it’s getting out through the 
antenna that
the KX3 is using

Re: [Elecraft] 75m

[John Kramer]

The ham population is merely a representation of society. It is not better or 
worse than any other group.
It is a chunk of about (in the case of USA) 400 000 (I think) people grouped 
together out of the general
population. 

The ham fraternity was never, and will never be any better OR worse than any 
other group - Golf club, cycling
club, running club, country club, 4X4 club, Harley club, yes... even church 
group  etc etc etc. 

If the ham fraternity 40 years ago was better behaved….then that is only 
because the general population 
was better behaved 40 years ago.

Like any other chunk out of the population, you get smart people, dumb people, 
polite people, rude people, 
rich folks, poor folks, thrifty folks, generous folks…..so yes, you will get 
some idiots that are hams….but
then there are plenty of good folk too. You are merely looking at a group of 
people that is representative
of current day society. So, if there is a group that offends you…simply spin 
the VFO dial to a different
frequency or band….simple. Don’t get hung up on some of the idiots out there - 
you will always get some
idiots in society….always have…always will.

Many of the same colorful characters on 75m make regular appearances on 40m &

Re: [Elecraft] New release of Win4K3Suite...set your clocks!;

[John Kramer]

Just my personal opinion with experience of both

There is not much difference between the paid version and the latest free 
version of HRD,

Both compliment each other and work together - W4K3 works with HRD, so I would 
go with 
the latest free version of HRD and ALSO the W4K3. They do overlap on some 
functions,
where they can do the same thing. IMHO the W4K3 is excellent for the PanaFall 
display of
the band, and is also excellent for getting to menu functions quickly, and 
everything you
need is one mouse click on the display. HRD is good for it’s logging program, 
digital modes
rotor control, cluster - point and click on a DX spot and instant QSY etc etc

They both talk to each other so it would be best to get both, but to save on 
costs get the free
version of HRD.

Re: [Elecraft] [KX3] Fwd: Yaesu 817ND vs Elecraft KX3 Differences for Portable Use

[John Kramer]

Interesting read Wayne. So to sum up, the only areas the FT-817 beats the KX3 
is that
it has a better speaker and you can change the colour of the backlit display :)

That would be easy - put a better speaker in the KX3, and give it an adjustable 
blue/green or
amber backlit display…and then the FT-817 will have nothing over and above the 
KX3 :)

Come to think of it…the KX3 with a blue backlit display would look cool

Re: [Elecraft] [KX3] Yaesu 817ND vs Elecraft KX3 Differences for Portable Use

[John Kramer]

I have the three - FT-817ND, IC-703 plus and the KX3. I would say the IC-703 
plus presents more of
a formidable competition to the KX3 than the FT-817.
The IC-703 gives 10 watts, built-in ATU, big display (similar to the KX3) 
features where the FT-817
falls short. 
When I go outdoors, it is usually a toss-up between the KX3 and the IC-703 
plus. If the operating
environment is a little rough, then I would take the IC-703 - I don’t want to 
hurt my KX3 :) but
under all other circumstances, the KX3 is my choice. My FT-817 never cracks the 
nod, to come
along on outdoor adventures - not enough power when the bands are in bad shape, 
no built in ATU, 
and that small display that you have to squint at….nope.

Re: [Elecraft] KX3 power supply

[John Kramer]

Don

Thanks for the reply. I have thought long about it, and decided I would rather 
not risk damaging
my KX3 for the sake of a cheap PSU. I live too far away from the factory to 
risk damaging
the KX3 - it cost me $ 450.00 just to ship my new KX3 to me in June.

I will leave the cheap eBay PSU for some other project, or the trash. I have 
plenty of other 
regulated, stable PSU’s that supply the correct voltage, so I will continue 
using them.

I would never forgive myself if I damaged my KX3 by using a cheap eBay PSU.

Thanks for all the replies

John,

I would suggest that you put a diode in series with that supply - rated
at 5 amps.  That will reduce the voltage by the amount of the diode drop.
Running the KX3 (or any other device) above the specified maximum
voltage is done at your own peril - it may work, but it taxes the
regulators and other devices.

[Elecraft] KX3 power supply

[John Kramer]

Someone on this reflector suggested a power supply off eBay, that could be used 
with the KX3 about 2 months ago. It is intended for Toshiba laptops. So I 
bought one, 
this is the one…

http://www.ebay.com/itm/15V-5A-AC-Adapter-Charger-Power-Supply-For-Toshiba-Tecra-A6-A7-A8-A9-A10-Laptop-/381356162365?hash=item58ca993d3d:g:Yk0AAOSwMmBVxX22
 


It terminates in the right plug for the KX3 and is rated at 15 volts at max 5 
amps, and only sells 
for $ 7.79 including free shipping from Hong Kong.
Anyway, it is cheap as chips so I bought one, and it arrived today. I hooked up 
to a volt meter
and see it is 15.4 volts. I know it is better for TX IMD to have higher voltage 
supplied to the 
KX3 rather than a voltage too low, but I am concerned that 15.4 volts may be 
too much
for the KX3. I see in the KX3 manual specs, that recommended supply voltage is 
8 - 15 volts.
I would hate to hurt my KX3 with over voltage……anyone know if there would be 
any short
or long term problems with running 15.4 volts to the KX3 ? It is just slightly 
above the 
maximum recommended supply voltage

Re: [Elecraft] KX3 power supply

[John Kramer]

Thanks for the info Bob, and it’s reassuring to see that the KX3 has protection 
for 
over voltage.
One caveat with this PSU - I just tried to insert the DC plug from this  PSU to 
the KX3, 
and I see it is too large for the KX3. Not a big deal, I will just cut it off 
and fit the correct
size DC plug

Re: [Elecraft] K5P Palmyra Dxpedition on the air with Elecraft rigs

[John Kramer]

I’m really happy they took omni directional vertical antennas along.
For most DXpeditions that use directional antennas, they never beam
to my direction (understandably, as we are thin on the ground in Africa).

We at last have a fighting chance to get in the log, and it levels the playing
field, with their vertical antennas on all bands.

I have them on 3 band slots thus far

Re: [Elecraft] 30% discount on KE7X books at Lulu 12/31 only

[John Kramer]

Rats !  I tried to purchase the eBook version of the KX3 book. I live in 
Africa, and shipping more than doubles the cost of the printed book,
so I wanted to buy and download the PDF version.

I entered your code, but it tells me that the discount is only applicable to 
the printed version. I was hoping the holiday spirit
could have been extended to the PDF version….after all it is cheaper to produce 
and distribute than a printed version.

Re: [Elecraft] OT: B & W antenna

[John Kramer]

I would not touch any antenna that uses a resistor. That is what a dummy load is
after all - great SWR but the losses are huge.

I built a T2FD when I was newly licensed back in 1984 (when I didn’t know any 
better),
from an article in Practical Wireless. I used the specified resistor and built 
it according to spec,
and put it on top of a 220 ft  building, raised 20 ft above the building. Any 
antenna
should have worked really well at this height being totally up in the clear. 
The SWR
was great across all the bands, but I was very disappointed in it’s 
performance. 
I have learnt a lot since then…

BTW nothing wrong with OCFD antennas, they work well on their harmonic 
frequencies as a multi band antenna, provided they are installed properly, and 
a good CMC is used in the
feedline. No, not an ugly Balun which might give you 1000 - 1500 ohms choking 
impedance
if you’re lucky, but a proper CMC with more than 12 000 ohms choking impedance.

I would rather hang a good OCFD with a quality 4:1 Balun at the feed point, and 
a 
quality CMC choke for 80 - 10 just before the coax enters the house, rather 
than fiddle with
8 dipoles yuck…

Better yet, would be to use an EFHW 80-10 1K built by www.myantennas.com

Re: [Elecraft] Advice on First HF Antenna

[John Kramer]

I can suggest an antenna by www.myantennas.com  Look for their antenna
called an  EFHW 80-10. It will take 1 KW, and has a low SWR on all bands
80/40/30/20/17/15/12/10 bands. It is a half wave design, that I have had 
tremendous success with as a second antenna to my SteppIR beams. 
It is easy and quick to get up, and will serve you well until such time that you
decide whether to put up a tower and beam. It will also serve well as a portable
antenna. I have done comparisons to numerous OCFD, Gap Titan vertical,
G5RV, ZS6BKW, loops and other wire antennas, and in most cases it 
outperformed all of them.

Re: [Elecraft] RFI in audio chain

[John Kramer]

Jan

The easiest, quickest and cheapest method is to wind yourself an “ugly balun” 
in your coax cable line. 
It must be located OUTSIDE your shack to choke the common mode currents from 
entering the shack.
Wind about 15 - 20 turns of your coax on a 6” PVC pipe. This will give you 
about 2500 ohms choking
impedance. 

If there is still RFI getting in the shack, then purchase a commercial choke 
either from
http://www.balundesigns.com/model-1115d-max-choking-1-1-balun-1-54-mhz-5kw/  
this will provide about 10 - 12 000 ohms of choking impedance, or buy one from

http://myantennas.com/wp/product/cmc-130-3k/
This one will give from 12 000 - 15 000 ohms of choking impedance.

These common mode chokes merely get plugged inline in your coax cable. Always 
better to locate
them outside the shack

I have a problem that appears to be changing, but I could use some help.  The 
problem is RFI in the audio input (microphone input) when I use my vertical 
antenna on 40 meters.  Here is a rundown of what has happened:

I have a 67-foot elevated vertical that I can use on 80 and 40, and it works 
fine on CW.  However, on SSB, both bands, there clearly is feedback; there is 
no feedback on the other bands where I use a C3 yagi.  Initially, the feedback 
was so bad that the rig would go into oscillation, and I had to turn the amp to 
standby.

I recently purchased the new KSYN3A and decided to install it.  I replaced the 
K3 with my IC-730 backup, using the hand microphone that came with the 730.  
The 730 did not have any RFI.  I finished the modification and returned the K3 
as the operating rig.  Now, the RFI on 40 seems to have diminished 
substantially or disappeared, but it still happens on 75/80.  However, it seems 
to be much less there as well.  I do not suspect that the KSYN3A had anything 
to do with this, but perhaps I tightened connections better when I returned the 
rig to service.  I also redid some ground connections.

The microphone for the K3 is an Audio-Technica that works well everywhere else. 
 It has a long cord, though.  I put a few toroids on the cord near the 
microphone connector and that has possibly reduced RFI a little, but it is 
still there.

Is there a possibility that a bypass capacitor is bad, or has someone else had 
the problem and solved it externally to the K3? For instance, has anyone found 
that a long string of ferrite beads has cured this problem?

Despite decades of operating, I am hardly a troubleshooting hotshot, and I 
would appreciate guidance.

Thank you,

Jan, KX2A

Re: [Elecraft] P3 vs SDR-IQ

[John Kramer]

Dale

See, there are limitations to both tracking and fixed modes. 
1. Yes, in tracking mode you don’t lose your waterfall - BUT you lose your
averaging when you tune.
2. If you want averaging to stay on all the time - tuning or not, then you can
choose “fixed”, but then the limitation with that mode, is that your VFO
filter moves along the display, drops off the edge, and refreshes the 
waterfall history.

I would like to see a combination of both, which is the way it works with 
Flex and PSDR - VFO receive filter remains centred, and does not move off to 
one side….and at the same time, while tuning, averaging remains on all
the time.

Yes, I have tried the MKR option, but find it quite fiddly, lots of knob 
pushing to 
achieve something, so I generally don’t use it.

It's true that in Fixed tune mode when you cross the boundary at either

Regarding your PX3, have you tried positioning MKR A on the signal of
interest, and then tapping the 'SELECT' knob on the PX3 to instantly take
you there? By doing that, you won't lose track of that signal. If you
decide you want to go back, push and hold the 'SELECT' knob to return to
your previous frequency.

snipped / And also, in Fixed mode, when
 it reaches the
 end of the display, it jumps back to the middle, and refreshes the
 waterfall - so any waterfall
 history that you had, is lost :(
 I have never used a Flex 6000 series radio, but I have been using, and
 still have the 5000A,
 3000 and 1500. The system they use works just the way I want it - the RX
 filter remains centred
 in the display, and when you tune, the averaging remains on at all times.

Re: [Elecraft] P3 vs SDR-IQ

[John Kramer]

Phil

So….you’re okay using “fixed tune” where your VFO window moves off-centre, and 
heads off
towards the edge of the screen - at this point you can’t see whats ahead of you 
because you’re
near the edge of the pan adapter. If you go any further, you fall off the edge, 
and it plonks you back 
in the centre, the waterfall refreshes, and you lose your waterfall history. 
That’s okay ?

Wouldn’t it be better if your VFO window remained centred in the pan adapter, 
even if you tuned up
the band ? so you can see equally whats going on above and below your frequency 
? Yes, you can
do that in tracking mode…but then we get back to the issue of it resetting and 
removing the
averaging feature.
If you haven’t tried an SDR radio that can do both - “fixed and “tracking at 
the same time, perhaps
you should try, and see what you’re missing out on. If the clever guys at 
Elecraft can come up with
a firmware update that will allow you to do both…simultaneously, would you 
choose to rather have your
VFO window jump off the edge every time you get to the end, as in “fixed tune” 
? Perhaps they could 
give us a menu choice of all three options - “fixed tune”, “tracking” and 
“fixed tracking”. Would you stifle 
the opportunity of having this menu choice ?

I better stop, I’m starting to feel like I’m repeating myself :-) Have a good

I agree with Joe. My usage of the P3 and the PX3 is 100% fixed-tune mode, and I

I've never really found a situation where Tracking mode is helpful, but maybe 
I'm missing something.

John,

The P3 and PX3 use entirely different interfaces to the radio. The P3 taps into 
the K3/K3S 8.2 MHz I.F., while the PX3 uses a baseband I/Q signal from the KX3. 
While both methods provide the basic benefits of a panadapter, the P3's 
implementation provides higher performance, using more expensive hardware, and 
is priced accordingly.

The P3 is incredibly smooth in its tuning and presentation, and the unit is 
widely regarded as one of best panadapters available. Averaging, fixed-tune 
mode, noise blanking, peak detection and its many other features are all free 
of any sort of tuning noise or artifacts. 

If you're in fixed-tune mode, where the VFO/filter cursor moves across the 
screen, averaging information is preserved. There is no increase in the noise 
floor, no matter how fast you tune.

In tracking mode, where the VFO/filter cursor stays fixed at the center of 
the screen, averaging information is reset when you tune. This has always been 
the case, but I'll mention this to our panadapter design staff and see if it 
might be possible to preserve the averaging data in tracking mode.

In any case, I hope you can observe a P3 in action sometime.

Thanks for that info, I would like to try that out - I must have missed that in

One minor note:  There are three different P3 and PX3 fix mode tuning defaults 
you can select in the menu for when you tune past the edge of the display: 
slide, 1/2 screen and full screen jump.

I generally prefer the slide mode as it is less jarring and drags the window 
incrementally in the direction you are tuning.

 Hello John,

 So….you’re okay using “fixed tune� where your VFO window moves
 off-centre, and heads off
 towards the edge of the screen - at this point you can’t see whats ahead
 of you because you’re
 near the edge of the pan adapter. If you go any further, you fall off the
 edge, and it plonks you back
 in the centre, the waterfall refreshes, and you lose your waterfall
 history. That’s okay ?

Re: [Elecraft] [KX3] PX3 display not sensitive

[John Kramer]

I bought a new KX3 and PX3 factory built, 3 weeks ago. It is a great pair, but 
there are several 
annoying things. The one thing that I have issue with is the very poor 
“sensitivity” of the PX3.
I have 59 plus 10 signals on my KX3, however, on the PX3 waterfall the trace is 
very faint and
indistinct. This is on a signal more than 20db above the noise floor !!!
I really hate to have to compare, but on my Flex radio’s, you can see signals 
on the waterfall display 
that you can barely hear in the receiver. And when signals are reasonably 
strong, you can analyse 
the signal to a good degree - you can see if the transmitting station is 
splattering, overdriving etc
With the PX3 the sensitivity is quite poor - with a strong signal you can 
barely see and analyse 
the incoming audio. I have tried a number of settings, adjusting contrast etc 
but I can’t seem
to improve it, and guess it’s inherent in the firmware.
Am I missing something ? or can it be improved in a future firmware update ?

Re: [Elecraft] [KX3] PX3 display not sensitive

[John Kramer]

Matt 

Thanks for your response, really appreciate it.

1. Yes, the RX IQ is enabled - I think if it wasn’t enabled I wouldn’t see 
anything on the PX3.
It is working normally, it’s just that the trace left on the waterfall is 
extremely faint for a signal
that is 20 - 30 db above the noise floor. The Flex and PSDR will show a clear 
trace at close 
to the noise level or just a few db above it. Maybe I am expecting too much 
from what is
essentially a portable radio and portable panadapter.
2. Yes, I have fiddled with the REF and SCALE, but can’t improve on the factory 
settings. 
I can bring up the sensitivity, but that introduces noise on the waterfall, and 
the wanted signal
is now buried in the noise on the waterfall.
3. No, I haven’t tried the side nulling procedure. Having bought the KX3 and 
PX3 factory built,
I would have thought it would have been done prior to shipping ? But I don’t 
see images or
anything like that which would point to this being a problem. It appears pretty 
well
balanced. I don’t have an XG3 to calibrate, but might try using the built-in 
generator in the PX3

Thanks again for the reply, and have a good weekend

That doesn't sound normal. Three things to check:
- in the KX3, do you have the RX I/Q set to Enabled
- on page 16 of the PX3 manual, check the REF and SCALE settings
- have you done the side and nulling procedure on page 26? Maybe the gain 
settings there are not sane.

Re: [Elecraft] Is there a good reason to buy a K3S instead of a used K3 ?

[John Kramer]

My uneducated guess, is that on paper there will be a big difference….but in 
the real world, listening on air
and trying to compare the difference, it would be hard to tell them apart.
We (and I include myself in this) are too paranoid about every db or dBm that 
is reported in a test. I guess it’s
the same as the power guys - trying to get every watt out of their radio - they 
complain that their rig is only
putting out 95 watts, and they want to turn it up to 100 watts. To make a 
noticeable difference they would 
need at least 3 db or a doubling of power.

I can’t remember if it was Eric or Wayne that said - getting your rig to the 
top of the Sherwood list is really 
only a great accomplishment for the engineers and designers, because all the 
rigs in the top 10 will hear equally well
for the guys that actually use them on air.

 The opportunities I have are limited antennas currently and we may yet move

[Elecraft] Elecraft user suggestions

[John Kramer]

Hi all

Two weeks ago I bought a new factory assembled KX3 and PX3. Serial numbers 
#7972 and # 1307 respectively,
which I will be using for the great outdoors.

My main radios in the shack are Flex radio’s. I have been playing with the KX3 
and PX3 and have a number of 
suggestions for firmware and hardware improvements. Where do I send these 
suggestions to, for Eric and Wayne 
to see - I don’t want to bug them on their private email.
