And things seem to be getting worse with every contest. At least 10% of the 
SSB signals I hear are so badly processed that the audio is so badly 
distorted that I can't copy the call sign, even if I listen to it a dozen 
times. And yes, some of these lids consider themselves big guns. 

Several times in the last month or so, R1FJM has been spotted on 20M SSB. I'd 
like to work him, and I can hear him, but his audio is so awful I can't 
understand a word. If someone knows him, please tell him.

[Elecraft] OT: Sunspots

[Don Rasmussen]

I can hear the half empty types now - what a mole hill, who needs a K3, why 
even bother to show up for such a small solar maximum. 

The way I remember it, the last cycle was PLAGUED by geomagnetic storms that 
always came at the worst possible time (FALL). But the numbers looked great. !!!

http://www.zerobeat.net/wb8yqj/ssn_predict.jpg

Looking at the graphic, two things:

- We are well into the upswing - further than I would have guessed - happy days 
they are here again. ;-)

- Look at the aweful, slow, agonizing decline from the last cycle - ack!

[Elecraft] K3 Notch

[Don Rasmussen]

Engineering trade offs are so interesting.

Unfortunately the K3 notch works outside of the AGC loop. However everything 
else about the K3 sounds brilliant and natural using Lyle's IF DSP in all modes.

The FT2000 has it's manual NOTCH inside the AGC loop, kudos on that, but the IF 
DSP receiver does not sound quiet and natural on CW, like K3 does, if there is 
any noise on the band at all. 

What was Yaesu's solution? They assigned the sub receiver to be analog, so you 
have a hybrid, which "solves" the problem.

However - switching from the digital side to the analog side really contrasts 
just what a noisy receiver you have on the IF DSP side when there is any band 
noise. Why doesn't K3 have this problem? I don't know. 

It seems silly that K3 can get the DSP proper for all modes, and Yaesu has you 
flipping from one side to the other - but the FT2000 has an ergonomics package 
that really rocks. It adds to operating fun if you have nothing on the line 
(like contest operation).

Perhaps they're using a fixed level of hardware AGC ahead of the
ADC or intentionally holding the level to the ADC well below
saturation (forfeiting dynamic range) to prevent a strong
interfering signal from clipping.

[Elecraft] K3 Notch

[Merle Bone]

The problem with having the manual notch filter outside the AGC 
loop is that if you are trying to notch out a CW signal, although the tone is 
eliminated, the notched signal causes the AGC to pump - thus hurting weak 
signal 
copy. I think whenever you start using the"big tools" you have an idea that you 
are not in the  "optimum receive situation." For me, the ideal would be "auto 
notch" outside the  loop and "manual notch" inside the loop.

Part of the problem is that a DSP radio needs to have the notch after
the AGC since part of the function of AGC is preventing the ADC from
being over driven.  If the notch is placed BEFORE the AGC detector
the notch will cause the interfering signal to INCREASE at the input
of the ADC.

Yes, it would be nice for the notch to allow the receiver to return
to normal gain when the interfering signal is removed but that would
merely cause the HAGC to come into play.

[Elecraft] ERR 12V on K3

[Derek Cohn/WB0TUA]

Hi Everyone,

I'm still learning how to use my K3 and thanks to the help of everyone on this 
list, I've been able to sprinkle in a few RTTY contacts with my CW.

A couple of days ago, I was on RTTY and ran into a problem.  I'm pretty sure 
(but not 100% certain) I had cranked the power down so it showed about 50W out 
on the K3 meter and was yapping away.  I had essentially finished the QSO and 
tried to send a couple of farewell characters and the transmitter didn't turn 
on.  I looked at the display and saw ERR 12V displayed.  I got out the manual 
and read the error could be do to the PA module dropping into bypass mode.  I 
power cycled the radio, and tried it in CW...I had about 5 watts out.  I think 
adjusted the power control until I had full power again.  So, I have two 
questions:

1) Did I overheat the K3 running it in RTTY to cause the ERR 12V to be 
displayed?

2) If I overheated the radio, should that have happened with the output at 50w 
on the K3 internal meter?

Thanks for any help you guys can give me!

Bob's comment above is right on the money and is well worth re-reading.

Professional announcers use proper mic technique *and* they work in 
sound booths or acoustically inert studios. Sports announcers who must
work in noisy environments use headsets with high quality noise-canceling 
mics inches from their lips, followed by processors far more sophisticated
than any used by hams.

A tip to the phone contest fellows: prepare your CQ loops in a quiet
room well in advance of the event. I am always astounded at the poor
quality of the CQ loops in contests - many from the well known big
gun stations who should know better. I wonder about the impact on the
Q-rate when the listeners (especially those whose native language is 
other than English) have difficulty understanding the CQ loop.

Maybe because nobody notices something else that goes bad.

Life is often full of compromises. If we give up something 
like close-spaced dynamic range or better AGC performance, 
it can sometimes allow us to do the more obscure things we 
would use 1% of the time. :-)

Sometimes engineers overlook something they could have done, 
and sometimes they don't want to compromise something most 
people would find more important.

And do remember, more compression brings up background noise between

compression, a background noise level that would normally produce and

Re: [Elecraft] W2IHY 8 band equalizer and EQ Plus

[Robert Mcgraw]

I said it before and written it before, good audio has to do with a good
mike and GOOD MIKE TECHNIQUE.  The best mike money will buy and poor mike
technique will result in poor audio.

We use noise gates in the professional audio studio to create special
effects.

The noise gate used on ham radio to eliminate blower noise is a false
since of secuirty for when the gate opens, along comes the noise with the
voice.  It only chops the noise in between words.  It is still there with
the voice.

[Elecraft] K3 Programmer's Reference iPhone App Available

[Michael Downs]

For those of you who have an iPhone and would like to have the K3 Programmer's 
Reference as a handy reference on your iPhone, read on. 

I have developed an iPhone app that puts the entire K3 Programmer's Reference 
document in iPhone format for your use. It also includes appropriate 
supplemental information from the K3 Owner's Manual incorporated into the 
reference to make less cross checking necessary as you program your PC to 
control the K3 or write macros.

It is a free application available in Apple's App Store. You can find it by 
using the search terms K3 Programmer's Guide, or just K3 or ks7d. It is 
categorized by Apple as Reference. 

It currently is the only iPhone app available that supports the K3. Hopefully 
some of the other K3 users will develop other iPhone apps for the K3. Enjoy.

Part of the problem is that a DSP radio needs to have the notch after
the AGC since part of the function of AGC is preventing the ADC from
being over driven.  If the notch is placed BEFORE the AGC detector
the notch will cause the interfering signal to INCREASE at the input
of the ADC.

Yes, it would be nice for the notch to allow the receiver to return
to normal gain when the interfering signal is removed but that would
merely cause the HAGC to come into play.

[Elecraft] Re： International Shipping Charges !!??!!

[Johnny Siu]

Hello Nigel,

Just email to Lisa at sa...@elecraft.com and explain to her your situation.  
The shipping of minor items is excessive and I spot the mistakes in shipping 
weight a couple of times.

However, the sales team is helpful and will correct the mistakes right the 
way.  Just send them your email.

主題： [Elecraft] International Shipping Charges !!??!!

I'm wanting to order two items from the Elecraft page, namely a replacement 
MCU
and a packet of 20 panel screws, not really very large items.  However when 
I went to the
checkout to select delivery method the charges struck me as rather 
exploitative. They
ranged from $35 for the screws and nearly $100 for the MCU.  Am I doing 
something
wrong or is this the norm ??

Regards

Nidge (G0NIG)

Re: [Elecraft] W2IHY 8 band equalizer and EQ Plus

[Mel Farrer]

Yes, and watch the ALC level while you are doing it.  I found that you can 
increase the compression and not trip the 5-7 bars of ALC, but it will sound 
terrible.  Stay below 10 dB of compression and under 5 bars of ALC for the 
smoothest sound and lack of splatter.  FWIW.

Follow instructions in the K3 manual to set the meter to read 
compression. Then follow the instructions in the manual for first 
setting the mic gain without any compression, and then set the 
compression with the compression control.  When you talk, you'll see the

Re: [Elecraft] Elecraft International Shipping Charges

[David Lankshear]

I went through the shock of displayed shipping charges some time ago.

 

The solution is to add a short message at the payment stage of the order,
asking the shipping staff

to send items by lowest cost.   

 

For the UK, this is usually an airmail service and it takes 5 to 8 working
days in my experience.

 

I have purchased odds and sods on a number of occasions and have always
found that the Elecraft

staff display common sense with shipping.  Stuff is always extremely well
packaged and for small

bits and pieces, ten bucks is pretty much the norm.

 

If in doubt, drop an email to li...@elecraft.com and she will tell you the
same.

if you want a handheld for a K3,,,or K2  or icom...
check out 
:http://www.shure.com/ProAudio/Products/WiredMicrophones/us_pro_527C_content

you will notice that this mic has a rising hi end response,,, 
popularized by Shure Bros...(not Heil)
for articulationand works great with ssb  not flat ,,,

You could drive a car over the case and not hurt it ,,,
the PTT switch will last longer that all of usnot a mini microswich
The cord, more rubber than plastic,  isn't so stiff or thick it will 
pull that radio off the shelf but close. The 527 requires some 
dc,  the 526 is straight dynamic

while it was made in US now it's made in america,  mexico I think..

anyway , i've got three   one wired for k3 ,  two for K2/ICOM..

sold at all the usual suspect places  and cheaper than the piece 
of junk from  ...

As far as a great base mic.,,, just about anything will do, 
especially if it's an electret ,  as you can eq it to sound like a 
telefunken U-47 ribbon, if you wish...

I also have a sennheiser headset...HMD..280, with the d meaning the 
boom mic is dynamic... a sennheiser HME  would be an electret.
Found mine at dayton, as an AV lab castaway...  ebay is another 
source as new is too much$.
No longer have external eqs here.

I thought any noise gate issues were worked out by lyle.

Re: [Elecraft] W2IHY 8 band equalizer and EQ Plus

[Andy Wood]

I have to agree strongly with Jim - for me, the K3 does not need any form of
external processing or "extras". I receive an unusually high number of
unsolicited comments about the quality of my audio. In fact, here is the
latest email I have received about it after working a few NA contacts on the
75/80m DX window:


Hi Andy,

I was talking to David, W6ANR today he informed me you are running K3
transceiver and you had the best audio he has ever heard from any K3. So I
am asking if you could give a run down on all your setting as you have them
on your radio that pertains to Audio so I can help my neighbor Bob, W9KNI
get his dialed in. His sounds lousy and he has always been a CW man but has
now been enjoying using the mic instead of the paddle.  He has had comments
that he need to dial in his audio so I told him I would help. SO maybe with
all your setting etc I can have a good place to start as I am not to
familiar with that radio. 

I hope your summer was a good for you? Here we are anxious for spring to
arrive so I can get out and do some real work out in the yard and get the
veggie garden started.
 

Best 73,


Rich K7ZV


Here is my reply to Rich:

Hi Rich,

Great to hear from you - it has been a long time since we have worked on
80/75m. I haven't been very active lately, due to work and family
commitments.

I hope I am not going to disappoint anyone when I reveal my audio setup on
the K3 as it is far from spectacular..hi hi. The fist mic I was using is a
five dollar CB type that you could find at any hamfest (no kidding!). I have
not adjusted the TX equalizer so it is still at the factory default (all
"flat"). I do use the compressor, but only allow it to indicate between
about 5-10dB on the meter. I also always make sure the ALC bargraph
indication is well below the upper limit.  For what it's worth, my mic gain
is set to 23 and the compression setting is at 19.

Not very fancy is it? I found the K3 to work well "out of the box". As the
old saying goes "if it ain't broke, don't fix it".


I think this speaks for itself - nothing else required!

Andy  VK4KY

[Elecraft] K2 capacitor specifications

[Dave Clausen]

Hi all-

I'm wondering if anyone knows the part numbers or specifications (e.g.
max voltage, ESR, tolerance, dielectric) for the dark red monolithic
capacitors used in the K2 and associated modules. I'm guessing they
are 50V Panasonic ECQVL-series, e.g.
http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=P4525-ND
, but that's just a guess.

I'm placing an order with DigiKey for some other things, and I figured
I would order a few spares of these while I'm at it.

Thanks,
Dave, W2VV

Re: [Elecraft] K3 Notch

[gary bartlett]

...and while they are at it (Wayne told me it was on the list), do something
to make it easier for us CW contester ops to use Notch.  I wish, when one
first turned on Notch, that the default frequency turned up anywhere except
at the very extreme upper end of its range where, unfortunately, it is of no
value to me.  By the time I dial the notch from 2000HZ to down to where I
need it, it's too late when things are moving quickly.  I have found that
there are contesting occasions in which use of the Notch into a wide filter
is a better solution than very narrowed filters.

When in CW Mode it should default to somewhere closer to where a person
needs it -- i.e., inside the limits of whatever filter is in play.  Or why
not default to the rig's selected side-tone pitch?  That way an op would
know exactly where to go with the Notch control when first turned on.  Even
if the *Notch Go-to-2000HZ* command were turned OFF inside the radio and the
Notch left where last used would be better.  Anything.

I believe that I can show that the K3 Notch was better when the rig was
first new, before an early firmware update came along and broke it by moving
the CW Notch default up to 2Khz.  This is the first radio that I've owned in
which I have used the Notch and found Lyle's work so satisfying that I've
worked that control into the way I operate (when I think of it).   I bet
it's wasted on a lot CW ops because it is slow and awkward to employ.

Here's an ergonomic issue:  I sometimes wonder if the Notch switch could be
changed such that it goes into the Manual Adjust mode with a PUSH of the
Notch button, rather than requiring a HOLD because, for whatever reason, my
first attempt at using the Notch button invariably is usually wrong, and
besides my way is faster.

Gary, VE1RGB

Re: [Elecraft] International Shipping Charges!!??!!

[Nidge (Nigel Smith)]

Thanks for all the replies on this one.

I have gone through the tarrifs on the website and the cheapest postal 
charge for
sending a $2 bag of panel screws is around $35 up to $88

The MCU is the same price, and both combined incurs the same charges.

I think I'll contact them direct as I recently ordered a replacement optical
encoder and that was only $10 for shipping.

Once again thanks to all who replied on and off the reflector.

[ab2tc]

On the K3 what would be the approximate setting for 10dB compression?

No. This question comes up once in a while. Lyle made a couple of

and

http://www.mail-archive.com/elecraft@mailman.qth.net/msg62885.html

Perhaps it's "on the list" for future consideration.

Re: [Elecraft] International Shipping Charges!!??!!

[David Christ]

Don't what methods Elecraft is willing to use, but if it fits in a 
9x11 inch envelope and weighs less that 4 pounds you can send it by 
International Priority Mail for about $14.00.  They have a small box 
at that rate, too.  We have sent everything from cake frosting to LCD 
keychains to Norway that way.  Generally takes about 5 days.  Larger 
boxes with a 20 pound limit are $25 and up to about $55.00 for a box 
not quite the size of a K3 kit as I recall.  All a bargain when 
compared to the parcel post rates.

Actually they have the same service domestically running from $5.00 
to $14.00 or so.  Weight limit here is 70 pounds as I recall.  Can be 
cheaper than UPS or FedEx.

Disclosure:  I neither work for nor own stock in the USPS.  I do 
however use their services on an almost daily basis -- generally 
incoming.

> It very effectively cuts out the background blower noise

Some of the major causes of audible background noise are 1) working too 
far from the mic; 2) running the mic gain too high; 3) using too much 
compression/processing; and 4) not rolling off the low frequencies. 

In a noisy environment, it always helps to work close to the mic. It is 
ALWAYS good practice to use the minimum mic gain needed to get good 
modulation, use no more than about 10dB of compression/processing, and 
roll off the low frequency content. It's good engineering practice for the 
highest quality broadcast stations, and it's good practice for ham radio. 

Indeed, the only difference between what's right for broadcasting and for 
ham radio is WHERE to cut the low end and HOW MUCH money to spend on 
compression/processing. Many years ago, I sold processing systems for 
broadcast stations that cost upwards of $10K in today's dollars, and I 
helped the chief engineers of those stations adjust them. I suspect that 
W8JI and K4TAX have similar experience. Before I spent ANY money on an 
outboard box for a ham rig, I would first follow all of those elements of 
good engineering practice.

[Elecraft] RX/TX antenna switching

[Fred Lauricella]

I asked the same question before.

1. You cannot use split to do it. If you try in split you will find there is
no way to have Ant 1 on Receive and Ant 2 on xmit
2. I email Elecraft support directly and the answer was it was only possible
if you add the option with the receive antenna connector on it. I think it
was about $100 usd.

If you do finds a way pleas post it. Others would like to do the same.

Re: [Elecraft] W2IHY 8 band equalizer and EQ Plus

[Lance Collister]

Hello Ron,

I use a W2IHY 2 band equalizer and noise gate with my K3 and am VERY PLEASED 
with 
the performance.  I highly recommend it!

I don't use it for trying to customize my transmit audio fidelity or anything - 
I 
think you could do that very successfully with the K3 adjustments, if you 
wanted 
to.  As a point in fact, I have never changed my K3 audio output settings at 
all.

The reason I use the W2IHY unit is for the excellent noise gate that it 
provides. 
  It very effectively cuts out the background blower noise, and I get excellent 
on 
the air reports with it.  When I acquired my K3, I tried to use the noise gate 
built into the K3 so I could keep the W2IHY unit connected to my old IC746. 
However, I could not seem to adjust the K3 noise gate to avoid getting reports 
of 
audio distortion :-(  So, reluctantly, I had to disable the noise gate in the 
K3 
and return to the external W2IHY unit.

Best wishes for success!  GL and VY 73, Lance

OUCH!  Something is wrong -- hopefully it is not your location. :)

If I were you, I would email sa...@elecraft.com and ask them. While
you might be better off looking for local source for the screws,
you're stuck getting the MCU from Elecraft, and they are in the US.

Re: [Elecraft] k2 headphone jack

[Tom W8JI]

<>

I use the line output for my computer, including sound 
recording. That way radio audio level settings never affect 
digital mode decoding.

I use the rear panel speaker out for my headphones or 
speaker, and have a desk mounted switch that lets me use 
multiple headphones on any audio channel. Any desk anywhere 
can hear any radio any time no matter what or who is using 
the radio. In the contest barn 5 people can listen to the 
same channel, or all on different channels. Since the K3 
speaker audio out is low impedance, and I bridge in with at 
least 160 ohms of load impedance, audio level does not 
change no matter how many phones bridge in.

To get speaker output I have a fader control and a mono amp, 
a cheap MFJ616. The fader moves the 616 to either left or 
right line, since I do not have stereo speakers.

ALL of the line taps, and the lead to the computer, are 
isolated by transformers to prevent ground loops (aka Pin 1 
problem) .

If there is general interest I could put up a schematic, but 
it's a simple clean system that has great flexibility and 
never requires moving plugs. You can see the audio boxes at:

http://www.w8ji.com/my_shack.htm  for the house station.

http://www.w8ji.com/contest_station_w8ji.htm for the contest 
station

Since buss impedance is high normal CAT-5 cable makes a 
great audio buss. Each station, except the one feeding the 
buss, is isolated by transformers.

Before you do, I suggest that you carefully check to see if it conforms to 
AES48 (the "pin 1 problem" Standard. Most stuff like that does not, and any 
box with a pin 1 problem is likely to suffer from hum, buzz, and RFI. Look at 
the input and output jacks carefully -- if they are screwed down to the 
chassis, they don't have a pin 1 problem. If they poke through the chassis on 
holes that are larger than the jacks or are insulated from the chassis, they 
DO have a pin 1 problem. 

The most dependable mfr in that regard is Rane, and they have a very nice 
headphone amp.

Re: [Elecraft] k2 headphone jack

One of the things I plan on doing is getting a simple 4 output headphone amp 
from ART ($65).
Plug one or 2 pairs of headphones in, and output another to my computer, and 
another to a real amplifier/speaker setup.

That way I never have to unplug the set to have an output to my computer for 
Data or voice.

That jack gets a lot of wear for those of us who constantly switch
between headphones and speaker. I don't know if there's a better one
available but when I replaced mine I also wired a speaker/headphone
switch into the circuit. I mounted the switch on the back panel in the
unused XVTR OUT port rather than drill a new hole. 

So now I can leave the headphones plugged in all the time and just use
the switch to go between speaker and headphones. It is also a lot more
convenient than plugging and unplugging all the time-- just reach back
and toggle the switch.

Re: [Elecraft] k2 headphone jack

[drewko]

That jack gets a lot of wear for those of us who constantly switch
between headphones and speaker. I don't know if there's a better one
available but when I replaced mine I also wired a speaker/headphone
switch into the circuit. I mounted the switch on the back panel in the
unused XVTR OUT port rather than drill a new hole. 

So now I can leave the headphones plugged in all the time and just use
the switch to go between speaker and headphones. It is also a lot more
convenient than plugging and unplugging all the time-- just reach back
and toggle the switch.

Re: [Elecraft] RX/TX antenna switching

[Kjeld Holm]

Hi Jon,

I **think** I have seen on this reflector that you could assign VFO A to
antenna 1 and VFO B to antenna 2 and then use SPLIT to do the job. I have
not tried it out myself and I do not have time to do it right now.

I have the antenna tuner with 2 antenna inputs, but not (yet) the KXV3. Is
it possible to automatically switch between ant 1 for tx and ant 2 for rx?
I'm not talking about the subreceiver here.

[Elecraft] K3 Speaker

[Edward Cole]

I found the internal speaker sound a little harsh for my tastes (have 
not equalized the audio), but I have an external 12-inch speaker that 
sounds fine (1950's era National Radio speaker).  Sound in my Sony 
MDR-V600 headset also fine.  I probably will never use the internal 
speaker either in the shack or portable (where headphones are common).

The only thing I don't care for on the K3 is the speaker audio for voice.
Most everybody else I know does not have a problem with it. And I don't
anymore since I operate 99% CW at this time.  The K3 is the only HF/6m XCVR
that I've never regretted getting. The build quality, the company leadership
and location, the support from the company, the dynamic presence of K3
enthusiasts on the internet forums and email reflectors are things that all
make something that nobody can touch right now.

Re: [Elecraft] K3 RF Gain calibration

[Ian Maude]

OK, here is the heads up.

Mea Culpa (as usual :) )

What I had done before was to use CWT and spot to zero beat the signal from
my XG1 and then switch off CWT.  I now assumed the signal was centred.  This
does not appear to be the case.  I tested this with all 3 versions of the
Utility and got the same result.  Then I did it manually, centering the
signal by ear et voila!  It now looks and feels right :)

Re: [Elecraft] [K3] Line in / out socket failure

[Stewart]

Good idea Brendan, however I am trying to reduce the number of interconnects
in the shack, not increase them. I recently went thru a tidy up and get rid of
unnecessary cabling in the shack exercise...

I will have a look at the jack socket positioning on my K3 as you mentioned.
