Re: [Elecraft] K3 - Tx power in digi modes

 About to (finally) try out some RTTY/PSK31 using soundcard AFSK A/DATA A
 modes. Intuitively was going to run at reduced power being 100% duty cycle
 but have read in a couple of places (not the manual..) that you can run
 RTTY at full power (100w). Is this right and presumably it applies as well
 to PSK?
 
 
The K3 is rated for 100W key down for 10 minutes, Eric has actually stated
this, so you should be OK to run RTTY at that power. Having said that, I've
noted PA temperatures in the high 50s after shorter periods and about 50W
power, so I personally wouldn't want to try it. But that's what the spec
says. I'd certainly expect the fans to be going full blast at that power.

It really shouldn't be necessary to run PSK31 at such high power as most
other stations use 20 - 40W. Having said that, I have inadvertently
discovered (due to the power control issue discused at tedious length in
other threads) that the IMD is not unacceptable at 100W peak. At that power
level the K3 power meter will be showing 3 - 4 blobs while the signal is
modulated. The problem currently is that you can easily overdrive the PA
because the K3 can't be relied on to limit the power to 100W peak just
because you've set 100W on the dial. So to be on the safe side - especially
if you don't have a separate IMD meter to monitor your signal - I'd
recommend aiming for no more than 50W peak, which should show about 20W
average on a modulated PSK signal.

[Elecraft] K3 feature request - I want Ducking!

Hey troops,
 
I had an idea last night while in CW QSO with my K3.  I've noticed that
I always turn the AF gain down when I send CW.  I have the side tone
volume set to just the right level for the Spot function to work, but
when I send CW I want to greatly reduce the distraction from the
receiver.  I still want to hear it, but not be distracted by it.
 
That got me thinking about ducking.  Boy, would it be cool if the K3
would duck the receiver under the CW side tone.  I'd want it to be
engaged only when sending (not for spot) and I'd like the AF gain
reduction to be adjustable through a menu setting.
 
I guess another way to implement this might be to have the side tone
affect the AGC so when I send, my RX responds as if it were a real
signal and the AGC kicks in to quiet the receiver.  In this case, I'd
want to set the amount of gain reduction and whether to use Fast or Slow
recovery.

[Elecraft] Filters and the KRX3 vs Main

2009-01-20 Thread AB3EN


I have the KRX3 installed and up and running. Really slick. 

Question: 

I have the 2.8 filter on the sub-receiver KRX3 and the FM, 6kHz, 2.8 kHz,
and 1.8 kHz on the main. Is there any advantage to having the same set in
the KRX3 as the main?  It would appear that the 2.8 kHz in the KRX3 works
well, however I am a little unsure of how to invoke a larger or smaller band
pass on the KRX3 without changing the setup on the main. Help is always
appreciated.

Great radio! Lots to learn and never a dull moment. Thanks Elecraft, and
thanks to all the folks on the reflector. 

Thanks
AB3EN

I know I could replace the element with one from Heil, but I would prefer to

Re: [Elecraft] K3 feature request - I want Ducking!

2009-01-20 Thread Erik N Basilier

Interesting idea Keith!

I must admit that I too have often been turning down gain controls while 
transmitting, not only on the K3, but even more on other rigs. At other times I 
have been using semi-QSK with a *LONG* timeout, even though the rig including 
amp can handle full QSK. The reason is that my aging brain finds it harder 
every year to focus on a task. Sending CW (my favorite mode) requires my 100% 
attention, and *any* distraction can make me mess up: other stations received 
within the passband, band noise, fan noise, relay clicks, and even hard edges 
on the side tone. I am so happy that the K3 doesn't have the relay clicks of my 
old 1000D, but under some circumstances its QSK/side tone have given me hard 
edges although that is normally not the case. The K3's selectivity is a great 
blessing, and although I can copy a single signal among several in a wide 
passband, I tend to reduce bandwidth during a QSO so that I can transmit 
without hearing other stations. I recently got a nice headset that blocks 
external sounds for the purpose of blocking out the vacuum relay clicks and fan 
noise from my amplifier. 

Your automatic ducking of the AF gain during transmission would be a welcome 
option that I would probably end up using sometimes if it were implemented. I 
guess the ducking as used during full QSK could use a delay equal to the 
semi-QSK delay setting. For use with semi-QSK perhaps one would want to use a 
shorter time constant for switching to receive and a separate longer time 
before receive gets full gain.

Another idea: Since much of the distracting noise between characters can be 
eliminated by using a really narrow bandwidth, how about a new twist on Dual 
Passband: transmit full QSK with the very narrow receive bandwidth and open up 
the bandwidth to 500 Hz or so after a delay set by the semi-QSK delay?

73,
Erik K7TV

Re: [Elecraft] D-104, only slightly OT

2009-01-20 Thread David Pratt

The D-104 is an excellent microphone for the K2 (and K3), Tom.  Because
the ceramic/crystal element is high impedance, your best way of testing
it is to wire it up and try it.  The pre-set gain control will need to
turned fairly well down.

Connect it to the 8-way plug:
WHITE (or CLEAR) to pin 1 (audio)
RED to pin 2 (press to talk)
SCREEN to pin 7 (ground)

Re: [Elecraft] D-104, only slightly OT

2009-01-20 Thread Paul Christensen

 I know I could replace the element with one from Heil, but I would prefer 
 to
 keep it as original as possible (it does have the preamp in the G stand
 base).

Tom,

Odds are the crystal element is still in good shape, provided it has not 
been subjected to a high humidity environment over an extended period of 
time.

Also, anyone contemplating the use of the D-104 with the stock Astatic amp 
should consider an alternative buffer amp.  The input Z to Astatic's 2-stage 
preamp calculates to 470K-ohm -- way too low for a crystal cartridge.  The 
crystal cartridge should see a termination of no less than 5 megohm, and 
preferably greater than 10 megohm in order to preserve reasonable low-end 
response.

The series capacitance from a typical crystal cartridge is anywhere from 
800pF to 1600 pF.  Calculate the - 3dB turnover point into various 
terminating resistive values and you'll see why it's important to completely 
unload the crystal cartridge.

For simplicity and excellent performance, I favor a single transistor JFET, 
configured as a near unity-gain source-follower.  The web is full of FET and 
op-amp designs for the D-104, but nearly all of them suffer from inadequate 
design, particularly with respect to crystal cartridge loading.  Most 
designs I've seen attempt to bias the FET as the analog of a grid leak 
resistor used on a vacuum tube grid.  As a source follower, the FET is 
completely self-biased when the correct source resistor value is used.

The D-104 crystal cartridge can be attached right to the FET's gate with no 
other components necessary.  For isolation, I add a 5-meg resistor in series 
with the gate, but this is not strictly necessary.  If gate failure is a 
concern from static electricity, some ops have used a 10-megohm resistor 
from the gate to ground in an attempt to bleed static build-up..  I've never 
found this to be necessary.

If all of the above sounds like too much work, simply insert a 10-megohm 
resistor between the D-104 cartridge and Astatic's 2-stage preamp.  Signal 
to noise and distortion performance will suffer, but at least the cartridge 
will be unloaded.  The Astatic preamp can more than compensate for the loss 
in level owing to the use of the series resistor.

When the K3 is configured for ESSB transmit, the D-104 will sound nearly as 
good as an expensive studio condenser or dynamic mic.  As a final footnote, 
I recommend ESSB only for use on uncrowded bands, and when signal strength 
is high.  Otherwise, it's a waste of occupied bandwidth.

Paul, W9AC

Re: [Elecraft] D-104, only slightly OT

Do you have an audio amplifier, a mic input on your sound card or even a
pair of headphones around? Try the mic with them. Any audio in the phones is
likely very low level but you might hear something in the typical 50-ohm
computer or game headsets around today. Some clip leads and a suitable
connector are all you need -- ground and hot lead -- to whatever 

If you have an o'scope, it'll show audio too. 

(Of course you have to make noise near the element ;-)

If you hear or see *any* response from the element, it's likely good. Those
old crystal and ceramic elements tended to work fine or not at all. 

Be sure the amp in the base has a good battery in it: 9V IIRC.

Re: [Elecraft] K3 feature request - I want Ducking!

Ducking is a commercial radio / sound industry technique of attenuating
the music when the DJ talks.  In the old days, the DJ at the radio
station would just pan down the music volume whenever he spoke into the
mic.  These days, recording studios will use a compressor with a
separate trigger (side chain) input.  The compressor is set to attenuate
20 dB or so whenever there is something on the trigger input.  You run
the music through the compressor and feed the voice to the trigger.
Then, when you talk, the compressor is activated, forcing the music to
duck under the vocals.  Close your mouth and a moment later the music
rushes back to full volume.

I agree.  An alternative would be if the printed menu description also
included (in bold) the actual WORDS that the menu abbreviation stood for,
finding the menu you wanted would then be simpler.  As it is now, the

Re: [Elecraft] Future Feature Request

Individually numbering each menu item could prove to be awkward.  If you assign 
numbers 1 through 'n' now, what happens when you insert something later?  It 
gets number n+1 but it may appear out of numeric order as you surf through the 
menu system.  Same thing happens if you move an item around.  If an item is 
deleted or replaced by 2 items, then I suppose you'd have to retire the 
original number.  So instead of a nice clean listing of numbers 1 through N, 
you'd have a sparse list of items 1 through N that probably are not in 
numerical order when you look for them in the menu system.

The Astatic D-104 was designed as a *communications* microphone with a
carefully shaped frequency response for speech and not for extreme high or
low frequency response. 

The graph of the audio response published by Astatic, using the built in
amplifier, shows 0 dB at 1 kHz. Below  1 kHz the output drops off smoothly
to -5 dB at about 200 Hz, then more steeply down  to -10 dB at 100 Hz where
the published curve ends. 

That roll-off is important since excessive low frequency response robs a
signal of intelligibility and punch since the bulk of the energy, but
virtually none of the modulation in the spoken voice is down in those
ranges. 

Above 1kHz, the output rises smoothly to a peak a bit above +10 dB at 3 kHz,
the smoothly drops off to almost - 20 dB at 10 kHz. 

That rising characteristic to a peak in the roughly middle point of the
speech audio spectrum is what made it so effective in communications and
made it so popular.

Re: [Elecraft] K3 feature request - I want Ducking!

No, the manual way to achieve this effect is to turn down the AF gain
while you're transmitting.  Sidetone is still there nice  loud but the
RX audio that you hear between elements is reduced.  When you're done
sending, you reach for the AF gain and turn it back up to the normal
listening level.

Now, imagine it was automatic.  As soon as you send, the K3 turns AF
gain down and leaves it down until a second or so after you finish
sending, then it turns it back up to where it was.  This way, while
you're sending, the AF signal that you hear between dots  dashes is
quieter than when you're just listening.

Is that any clearer?  If not, ask more questions :-)

I still don't understand this notion.  For CW, don't you obtain this
effect simply by turning down the sidetone volume?  On transmit, receive
is already muted.

The K3 will handle 100W for 10 minutes in ... RTTY will be

 Is this right and presumably it applies as well to PSK?

Individually numbering each menu item could prove to be awkward.  If you 
assign numbers 1 through 'n' now, what happens when you insert something 
later?  It gets number n+1 but it may appear out of numeric order as you 
surf through the menu system.  Same thing happens if you move an item 
around.  If an item is deleted or replaced by 2 items, then I suppose you'd 
have to retire the original number.  So instead of a nice clean listing of 
numbers 1 through N, you'd have a sparse list of items 1 through N that 
probably are not in numerical order when you look for them in the menu 
system.

Re: [Elecraft] D-104, only slightly OT

2009-01-20 Thread Paul Christensen

 The Astatic D-104 was designed as a *communications* microphone with a
carefully shaped frequency response for speech and not for extreme high or
low frequency response.

Although the presence rise was a design attribute of the mic, limited 
low-end response was not.  The D-104 was produced in the early 1930s as a 
communications microphone intended for reasonably good, balanced audio 
response in the AM mode -- not SSB.  SSB as used in radio communications is 
a post D-104 phenomenon.  Use of the D-104 pre-dates common SSB use in the 
amateur service by 20 years.

According to Astatic, their 2-stage buffer amp was designed as an active 
impedance transformer as low-Z solid-state devices were being ushered-in 
during the 60s   Astatic never intended for the preamp to be used as a 
power mic device.  It was the Citizen's Band operators who made the added 
gain function popular.  That said, Astatic could have designed a much better 
buffer for the D-104.

 The graph of the audio response published by Astatic, using the built in
amplifier, shows 0 dB at 1 kHz. Below  1 kHz the output drops off smoothly
to -5 dB at about 200 Hz, then more steeply down  to -10 dB at 100 Hz where
the published curve ends.

The typical D-104 with 2-stage preamp is substantially more response limited 
than that shown in Astatic's graph.   The response plot shown in their 
instruction sheet is hardly a scientific measurement and the response can 
vary considerably across cartridges.

 That roll-off is important since excessive low frequency response robs a
signal of intelligibility and punch since the bulk of the energy, but
virtually none of the modulation in the spoken voice is down in those
ranges.

True of weak signal communications.  Not true when the SNR is high - and the 
reason for the disclaimer at the end of my post.  If your theory is correct, 
I doubt Elecraft would have included ESSB as a design feature into the K3, 
The lowest fundamental of the deepest male voice can be measured as low as 
70 Hz -- and is typically 75-85 Hz.  It's not that spoken voice does not 
produce frequencies that low, it's that historically, SSB transmissions have 
been deliberately bandwidth-limited.

 That rising characteristic to a peak in the roughly middle point of the
speech audio spectrum is what made it so effective in communications and
made it so popular.

The D-104 became popular for a variety of reasons including cost, 
aesthetics, availability in the golden age of AM, reasonably good and 
balanced frequency response, etc.

Hi Eric,
Not sure I understand what benefit there would be to open up the bandwidth
when in QSK mode. Since I most likely will be in QSK mode when calling
someone, I would think one would want to maintain the same receive bandwidth
as selected before initiating the call.  
If I need to change bandwidth quickly I use I/II.
 
What am I missing?

I would definitely view it as an option, and I'd want some
configurability to it.

But, with this feature, you'd still be able to run full QSK and hear
between dots.  It may be that really weak stations become harder to hear
depending on how much attenuation you choose to apply to the RX signal.

I'm thinking I may give it a try with my external compressor.  I *think*
I can get it all hooked up.  We'll see.

Actually, as I said, it's quite acceptable at 100W peak, which I have run on
several occasions inadvertently due to setting the power control to 40W and
believing that's what I was getting.

Exceed 100W though, and it rapidly becomes awful.

It would still be a good idea to have some form of IMD monitoring in place

[Elecraft] Another Feature Request

2009-01-20 Thread John Huffman

I'm enjoying my first week with my new K3. 

But, I find some features that I'd like to have aren't there or I don't 
yet know how to do them if they are.

On my K2 I could use my paddle as a PTT when operating SSB using a 
headset.  That was handy.  The paddle was right there.

On my Orion, that same feature is a option on a menu and I was always 
sure to enable it.

I wish the K3 could do that , too.

I know I can use VOX or the XMIT key on the keyboard.  Not so handy.  I 
could rig up another key or footswitch too the PTT on the back of the 
K3, but I'd rather just do it the way the K2 does.

I may be alone in this, but feel better that I got to voice my 
suggestion.  And, like I say, I may be able to do this already, but lack 
the K3 knowledge to get the job done.

Re: [Elecraft] OH! I get it ... I think

Yes, it is to manage the din when operating full break-in mode!

I use QSK because my CW timing gets messed up by semi break-in.  I find
myself waiting for the RX to open back up before I send the next word or
trying to rush things to prevent the change over.

I also send with bugs or straight keys so I need to truly hear what the
side tone is telling me or I'll end up with sloppy CW.  With a keyer, CW
is much easier to send so I can tolerate more RX noise.

2009-01-20 Thread DOUGLAS ZWIEBEL

Wayne said,

My comments:
This request is something I've never heard of and I am having a hard
time imagining an actual use for it.  If you turn the AF down (or duck
it), then they station that you still want to hear must be relatively
loud...or at least above the din.

So in addition to Wayne's suggestion (which I agree with and was
actually my first reaction), how about just turning down the RF gain
for that QSO to the point where the noise (almost?) is out of the
picture but the guy you want to hear, should he break you, is still
audible?

I first started using full break-in many years ago when I was active in
the CW traffic nets.  You need QSK so you can hear the other station
break in for fills.

But I soon became addicted to it for all my CW operating.  I feel like
I'm half-blind when I can't hear what is happening on the channel while

Actually, I think a small amount of gain reduction might go a long way 
toward reducing operator fatigue in a contest, for example, without 
seriously impacting the ability to hear a break.

What's important is that the amount of gain reduction be adjustable over 
a wide range to accommodate the above use as well as for the guy who 
wants it to be a kind of semi-QSK.

I tend to accomplish this by setting the delay such that, the spaces between

use 
it as a method that helps me keep my spacings at the same for letters and words

Re: [Elecraft] K3: ducking this topic

2009-01-20 Thread Erik N Basilier

Douglas,

To avoid bringing down the audio level of the station you are working,
again, the ducking might be better done by automatic change of
bandwidth instead of automatic change of gain setting:

I would be listening around the band with, say 500 Hz, find a station, use 
e.g. CWT to tune properly.
As soon as I call him, my receive bandwidth automatically drops to 100 Hz, 
and stays there until
say 1 second has passed without any transmission from me; then the bandwidth 
widens to 500 Hz again
until I transmit again. Saves the trouble of manual action. If instead I was 
calling CQ, I may or may
not prefer this mode, as it would make me hear the correctly tuned caller 
before I can hear ones
that are off frequency.

Erik K7TV

Re: [Elecraft] K3: ducking this topic

If I manually turn the RF gain down, then I've made it so only the loud
stations are loud to me.  Quiet stations (and the band noise) are all
but gone.  When a loud station appears, I hear them well.  When loud QRM
appears, I hear it well too which is exactly what I want to avoid.

A similar issue exits with auto bandwidth changes.  If the ducking
system narrows the bandwidth to get rid of distractions, that's fine
until QRM appears on your freq. and masks your sidetone.

Instead, I want my RF gain to be high enough so that the weak and strong
signals get some AGC action.  Then, I want the AF gain auto-reduced by
maybe 6-10 dB so that I can clearly hear my sidetone over the RX audio.
With this configuration, I should be able to hear just about anything,
weak or strong, that appears on my freq, but it won't be loud enough to
mask my sidetone.  I'm aware, yet still in control.

Re: [Elecraft] OH! I get it ... I think

2009-01-20 Thread Gary Smith

I'm one who often uses full break-in. There's a lot of reasons to use 
it but it requires certain aspirations depending on situation. For 
instance, here are some pointed examples:

Say you're chasing DX, there are others chasing the same station at 
the same time. Everybody calling needs to leave their call but the 
only way you can tell who if anyone's call is being returned is to 
hear it being returned to you. If you're calling, you can't hear what 
is being returned. But if the DX is not returning a call then either 
they haven't heard one call clearly, they are in the process of 
entering a heard call in their log (and are about to transmit that 
specific call) or you're calling from an area they do not wish to 
cultivate and they heard you but you're not in their hunt.

So you persist in calling but need to listen to the DX stations 
return call to whoever it is going to to know they have made a 
decision as to who to call or that it's still in flux. If you do not 
run full break-in then you become one of those QRMing people who call 
on top of the DX station while they are transmitting. If you can't 
hear the DX station through all the QRM then you shouldn't be calling 
blindly hoping they will somehow hear your call and when the din 
quiets down from the others realizing it's not their call being heard 
and it is your call that you hear them calling.

The latter is possible but not probable. What is more probable is 
they are calling someone else and you've been nothing involved but 
QRM.

Assuming everyone ran full break-in and would listen for the DX 
station in-between dits  dahs, then everybody would immediately stop 
sending when the DX is transmitting and a whole lot more QSOs would 
be made.


Another example is if you are in a 1:1 QSO and you have your RF gain 
set so you hear nothing but your QSO partner, you don't hear all the 
QRN in the background and lets say you converse at conversational 
speed, if the other person misses something they can send a few dits 
and you hear that and you know to stop your soliquy and let them 
interrupt to ask whatever. Maybe they need to answer a phone or 
spouse, whatever... it allows you to do as you would do on the phone 
with someone and say in real time Hold on a moment, I need to answer 
a question or whatever.

If you're in semi or no break in mode, you can keep on sending an 
opus that the other wishes you weren't sending but has no way to tell 
you that.

FWIW, I love QSK that does not pop in-between characters!

KA1J

 From reading the posts about ducking it sounds like
 there are those of you who operate CW in a full break-in
 mode where you hear between code elements.  Is this
 the case?
 
 If so, I can't envision how you tolerate the noise (!) and
 understand why you'd want to lower the level of the din
 between code elements.
 
 Other than the obvious desire to hear a BK between
 code elements, or to hear if the DX station in a pile-up
 has answered someone other than you, what's the 
 reason for using this mode?
 
 Thanks for any enlightenment ...

I can only speak for myself, but I adjust the K3's BW, AGC, RF gain
and AF gain so that the there isn't that much noise at all - so full
QSK is not painful at all, but actually quite pleasant. I suppose such
ducking of the audio could be desirable when when gains are turned way
up in an attempt to copy a very weak signal.

Re: [Elecraft] K3 feature request - I want Ducking!

2009-01-20 Thread Joe Planisky

I like this ducking idea and would very likely use it.  It's sort of a  
'soft' QSK.

I certainly understand the benefits of full QSK operation, but it's  
something that I simply cannot get my brain to cooperate with.  To me,  
operating full QSK with other signals present is like trying to count  
ball bearings with two or three other people shouting random numbers  
at me.  Even without other signals, the rhythmic pulsing of the band  
noise messes me up.   I usually use semi QSK with a 1/2 second or so  
delay, but perhaps with an option for something between dead silence  
and operating volume level, I could train my brain to work full QSK.

 No, the manual way to achieve this effect is to turn down the AF gain

 the

 listening level.

 Now, imagine it was automatic.  As soon as you send, the K3 turns AF
 gain down and leaves it down until a second or so after you finish
 sending, then it turns it back up to where it was.  This way, while
 you're sending, the AF signal that you hear between dots  dashes is
 quieter than when you're just listening.

On p. 29 of the instructions, it states as 6th step:

On the top and bottom sides of the board  near J7 you'll find short  
jumpers.  Install U-shaped wires at both locations.


Perfectly clear...except I missed the near J7 so I made a jumper at

[Elecraft] PR6

2009-01-20 Thread Mike Harris

G'day,

Just received my PR6 (6m pre-amp).  I've set it up for CTRL from the ACC 
socket (Config: DIGOUT 1 - On), that is it is switched on only when 
switching to 6m.  All works very well, I see a 7-8dB improvement in 
antenna noise and a subsequent improvement in received signals.

The 6m antenna was on ANT:2 of the KAT3 when I set it up.  My Acom 1000 
was on ANT:1 and the hf beam.  When I swapped the Acom onto the 6m antenna 
and selected ANT:1 for 6m the RX was deaf!

A whole bunch of testing later I discovered the CONFIG: DIGOUT 1 signal is 
not common to both ANT:1 and 2 you have to set it for each selected 
antenna.  When I set CONFIG: DIGOUT 1 for ANT:1 everything was OK again.

This might be well known, however, I've not spotted it in any 
documentation, certainly not in the PR6 manual, so if it is an 
undocumented feature, beware.

Regards,

Mike VP8NO

Pardon my density, but I can't figure out how to realize the function
depicted in figure 3 of the K3 Owner's Manual: routing a signal from the
ANT2 connector to the KRX3 through the KAT3. I don't see anything in the
FAQ. Can someone, please, tell me how to configure the rig so that K1 and K3
are properly actuated.

Thanks,

Re: [Elecraft] OH! I get it ... I think

2009-01-20 Thread Guy Olinger, K2AV

I'm not sure what the din is, other than what is happening on the 
frequency I am transmitting on. If you don't want to hear the frequency 
between dits, why are you running QSK? Set the hang time to a character or 
word space at your speed (easily done with most contesting programs or 
hardware) and enjoy the quiet. Also turn up the MON setting to where it is 
the same level as signal in your bandpass, and get your AGC contants to 
where you are confortable with the audio levels.

When I'm operating QSK, I don't want the K3 to change bandwidth, level or 
where the AGC was when I hit the key. I operate QSK because I WANT to hear 
my frequency between dits.  What I am listening to within the RX bandwidth 
is hardly knowable by the K3, nor can it know when I am done.  I 
specifically WANT the din between the bits. The din in between is why I 
turned on QSK.

73, Guy

 Yes, it is to manage the din when operating full break-in mode!

 I use QSK because my CW timing gets messed up by semi break-in.  I find
 myself waiting for the RX to open back up before I send the next word or
 trying to rush things to prevent the change over.

 I also send with bugs or straight keys so I need to truly hear what the
 side tone is telling me or I'll end up with sloppy CW.  With a keyer, CW
 is much easier to send so I can tolerate more RX noise.

 -Original Message-

From reading the posts about ducking it sounds like
 there are those of you who operate CW in a full break-in
 mode where you hear between code elements.  Is this the case?

 If so, I can't envision how you tolerate the noise (!) and understand
 why you'd want to lower the level of the din between code elements.

 Other than the obvious desire to hear a BK between code elements, or
 to hear if the DX station in a pile-up has answered someone other than
 you, what's the reason for using this mode?

 Thanks for any enlightenment ...

[Elecraft] all I wanted to do was give PSK31 a try, and now I've got real trouble

2009-01-20 Thread KC9GBX

So I purchased a NUE-PSK modem kit ( I had them do the surface-mount
component soldering), and after I had completed my portion of the soldering,
things
checked out fine.

I also ordered the cable that connects the modem to my K2, but I was
informed that the cable would be shipped separately. After waiting for nearly
a
month without receiving the cable, I decided to make my own. I followed the
generic cable-wiring diagram that NUE-PSK provided in the kit assembly manual.

My crash-scene investigation revealed that I had pumped 13.5 volts from the
modem into the K2's microphone jack, pin 6, which is marked on the K2
schematic as a 5 volt line.

Now, when I push the K2's POWER ON button, I hear an initial relay click,
but that's it!!!
No LCD display, no bar graph, no audio, no band or mode change occurs.

I'm hoping that I only fried the 5 volt regulator, U5, on the Control Board,
but I'm pessimistic by nature! I didn't see or smell any smoke. Any ideas
would be most appreciated!

It's been a great low-power rig for more than 4 years, and I'd sure like to
save it!

Here's hoping, and 73, Jef Fox kc9gbx

Re: [Elecraft] KRX3: configuration for second antenna routing

2009-01-20 Thread Jay Rodaman

It would be great if all you had to do was route a bnc jumper from RX ant
OUT to the AUX ant on the sub-
Receiver and in that way when the sub was active it would use the receive
antenna for diversity
And when inactive it would be the main receiver REC antenna.

Re: [Elecraft] OH! I get it ... I think

2009-01-20 Thread Erik N Basilier

Guy,

Forgive me for putting bandwidth change into the already complex argument,
but since you mentioned it, here is further explanation of my view on that:

When I'm operating QSK I want to hear my frequency between dits
but *only my* frequency. All too easily I make transmission errors
if the radio doesn't do a perfect emulation of a code practice oscillator.
Cranking down the receive bandwidth to 100 Hz during transmission
often brings something close to that effect. In all but the shortest QSO's
I routinely do this manually. It would be great if it could be done
automatically.

If the other station in the qso breaks into my transmission then I welcome
it, even with the stumbling on my part that is likely to result. If I hear 
another
station nearby *while I am transmitting* I see it as a nuisance.

During reception things are a bit different. On the one hand, my copy
will be better if the bandwidth is narrow. On the other hand, another
station may legitimately be calling me slightly off frequency. I am less
embarrassed to miss a character during reception than stumbling
during transmission. Probably in a typical situation the ideal receive
bandwidth during reception is wider than during transmission,
assuming that a small bandwidth is used as the tool of choice to
remove unwanted din during transmission (which does not include
what may be coming from the other station in the qso).

73,
Erik K7TV

 When I'm operating QSK, I don't want the K3 to change bandwidth, level or
 where the AGC was when I hit the key. I operate QSK because I WANT to hear
 my frequency between dits.  What I am listening to within the RX bandwidth
 is hardly knowable by the K3, nor can it know when I am done.  I
 specifically WANT the din between the bits. The din in between is why 
 I
 turned on QSK.

[Elecraft] K2 - Battery needs CPR

2009-01-20 Thread Tom McCulloch

Hi all,


I know, I know... I should have used a trickle charger on my K2's battery 
like the one Don, W3FPR talks about at:  http://w3fpr.qrpradio.com/index.htm 
. But I didn't.  Before I take the easy way out and order a new battery from 
Elecraft (only 30 bucks, so that's not too bad), does anyone have any ideas 
to bring my old battery back to life?

The problem was that I went QRT for a year or so and left the battery 
unattended and now it won't hold a charge.

On the bright side, I'm now building an SLA trickle charger similar to the 
AA Engineering one that Don mentions...there was a QST article on it a 
while back...so that's been fun, but it's not finished yet and my battery 
needs mouth to mouth...

Any ideas would be appreciated.

Thanks,
Tom

Re: [Elecraft] Elecraft K-3 SSB and AM Squelch

2009-01-20 Thread John Petters

Hi Wayne
I'll second that. Dave G4AON kindly sent me an old version of the 
firmware so that AM would work again.  For the K3 to be viable as an AM 
TX it needs to behave the same way as a boat anchor rig. My KW Vanguard 
uses two 6L6s to modulate a 6146B. The modulation is excellent. My 
706MK11 does a very good job on AM also.

Whilst looking at this, could you look again at the FM transmit, which 
sounds woefully thin compared to my rice boxes set on FM narrow. The 
audio has no body and tends to sound snatchy on peaks.
No complaints whatsoever about RX in either mode. Be nice to get the 
Synchronous AM after playing with Dave's Perseus over the internet.

[Elecraft] K3 - CWT ON/OFF change request

2009-01-20 Thread W6NEK

I would like to request that the operation of the CWT function be changed. 
Now when ever I am on CW and enable CWT as soon as I change modes, or switch 
bands, the CWT function is turned OFF.  I would like to see the CWT function 
remain ON until I turn it OFF.  This function can either be global or on a 
per-band basis.  Right now it's a real pain to have to re-enable CWT 
everytime I switch modes, or bands, and return to CW mode.

I know the firmware change request list is very long but I hope this can be 
implemented sooner rather then later.

Many thanks to the Owners/Designers of Elecraft for encouraging it's 
customers to make suggestions and actually implement a significant number of 
change requests.  Elecraft is truly unique in this regard.  Thank you!

[Elecraft] K1 - High current drain on power on

2009-01-20 Thread Ian Nightingale

Hello everyone, I'm sorry to trouble you with something which you've probably 
had posted a thousand times. I'm very new to the hobby and am struggling to get 
the K1 to work.

Symptom: Up power on the current drain is high (as much as I would allow the 
bench supply to give).
This is with just the RF board and front panel connected. Supply is a bench 
supply with 12.5v and max 1 amp.

On my first attempt to use the rig the Q7 on the finals melted. This has been 
replaced but it was clearly the poor recipient of the high current and not the 
cause.

I have carefully checked each component is in the correct place and 
orientation. 
I've checked each solder joint.

What I need are some places to start troubleshooting the issue. Your assistance 
will be greatly appreciated.

flying colors.  However, when I set the AGC Threshold Voltage using R1, the
maximum voltage I was able to reach was 3.67V with the pot at the end of its
range.  I checked this value with both my DMM and the onboard volt meter and
they agreed within 0.07 volts.  Is this an issue since I was unable to
achieve 3.8 Volts?  If so, where should I look for the problem?

Re: [Elecraft] KRX3: configuration for second antenna routing

Brian,

Whether figure 3 is applicable to your K3 or nor depends on how you have 
the subRX antenna connection physically connected.

If you have connected the subRX antenna to the Aux RF BNC connector, the 
configuration shown in Figure 3 is not possible whthout changing the 
antenna cable to the subRX.  With the cable from the BNC to the subRX 
connected, you may choose to connect the subRX to either the main RX 
antenna or the the AUX RF input.

To connect the subRX auxiliary input to the non-transmit KAT3 antenna, 
the TMP cable from the KAT3 to the subRX antenna input must be in place 
(instead of the TMP cable from the BNC).

Factory built K3s with the subRX installed have the BNC cable installed 
and a separate TMP cable is shipped with the K3 to allow the user to 
change to the non-transmit KAT3 antenna.

All of this is explained on pages 24 and 25 of the KRX3 installation 
manual.  The first paragraph on page 25 says it all - only one of these 
options can be installed at one time.

Re: [Elecraft] all I wanted to do was give PSK31 a try, and now I've got real trouble

Jef,

Sorry to be the bearer of bad news, but if you dumped 13.5 volts onto
the 5 volt rail in the K2, it is likely that you have either damaged or
stressed all the components that operate on the 5 volt rail.
That would be Front Panel U1, U2, U3, and U4. It is also possible that
the encoder could be damaged too. Then on the Control Board, U6, U7 and
U8 could be damaged, and possibly the 5 volt regulator U5.

These parts are logic components and do not do well when subjected to an
overvoltage condition.

If you want to do the best repair, I suggest simply replacing all those
components (except the encoder until it is proven faulty - encoder is an
expensive part). Replacing all of the suspect components is likely
easier than attempting to debug the digital signals to determine which
ones are possibly damaged. Even if some of those components work now,
their life is surely shortened, and may fail later. The parts cost is
not excessive, and I recommend replacing them all.

So I purchased a NUE-PSK modem kit ( I had them do the surface-mount

I also ordered the cable that connects the modem to my K2, but I was
informed that the cable would be shipped separately. After waiting
for nearly a month without receiving the cable, I decided to make my
own. I followed the generic cable-wiring diagram that NUE-PSK
provided in the kit assembly manual.

My crash-scene investigation revealed that I had pumped 13.5 volts
from the modem into the K2's microphone jack, pin 6, which is marked
on the K2 schematic as a 5 volt line.

Now, when I push the K2's POWER ON button, I hear an initial relay
click, but that's it!!!
No LCD display, no bar graph, no audio, no band or mode change occurs.

I'm hoping that I only fried the 5 volt regulator, U5, on the Control

It's been a great low-power rig for more than 4 years, and I'd sure

Re: [Elecraft] K2 - Battery needs CPR

Sorry, but there is no good cure for your exhausted SLA battery.  They 
do have a limited lifetime, but if left discharged for a significant 
length of time, there is no bringing them back.  I would guess that your

yet know how to do them if they are.

On my K2 I could use my paddle as a PTT when operating SSB using a 
headset.  That was handy.  The paddle was right there.

On my Orion, that same feature is a option on a menu and I was always 
sure to enable it.

I wish the K3 could do that , too.

I know I can use VOX or the XMIT key on the keyboard.  Not so handy.  I 
could rig up another key or footswitch too the PTT on the back of the 
K3, but I'd rather just do it the way the K2 does.

I may be alone in this, but feel better that I got to voice my

Re: [Elecraft] K1 - High current drain on power on

Ian,

Check and re-check T4 to be certain the windings are not interchanged.
Secondly, check to see if the High Current condition occurs on all 
bands.  If it is only on one band, the suspect the Low Pass Filter for 
that band.

Check the base DC voltage of Q7 during transmit.  If it is other than 
zero volts, you should look for a solder splash somewhere that is 
causing Q7 to conduct heavily.

These are only starters - there is no one answer to a problem such as 
this - there can be several causes, only to be revealed with further 
measurements.

 This is with just the RF board and front panel connected. Supply is a bench

 On my first attempt to use the rig the Q7 on the finals melted. This has been 
 replaced but it was clearly the poor recipient of the high current and not

 I have carefully checked each component is in the correct place and

 I've checked each solder joint.

Re: [Elecraft] Question on AGC Threshold voltage during Test and Alignment Part I

Fred,

Your problem is not really a problem.  The cause is the 8 volt regulator 
which is on the low side of its 10% tolerance range.  Just set the AGC 
threshold pot to maximum and all will be well.

If you want to optimize the AGC threshold later, you may do that, but 
wait until you have the K2 complete and functioning.

Re: [Elecraft] K3 - CWT ON/OFF change request

2009-01-20 Thread W6NEK

Hi Joe,
Thanks for the observation.  Yes, I now confirm that if I'm operating CW 
with the CWT function turned ON and then switch to another band (which was 
previously left in CW mode) then the CWT will remain ON.  However, if the 
band I switched to is any other mode then CW then the CWT function is turned 
OFF.  So it looks like half the request I asked for is already implemented! 
Now all that is needed is to change the firmware to leave the CWT function 
in whatever state I left it in prior to changing from CW to any other mode.

Re: [Elecraft] K3 feature request - I want Ducking!

That is an interesting idea Keith. I've been reducing the gain by hand
whenever the band noise is objectionable while sending. Been doing that
since I was using a regenerative receiver back in the early 1950's.

But I also grabbed the gain control on the board at KVCR when I was spinning
platters (the real VINYL platters) when I wanted to talk over the music back
in the 50's too. 

So I guess it's a good idea whose time has come, just like people on the
board don't need to play with the gain control any longer. 

But I wonder just how automatic our world is becoming? 

A popular theme in sci fi fiction back in the 50's was that the human race
would so completely automate things that the computers would see to our
physical needs and we'd become disembodied beings floating in an energy
field because we no longer needed bodies to manipulate anything ourselves -
until the computers decided they didn't need us any longer. 

Guess I'm archaic. I still enjoy running on the beach, sketching a scene
with an old pencil and paper, wiggling my own CW key or turning my own gain
controls. 

I'm definitely one of the ones who is now obsolete I guess... But happily
obsolete :-)

[Elecraft] Elecraft K-3 SSB and AM Squelch

2009-01-20 Thread Don Rasmussen

Dave, I emailed K3Support and they say that the AM transmit is 100% Are you 
sure it's not a setup issue? Any more than 10w will be a problem, as well any 
compression on AM, not good, and AM is very Mic Gain and microphone 
sensitive. What say? !!! Firmware version 2.38 (Sept 2008) included compression 
on AM, since then
there has been none. I used to call into the local AM net but it's too
embarrassing now with everyone commenting on how poor the K3 sounds.

73 Dave, G4AON
K3/100 #80

Speaking of AM, how is everyone setting the K3 up for AM now? I used to
have
good luck with it many Firmware updates ago. The last time I tried it,
several upgrades ago, I was not pleased with it on tx.

Re: [Elecraft] KRX3: configuration for second antenna routing

Brian Machesney wrote:

 I have the TMP cable connected between the KAT3 and the KRX3 input. 
 The TMP cable from the Aux RF BNC connector is present but insulated, 
 per the manual instructions, so it is inactive.

 I want the input to the KRX3 to come from the ANT2 connector. What I 
 need to know is how to set the configuration options to make this 
 happen. Obviously, the KAT3 and KRX3 CONFIG menu options are set to 
 something other than notInst. The only options for the KRX3 are 
 Ant-Atu and Ant=bnc. So, if I have the KRX3 set to Ant=bnc and 
 the KRX3 input coming from the KAT3, I would expect the KRX3 input to 
 come from the ANT2 connector - but it doesn't; it still comes from the 
 ANT1 connector.

Hi Brian,

You have the menu entry correct; you need only select AUX for the sub 
antenna. You can do that two ways: (1) in BSET mode, tap ANT; (2) 
outside of BSET mode, *hold* RX ANT. The setting is saved per-band, and 
separately for diversity (AUX) vs. non-diversity (MAIN) on each band.

Re: [Elecraft] K3 - CWT ON/OFF change request

This is already on the list -- now moved up a notch.

 I would like to request that the operation of the CWT function be

 Now when ever I am on CW and enable CWT as soon as I change modes, or 
 switch
 bands, the CWT function is turned OFF.  I would like to see the CWT 
 function
 remain ON until I turn it OFF.  This function can either be global or 
 on a
 per-band basis.  Right now it's a real pain to have to re-enable CWT
 everytime I switch modes, or bands, and return to CW mode.

 I know the firmware change request list is very long but I hope this 
 can be
 implemented sooner rather then later.

 Many thanks to the Owners/Designers of Elecraft for encouraging it's
 customers to make suggestions and actually implement a significant 
 number of
 change requests.  Elecraft is truly unique in this regard.  Thank you!

Re: [Elecraft] K3 feature request - I want Ducking!

Ron,

I too am a firm believer in the KISS principle.
Too much automation drives me crazy trying to remember what the 
automation is trying to do for me.  Oft times the automation does not do 
what I want to be done.  manual controls forever.

This is not a vote against automation and ease of use, but there are 
times when it is more effective to bypass the automatic controls, engage 
the brain, and get what one wants accomplished.  Automation cannot 
substitute for individual preferences - that takes 'brain power' - so THINK!

 That is an interesting idea Keith. I've been reducing the gain by hand
 whenever the band noise is objectionable while sending. Been doing that
 since I was using a regenerative receiver back in the early 1950's.

 But I also grabbed the gain control on the board at KVCR when I was spinning
 platters (the real VINYL platters) when I wanted to talk over the music back
 in the 50's too. 

 So I guess it's a good idea whose time has come, just like people on the
 board don't need to play with the gain control any longer. 

 But I wonder just how automatic our world is becoming? 

 A popular theme in sci fi fiction back in the 50's was that the human race
 would so completely automate things that the computers would see to our
 physical needs and we'd become disembodied beings floating in an energy
 field because we no longer needed bodies to manipulate anything ourselves -
 until the computers decided they didn't need us any longer. 

 Guess I'm archaic. I still enjoy running on the beach, sketching a scene
 with an old pencil and paper, wiggling my own CW key or turning my own gain
 controls. 

 I'm definitely one of the ones who is now obsolete I guess... But happily
 obsolete :-)

 -Original Message-


 No, the manual way to achieve this effect is to turn down the AF gain
 while you're transmitting.  Sidetone is still there nice  loud but the
 RX audio that you hear between elements is reduced.  When you're done
 sending, you reach for the AF gain and turn it back up to the normal
 listening level.

 Now, imagine it was automatic.  As soon as you send, the K3 turns AF
 gain down and leaves it down until a second or so after you finish
 sending, then it turns it back up to where it was.  This way, while
 you're sending, the AF signal that you hear between dots  dashes is
 quieter than when you're just listening.

 Is that any clearer?  If not, ask more questions :-)

[Elecraft] Elecraft K-3 audio controls

2009-01-20 Thread Milt, N5IA

All,

I am wanting to change the audio gain controls for the main RX and the sub RX 
so that they perform in the common audio gain and balance control configuration.

I am unable to find the directions to affect this change.  Can someone indicate 
the location of the instructions in the manual.

Thanks in advance for your time and effort.

In the CONFIG menu change SUB AF to BALANCE.
