[Elecraft] Heil Proset Headphones

[Irwin Darack]

I am looking at picking up a second Headset Mic - DX chasing and
contesting.

What is the difference between the Heil Proset PS 6 and the Heil Proset K3
headsets for the K3 & K3S radios?

Happy New Year

Thanks, Irwin KD3TB

Re: [Elecraft] Heil Proset Headphones

[Don Wilhelm]

Irwin,

The main difference is in the microphone element.
The PS-6 has the Heil HC-6 element which is a wide range dynamic element 
which has a relatively low output.
The ProSet-K2/K3 uses an electret element which has a high output level 
- it needs to have bias turned on.


The K3/K3S is quite capable of handling either of them.

73,
Don W3FPR

Re: [Elecraft] W1

[Bob Novas]

Ed - What are you putting the output power to --  a dummy load or an
antenna?  Do you have the KAT internal antenna tuner?  If there is an SWR on
the antenna line that the KAT is tuning out for the transceiver, then the W1
will read forward power and reverse power on the antenna line whereas the K3
will read output power.  If you subtract the W1's reverse power reading from
the W1's forward power reading, does that compare to the K3's power reading?
Try reading the two power meters into a good dummy load. Then the K3 reading
and the W1 forward reading should be equal. Bob - W3DK

Re: [Elecraft] W1

[John Oppenheimer]

I performed some additional research, Johnny, VR2XMC, measured TP1 V at
4.82 back in December 2006. Maybe the 4.5 is a typo and should be 4.8:

[Elecraft] W1

[Ed Lambert]

It is probably necessary to restate my question with more precision.

1.   I have calibrated the K3s using Elecraft K3 Utility

2.   I have carefully calibrated the W1 using the DDM method with a good
quality DDM.

3.   Comparing the results, I see that the W1 consistently calculates
power about 1 dB higher than the K3s. Statistically, I would have expected
them to be closer. From the W1 specifications, and not knowing the K3s power
accuracy specifications, it seems that, possibly, the K3s is displaying
about 3 sigma low and the W1 3 sigma high, which is unlikely.

4.   The question: Should the K3s be calibrated from the W1 or should
the W1 be calibrated from the K3s?

(There could be a detailed, separate discussion of the meaning of "average"
power and "PEP" as used in the W1 programming reference. It is my belief
that the two should be the same thing if using a cw signal and the FCC
definition of "PEP". It would be interesting to know what is going on in the
K3s transmitter gain calibration process. It seems like there is an internal
power measurement process and the gain is being set against that. Does that
internal measurement process have accuracy equivalent to the W1 or vice
versa?)

Re: [Elecraft] W1

[John Oppenheimer]

Hi Ed.

The W1 DC voltage calibration resulted with incorrect reading with my
W1. My hunch is that components have changed since Elecraft established
the TP1 DC calibration voltage almost a decade ago.

I have a KX3F with unchanged factory power calibration. Based on
comments from Wayne, the KX3 is calibrated at 7.0 watts.

My W1 TP1 voltage is 4.812 using a Fluke 87V

Setting up a test bench with KX3 -> W1 -> DL1

Using W1 Utility to display W1 power:
http://www.elecraft.com/software/W1/elecraft_w1_software.htm

TP1 V = 4.812
KX3 power = 7.0 W
W1 power = 7.02
DL1 V = 12.91 = 6.93 watts

The W1 20 dB directional coupler does absorb power, at 7 watts, the
directional coupler will absorb 0.07 watts. Adding 0.07 to the DL1
measurements equals 7.00 watts.

Re: [Elecraft] Elecraft gear relative IMD

[Kevin Stover]

Two different animals.
Harmonics and spurs are regulated by the FCC to be at least -43dB down 
on HF and -60dB down on 6 meters.

The K3(s) meets those specs easily as evidenced by a couple of QST reviews.
IMD is not regulated I think because most hams don't have the test 
equipment to pull it off accurately.


All of this IMD hullabaloo would quickly go away if the manufacturers 
would switch from 12V finals to 50V finals or used pre-distortion of 
some sort. How much will Ham's pay to clean up the IMD problem when the 
FCC doesn't regulate it?

Hi,

Here is the spectrum out of the USB codec with a -73dBm carrier from the
XG3:

The K3S setting is USB with a passband of 300 to 2400Hz. I left the LINE OUT

Windows mixer (Win7).

Re: [Elecraft] KIO3B Audio Spec

[ab2tc]

Hi again,  

BTW, some people have been complaining about 60Hz hum in the audio. I zoomed
in one the low end:

http://ab2tc.com/k3s_usb_lows.png

There is absolutely no sign of 60, 120 or 180Hz in this spectrum. I have
also listened to the signal with good headphones and hear no trace of hum.

Re: [Elecraft] New K3S can't/won't talk to the K3 Utility

[Don Wilhelm]

John,

You first have to click on the "Copy New Files From Elecraft" button to 
load the files into your computer.
After they download, you should see the information in the "Firmware 
Revisions" section.  You should see the list of what is installed in 
your K3S as well as what is Available.  If your firmware is at a lower 
level that what is available, you can click either the "Send All 
Firmware to K3" button or the "Send All New Firmware to K3" button.  The 
firmware load should proceed automatically.


Yes, if you cannot connect to the Elecraft website, you will not be able 
to get the firmware files into your computer.


Click on the Configuration tab and see if you can save your current 
configuration.

[Elecraft] FW: W1

[Ed Lambert]

John,

Thank you for your response.
My original K3s test setup was per the manual: good quality dummy load (not
the DL1 because of its 20 watt upper limit) with the ATU off. My high
quality dummy load does not have a test point.
After reading your results, I decided to take the DL1 as my "truth model". I
found that the W1 display was 0.8 dB high and the K3s power display was 0.9
dB low. Each one was at the opposite end of the error budget. (sort of like
winning the "losers" lottery).
So, I set up the W1 to match the DL1 up to 20 watts and, surprise, the W1 TP
voltage is now 4.87 volts.
I don't have the W1 software and cabling installed yet. At that time I can
fine tune all of this.
It seems as though a consensus is building that the W1 manual specification
of 4.5 volts is no longer correct, unless there is something "off" with the
W1 internal algorithm.
Good stuff. Thank you everyone for your comments and help.

Hi Ed.

The W1 DC voltage calibration resulted with incorrect reading with my W1. My
hunch is that components have changed since Elecraft established the TP1 DC
calibration voltage almost a decade ago.

I have a KX3F with unchanged factory power calibration. Based on comments
from Wayne, the KX3 is calibrated at 7.0 watts.

My W1 TP1 voltage is 4.812 using a Fluke 87V

Setting up a test bench with KX3 -> W1 -> DL1

Using W1 Utility to display W1 power:
http://www.elecraft.com/software/W1/elecraft_w1_software.htm

TP1 V = 4.812
KX3 power = 7.0 W
W1 power = 7.02
DL1 V = 12.91 = 6.93 watts

The W1 20 dB directional coupler does absorb power, at 7 watts, the
directional coupler will absorb 0.07 watts. Adding 0.07 to the DL1
measurements equals 7.00 watts.

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] KIO3B Audio Spec

[Bob McGraw - K4TAX]

In Knut's plot with the 1 kHz peak, the 2nd harmonic and 3rd harmonic 
are clearly visible.  In the one with the low end, I agree, no 60 Hz, 
120 Hz or 180 Hz is seen.   I measured my K3S with the radio connected 
to the computer via the USB port.  No 60 Hz, 120 Hz or 180 Hz signal 
observed.


I suspect if anyone is experiencing "hum" they best look for a ground 
loop which likely exists as there is a difference in potential between 
different pieces of equipment.

Re: [Elecraft] [Elecraft_K3] Re: Heil Proset Headphones

[w7aqk]

The Elecraft Pro Set is essentially a duplicate of the Heil IC Pro Set.  The 
IC version of the Heil was, as I understand it, introduced as a suggested 
model for Icom radios (thus the "IC" designation), and has an electret 
cartridge.  Electrets apparently work quite well with Icom gear, and they 
work very well with Elecraft gear.  As most already probably know, many of 
us who have Elecraft K3's and K2's have opted for the Yamaha CM500, which 
also has an electret cartridge, and is considerably cheaper than Heil's 
models.  All the bias requirements for electrets are handled through menu 
options on the K3, so it is very simple to use them.  It also plugs directly 
into the back of the K3, so you don't need any of the adapters.  The K2 will 
also provide the necessary bias, but you have to change a connection 
internally.  I personally don't find any particular benefit to either the 
Heil or the Elecraft models, and I have both.  The Yamaha works great.

Irwin,

The main difference is in the microphone element.
The PS-6 has the Heil HC-6 element which is a wide range dynamic element
which has a relatively low output.
The ProSet-K2/K3 uses an electret element which has a high output level
- it needs to have bias turned on.

The K3/K3S is quite capable of handling either of them.

Re: [Elecraft] Elecraft gear relative IMD

[Jim Brown]

On Thu,12/31/2015 4:34 AM, Kevin Stover wrote:
IMD is not regulated 


It is, as part of the wording of regulation of transmitted bandwidth, 
but the wording doesn't include numbers. The regulation states (I'm 
paraphrasing from memory) that the bandwidth of the transmitted signal 
shall be no greater than required for the means of transmission. I've 
served on the AES Standard Committee, and that's the sort of language 
used to say that the signal should be as narrow as possible, but that it 
is understood that through the years, it will be possible to make 
narrower rigs, so it leaves out the number, which is a moving target.


Elecraft has pretty well set the standard for the bandwidth of a CW 
signal, thanks to the careful control of the keying waveform, pretty low 
IMD, and a design architecture that produces very low phase noise. In my 
tests, I see the K3 as no cleaner than other rigs I've tested on SSB, 
but significantly cleaner on CW, RTTY, and digital modes.


Important note: IMD strongly affects the bandwidth of a CW signal, 
because CW is 100% amplitude modulation of a carrier by a square wave. 
Square waves have an infinite number of harmonics, the strength of which 
are related to the rise time of the CW keying (and NOT to CW SPEED). The 
IMD of a gain stage that amplifies that signal WILL produce sidebands 
(clicks). CW keying bandwidth can easily be measured using a spectrum 
analyzer that has low enough resolution bandwidth. A P3 can do it, and a 
P3 with SVGA has even lower resolution bandwidth. Likewise, an SDR with 
suitable software can do it, and I'm planning to buy an ANAN 10E for 
measurement only.


But the FCC Rules make the operator responsible for occupying the 
minimum spectrum. So that means buying a rig that's clean in the first 
place, giving the rig enough DC voltage, and not overdriving audio 
stages and power amps.

Hi George:

Here, in EPA with a Verizon FiOS account, even the IP address is not working.

Re: [Elecraft] KIO3B Audio Spec

[Don Wilhelm]

Bob and all,

Bonding to a common point may not cure hum and buzz.
Follow the advice of Jim Brown K9YC and bond from equipment to equipment 
- following the path of the shields on unbalanced audio cables and RF coax.
In other words, bond from the computer to the K3 (or from the computer 
to any interface box, and then the interface box to the K3).  The K3 to 
amplifier if present, then to the tuner if present.


The bonding wires will take the majority of the current that *might* 
otherwise flow on the shield of those cables and reduce the possibility 
of noise coupling into the signals.


Whether you also bond to a common point in the station is an entirely 
different matter.  That common point ground may do well for AC safety 
and possible a measure of lightning protection, it will do nothing for 
the coupling of hum and buzz onto the signal paths.


Jim often talks about the "pin 1 problem" which is part of the 
situation, but providing an extra low impedance path direct from 
equipment to equipment will do more to keep all pieces of your equipment 
at the same relative potential than any other means.


73,
Don W3FPR

I have all of my station equipment bonded to the common point on the

Hi Bob,

Yes, the harmonics are visible but down a comfortable more than 70dB below
the fundamental. There is still a little bit of junk around 3900Hz (it was
there on the analog line out, too).

PS. Is a schematic forthcoming any time soon? This is the first radio I have
owned ever, with no schematics.

Re: [Elecraft] Elecraft Website

[Richard S. Leary]

Bob,
Elecraft site comes up fine here, south of Tacoma, WA. Using Comcast cable.
URL I use is http://www.elecraft.com/, then just work through the site. When
I have a connection problem, I usually just unplug the power to both my
router and modem. Let them sit about a minute or so, then power them back
on. I do the router first, let it stabilize, then the modem. Don't ask, it
just works. Good luck, have fun, and HNY to all.

[Elecraft] (K3/K3S). Eliminate the 4 sec diddle with FSK-D and KY commands using n1mm??

[Nr4c]

I'm trying to set up n1mm for the RTTY contest. I'm attempting to use KY 
commands and all is well except I can't get rid of the annoying 4 seconds of 
trailing fiddles at the end. 

Yes, I've tried adding a {RX} at the end, I've tried every iteration of the "|" 
as is used in the K3 memories. I think this has potential but have to solve 
this problem. I won't be too popular this weekend if I'm adding this artifact 
to every transmission. 

Any chance of making this a toggle so we can by-pass it in config?  I assume 
it's there for "paddlers" to have a short pause time or not stopping and 
starting so much for slow code. But even a 1 second hold would make this 
tolerable. 
Help!

Re: [Elecraft] KIO3B Audio Spec

[Bob McGraw - K4TAX]

Yes, this is correct.

I have all of my station equipment bonded to the common point on the 
station power supply.   And I do not use any "ground" to the outside 
world from my 2nd floor station.  Works just great, all bands 160M - 23 
cm, any power level to legal limit, any mode.

Well Jim and I are at 100% opposite positions on this point.

Bonding from equipment to equipment is a series circuit in which the 
voltage divides across each value of R.  Thus none of the equipment will 
be at zero potential.


By using a bond conductor from each piece of equipment to a common 
point, this provides a star system which is endorsed by most audio and

Re: [Elecraft] Elecraft gear relative IMD

[Don Wilhelm]

Being New Years Eve, it is nostalgia time, and I think it appropriate to 
discuss those antique stations.


If you want to hear how bad some of those antique transmitters were, do 
listen tonight for SKN.
Bad chirps, bad keyclicks and lots of phase noise that spread the 
signals out over a large portion of the band.
The bands today are more crowded than they were back then, and while it 
is legal to use those antique transmitters and receivers, I do not think 
it should be an everyday event.


Yes, I know several hams who are into 'boat anchors', particularly those 
old AM transmitters.  Fortunately, that crowd concentrates on 80 meters 
when the band is not full of signals, but listening with today's more 
selective receivers and hearing signals in a 'net' so spread out and off 
frequency, it amazes me that we were able to communicate easily back 
then.  BUT we did, and had fun doing it.


I would not advocate using those transmitters and receivers in a contest 
today, but they did work for us back then.  BTW, I was first licensed in 
1955, so you can perhaps understand the advances in technology that I 
have seen over the years.  There has been a LOT.


I have often considered building again my Novice transmitter which I 
assembled from the article in the 1955 ARRL handbook (a 6CL6 xtal 
oscillator and a 6146 final), but obtaining the parts is almost 
impossible.  Can you find 1 1/4 inch diameter, 4 pin coil forms these 
days?  Maybe, but they are prohibitively expensive, and the power 
transformer is almost impossible to find although back then, they were 
quite common because they were used in TV designs.


I pass by the flea market areas at hamfests and get enough of my 
nostalgia satisfied by looking at those old transmitters and receivers 
that I drooled over 'way back then' knowing that as a teen with limited 
income I could never afford them.  I don't have time nor energy to 
restore any of those 70 pound radios, nor does my hamshack have space 
for them, so I look and marvel, but do not take any of them home with me.


I do have my homebrew receiver, a version of the HBR-16 and an old NC100 
receiver that I may someday bring out of the attic and bring back to 
operational status, but that is pretty far down on the priority list for me.


Enjoy SKN and listen to those old transmitters (and even listen on your 
vintage receiver).  It is a telling story of the history of ham radio 
and the gear available in the years gone by.


Happy New Year.

Don W3FPR

Re: [Elecraft] Elecraft Website

No problems from rural Colorado using satellite.  FYI, there are a lot 
of players involved in transporting web data from a server to your 
browser.  Sometimes a given url will get blacklisted because something 
suspicious was detected.  These false alarms usually clear up in an hour 
or 2.  Be sure to clear your browser cache before retrying.  Rebooting 
won't clear it.  Each browser is a little different.  Do a Google search 
on "clear cache" and your browser name if you can't locate the proper 
option.

The same is true for Ham rigs. It's perfectly okay to run an old Heathkit

rigs.


WRONG!  The rule about bandwidth governs.


The bottom line is to make sure the rig you have is being operated to
produce the cleanest signal its design allows in the mode of operation being
used.


The rule says NOTHING about the design of the rig. It speaks ONLY about 
the means of transmission, which refers to the communications mode (CW, 
SSB, FM, RTTY, PSK, etc.)



That's why double-sideband amplitude modulation is still legal even though
it requires more than twice the spectrum of an SSB signal and CW is still
allowed even though SSB and the various digital modes provide the same
information in yet smaller bandwidths.


WRONG. Double-sideband AM with a carrier is legal because it is a 
DIFFERENT mode permitted by the FCC Rules.  (A3 is the FCC designator). 
SSB is J3 if the carrier is suppressed. CW is A1.

Re: [Elecraft] KIO3B Audio Spec

[Don Wilhelm]

Zero potential is not necessarily the criteria that is to be achieved.

The important point is that adjacent pieces of equipment be at the 
*same* potential, whether that be at zero or 100 volts potential.
OK, that is an extreme example, but the point is that there should be a 
low resistance connection between devices sharing an unbalanced 
connection between the two, and that low resistance connection should be 
something other than the shield of the audio or RF unbalanced cables.
The easiest way to accomplish that condition is to bond the equipment 
from point to point by good heavy wire or braid.


Since we commonly use computers in our ham stations, that is one source 
of hum, buzz and other noise.  Bonding the computer straight to the 
transceiver will cure many ills.


We did not have those problem in older gear where the connectors were 
mounted to the enclosure of the equipment, but modern construction where 
the input and output jacks are mounted to the PC board causes stray hum, 
buzz and noise and RF currents to be coupled to the PC board rather than 
being routed to the outside of the equipment enclosure is one of the 
primary causes of the problem - that is the "pin 1 problem" that Jim 
Brown K9YC refers to.

H! The ancient and accepted way to bring all of the chassis at the 
same potential is to BOND THEM TOGETHER!  This is EE101, simple Ohm's 
Law. You do NOT need transformer isolation if the equipment is properly 
bonded! http://k9yc.com/GroundingAndAudio.pdf  Nothing but plain, 
ordinary copper wire.

Re: [Elecraft] Elecraft Website

[Lynn W. Taylor, WB6UUT]

Patience.  Seriously.

We need to think about two questions:

Who owns the internet?

How is it managed?

The answers: nobody owns the internet.  It's a network of networks 
("Internet" is a contraction of inter-network, the protocol to tie 
multiple networks together).


The various network owners manage their own networks.  The really large 
networks can be called "backbones" but even that term is somewhat 
meaningless.


The "management" is essentially chaotic.  Nobody is driving the bus, but 
people make sure that all of the bus parts end up at the next stop.


From here (on Verizon's dismal rural DSL) there are five networks on 
the way to Elecraft.  Any one of them can have a bad day and I'd have 
trouble reaching www.Elecraft.com.


The one thing I'm certain of is that all of us follow different paths 
through different networks, and any of those intermediate sites can have 
trouble.


The odds are that it's not your provider, and it's not their provider, 
it's someone in-between, and generally speaking, they won't take 
complaints from you because you don't pay them. They'll fix it sooner or 
later, because someone who does pay them will be having issues.


The amazing thing is that most of the time the internet is incredibly 
reliable.  It's mostly self-healing.  Mostly.  Kinda.


It's fun to talk about.

Re: [Elecraft] Elecraft gear relative IMD

[Ron D'Eau Claire]

The FCC here in the USA does not require having a rig that meets state of
the art specs, either for Amateur or many commercial applications. 

When checking shipboard radio installations in preparation for their annual
FCC inspections, I used a variety of different specs the gear had to meet
based on its year of manufacture. Older gear had a lot looser specs than the
newer stuff. 

The same is true for Ham rigs. It's perfectly okay to run an old Heathkit
AT-1 or a 1930's homebrew rig with cathode keying today as it was back then,
even though the keying bandwidth will be substantially greater than modern
rigs. 

The bottom line is to make sure the rig you have is being operated to
produce the cleanest signal its design allows in the mode of operation being
used.

That's why double-sideband amplitude modulation is still legal even though
it requires more than twice the spectrum of an SSB signal and CW is still
allowed even though SSB and the various digital modes provide the same
information in yet smaller bandwidths.

Re: [Elecraft] Elecraft gear relative IMD

[Ron D'Eau Claire]

Sure the rules apply, and rules for spectrum bandwidth provide no numbers,
saying only "... in accordance with good amateur practice."

Right now, New Year's eve, there is an on air event taking place, Straight
Key Night, that encourages the use of antique rigs on the air and is
sponsored by the largest association of Radio Amateurs in the USA, the ARRL.


Amateur radio is still a homebrewer's hobby, encouraging Hams to design,
build and maintain their own rigs frequently without access to modern
equipment to evaluate their performance. I believe it is for that reason the
rules are very loose about things like spectrum bandwidth.

WRONG!  The rule about bandwidth governs.

The rule says NOTHING about the design of the rig. It speaks ONLY about the
means of transmission, which refers to the communications mode (CW, SSB, FM,
RTTY, PSK, etc.)

WRONG. Double-sideband AM with a carrier is legal because it is a DIFFERENT
mode permitted by the FCC Rules.  (A3 is the FCC designator). 
SSB is J3 if the carrier is suppressed. CW is A1.

Well Jim and I are at 100% opposite positions on this point.

Bonding from equipment to equipment is a series circuit in which the 
voltage divides across each value of R.  Thus none of the equipment 
will be at zero potential.


By using a bond conductor from each piece of equipment to a common 
point, this provides a star system which is endorsed by most audio and 
system design specialists.   It provides the lowest resistance as all 
conductive paths are parallel.

Re: [Elecraft] Elecraft gear relative IMD

[Grant Youngman]

I honestly don't understand why this keeps coming up, or what it has to do with 
Elecraft. 

I'll operate my DX-40, or Viking II, or 100V or other vintage rig anytime and 
anywhere I please, thank you. These radios don't generally chirp wildly or have 
substantial phase noise. If phase noise is a concern, be concerned about some 
of the infamous 80's import all mode solid state, with a hundred tiny knobs, 
impressive looking expensive radios that could well clear out a band. 
Fortunately that junk doesn't show up very often. 

A well built tube transmitter, vintage or not, is a good thing. A modern 
receiver is a great tool and we wail when it's S-meter reading is off by .01dB 
or it drifts 2 HZ or there's something wrong with a Windows driver or whatever. 
  A vintage one with a pair of 6V6s driving a large loudspeaker and an 
operating manual that doesn't require a search engine has character, soul, and 
audio that has to be heard to be believed, even if it can't read freq out to a 
few milli-hertz :)

And other than contest weekends, I keep searching and searching for crowded 
bands ...
