That's true of ANY counterpoise, whether on the ground or not. In 
general, higher is better. The closer any part of an antenna is to the 
ground the more power the ground sucks up that won't be radiated.


There is both capacitive and inductive coupling to the earth. Both cause 
loss. That's why higher is better, and why an earth connection is NOT 
usually a good thing for signal strength. It IS a good thing at the base 
of an antenna for lightning safety.

Re: [Elecraft] mic - David Clark

Hmmm ... I've had it for several years and it saw some use before I got 
it but I doubt it's old enough to be a carbon mic like the WW2 T-17.


I just assumed the "noise cancelling" part applied to the headphones.  I 
didn't know it might apply to the mic.  There's no external noise in my 
shack to cancel anyway.


The connector is round and the contacts stick out of the face.  I think 
there are 6, maybe Headphones, Mic, and PTT?  There's a push-switch in 
the cable.  It looks like the connector fits over the panel connector 
and you twist is to lock it ... like a BNC.  I don't think the 
headphones are stereo which is a big negative with my K3.


I was just curious.  This sounds like a project for some time when I 
have exactly nothing else to do. [:-)  Thanks for the info

Re: [Elecraft] 6m off-frequency

2017-06-11 Thread Erik Basilier

Ian,

I don't have any suggestions for a solution beyond what others have already
mentioned, but as a side note I would like to discuss the concept of "off
frequency". 

It seems to me that these days, on the HF bands that I frequent, more and
more people tune SSB to where the displayed frequency is on an 500 Hz
boundary, and their rigs have sufficient frequency accuracy that excellent
copyability results without any further adjustment. This approach is much
faster than tuning by listening for most natural voice, which for me takes a
few moments. When I look over the shoulder of operators at Field Day, a
surprising percentage of people take a long time trying to tune for natural
voice, and still don't end up even close to correct tuning, so they should
be helped even more by just "going for the zeroes". While I haven't used 6m
recently, I would guess that the "zeroes" approach has become common there,
although the average rig may not be as frequency-accurate there as it would
be on the lower bands. Further to how to tune in other stations quickly, I
just found another way to minimize SSB tuning time when scanning the bands.
I configured the K3 to use the RIT knob to act as a coarse tuning knob
(CONFIG: VFO OFS), with 500 Hz steps (CONFIG: VFO CRS). I also set the main
tuning knob to a 500 Hz boundary. After setting things up this way, I use
the P3 with a span of +- 25 kHz to identify the next SSB station up or down
the band, then turn the RIT knob to put the passband over it. That puts me
close enough that only one more 500 Hz step will tune to perfect voice
clarity, and many times I will be tuned perfectly with no adjustment at all.
Much, much faster than cranking the VFO knob, first to approximate frequency
and then fine adjustment by listening. Occasionally it happens that the
station is not on a 500 Hz boundary, and I have to turn on RIT and fine
adjust by the RIT knob. Then I will usually soon hear that the station
saying that he is using an older rig. That is becoming rather rare, though.
After I am finished listening to the "off frequency" station, I just turn
off the RIT, and the RIT knob lets me tune in the next station quickly using
500 Hz steps, while leaving the main tuning knob alone. Now tuning SSB
stations is a bit like tuning FM "channels". I am not advocating
"channelizing" the HF bands, as we should have the freedom to select our
frequenciy according to the situation, but a lot of times, using a frequency
ending in zeroes saves time and effort.

Erik K7TV

Subject: [Elecraft] 6m off-frequency

All,

I've been operating a little in the ARRL VHF contest this weekend, on 6m,
and I'm having an interesting, and not good, experience. Everyone I try to
work is reporting that I'm off frequency by about 500 Hz. I don't have
RIT/XIT enabled. My K3, s/n 281, went to Elecraft earlier this year for some
upgrades and a tune-up, and came back with a clean bill of health and
meets/exceeds specs.

I admit, I am new to 6m operation, but this constant report of being
off-frequency concerns me. Is there some calibration step, specific to 6m,
that I missed? I don't get this report on any other band, and have never
gotten it in over 6 years of operating this rig. My assumption is that if it
came back from the Mother Ship clean, and I've never used 6m before, that it
should be properly calibrated.

Any guidance/advice is greatly appreciated.

Thanks and 73,

Re: [Elecraft] Field use of Counerpiose

A counterpoise on the ground or buried a short distance [~5-10 cm] is a 
low resistance path in parallel with the much higher ground resistance 
for the return current for unbalanced antennas [verticals, end-fed 
wires, etc.]  They're often called radials or ground-screens, and in 
general, more is better, but one is a whole lot better than none.  The 
return current decreases rapidly away from the antenna so more shorter 
radials is usually better than a few longer ones.  Such a counterpoise 
wire is effectively grounded regardless of what you do at the end.  If 
it feels better to tie it to a stake in the ground, by all means do so.


An elevated counterpoise is just another element in your antenna. Length 
matters.  For a single wire fed at the end, if the counterpoise is the 
same length as the wire and elevated, it's a center-fed dipole again 
[whether or not it is resonant].  In the field, mine lays on the ground 
and is about 1.5 ft longer than the wire [~25 ft].


If you're next to salt water, toss it in.  MF survival radios [500 Kcs] 
from WW2 had a balloon or kite to raise the wire, and a weighted braid 
to toss over the side of your raft.

True "noise cancelling" mics sound awful. They work on the principle of
cancelling noise more than an inch or two from the mouth. SUPER noisy
places like aircraft are the ONLY place to use them.

Most hams who have too much background noise either don't work the mic
close enough (it should be an inch or two above and alongside the
mouth), or have processing and/or mic gain turned up way too high.

That's very different from a DIRECTIONAL mic, which has the approximate 
pattern of a 2-el Yagi. So it receives 3-6 dB less noise, but it also 
boosts the bass, which is a bad thing for audio "punch."


The boom headset mics we've been discussing are omni-directional mics

My guess is that the connector was a proprietary one matching the

It might work, Fred.  Check this page: 
http://www.acousticom.com/2015/aviation-headset-information-specs/


I always thought that aviation headsets met some earlier mic standard 
(carbon?), but this page says that's not right.  Note that the actual 
headset speakers/transducrers have a rather high impedance, though I 
suspect they may work with a K3S anyway.


Someone else can chime on a load of 300 ohms using the K3S's headphone 
driver circuit. My DCs are way too buried to find and check this right now.

Just curious ... I inherited a David Clark noise cancelling aviation 
headset/mic from a neighbor who was a US Forest Service pilot.  I've 
never tried it, the connector is strange.  I'm not even sure I know 
where it is right now.  Will it work with my K3 if I can find it and get 
the connector compatible?  I know they're expensive.


Maybe it will cancel the powerline noise on 80? [:-))

Yes, at about $250 retail (plus adapter cable), the Pro 7 is more than
five times as expensive as the Yamaha CM-500 (electret mic), Koss SB40
(dynamic mic) or SB45 (electret mic) headsets.   Both the Yamaha and
Koss headsets have outstanding 120 Ohm headset drivers with sensitivity
rated at 96dB/mW and microphones well tailored for voice work. Heil
does not even publish the impedance or sensitivity for their headset
drivers!

For the price of a Heil Pro 7 one could get a Broadcast headset like
the Audio Technica BPHS1 ($199), Sennheiser HMD280 ($249) or Shure
BRH440M ($249) - all of which are significantly higher quality than
the Pro7 (and field proven).

Re: [Elecraft] 6m off-frequency

Indeed!  The huge gulf between "precision" and "accuracy."   A display 
with gobs of decimal places can be colossally but precisely wrong.  It 
is also true that frequencies that end in .000 are "better" for many 
people so I avoid them when looking for a run frequency. [:-)


This problem on 6 meters sure sounds like XIT or maybe SPLIT is engaged 
for that band and has been remembered.  Years ago, 30 meters went dead 
with infinite SWR on my K3 -- all the rest were fine.  Wayne finally 
telephoned me and his first question was, "Which antenna is selected?"  
Antenna selection is remembered by band.

Re: [Elecraft] mic

2017-06-11 Thread Bill

After having tinkered with many different kinds of mics on the K3 - I 
feel very confident in saying that a K3 can make ANY mic sound great. It 
is all about learning to use the menu settings and not about how much 
you spend for the microphone.


This is not to say that some microphones are not physically better 
built, or may look better to the beholder. It is only about how they can 
be made to sound.

Mics of any kind - dynamic or condenser/electret - with wide frequency

[Elecraft] NorCal 40a

2017-06-11 Thread Mark Glenn

Wayne & Eric,

 

I listened to Eric Guth's interview of Wayne on the QSO Today podcast where the
NorCal 40a was discussed, along with   David B.
Rutledge's book.  It looks like the NorCal 40a is no longer available in kit
form.  I was wondering if Elecraft would consider bringing that kit back to
general availability.  It seems that there could be a market for it in the
education space, particularly if sold along with Prof. Rutledge's book.

Re: [Elecraft] 6m off-frequency

2017-06-11 Thread Bob McGraw K4TAX

You say RIT is not engaged, but what about XIT?   Either of these being 
ON can cause an issue in this regard.Additionally, the way one 
person tunes to a SSB station may cause some frequency disparity between 
two stations.   Excercise: with eyes closed, tune to a station and then 
look at the display.


Also, the advent of digital readouts can cause this type of discussion 
to arise.  Seems that everyone thinks the digital display is absolutely 
accurate.  In most cases it is not a frequency measuring system but 
rather a frequency display based on certain accepted oscillator 
frequencies {which may or may not be absolute}  and math calculations if

Yes, that's a known issue. MANY years ago I worked out a simple mod for 
the K2 to add 6-8 dB of gain for a dynamic mic and add some LF rolloff. 
I think W3FPR has notes on it. There are other mods further along the 
signal chain, but they are not as simple.

Ian,

Can you receive any station at a known frequency.  Here in the US it is easy to 
use WWV, but other standard frequency stations exist around the world.

Tune to the standard frequency station and do the Reference Oscillator 
Calibration.  K3 manual page 50.  Use Method 2.

I cannot guarantee it will fix the problem, but it is the first thing to try.

Have you experienced this on other bands, during casual operating since the

I find that when I am on SSB, I tune until my ear may likes what I am

Pelican 1200 and it hold everything I need without being too big.

For $40, it is a great deal

It depends on your needs. This $6 watertight case seems to fit for me. I will 
put this into my small Kelty sling bag (now they call it a tactical sling) and 
have plenty more space for extras, and carry hands free on my back. The big 
Pelican case is way too big and overkill in this scenario.

Re: [Elecraft] Counterpoises and Grounding

2017-06-11 Thread David Cutter


Hello Stan

My note is a little off topic because I like to remove the counterpoise all 
together by addressing the issue of common mode current.


I thought that, rather than getting embroiled with definitions, I would 
offer something different. You don't say what bands you operate but your 
crucial point is you are up in the sky so to speak and I've been there and 
suffered accordingly.


*Until recently* no commercial antenna manufacturer had conquered the mighty 
common mode current problem of the off-centre-fed dipole.  Since you run QRP 
you don't need anything big or heavy duty, you might consider the offerings 
from Spiderbeam. They currently do a 40m version which covers all bands to 
6m and your KX3 will handle any slight mis-match with ease.  A friend of 
mine ran one of these as a sloper out of his window using a KX3 and got 
excellent results.  No external tuning box or counterpoise is necessary, 
it's all handled in the special dual choke balun.  I understand they are 
working on an 80m version. I have no commercial connection with the company.


If you prefer to build your own aerials, then you can see the website for 
DJ0IP who in my opinion is now the world authority on these aerials having 
done more research and *practical testing* than anyone.  I doubt if that's 
an exaggeration.  On his website you will see how to make your own quite 
inexpensively.  There is also a lively and progressive forum dedicated to 
the ocfd.


If you would like to know more, do get in touch.

David
G3UNA

ps I use a special version of the ocfd called the end-connected off centre 
fed dipole.

Subject: [Elecraft] Counterpoises and Grounding


I note that the subject of counterpoises has been debated many times in 
this

forum but I have not seen the subject of tuneable artificial grounds
discussed. As no doubt many are aware, operating from a location remote 
from
the ground has its problems in ensuring effective grounding, especially 
with

end fed wire antennas. I have this problem as I operate from an upstairs
shack. I have overcome the difficulty by using a tuneable counterpoise
arrangement in conjunction with my end fed wire antenna. The EFW antenna 
is

approximately 66ft (20m) long and the counterpoise wire 16ft (5m).

Using my homebrew AGT and my KX3 is a simple process to tune for 
resonance.
a) Tune to the desired frequency using the internal KX3 auto tuner. b) 
Tune
for maximum current using the AGT meter (low power recommended for 
tuning).

Repeat the process as necessary to obtain best match. Usually 1:0 or 1:1
(KX3 reading). I only operate with 5 or 10 Watts. Apart from overcoming
grounding problems you get a resonate grounding system not an 
approximately

resonate one as used in most circumstances. This in my view, is a suitable
compromise in overcoming difficult grounding conditions, although I do not
advocate it in preference to an extensive grounding system where 
conditions

permit. One point to note is that if an external power supply is used the
output must be isolated from ground and suitable precautions taken against
lighting strikes. Many designs for simple homebrew AFT projects are
available on the web and MFJ also do one commercially. Obviously different
or different multiple lengths of counterpoise wires can be used to get the
best setup with your antenna.

Have you experienced this on other bands, during casual operating since

I find that when I am on SSB, I tune until my ear may likes what I am 
hearing , and as such,  I may not be exactly on their frequency.   (that 
is one reason for RIT!)  Also, I have found that some ops feel that they

[Elecraft] KPA500 in host/server mode - intermittent failures

2017-06-11 Thread Michael Walker

I am having an issue with the KPA500 software.

It works fine on one PC, but when you use it in client/server mode, which I
do a lot, It randomly fails on the the client PC.  I can see what it is
doing, but no joy for any commands.  It has worked at times.  it is also
not a timeout issue.

The network is both devices on the same subnet plugged into the same switch
with 3ft cables.  Other applications like PSTRotatorAZ work fine when doing
something similar.

The ports and ip addresses are correct.  One other ham friend of mine
reports the same intermittent failure.

Is anyone else using this mode and having similar issues?

Mike va3mw

ps.  I would include screen shots, but the small image size restriction
makes is hard to do.

Re: [Elecraft] mic

See my earlier responses to both gentlemen.  

1) Frequency response  yep, understand and agree.  One of the things
I learned from one of Jim's papers as a matter of fact.  Which is why I
modified the mic design slightly to produce a frequency response curve
more suited to amateur radio and as clean as I could possibly make it
within my resources.  Thanks, Jim.
2) Also why I use Jim's recommendations for TX EQ on the K3s as a
starting place to NOT waste power.  Thanks again, Jim!

I don't consider it EVER a "waste" when I 1) learn new stuff, and 2)
have fun... which of of course my primary motivation for doing ANY of
this in the first place.
And the "brand name" on my microphone is "Autery" or "KY5G".

Hi Gang:

I'll add my agreement with what other professionals have said.  And, I'm a 
retired Technical Supervisor for Audio and Post Production at CBS-TV.  We had a 
ton of really good microphones at our disposal.  But I use the MH3 with my KX3

Subject: Re: [Elecraft] mic

Bob and Jim have excellent points.

There is one advantage for the electret mic compared to a dynamic
mic.  Electrets are generally 26 dB "hotter" than a dynamic mic
and thus are much more resistant to common mode RF feedback and
magnetic coupling.  However, that assumes the transceiver is
designed for the higher input level and properly reduces gain
before the mic gain control.

Mics of any kind - dynamic or condenser/electret - with wide frequency
response are completely wasted for amateur radio (or any communications
application).  You really want a clean 200 Hz - 4 Hz response.  Lower
frequencies cause distortion and waste power, higher frequencies are
simply lost in the "channel noise".

Like Bob and Jim, I spent my professional life in the recording and
broadcast industries.  Amateurs waste far too much on over spec'd
microphones and fancy "brand name" advertising campaigns.

Re: [Elecraft] mic

Well, in my admittedly inferior level of "studio engineering" skills and
experience, I must be the proverbial "blind hog", because I seemed to
have "accidentally" "tripped across" a combination and setup that does
the job well.  

As I told Jim, today and the last time we had this discussion.  Man
asked me what I run, and I told him.
For some folks, it's not just about doing it cheaply, not about doing it
efficiently, etc, etc...
Everyone has their own reasons why they do what they do.
I "built" and customized this mic because I wanted to do it.  It was
FUN, and that's why I use my increasingly limited time on this earth in
amateur radio.  To have fun.  

It was an excellent academic and skills exercise, too.  And one simply
cannot argue with the results.  No less than 15 people have offered to
buy the setup sight unseen.

But, don't despair...  I still read everything you smart guys write, and
I use every little tidbit I can.  I've done my best to surround myself
with smart folks all my life.

e.g. in this instance, I used Jim's recommendations as a starting point
to set up the TX EQ on the K3s...  THANK YOU, Jim!  

73 and have a wonderful Sunday!

PS - When the mic project started, I was ALSO building a small studio
setup to do voice-over work.

Re: [Elecraft] mic

2017-06-11 Thread Joe Subich, W4TV



Bob and Jim have excellent points.

There is one advantage for the electret mic compared to a dynamic
mic.  Electrets are generally 26 dB "hotter" than a dynamic mic
and thus are much more resistant to common mode RF feedback and
magnetic coupling.  However, that assumes the transceiver is
designed for the higher input level and properly reduces gain
before the mic gain control.

Mics of any kind - dynamic or condenser/electret - with wide frequency
response are completely wasted for amateur radio (or any communications
application).  You really want a clean 200 Hz - 4 Hz response.  Lower
frequencies cause distortion and waste power, higher frequencies are
simply lost in the "channel noise".

Like Bob and Jim, I spent my professional life in the recording and
broadcast industries.  Amateurs waste far too much on over spec'd
microphones and fancy "brand name" advertising campaigns.

Sorry, but you guys are WAY over the edge on this. As a retired

I wouldn't waste any of them in a ham station. I'm VERY happy with a 
Yamaha CM500 since W6XU turned me on to it around 2009, at a fraction

K3s (plural, not the new K3S). Any decent electret will work as well, 
especially with the EQ built into a K3, K3S, KX3, KX2. Those large

or a great jazz big band, but they are a waste in the ham shack.

Re: [Elecraft] mic

2017-06-11 Thread Brian Denley

Agreed Jim but I haven't spent much money on any of the mic stuff and I also 
used a cheap ($40) headset rather frequently.  I do, however, prefer the 
dynamic mics.  The condensers that I have tried seem to pick up way too much 
background noise.

Re: [Elecraft] [KX3] HI CUR error with 2m module

2017-06-11 Thread Don Wilhelm


Steve,

Do you have a dummy load that is good up through 148MHz?
If so, Connect it and see if you get the same error.
If not, investigate your antenna and feedline.
If it is still present, contact K3support.

The only thing I saw in the archive was a mention about a loose SMA

Re: [Elecraft] Counterpoises and Grounding

2017-06-11 Thread Stan GW3SRM

I note the comments generated by this topic. I must admit the use of the
term 'tuneable artificial ground' generated some controversy but it is
widely used in both amateur and commercial literature. Perhaps 'tuneable
counterpoise' would have been better and the term 'artificial' is
superfluous. Safety earthing (grounding) is of course used for protection in
our 50Hz mains power distribution system, lightning protection etc. The
counterpoise is of course part of the antenna system described and I thought
antenna radiation and earth conductivity were well understood.

I regret that my submission should have created such heated comments.

 

Nuf said.

[Elecraft] MH3 rattle?

2017-06-11 Thread Brad J. Butler via Elecraft

Good morning everyone,

 

I've got a new MH3 that hasn't ever been dropped.  When I *gently* shake it,
I hear something rattling around in it.like a spring of some sort.  Is that
normal?  If I "roll" it in all different directions, I don't hear anything
rolling around on the inside, so there's nothing that has come loose, just a
little something that's shaking around if I gently shake it side to side.

 

Thanks!
