If I set the NB on per a band, then any time I switch bands I

to turn it back on.
Any way to make the NB switch "sticky"?
Any info would be appreciated.
Thanks.

Thanks to all who have responded.  I'll check it out as soon as I finish
setting up the station after a major downsizing move (the living
quarters, not th station! ).

Gary,

You should not have mic bias set on for that microphone element and
since that is a low output element, the mic gain range should be set
to
high (FP.H. if you are connecting to the Front panel jack, otherwise
RP.H).

To set up the mic gain, put the K3 into TX TEST and initially set
the
mic compression to zero.  Then adjust the mic gain to produce 5 to 7
bars on the ALC display.  After than, set the compression as you
desire
(listening with headphones to the monitor may help you determine the
correct setting).

You may try doing the Reference Oscillator calibration.  Strange and
unrelated as it may seem, I have seen that clean up distorted SSB
signals.

The reverse beacon network is really neat.

http://www.reversebeacon.net/

You can set up to see a map (in the show/hide options) and you can set up to 
look for specific calls. Great when you are waiting for that DX to come on and 
to see where they have propagation.

To see how you are doing, set your call in for the DX stations call and then 
call CQ.

[Elecraft] Elecraft CW Net Announcement

[kevinr]

Good Evening,
A rare sunset (for this time of year) is just about over.  If only 
this had happened a week ago.  Then I would have had a better chance at 
seeing another comet.  But the next one should be even better and during 
my dry season.


   After a very mild February I am back to snow and cold again.  A 
little new snow each day in a variety of mixes.  The last bunch 
yesterday was in the form of "ball bearings"; spherical ice in a range 
of sizes.  It is very dense and loud :)


   Hopefully propagation will be better than it has been throughout the 
week.  One would expect the ionosphere would be better for our purposes 
after a solar event.  Maybe the sun is not yet finished with us.


Please join us tomorrow afternoon and evening.

1) Hail signs  (first letter or two of the suffix of your call)
2) NCS help  (as well as QSP/QNP  help)

Sunday 2200z (Sunday 3 PM PDT) 14050 kHz
Monday 0100z (Sunday 6 PM PDT)  7045 kHz

   Stay warm,

were still not very good.  There had been a solar storm earlier and the 
after effects were apparent.  KS7D was my DX for the day.  Just good 
enough to grab him but not much else.

Re: [Elecraft] K3 RTTY bandwidth already too narrow?

[Ed Muns]

Comments below, in line...

K9OM wrote:

The K3's bandwidth (prior to the DSP-281 firmware, about to be released to
Beta) is on a par with all other radios' internally generated FSK.  And,
this bandwidth is significantly wider than it needs to be.  The wave-shaped
or filtered FSK signal in DSP-281 is an optimum balance between bandwidth
and intelligibility.  In other words, it is possible to be too narrow.
Thus, the new K3 FSK bandwidth occupies only enough bandwidth as needed for
reliable communication.  Hopefully, other manufacturers will follow suit.

I suspect this is not due to the (current) K3 FSK signal being inherently
narrower than the other station's radio, but more likely due to improperly
adjusted AFSK or an improperly-driven linear amplifier.  If the other
station properly adjusted his transmitting system I think you'd find about
the same bandwidth in your signals.  And, perhaps the other station chooses
to tolerate your QRM more than you choose to tolerate his!

Two points here:

1.  The K3 KFL250A is actually 370 Hz wide at the -6 dB points.  The KFL400A
is 435 Hz.  There is no reason to have both filters in the same receiver.

2.  The IF bandwidth is a function of the cascaded bandwidths of the crystal
and DSP filters.  For example, the resulting bandwidth of the KFLA250
(actually 370 Hz) and a DSP of 350 Hz, will be something less than 300 Hz.
The KFLA400 (really 435 Hz) and DSP of 400 will be nearly 300 Hz.

They may also be using a K3.  There are more than 7000 out there!

Not yet, unless the other station is mis-adjusted or defective, at least for
the vast majority of RTTY radios in use.

Yes, it is true that if you transmit a substantially narrower signal than
your neighbors on the band, that you are subject to more QRM from them than
they are from you.  This puts pressure on other manufacturers to follow suit
and narrow their transmitted signals down to the optimum needed for reliable
communication.  This is better than allowing the K3 to be adjusted wider so
as to "defend" your  run frequency.  ;>)

Absolutely.  A parallel history exists with CW bandwidth (key clicks) across
various manufacturers' radios.  Elecraft rightly chose not to allow user
adjustment of keying rise/fall times such that key clicks can be created.
They are about to do the same for FSK bandwidth by narrowing the K3 FSK
bandwidth to only what is needed.

Viewing K0SM's excellent work, it is easy to see that higher power FSK
signals are disproportionally worse than low power.  This is because the
skirts of the unfiltered FSK transmissions are not linear, but flare out
considerably.  Properly filtered FSK bandwidths are similar to good, and
properly adjusted, AFSK bandwidths.

[Elecraft] For New (ALL) Hams, How to Tell What an Amp Will Do For Your Signal

[Dr. William J. Schmidt, II]

An even better methodology for determining if the power, antenna, and
propagation is good for the type of operating you do is to use the wealth of
internet-connected receivers around the world to see how your signal

[Elecraft] Elecraft SSB net announcement

[Phil Shepard]

The weekly Elecraft SSB net will meet tomorrow (3/24/13) at 1800Z on 14.3035 
MHz +/- QRM. I will be the net control from western Oregon. Let's hope 
propagation is better.   See you there.

Re: [Elecraft] K3 SSB complaints I am getting

[Don Wilhelm]

Gary,

You should not have mic bias set on for that microphone element and 
since that is a low output element, the mic gain range should be set to 
high (FP.H. if you are connecting to the Front panel jack, otherwise RP.H).


To set up the mic gain, put the K3 into TX TEST and initially set the 
mic compression to zero.  Then adjust the mic gain to produce 5 to 7 
bars on the ALC display.  After than, set the compression as you desire 
(listening with headphones to the monitor may help you determine the 
correct setting).


You may try doing the Reference Oscillator calibration.  Strange and 
unrelated as it may seem, I have seen that clean up distorted SSB signals.

@ Kent,

That's about where I set it from around page 5 in the manual. I 
doesn't show up very well with the change in voice as I talk but I've 
tried to keep it to the left of the first large markers on the CMP & 
ALC graphs

@ Matt,

Yes, I need to find someone to help me that way. Don't know who they 
are yet, don't get on SSB enough to know a lot of the people 
close-by.

What do you mean the fixed gain set to RP.H?

And thanks for the replies, I'll get this right sooner than later!

Re: [Elecraft] K3 SSB complaints I am getting

[Matt Zilmer]

One idea is to find someone within easy contact distance that has a
scope or panadapter, and ask him/her to snapshot your spectrum.  If
the Tx is flat-topping, it would show in the spectrum.

Generally, I run the MIC GAIN at 12-15 here, with the fixed gain set
to RP.H.  This is with a Heil Goldline using the narrow element most
of the time.

[Elecraft] K3 SSB complaints I am getting

[Gary Smith]

I have a K3 and my antennae are 350 feet from the QTH. I run 99.9% CW 
and rarely ever get on SSB, about the only time I do so is to join in 
with a nice net on 160M & that makes it twice so far this year that 
I've been on SSB. Both times I have been told my audio is broken up 
and the latest description is "It sounds like its flat-topping". When 
I listen in the monitor I sound as good as I'd expect when listening 
to my own voice; doesn't sound like me but its not obviously 
distorted to me either.

Mic gain is set at 30, compression 7. I've tried other settings like 
zero compression and running the mic gain so low my LP-100A wattmeter 
showed 200W out on peaks from an Alpha amp. I have no complaints from 
my CW signal. 

I'd like to have a scope or monitor to view my signal but I don't so 
I need to uncover this curiosity without nice spectrum gear to help 
me.

[Elecraft] K3 front panel mic audio and monitoring...

[zen...@netspace.net.au]

Hi Iain,

Just to let you know that I've noticed the same issue on my K3 #5102. 

It's present only when I have the front panel mic socket active. When I use the 
rear panel mic input with my headset, the problem is not there. 

Like you, the problem increases as compression is increased. It's not dependent 
on the mic I have connected to the front panel mic connector. MIC + LINE in is 
OFF. 

I wondered if this was some internal feedback associated with the audio amp 
chain connected to the front panel, but I don't know. I also wondered if it 
might be RF, somehow finding its way into the front panel audio chain, but not 
the rear?  

I haven't found a solution. If you do, please let me know. 

73, 
John

[Elecraft] K3 RTTY bandwidth already too narrow?

[RLVZ]

I understand the desirable effects of  reducing bandwidth... but sometimes 
I wonder if the K3's transmit bandwidth  on RTTY is already too narrow.  
Case in point: I enjoy operating a lot of  RTTY contests, but even when I'm 
running 1,500 watts... I continually have  stations that move in real close to 
me and cause me a  tremendous amount of received interference.  (I often 
have to QSY  which is frustrating when I've got a nice run taking place)  And  
that's when I'm running my receive filters tight, such as: 250hz roofing  
filter with DSP filter set at 350hz.  (though I prefer to use my 400hz  
roofing filter with a 400hz DSP setting as it copies signals better)  So it 
seems 
to me that: 1) either their receiver selectivity  is better then that of my 
K3... which is unlikely, or 2) my K3 is already  transmitting a much cleaner 
signal then theirs.  If my K3 transmit signal  is already much cleaner then 
theirs, then I'm going to receive even greater QRM  if I narrow my K3 
transmit bandwidth further.  Which is why  I sometimes wonder if my K3 transmit 
b
andwidth isn't already too narrow.   Again, I appreciate the effort to 
reduce bandwidth as it's a good  thing, but more effort needs to be made for 
this 
to happen on a  global scale.  
 
I like the idea of stations with BIG bandwidths and  Key Clixs to be 
penalized or disqualified.  But that's unlikely to happen  with any regularity.

Yeah but they don't mix  the processor with it nor does the Mic Gain 
usually have a lot of  difference, which is of course why they do it that 
way and why most of us  contest guys and gals use FSK not that it is 
better but its easier.   They also don't shape the FSK or AFSK if you 
would rather either.   But they could.

As bad as the FT-dx3000, its  transmit phase noise (about -100 dBc at a 1 
kHz offset) is still nowhere close  to the interference from an (continuous 
phase) FSK signal, whose keying  sidebands are in the region of -60 dBc at 
the same 1 kHz offset from one of  the FSK tones.

You might be confusing the transmit phase noise with the  poor reciprocal 
mixing (-82 dBc at 2 kHz offset) in the FT-dx3000.  The  latter only affects 
the owner, not the other occupants of the band.  But  even that number is 
still dominated by FSK keyclicks from a signal that is 2  kHz offset away 
(although not by much).

This rings a bell with me, but it's way back in the past so my memory could
be wrong ... Do you have MIC+LIN IN turned on ? (sorry I'm not near
the rig at present so the exact terminology may be incorrect). If so try
turning it to just MIC on and see if the issue is solved.

Subject: [Elecraft] K3 Mic noise while monitoring eq.

Hello,

While trying to adjust the mic equalisation I am getting a continual low
level high end electrical noise, like whistle or very slight feedback
through while monitoring on headphones or speaker.

With more compression it brings it out more obviously but it is there
with no compression.
It is there even on low mic gain but much less.

It even persists even with no microphone, data lead or cables plugged in.

I have unplugged EVERYTHING apart from the power, put monitor speaker
on, and PTT and it is there. At zero mic gain no noise but it rises as
the mic gain does.

If I cut the extreme high end it goes a little but I need some high end
boost for my mic.

Its not to horrendous, its only just perceptible I shouldn't think it
wouldn't carry through to audio with a 2.7Khz bandwidth but I cant be sure.

Can I just assume its just internal noise being picked up on the monitor
amp or do I have to worry about my TX audio quality?

Has anyone else noticed this effect? Do I have duff mic pre-amp
shielding somewhere?

This rings a bell with me, but it's way back in the past so my memory could
be wrong ... Do you have MIC+LIN IN turned on ? (sorry I'm not near
the rig at present so the exact terminology may be incorrect). If so try
turning it to just MIC on and see if the issue is solved.

Re: [Elecraft] OT: For New Hams, How to Tell What an Amp Will Do For Your Signal

[EricJ]

In fact, the whole concept is codified in FCC Part 97

§ 97.313   Transmitter power standards.

(a) An amateur station must use the minimum transmitter power necessary 
to carry out the desired communications.


Sometimes that's 500mw, sometimes it's a lot more.

Ultimately, the objective of this hobby is communication. If you can 
communicate at only 500 mw, do so; in fact, the law requires it. If you 
need 500 watts, you should do so. Not to means you fail at the most 
basic objective of the hobby.


90% of the time I'm CW QRP. The rest of the time I have my K2/10 (SN 
567) cranked to the 15 watt max.

That's a good resource but it doesn't tell the whole story.  An amplifier
will give you around 10 db improvement in signal on the other end.  That's
more than the difference between a dipole and a five element monobander.  As
little as 3 or 4 db will make a significant difference when competing
against others in a pileup, and of course as little as 2 db can make the
difference between no copy and clear copy if your signal is right at the
noise level.

http://www.ab7e.com/weak_signal/mdd.html

Hams have turned their noses up at amplifiers for decades, but the reality
is that an amplifier and a decent vertical is often a more cost effective
way to put out a good signal than is low power to a tower and big antenna
... especially if you live in a low noise area where you don't need lots of
discrimination to hear DX (and even then there are compact receive loops
that make possible alternatives).

I can agree with all of that Ron, and in fact it may surprise many that

No argument Dave.

Of course that's a different situation from listening to a signal on a clear
frequency.

That's why I don't join pileups calling DX and you'll find me on the WARC
bands during contests.

And I know a lot of other Hams who operate just as I do, transmitting only
on clear frequencies. Our sort of operation eliminates the need to have a
big signal that can be copied through someone else's big signal.

The beacons demonstrate just how little power is necessary to work the world
on a clear frequency.

I guess I wasn't particularly clear, or maybe I just didn't say it often
enough.  If you are competing against other hams, such as calling CQ in a
contest or calling DX from within a pileup, EVERY db counts no matter how
good the propagation is.  An amplifier will often win the day for you even
if you can hear the other guy while he's running QRP.

The same situation exists if it is noisy on the other end of the path, where
as little as two db will make the difference between clear copy and no copy.
Check the files on my website if you don't agree.  The problem is ... the
noise level on the other end may be significantly different than the noise
level on your end.  Just because you can hear him doesn't mean he can hear
you.

More importantly, propagation doesn't open up to the same path loss each day
... some days 5 watts gets the job done and some days even 1500 won't cut
it.  And just because you can hear F5XXX running 5 watts doesn't mean that
you can hear PA3YYY unless he's running 1500 watts.

My point is that EVERYTHING is situational and generalizations don't do
newcomers many favors.

I pointed out the beacon resource as a good example of how often that

Otherwise we would not have QRP enthusiasts using simple verticals
with DXCC awards.

I liked the idea that new Hams can listen to the beacons themselves

Re: [Elecraft] OT: For New Hams, How to Tell What an Amp Will Do For Your Signal

[David Gilbert]

Which has exactly been my point all along.  Ham radio is situational ... 
sometimes an amp is a waste of money and coal, and other times it is a 
necessity.  What you experience listening to beacons may be the same as 
what you find chasing a random contact on a clear band, but it is not 
the same as what you experience in a pileup, or in a contest, or when 
the guy on the other end has a lot of noise.

If your operating style is to contact stations when signals are

enough.  If you are competing against other hams, such as calling CQ

The same situation exists if it is noisy on the other end of the path,

you.

More importantly, propagation doesn't open up to the same path loss

That's a good resource but it doesn't tell the whole story.  An 
amplifier will give you around 10 db improvement in signal on the 
other end.  That's more than the difference between a dipole and a 
five element monobander.  As little as 3 or 4 db will make a 
significant difference when competing against others in a pileup, and 
of course as little as 2 db can make the difference between no copy 
and clear copy if your signal is right at the noise level.


http://www.ab7e.com/weak_signal/mdd.html

Hams have turned their noses up at amplifiers for decades, but the 
reality is that an amplifier and a decent vertical is often a more 
cost effective way to put out a good signal than is low power to a 
tower and big antenna ... especially if you live in a low noise area 
where you don't need lots of discrimination to hear DX (and even then 
there are compact receive loops that make possible alternatives).

Re: [Elecraft] Filter help

Arie,

Changing the filter width in the Main RX does not change the filter
width in the SUB RX.

To change the filter width in the SUB RX you must HOLD the B SET
button.  You will see B SET displayed in the display.  Using the same
method as with the MAIN RX adjust the width and then HOLD the B SET
button again and you will have the SUB RX Filter that you want.

When working split with the K3, I usually set the SUB RX filter a
little wider than the MAIN RX filter, so I can hear more band width
in a pile up

Re: [Elecraft] OT: For New Hams, How to Tell What an Amp Will Do For Your Signal

[Vic, K2VCO]

Funny -- one guy says "get an amp, it's 10 dB!" Another says, "don't 
bother, it's only 10 dB."


The truth is, it depends on what you are trying to do with your radio. 
If you are a DXer, especially on 160/80 meters, then even 1 dB may be 
the difference between getting a QSO and getting a "?" from a DX station.


If your operating style is to contact stations when signals are 
relatively good, then who cares if you are S7 or S9?

Re: [Elecraft] kx3 and hdsdr

It doesn't work very well for me, on Windows 8. Omnirig talks to the KX3, no problem, as verified by 
running the Omnirig client. But HSDR stops talking to Omnirig after a few minutes. Nothing but a 
reboot fixes it. Makes HSDR unusable for me.

Re: [Elecraft] OT: For New Hams, How to Tell What an Amp Will Do For Your Signal

[Edward R Cole]

I ran my K3/10 (12w max) for about a year without an amplifier and 
had good success getting out on SSB (CW is way easier so probably an 
amplifier is less needed).  I have checked into the Elecraft SSB Net 
several times with 12w using either the K3/10 or the KX3, 
barefoot.  I do use a Hygain TH3mk4 3-element yagi at 50-feet on 20m 
so that provides about 6-8 dB gain.


It seems there is a good path between me and NS7P, and Phil hears 
pretty good with his setup.


I have operated on 80m SSB on nets here in AK and had good luck 
running only 12w on an inverted-V.


But if conditions are not particularly good, running 270w on 20m does 
help (13.5 dB or little over 2 s-units increase).
On the whole, 100w seems a good level since so many HF rigs run that 
and get out OK.  I suspect the new Elecraft KXPA100 will be very popular.


Of course during DX pileups or contests having a big signal really 
makes it.  For instance, I run 125w with a 6-element yagi on 6m and 
makes working an opening much easier when folks can hear me well (I'm 
the "DX").  When I finish the 1100w 6m PA I expect that will make 
things possible without openings (using eme or ms, that is).
