Re: [Elecraft] P3 Phase noise/HighSignal Response?

[Jim Brown]

Hi Dave,

The P3 is quite good for measurements, and the SVGA card is even 
better.  Here's a collection of work I've done with whatever rigs and 
amps I could get my hands on to measure.


http://k9yc.com/P3_Spectrum_Measurements.pdf

In my experience, if you keep the K3 within its linear region, you'll 
get good data from the P3 if you understand the measurements you're 
making.  Limitations -- the dynamic range is 100 dB, but you can only 
display 80 dB on screen. For all of the operation I do, I use the P3 
with a lot of averaging and a slow waterfall, fairly large waterfall.  
For measurements, I use the P3 in Peak reading mode and let it 
accumulate peaks for a while. I make the amplitude display pretty large, 
set it for 80 dB, and adjust levels to fill the amplitude screen.


When I'm checking CW bandwidth, I send a series of dits in the range of 
35 WPM for at least 20 seconds I reset the peak a second or so after 
I've started sending dits so I don't see any initial transient that 
might be present. Notice that I set the span for a fairly narrow bandwidth.


The annotations you see for bandwidth are obtained by moving the cursor 
to each data point and writing down the readings, and they are the 
DIFFERENCE between the high and low points.


If you want to show data more than 80 dB below the peak of the signal, 
you can repeat the measurement with the reference level reduced by 20 
dB.  More than that and the P3 will overload.

Re: [Elecraft] Setting Mic Gain to ALC Problem Solution

[Bert via Elecraft]

A week or so ago I posted a problem I was experiencing with my K3;  in SSB 
mode, I couldn't "crank down" on Mic gain to get the last ALC bar to  
flicker. I had either seven bars (Mic setting 3 or above) or none! The bars 
were  
solid...no flicker anywhere. On-the-air checks detected nothing wrong with 
my  audio or signal...but I had 7 solid ALC bars! I was using a CM-500, 
plugged into  the rear panel (rP.H bIAS selected).
 
 
Elecraft support  suggested that to set Mic gain properly  that I first set 
CMP to zero, reset TX Eq settings, then set the Mic gain. I  tried that and 
still had the failure.

I tried several other things: latest firmware upgrade,  re-installing a 
known "good" configuration file, trying another mike (older  lightweight Heil 
with DX element), reseated the KIO3 boards several times to  assure a good 
contact, and even a borrowed mike that I plugged into the front  panel (FP.H 
bIAS selected) -- all produced the same results, seven solid ALC  bars or 
none! 
 
Support re-iterated that I try re-loading a known good  configuration file. 
I did that again and it
still failed. Then I thought back to his suggestion about setting  the Mic 
gain properly; this time, instead of resetting the settings manually as  I'd 
done before, I hit the CLR button instead, and the settings were reset. 
THAT  WORKED! I was now able to adjust the setting so I would get the last bar 
to  flicker. I could also see, if I was careful enough, the ALC reading 
increase  from zero to seven bars, something it wouldn't do before. 
 
I've increased CMP back to the way I liked it but haven't played  with the 
TX Eq yet...gun shy!
 
I thought I'd pass this along, right or wrong, just in case it  helps 
somebody in the future.
 
73, Bert N4CW

[Elecraft] P3 Phase noise/HighSignal Response?

[K5MWR via Elecraft]

I am trying to use my P3 to evaluate signals from other hams here in my 
community.  While I know the K3s is excellent, I am not sure what to 
expect out of the P3 in terms of phase noise or response under high 
signal conditions.  I can always pad to lower the signal but that will

Any experiences?

[Elecraft] Crosspost: K3S FSK shifts RX freq after Xmit

[Chuck Chandler]

Cross-posted to both DXLabs and Elecraft lists, since I am not sure where
the issue lies.

After some experimenting, I find that my K3S will shift the receive
frequency after transmitting in RTTY (FSK D Data mode.)  Finding a busy
band, I can see that if I tune in 5U5R exactly on 14.080.000, then send a
RTTY transmission that after the RTTY transmission ends my rig is now still
showing 14.080.000 on the screen but I am receiving a signal from somewhere
around 14.078.78, near as I can make out from the P3.  There's another data
mode being used down there and the fellow has a nice, strong signal that
comes and goes so I can tell when the signal starts and stops. This happens
when I send from the keyboard as well as from a macro.

I first noticed this in live transmissions but have spent the last half
hour in TX Test mode, and the same thing happens even with no output.

As soon as I tap XFIL the filter setting doesn't change but there the 5U5R
is again.

Alternatively, if I rotate the Shift knob either direction, the 5U5R is
back.  The FC is set to 2.21 kHz.

Alternatively, if I rotate the width control in either direction, it goes
back to receiving the 5U5R.

This only happens when I am using the 400 Hz 8-pole filter or the APF
(which also uses the 400.)  When I use the 2.7 5-pole this doesn't happen.

This feels like something is applying an offset of 1220 Hz while I transmit
and not letting it go.  But I'm at a loss to figure it out.  My digi app is
WinWarbler, and I have AFC unchecked.  It shows a steady freq for xmit and
rcv at 14.080.000 during all this.

1220 is just about half of 2210, so there's that.  Also, the K3S TX Test
mode doesn't key the finals, so there's no RF getting into it.

This feels like something is set wrong, but blimey if I can figure it out.

Re: [Elecraft] K3 and PSK 31

[Don Wilhelm]

Andy,

I did not see any response on the reflector, so I will try.

First of all, you need a soundcard.  If you have installed the KIO3B in 
that K3, there is an internal soundcard in the K3 that can e used.
If the KIO3 has not been upgraded, you will need a soundcard external to 
the K3.  Either an internal computer soundcard or an external one.
The computer must send audio to the K3 Line input and receive audio from 
the Line Out of the K3.


HRD (or Win4K3 or other applications) will provide rig control functions 
without the audio paths.


For instance, PSK31 (and other data modes) sends audio tones to the K3 
via the computer soundcard, and receives audio tones from the K3 for 
decoding.


Set the K3 to DATA A submode (AFSK A for RTTY), and during receive, 
adjust the computer Line In (or Mic) level to give you a good waterfall 
display.  You can also adjust the LINE OUT level in the K3 menu.
For transmit, adjust the soundcard Line Out (or Speaker) slider to about 
75% of full and then in the K3, set the MIC SEL menu to LINE and adjust 
the "MIC GAIN" (actually LINE IN gain) so you have 4 bars illuminated 
solid on the K3 ALC display with the 5th bar flashing.

Adjust the desired power level with the K3 power knob.

Ignore the internet advice (and some software applications) to set the 
power to max and adjust the power output with the audio level - that 
does not work well with Elecraft gear.  That advice is for other 
transceivers which do not control the power output by actually measuring 
the power level and making adjustments to make the power equal to the 
requested power level.  Use the instructions in the K3 manual - 
paraphrased above.

Don W3FPR

For DXpeditions and most contests, using the K3/K3S memories will send the
RTTY at normal 60 WPM speed.  There is no reason to send CW and have the
RTTY come out at a slow speed which is rude to the other operator.  All you
need is two memories programmed, one with your call sign and the other with
your exchange.

[Elecraft] Subject: PR6-10 vs KXV3B

[Edward R Cole]

I'm using the PR6-10 on my K3 (SN4043) and it helps 10m and 6m Rx, 
immensely.  I also have a ARR 6m gasfet preamp mounted on the 6m 
tower for eme and use DIGIOUT-1 to select either preamp with the ARR 
on the bypass connector of the PR6-10.


What I got from reading of the original problem was that there was 
insufficient gain in the K3 Rx chain at high-end frequencies to 
provide adequate sensitivity, so the preamp mainly adds gain to the 
chain.  Fact that the NF is a little lower does not hurt if you are 
in a low noise environ.


On 6m-eme local band noise floor is the prime limit on MDS, other 
than needing more antenna gain (single yagi 13-dBi).  15 dBi is 
considered the minimum for realistic eme reception.  That seems to be 
my circumstance where other stations see my 1000w long before I see 
them (I have to use ground-gain enhancement to see eme).

Re: [Elecraft] KBPF3 mod kit

[Don Wilhelm]

Ted,

On the battery replacement, it is easy, bu consider whether you really 
use the real time clock on the K3 - keeping the clock going during power 
down is its only use.  If you do not use the internal clock, then do not 
bother.


When you have the K3 open, it is an opportune time to replace it, but 
those batteries last a long time in an application when it is only 
keeping the clock chip active (as is the case in the K3).


Compare it to the battery in a computer which does the same function. 
How many times have you had to change the battery in your computer?

Re: [Elecraft] KBPF3 mod kit

[Ron D'Eau Claire]

Hello Dale:

One of the significant mechanical changes to the K3S was a battery holder that 
lets the battery lie flat so it can be replaced without pulling the KRX3 
enclosure. Also, lying flat the battery does not need a protective cover.

Yes, the battery lasts a very long time, like the bios battery in your 
computer. All it does is keep the real-time clock running when power is off. 
The battery is unimportant if you don't use the clock. If you do use it or just 
want to have  good battery in place, why not change it after 5 years if you are 
"under the hood" anyway? You need a CR2032 3-V battery.

I would remove the left side panel (the side panel with the handle) along with 
the top cover, Then loosen the two long screws that hold the KRX3 enclosure in 
place and lift it enough to take the battery cover off and replace the battery. 
Having the side off makes it easier to ensure the interface boards between the 
KRX3 module and the RF board are seated when you replace the KRX3 module. With 
a little care you won't have to disconnect the TMP coaxial cables.

Be sure to replace the battery cover. The positive (rim) of the battery can 
short against the bottom of the KRX3 enclosure if it is left off. 

When you replace the side cover, be sure to replace all SEVEN screws, including 
the one near the forward end of the handle. That screw is easily overlooked but 
is essential for proper shielding.

Re: [Elecraft] [dxlab] WW and K3S FSK RTTY

[Chuck Chandler]

I just worked 5U5R on 17M RTTY and paid attention to what was happening...

I did set the QSO selector to X, and it transmits now when I send.

At first, if I double-clicked in the S pane to capture the callsign, it
would clear the callsign when I then clicked in the X pane.  I *THINK*
setting QSO selector to X allowed me to capture the call in S and still
transmit via X.

However, after unkeying I observed the following:

I could hear what sounded like band noise, and saw some background noise in
WinWarbler, but looking at the P3 panadapter I could see the big signal I
should have been hearing.  Tapping XFIL brought the signal back into my
headphones and onto WinWarblers display.

Also, before doing this I had gone through the K3S config menu to confirm
the right filters were set for DATA receive.  I also made sure that in DATA
the filters were centered at 2.21 kHz.  My offsets are set to 2210 as well
in WW.

Also, tapping the XFIL button, while it should pick the other (of two)
installed filters instead just brings back the audio... it doesn't swap to
the other filter, just to the one I had already selected.

I'm cross-posting to the Elecraft group to see if anyone can tell me what I
might be doing wrong...

Re: [Elecraft] KBPF3 mod kit

[GRANT YOUNGMAN]

I don’t think removing the side panel is necessary for these mods.  But it’s 
been a while.  The sub-receiver is actually pretty easy to pull and reinstall. 
Just follow the instructions that come with the mod kits.  I’ve found the best 
way to “sight” the sub receiver re-install is to first target the connector at 
the rear.  It’s easier to see and line up.  The front connector will fall into 
place.  Biggest issue (exacerbated if you have the 2M xvrtr) is keeping the TMP 
cables out of the way while dropping it in.

Be aware that the KBPF3 mod requires installing 3 0603-sized surface mount 
caps.  These things are literally flea sized and NOT easy to deal with if you 
aren’t familiar with handling them.  Elecraft supplies an extra in case you 
lose one.  Best to use a hot air rework tool IMHO, but can be done with a fine 
tipped (ESD-safe) iron.  Either way, I’d suggest liquid flux (if you don’t have 
any) to make it as clean and easy as possible.

Can’t comment on the battery.  Mine’s been in there since 2007, and seems to be 
hanging on just fine.

[Elecraft] Looking for an KXV3 board

[Jay Radcliffe]

Hello,

I am in the middle of upgrading my K3 with the 2m transverter and
discovered that I have the old KXV3 board that doesn't have the two
TMP ports. The Elecraft support people suggested I ask here to see if
someone has an older KXV3 that has the two TMP ports for sale.  Maybe
from as a leftover from an upgrade to a K3S or newer KXV3B setup.  I
really do not want to spend $200 on the KXV3B when I don't really need
to.

Thanks in advance and 73s

Unless we are trying to enhance goodwill between silicon chips located

actually speaking with humans might actually be part of the basis and

I'm sure others will disagree, and I do understand that this is not how

Re: [Elecraft] RTTY -- (mostly OT)

[GRANT YOUNGMAN]

In many communities you can grow old, wither up, and blow away in the wind 
before finding someone to “maintain community” with on a local repeater (WX 
nets excepted).  I stopped going there years ago .. the final straw was a local 
couple who never seemed to tire of having “repeater sex” in the wee hours of 
the morning on the primary repeater of an (un-named) large city radio club.  
Not that it wasn’t sometimes interesting … 

Different strokes I guess.  There is virtue in HF exchanges that go beyond “599 
TX TU QRZ“ and "advancing the art", which is not to say that the content 
(regardless of mode) is markedly better  :-)

I know this is "old hat" now, especially for serious RTTY buffs 
(which I am
not!), but every time I work one of these DXpeditions on RTTY, just 
using

the K3 and CW input, I get a big kick out of it.  I just did that on 40
meters with TU7C in the Ivory Coast.  I crank out CW at about 25-30 
WPM and

the K3 does the rest!  Cool!  I could do this with my KX3 or KX2 if my
antennas were better!

That's about the only time I venture into the RTTY segment, and I would
generally rather just rag chew on CW, but snagging another DXpedition 
band
slot this way is fun.  It sure beats the heck out of the way I had to 
do it
in the Army eons ago, with those model 21's, or whatever the 
nomenclature
was--I've forgotten now.  That was in an AN/GRC-26 van, with a 
BC-610, an

R390, and a rack panel filled with other stuff.  It sure got hot inside
those vans  With the K3, I can do it all on a TV tray!

Re: [Elecraft] RTTY

[brian]

This works very well.  K4CIA who never operated RTTY before a few years 
ago uses only the K3 display and built-in memories to call and work DX. 
 He has now worked over 300 RTTY countries with the K3 only one finger 
method.  No computer, sound card or RTTY program used. KISS.

Re: [Elecraft] RTTY

[Don Wilhelm]

All,

Also end the message memories with the "|" character so the RF ends 
IMmediately.
If you are entering the message with the paddles use "IM" sent as one 
character (no space).


You can use those same message memories on CW too, the | character is 
ignored.

[Elecraft] PR6-10 vs KXV3B

[Dauer, Edward]

Thanks, Brian.  My experience is consistent with yours.  My operating QTH is in 
a remote area with the nearest neighboring house a twenty-minute walk away.  
The power line to our house comes underground for a little more than the last 
200 feet.  The difference with the PR6-10 on 15 meters is unmistakable.  
Perhaps it is the low-noise environment that makes it effective.

Ted, KN1CBR



On 3/13/17, 7:48 AM, "briancom"  wrote:

Right on.  The new board preamp only works 12 through 6 M.  More gain would 
be helpful on 17 and 15 M.  I hope Elecraft can open up access to  the new 
preamp on those bands-even if it is 6 dB.
My experience (older K3) with an external preamp and decent antennas showed 
that some extra gain on 17 and 15 M helped.  15M is an especially quiet band 
and extra gain was welcome.  Also it helped overcome the 3 dB loss in signal 
when the subrx was sharing the main ant.
Now that I have relocated to another QTH and have much poorer antennas and 
lower sunspot numbers, the extra gain on 15 and 17 would be welcome. Most guys 
are hearing me better than I am hearing them.  More gain on those bands might 
open up new layers of guys to work.
Of course there is the question guys always ask : Why does it do anything 
placed at the RX front end.
The fact of the matter seems to be that even if you just think it helps, it 
is a  benefit.  Measurements made with a signal generator show the new preamp 
does improve the MDS under the condx of no atmospheric noise present.  Some of 
this might indeed show up for quiet bands.

Re: [Elecraft] RTTY

For DXpeditions and most contests, using the K3/K3S memories will send the
RTTY at normal 60 WPM speed.  There is no reason to send CW and have the
RTTY come out at a slow speed which is rude to the other operator.  All you
need is two memories programmed, one with your call sign and the other with
your exchange.

Re: [Elecraft] VOX/PTT select macro ?

[Jim Brown]

I've never used PTT, either by hand or with a foot switch in my station. 
The only time I've used a foot switch was at a multi-op in a SSB 
contest. VOX works very well for me for all modes, and I'm too poorly 
coordinated to use a foot switch -- it keeps moving away from my foot. :)

Hi Linas,

I can't duplicate this problem on my KX2. I would suggest re-doing the transmit

Set mic gain to about 15-20 with the MH3, or about 30-50 with the internal mic.

[Elecraft] KX2 80m LSB bug

[Irma Linas]

Hello group,

I am now a proud owner of the brand new KX2 which arrived few days ago
straight from CA. Being also a proud owner of an old and fully upgraded K3
I found this little rig very familliar to operate and navigate. Very lovely
package of all what you need on QRP, including the battery pack and the key
paddle! I am especially amased by the built-in microfone - it works very
nicely and I am re-descovering the SSB mode being mainly the CW op! The RX
audio quality  of SSB signals is outstandingly pleasant even with this
small speaker! The general sensitivity of the receiver though  seems a bit
too low compare to the K3 thus the preamp is needed most of time even with
good antennas. But that is no problem.

A strange bug appears to live in the radio. It only related to 80m band LSB
mode. It is not possible to get the signal transmitted if you are on 80m on
power-up or if you come to 80m LSB from another band. Pushing Xmit or mics
PTT puts the rig into transmit mode but RF meter shows no output. If you
want to transmit, you have to change the mode into CW, transmit a dot or so
( it always works on CW ok ) then change back to the LSB mode and then only
it starts transmitting your SSB signal out. The bug is NOT related with the
" RF in the shack" case, it is there with different antennas and the dummy.
The bug is permanently there and does not depend on battery supply,
voltage, etc. I have also tried to reload the latest firmware , no change.
So I think it could be the firmware problem.

Would be interesting to know if anybody else experiencing the same strange
effect?

72! de Linas LY2H
KX2 #1488
K3 #1568 S-upgraded

Re: [Elecraft] K3 upgrade to K3S question

[briancom]

Right on.  The new board preamp only works 12 through 6 M.  More gain would be 
helpful on 17 and 15 M.  I hope Elecraft can open up access to  the new preamp 
on those bands-even if it is 6 dB.
My experience (older K3) with an external preamp and decent antennas showed 
that some extra gain on 17 and 15 M helped.  15M is an especially quiet band 
and extra gain was welcome.  Also it helped overcome the 3 dB loss in signal 
when the subrx was sharing the main ant.
Now that I have relocated to another QTH and have much poorer antennas and 
lower sunspot numbers, the extra gain on 15 and 17 would be welcome. Most guys 
are hearing me better than I am hearing them.  More gain on those bands might 
open up new layers of guys to work.
Of course there is the question guys always ask : Why does it do anything 
placed at the RX front end.
The fact of the matter seems to be that even if you just think it helps, it is 
a  benefit.  Measurements made with a signal generator show the new preamp does 
improve the MDS under the condx of no atmospheric noise present.  Some of this 
might indeed show up for quiet bands.

[Elecraft] K3 upgrade to K3S question

[Dauer, Edward]

A question about the KXV3B –

I have done the synth upgrades but none of the others, yet.  I am considering 
doing the KXV3B and the KIO3B.  

At present I have a PR6-10 hanging off the back of the K3.  I have found it 
very helpful on 10 meters and on 15 and maybe a bit on 20.  I have not done any 
laboratory-grade measurements, but a simple on-off on 15 is convincing that the 
preamp is of use there, and 20 is maybe or maybe not.  

The KXV3B Manual is clear that band selection should be done on 12, 10, and 6.  
I would be disinclined to doing the upgrade if I lost the preamp advantage I 
now have on 15.  Does anyone know if the preamp in the KXV3B is identical to 
the outboard PR6-10 and, if so, whether the K3 with an new KXV3B will accept 
the preamp ON designation for bands other than 12-10-6?

Thanks,

Ted, KN1CBR

The KIO3B has both RS232 and USB.

All 3 upgrades are easy to do together.? Now takes me less than 30 minutes 
total for 2 KSYN3As, KXV3A and KIO3B.

Hi.

This sounds more like the USB<>KX3 cable driver firing up as a Serial
port that the updater was not defaulting to.That can happen if there
is something else already connected to the computer that provides a
"Serial" port for some other reason, before you plug in the KX3 cable.

I've never seen the KX3 utility run on an Apple box, but on Windows and
Linux, you get a chance to find and specify the serial port to use.

(Also just recently updated a KX3 to the latest releases with no issues,
using Linux Lite on an Acer One Netbook.)
