[Elecraft] MD2 microphone

[Stephen Prior]

I don't know whether anyone can help, but I am trying without any success
to get the MD2 microphone working with a SunSdr2 transceiver, which is able
to provide the necessary bias voltage I believe.  What I am lacking, and
have not been able to find online is the original manual for the microphone
giving pinout and bias details - for I'm sure that there is something that
I must have missed.

Thanks and 73,

Stephen G4SJP

[Elecraft] Interfacing SunSDR2 pro to KPA500/KAT500

[Stephen Prior]

I would be interested to know if anyone has got their head around using the
SunSDR's DB15 accessory connector to switch and provide band information to
the KPA500?  I have tried but I've had no success!

I know that I can use the RF sensing capability of the KPA500, as that's
how I have it set up at the moment, but I am looking for a more elegant
solution.

Thanks and 73

[Elecraft] Using SunSDR2 pro with KPA500

[Stephen Prior]

Does anyone have any experience of fully interfacing this SDR with the
KPA500 please?  I confess to be rather confused.  I am looking to configure
the Ext Ctrl tables with the BCD values that the KPA500 requires for band
switching etc.  I understand what BCD is, but in this context I'm confused
as to how to define it in the SDR's setup.

Thanks and 73

Re: [Elecraft] Mac Clock Question

My 2012 Mac mini running 10.13.3 keeps within a few tens of milliseconds

[Elecraft] Looking for a small VGA monitor for the P3 available in UK

[Stephen Prior]

I have recently rearranged my operating position and have lost the space
where my old Sony 15 inch monitor used to act as an external display for
the P3.  Has anyone bought (and are happy with) a much smaller VGA 1024x768
monitor, say 7 or 8 inches in size? There are plenty on amazon.co.uk but I
am suspicious as to their quality and also their immunity to nearby RF
fields.

Suggestions welcome, but looking to resource this from UK based stock and
only models that have actually been tried out and found to be okay.

Thanks and 73,

Stephen G4SJP

[Elecraft] [KX2] Cannot turn off switch cw tones

[Stephen Prior]

I was playing with the new features in 2.81 and enabled the tones by
holding down APF (plus Rate and A/B) at start-up.  All works great, the
double tap on PTT gives the freq. etc.  However, having established that it
works, I'm now stuck in the mode.  I can go into Setup and turn SW tones to
off but when I turn the KX2 off and then on again, the SW tones is now set
back to 20!

I have read everything I can find, but I cannot see how to get out of this
so that I have no tones of any description.

Any advice gratefully received!

Re: [Elecraft] LiIon types, and safety (was: Fire in the house li-ion)

[Stephen Prior]

Which is why I've given up on homebrewing an extra pack - albeit for
external use - I have bought another KXBT2!

I have to say though, that I'm still not finding it totally straightforward
getting the two halves of the KX2 back together again after replacing the
battery.  When I received the KX2, the battery wires were pinched between
the case and the edge of the vertical filter board and were already showing
chafing of the insulation.  Having removed and reinstalled the filter board
in installing the ATU, I now no longer have the speaker cables pinched, but
I have to be very careful how I dress the speaker cables before putting the
two halves of the case back together.  I wonder if there could be some
further guidance from Elecraft on this?

On a different topic, having now bought the option which includes the clock
module, I'm looking forward to the firmware update which will provide us
with the logbook data based upon transmitted CW text!  Thanks in
anticipation Wayne!

[Elecraft] Replacing the bulky IEC cable in UK used KX2's

[Stephen Prior]

If like me you are rather horrified to find that the Li-ion charger and
cable for the KX2 takes up more space in a bag than the transceiver itself,
I've just found one of these adapters which replaces the cable completely.
No doubt similar adapters exist for other mains plug designs.

[Elecraft] KX2 front panel lettering disappearing

[Stephen Prior]

Before I take this up with the UK agent for Elecraft, I am curious as to
whether anyone else has experienced the yellow lettering rubbing off,
particularly at the bottom of the front panel?  I have only had my KX2 for
a couple of weeks and just had my first QSOs with it yesterday, so it's not
had any prolonged treatment.  It looks to me as if the lettering at the top
of the panel is fine.  White lettering seems much more robust.

Re: [Elecraft] KX2: mini-banana plug

[Stephen Prior]

Further to my previous message, thanks to Ben W4SC,  I have identified the
plug I need.

For UK readers, put Pomona 2945-0 into your favourite auction site and you
will find several at decent prices.

[Elecraft] KX2: mini-banana plug

[Stephen Prior]

Had my KX2 some days now and very pleased with it.  I thought I would buy
some mini-banana plugs for the counterpoise, but they are too small to
properly fix in the hole provided.  I had assumed that the KX2GNDPLUG would
be a standard size.  Postage from USA makes for a very expensive little
item.

The mini-banana plugs as available from the likes of Amazon are 2mm
diameter.  I can only assume that the KX2GNDPLUG is bigger?

Thanks for any comments,

73, Stephen G4SJP  (KX2 #1200).

Re: [Elecraft] K3 for SWL?

If I were looking for something like that I'd be thinking about the Elad

Re: [Elecraft] KX2 display on start-up

Hi Gary

I had a reply from Wayne, it's quite normal apparently, almost a

[Elecraft] KX2 display on start-up

[Stephen Prior]

Just received my KX2 and I'm very pleased with it, although fitting the ATU
was a challenge, even after having read the updated information on it!

Anyway, I believe all is well but there is something that I don't
understand.  If the KX2 has been off for a while, when I turn it on I get
some random parts of characters, mainly along the bottom half of the
display.  They remain there for about 3 seconds until the display
illumination comes on and the rest of the display disappears.  This is
absolutely no big deal unless it's a sign of some issue somewhere that has
yet to rear its ugly head!

Running latest (2.69) firmware.  I have a K3 and KX3 and have never noticed
this behaviour with them.

Re: [Elecraft] Using KX3 with Android device...

[Stephen Prior]

I'm afraid that I have to agree with Mark.  When I first saw KX3 companion
on a friend's tablet, I was very taken by it, so much so that I bought a
Lenovo tablet in order to be able to use it.  However, the first portable
operation found me simply not wanting to be bothered by the extra layer of
things to set up in the field (mid thirties celsius didn't help here) and
instead just controlled the KX3 from its front panel.  Maybe I should take
another look at it,  it's a fine piece of software.

Re: [Elecraft] APF (audio peaking filter) on the K3/K3S/KX3

[Stephen Prior]

I've seen it written that it helps to offset the IF slightly, although to
be honest I have never myself got the APF to work to my satisfaction.
Oddly, and I communicated with Wayne about this at the time, the first beta
(I think) implementation of it was stunning, but a later release lost it
for me.  Wayne told me there had been no change in code, but I have never
understood that.  With my XYL away in London for the weekend, I might
devote some more time to it :-)

[Elecraft] P3 TXMON sensor CAL value

[Stephen Prior]

Hi,

Having installed the TX monitor and 2kW HF/6m sensor this evening, I am
curious as to how many have found it necessary to make significant
adjustment to the sensor calibration value in the P3 menu.  I have no
accurate means here this evening of measuring power, but the output from
the KPA500 at an indicated 500W key down on the amp shows as only around
350W on the P3.  I have the sensor between the KPA500 and KAT500, so the
sensor is seeing a good VSWR.

Just curious, as I know I need to make more accurate readings, but I'm
wondering what others have found.  I have adjusted the CAL up to 550 from
its 500 default value, which seems to make things about right.

I would never expect close agreement in power measurement as I know how
hard that is to do, I spent a long time early in my (first! )career making
and adjusting directional couplers for military applications, so I know the
constraints!

Re: [Elecraft] P3TXMON question?

[Stephen Prior]

Bill,

That's absolutely right.  There's so much confusion about such things and
you have explained it very well.  RMS can only ever be used as a value of
current or voltage, never power.

 It's important to remember that RF power expressed in watts is always
 based on RMS values.  If RF watts are calculated by measuring the voltage
 across a known load, the voltage must be expressed as an RMS value to
 correctly calculate the power in watts.  Watts are watts.  There is no such
 thing as peak to peak or RMS watts when expressing RF power in watts.

 Peak envelope power (PEP) has nothing to do with the difference between
 the peak and average voltage of a sine wave.  It is the measure of the
 power of an RF signal at the modulation peak, averaged over one RF cycle.
 The power measurement within that one RF cycle is still based on RMS values.

Re: [Elecraft] P3 - still in trouble with new firmware

I reported at the time (January I think) that the SVGA NB status wasn't
being saved.  That appears to be still the case here.

 there has been no production release since then except for this new beta

 Will add my name to list about no NB on SVGA.  I didn't know that was
 supposed to be working. Additionally bringing up the NB Level menu entry
 blue screens the SVGA display and shows Tx/Rx Data Font: 0 in the upper
 left hand corner.

 My ancient data processing bug instincts scream mismatched data position
 definitions, but that that's just from an old systems design crank :)

 Did the firmware files get back leveled or something?  This really looks
 like something that would have been fixed in house before public release.

   In addition to the issues reported here, the noise blanker no longer
 works on the SVGA, and the per band settings of the noise blanker are not
 updated on the SVGA display as you change bands.
   I guess there should be another iteration?

   Have you loaded the new SVGA firmware 1.24?  You need this as well as

 Try performing a parameter reset (MENU+PWR) and see if that fixes the

 write them down beforehand.  Almost all SVGA parameters are saved within
 the

[Elecraft] P3 - still in trouble with new firmware

I wrote too soon,

Having uploaded all firmware to the P3 rather than just the new files, I am
still seeing problems - in particular with the sizing of the SVGA waterfall
not being remembered.  Also I have a grey background and lose the fill
under the spectrum line.  Toggling the display button on the P3 restores
the colour and fill but not the waterfall height.

Perhaps I should download all the files from the ftp server again?

[Elecraft] New P3 firmware - don't just 'send new'

[Stephen Prior]

If like me you have just upgraded to the latest version 1.50 beta and you
find that the SVGA behaves rather strangely, not remembering settings on
powering off etc., then you might have just sent 'all _new_ firmware' to
the P3 as opposed to sending 'all'.

Don't ask me how I know...

Don is right.  I thought I had done the right thing some years ago,

Elecraft, not stupidly expensive although the shipping always bites it

 If the RF gain pot is worn it will behave that way.
 If this is a fairly new K2  I would say SN above 4000, the pot should
 not be worn out yet unless the operator used it excessively - so in that
 case, look for an unsoldered connection between the RF gain control and
 the path to the K2 Control Board.

 It offers many functions for rig control and what it doesn't have pre-set

 The macro buttons is where I keep EQ stettings, Mic selections. control of

Never ever had a problem with powerpoles, including their use in a Land
Rover.  Just make sure you hear the click as the pin goes into the
housing.  Tried crimping, went back to soldering...

 But the Phase of a single device/measurement is kind of a meaningless

 So perhaps the proper terminology is dependent upon context. At least that

Re: [Elecraft] K3 Beta 5r10 and LINK

[Stephen Prior]

To my simple minded (physics) view of things, polarity is to do with the
direction in which the loudspeaker cone moves for a given direction of
audio frequency current (Fleming's left hand rule etc.).  So if two
speakers have the same polarity then they will both move forwards or
backwards at the same time, irrespective of the frequency (assuming they
are being fed with the same signal of course!).  Phase differences can only
have any meaning for a given frequency and can have maximum values of +/-
180 deg, +/- pi rads etc.

It is easy to see how the confusion can exist.  Interestingly, an old pair
of AR speakers I own have a 'polarity' switch.

 I understand the word polarity and I understand the word phase after 40

 From Wikipedia: *Phase difference* is the difference, expressed in

Re: [Elecraft] SVGA NB doesn't always start latest beta f/ware

[Stephen Prior]

Hi Jim,

I can't have explained myself very well.  The NB is working (level 10) on
the P3 but on the VGA output the NB on state is not remembered on switch
off.  So if I turn the P3 off and then on again,  the NB works fine on the
P3's own display,  but to make it work on the external monitor I have to
turn the NB off then on again.  Reference to NB here is solely the P3.

Hope that makes sense.  I have been using the NB on the P3's screen for
some time now, but it is only the latest beta I think that extends this
functionality to the P3's VGA output, and that is the version I'm running.

 There are two menu functions associated with the P3 NB. One is the switch,
 the other is NB Level (or whatever it is called). If you're going to use
 the P3 NB, you need both on soft keys. First turn the NB on, then select NB
 Level and tweak it for best noise removal.

[Elecraft] SVGA NB doesn't always start latest beta f/ware

[Stephen Prior]

Using the just-released beta firmware I am finding that on switch on,
although the P3's NB is engaged the SVGA screen still shows pulses (in this
case from an electric fence).  Turning the NB off and then on via the P3's
menu restores functionality.  This is the case on every band I have tried.
No big deal, but sounds like a little bug to me.

Re: [Elecraft] K3 cleanest signal possible

[Stephen Prior]

If the K3 were supplied with a stock microphone, rather than leaving it to
the purchaser to potentially make a poor choice and then not bother to
compensate with the equaliser, I believe we wouldn't be reading these
admittedly  isolated comments about K3s with thin audio.  This has
recently come up again with the current dxpedition in Iran.

I probably make fewer than a dozen SSB QSOs in a year, yet when I do I am
almost always complimented on the audio.  I am using the MH2 microphone.

Re: [Elecraft] K3 KPA500 power on 24/7

Jack,

I suspect that it really doesn't matter too much - components these days
are far less susceptible to turn-on shock.

Were the electrical energy free, I would probably leave it all on.  And all
the lights, heating etc, but that's a different matter as we all know :-)

Now, according to something I've read today on the BBC website, if your
guys over at the skunkworks at Lockheed-Martin can pull off their fusion
reactor as they hope, we _shall_ be able to leave it all on without regard
to cost/global warming etc!  I wish them luck with that!  Looks very
interesting.

 Subject: [Elecraft] KX3 Battery Supply Inoperative 42 Percent of the
 Time...

 OK, Here's the thing...

 My KX3 battery has operated flawlessly ever since I first built the KX3 and
 put in the battery holder/charger feature.  One set of batteries being used
 in portable QRP ops being discharged and recharged many times.  Then, I
 decided to buy the 2-meter module option and install that.

 I started the installation which included taking out all 8 batteries,
 unplugging the battery connector that goes to the other half of the KX3 and
 so on.  I get part way into the installation and discover that I cannot
 finish the job because inductor L40 which has to move cannot physically
 move
 at all.  So, I send it to Elecraft, they do the installation, they send the
 unit back to me and everything is hunky-dory except for the battery
 facility.

 These are the symptoms.  Brand new batteries installed, and I operate the
 KX3 with external power and make sure that the batteries are fully charged.
 The VFO B Display shows BT voltage with a good charged level.  I turn the
 KX3 off, disconnect external power, and go to turn on with battery power.
 Nothing happens, just as if no batteries installed.

 I replug external power, turn on KX3 using external power and check out the
 various battery menu settings and so on.  This time, without unplugging
 external power connector, I merely turn off the external power supply and
 the KX3 continues operating nicely with battery power.  I do a number of
 tests with CW key down into metered dummy load to check TX and a few other
 things.  I think the problem solved.  I run on batteries all afternoon to
 run them down.  Turning on external power I recharge the batteries back up
 to an operating level.  I turn off KX3, disconnect external power, and turn
 on KX3 and nothing happens just like before.  I fiddle with things a bit.
 I
 attempt to do what I did before that brought life back to the battery
 feature but nothing happens.

 I split open the KX3 and check the power plug.  I push in on it a little
 bit.  I put the two halves loosely back together and then do a power on and
 the KX3 comes alive on batteries.

 I am thinking that I have a loose connection somewhere, maybe the battery
 hookup plug that goes across to the other half.

 Anyone have problems with these connectors?  I am wondering if I just give
 up on the battery thing and use my external Li -ion external batteries from
 now on.

Re: [Elecraft] [KX3] S Meter ABS mode

[Stephen Prior]

I would second that Geoff, I have mentioned it more than once on this list
as I think the ABS mode to be so sensible and useful on the K3 - who wants
an S meter which is only accurate some of the time, and by the very nature
of preamp and attenuator settings will, as a consequence inevitably vary
from band to band?   Maybe it's more difficult to implement on the KX3, but
I find it a little odd that it's not yet got to the top of the list.

 microvolts at the antenna doesn’t show as S9 on the odd occasions when I
 use
 the 10 or 30db preamps. Perhaps it’s on Wayne’s list - near the top I would

 It’s a feature that’s a great help in giving consistent and meaningful

Re: [Elecraft] SWR Readings:Differences

[Stephen Prior]

Wes,

As someone involved in the design and manufacture of couplers for VSWR
measurement for the aviation industry (admittedly some 30 odd years ago!),
I would say that you are 100% correct, although I suspect that in amateur
gear number 4 in your list is probably the biggest culprit of all.  We had
people on the production tweaking bridges to maximise directivity and it
was a job that required some skill, e.g. bending leads of matched zero bias
Schottky diodes until the spec was achieved - admittedly this was in the
days before the large scale adoption of lead-less components, which must
have made things a bit easier.

 If I take a lossless 50-ohm line and terminate it in 100 ohm and measure
 the VSWR using an ideal bridge/coupler/VNA/etc that is calibrated for a
 50-ohm system, I will measure 2:1 SWR no matter how long the line is, from
 zero to infinity.  The transformed Z will change with length, but the SWR
 will not.  That's why one can draw a circle of constant SWR on a Smith
 Chart.  Any point on the circle will have a different Z from another, but
 they all have the same SWR.

 If you change line length and the SWR reading changes, then: 1) the line
 has loss, 2) the line Z and the SWR meter Z are different, 3) the source
 match is poor, 4) the bridge/coupler directivity is poor, or 5) all of the
 foregoing.  With most ham stuff, it's 5.

 wave, electrically (that is to say, accounting for the velocity factor)

 Any other length will result in a transformed impedance, and corresponding
 different VSWR.

 You can demonstrate this by changing the feedline length and watching the
 VSWR change.  Try adding some small fraction of a electrical wavelength of
 coax at 40M and see what your meter shows.  You might be surprised.

 TLDR; try adjusting the length of your coax and see if the readings
 change.

Re: [Elecraft] iMic with iSDR on iPad4

I get the same message on my iPad 2 but it will still work - I just ignore

it's just Apple whinging about not buying their bit of kit!  YMMV of

Re: [Elecraft] I got big heavy knobs...

There was an issue mentioned by Elecraft (Eric I think), that they had seen
some failures of the encoders fitted with heavy knobs when the K3 had been

the knob can produce a damaging cantilever effect, much as is the case with
a front loading washing machine!

Re: [Elecraft] Side Effects of QRQ On The K3

[Stephen Prior]

I just tried sending a string of V's at 30 wpm.  Normally my maximum
comfortable sending level is between 20 and 25wpm, so this is certainly out
of my comfort zone.  I am using a Begali Expedition and iambic mode B.
 With QRQ off I was about 75% accurate in my sending of strings of V's,
with QRQ on, it was nearer 90%.  I'm just listening to the sidetone.  That
was with the delay set to zero.

With the delay at 0.06 I cannot see any difference between accuracy of
sending with QRQ on or off, again at the 30wpm level.

I must concur with previous comments that I have found the K3 to be a
wonderful rig to use on CW, but I'm no racer, and never will be!

  You said the odds that you'd ever encounter and notice its effects are
 vanishingly small unless you are a 60+ WPM full QSK operator. That is
 simply not the case: the problem starts showing up around 35 wpm, in either
 full or semi-QSK.
 
  The only ways to mitigate it are to use QRQ mode or to use manual PTT
 rather than any form of QSK.
 
  If the fellow who started the thread never operates CW over 30 wpm, or
 if he gets used to the limitations of QRQ mode (as I have) or if he uses a

[Elecraft] KPA500 270V fault and 'cure'!

[Stephen Prior]

I just had a 270V fault come up on the KPA500.  It's sorted now (I hope!)
but I'm a little confused as to how it happened, although I do have a
theory.

I was fiddling around the back of the amplifier trying to retrieve a mains
multiblock which had fallen off its usual perch.  The amplifier was on
OPER.  Suddenly there was a buzzing and the FAULT light lit, along with the
270V warning. I was able to halt the buzzing by switching back to STBY.
However, when I went to switch off the amplifier with the ON button on the
front, the amplifier went into hard fault mode again and my only option was
to use the main switch on the back.

However, when I switched back on again, effectively cycling the mains power
(manual page 13, just to prove I have RTFM), I still had the 270V fault
upon returning to OPER mode.  Once again, the only way out was turn off at
the back.  At that point my wife called me for supper.

When I returned, I decided to remove the top cover just to check the safety
interlock - all was well and still intact, the microswitch making a
reassuring click.  Put the top cover back on, fired up the amp again and
all is well.

Is it because when the amplifier is switched off from the back without
first turning off at the front, the capacitors remain charged and the
KPA500 is not seeing a mains power on/off/on cycle?  Perhaps these
capacitors discharged sufficiently during supper for the power cycle to
reset the KPA500?

I'm just grateful it's still working :-)Thought I would share in case
anyone else hits the same problem.  I can only imagine that I momentarily
knocked the IEC main plug in the back of the KPA500 when I was fiddling
around.  Should have switched it off first!

[Elecraft] KAT500 memories not erasing

[Stephen Prior]

I must be doing something stupid, but here goes...

I updated to version 1.63 earlier today from 1.58.  I have the latest
firmware versions on both the K3 and the KPA500.  To try out the new faster
tuning algorithm I tried to erase the memorised tune settings using the
KAT500 utility (latest version).  Choosing all bands and ANT 1 within the
utility I clicked on Apply and the software thought about it for a few
seconds before returning the OK button to use.  However, the KAT500 appears
to still have all of the original tune settings.

It's the Mac version of the utility.

It's not exactly show-stopping but I'm curious as to why I appear to have
been unable to erase the memories as has been suggested.

Re: [Elecraft] KAT500 autotune

[Stephen Prior]

An ingenious idea but I think there is a flaw in the argument, in that at
the position of the K3's ATU there will be a different impedance to match
than is the case at the KAT500's position further along the line.  Not only
will the impedance move around the Smith Chart a bit but there is also the
input impedance of the KPA500 to consider.  Maybe in practice all of the
above may have a negligible effect, but I somehow doubt it.

 for dry and one for wet WX) You have all shades in between, so once in a
 while You are going to have the relays going crazy again. At least it
 happens to me.
 This made me think if it might be avoided keeping in mind that the K3 ATU
 does the tuning a lot less noisy.

 I think others have suggested a firmware change making autotune of KAT500
 initiate from the K3. This may be an interesting way to get rid of the
 clickety-clack of the KAT500 if done as follows when selecting TUNE on the
 K3 (new mode: KAT500):
 - KAT500 enter bypass (KPA enters STBY) and K3 performs the autotune
 - K3 ATU config transfers to KAT500
 - K3 ATU changes to BYPASS
 - KAT500 changes to MANUAL
 if the cables from K3 to KPA are not so good it may be that the KAT needs
 to fine tune. So a fine tune of the KAT might be a good idea.

I seem to remember reading that the order of turning on the K-line is

K3/P3.  I have not had any issues doing things in that order.  Maybe this

  The K3, KPA500, and KAT500 all have new beta firmware releases
 available. All three must be updated to take advantage of these major

 re-tuning and faults have been fixed.
 
  We've also added a new feature that allows the KAT500's network settings
 to automatically track the K3's VFO frequency. The K3 will send frequency
 information over the K3's AUXBUS line, and the KAT500 will select
 previously memorized tuner settings as you move across the band, or when
 you point and shoot to work a packet spot.
 
  If you have any difficulty with the instructions below, please post a
 question to the Elecraft list, or contact customer support.
 
  73,

  N6KR
 
 
  * * *
 
  Instructions
 
  1. Download the new beta firmware for each device from the applicable
 software pages on our web site.
 
  NOTE: Follow the instructions for beta firmware releases when installing
 software in subsequent steps.
 
  2. Using K3 Utility, save your K3's configuration. Then install K3 rev.
 4.83.
 
  3. Using KPA Utility, save your KPA500's configuration. Then install
 KPA500 rev. 1.37.
 
  4. Using KAT500 Utility, save the KAT500's configuration. Then install
 KAT500 rev. 1.58.
 
  
 
  5. (OPTIONAL) Set up the K3 to send VFO information to the KAT500:
 
  (a) Make sure the K3 and KAT500 (and KPA500, if applicable) are
 connected via the accessory cable. The AUXBUS line must be connected, as
 well as the four BAND lines, which we use to qualify the AUXBUS frequency
 data. If you've built your own cable and omitted the AUXBUS or BAND lines,
 you may need more wires for this to work.
 
  (b) At the K3, locate the CONFIG:KAT3 menu entry. Tap the numeric keypad
 '1' button (also labeled A/B). You should see KAT500Y or KAT500N with
 successive taps. Leave it on KAT500Y (the Y means Yes, send VFO info to
 the KAT500). Exit the menu.
 
  (c) Verify that as you tune the K3's VFO, the KAT500 selects the
 appropriate LC settings. This occurs after you *stop* moving the K3's VFO
 for about 1/2 second. You should hear one or more relays clicking at the
 KAT500 when entering segments that have different LC settings.
 
  
 
  6. (OPTIONAL) In conjunction with the new VFO tracking feature, you may
 find it a good idea to retrain your ATU on 8 or 10 kHz boundaries on 160
 meters, and every 20 kHz on 80 meters, particularly if the antennas have
 sharp SWR curves.
 
  (a) Use the KAT500 Utility, Configuration tab, Edit Configuration, Erase
 Memories to erase memories on bands that have sharp SWR curves (e.g. 160
 and 80 m).
 
  (b) While you're in the Edit Configuration dialog, make sure the
 Amplifier Key Interrupt power setting is 1500 for a KPA500. If not, click
 Optimize for KPA500, then Apply.
 
  (c) Change the tuner's mode to MAN. In mode AUTO, the KAT500 will start
 a full search tune whenever the SWR reaches a threshold. If you're
 pretuned, that should be unnecessary and is probably undesirable. Mode AUTO
 is useful for remote tuners where it is inconvenient to press the ATU TUNE
 button when you need to.
 
  (d) Using exciter power only, perform a full search tune at 10 kHz
 increments on 160 and 20 kHz increments on 80 meters. Do this for
 frequencies where you don't want the ATU to enter full search tune when
 you next QSY there. This is best done by setting the K3's TUN POWER to
 about 20 watts, HOLD the K3 TUNE button to generate carrier, then tap the
 KAT500 TUNE button. It may take a while for a few settings, but often it
 will start close and won't take long at all. It depends on the SWR curve
 of the antenna on that band.
 
  (e) IMPORTANT: When you first visit a new frequency, the ATU will first
 snap in a setting from a nearby memory. It may be a memory you've used
 before with a different antenna.  If the setting is inappropriate for the
 current antenna, the SWR will be high, and in mode AUTO, the tuner will
 need to retune, which requires more or less constant carrier, not SSB
 speech, not high speed CW.

Re: [Elecraft] AF recorder function

[Stephen Prior]

Hi Don,

All I want is to have the AF REC come on when I turn the rig on, rather
than having to remember to push the appropriate button.  I'm not worried
about the fact that it only records for a relatively short period before it
overwrites what it has already recorded.  I just want to be able to check
back a few seconds - did the DX station really get my call right etc...  If
I haven't remembered to turn AF REC on, I can't do that.

Re: [Elecraft] K3/KPA500/KAT500 SWR Problem WHITE SMOKE!

[Stephen Prior]

Good news Ray, I swear by Ian's choke design.  It has worked miracles
here.  As I mentioned in an earlier post I went straight to the 3 section
GM3SEK choke, in fact two of them, one at each end of the coax section.
Works a treat.  I can't speak highly enough of the KPA500/KAT500
combination.

73 Stephen G4SJP


On 15 January 2014 15:59, Ray Coles raycole...@gmail.com wrote:

 I am pleased to relate that I seem to have finally nailed this problem, and
 I think many of those who gave me helpful advice and the Elecraft design
 team will be interested in learning what the final diagnosis and cure
 turned
 out to be. A quick recap: About 2 months ago, operating at about 75W into
 my
 trusty OCFD, the KAT500, KPA500 and K3 SWR readings shot up into the red
 and
 all DX fun ended abruptly. The problem remained, so I started looking for
 the culprit: I pruned tree branches that were touching the antenna after a
 recent storm. No joy. I replaced my 300W 4:1 balun at the end of my RG58
 buried coax feeder with a 1KW unit. No Joy. I replaced the buried RG58
 feeder with UR8 which took a new route, avoiding burial. No Joy. I dropped
 the antenna and replaced the 300ohm twin feeder from the balun to the T
 piece, the T piece itself and the antenna wire and dog bones. No joy. At
 this point I consulted the Reflector Oracle, and the most common response
 was common mode current on the feeder caused by OCFD unbalance. I did
 research and decided to build the renowned GM3SEK choke balun. I chose the
 mid range version which covers broadly 5-14MHz and installed it just south
 of my 4:1 balun at the North end of the feeder. No Joy. Further ideas from
 reflector pundits suggested that it might still be common mode, but coupled
 from the antenna into the feeder where my GM3SEK choke wouldn't help.

 Fortunately I had bought enough Fair Rite oval cores to build all three
 (Lo/Mid/Hi) balun designs, so in a final roll of the dice I built the two
 core Hi Band balun and installed it in the Shack next to my rig. The hi
 band
 version has a fairly flat impedance curve and reaches down to 7MHz and up
 to
 30MHz. IT WORKED! I have run 100W on all the bands from 40m to 10m and I
 have seen no run away SWR readings. My 25W tune value stays rock solid. As
 a
 final push-my luck step I turned the KPA500 to operate and ran 400W SSB. No
 Sweat! All of these things were no-nos yesterday.

 The final diagnosis is as follows: Some simple fault perhaps a connector or
 a crimp termination caused the first occurrence. I then compounded the
 problem by replacing my buried RG58 with an unburied and, I now see, a more
 parallel routed feeder which locked the problem in via antenna coupled
 common-mode currents. This also explains the fact that I could keep
 operating provided I kept power below 40W. Some respondents felt there was
 a
 KAT problem which compounded the problem, I always felt that the problem
 lay
 outside the shack but that maybe, just maybe, the KAT might be a bit
 sensitive to the problem. The only thing I would ask the Elecraft design
 team to investigate is whether the SWR circuitry has to respond to the
 common mode currents as it does. Probably not a firmware issue though!
 Thanks to the many people who made so many helpful suggestions.  E Pluribus
 Unum!

Re: [Elecraft] P3/VGA question

[Stephen Prior]

I think that there are a number of us hoping for more functionality from
the P3.  This does get addressed in this list from time to time with the
occasional tantalizing glimpse of what might be just around the corner.
For me, I would like the P3's display to show other information pertinent
to the K3 - perhaps a data display with more lines than the SVGA option can
offer - or K3 operating parameters for example, without the need to go
through the K3's menu system.  Then of course, there is the hole in the
back panel that is crying out for a socket!

 Just curious if it is within the realm of reason to have completely

 know they're slightly different now, since there's a longer waterfall on

 at the P3 unless I need to push one of it's control buttons.  Curiously, I
 was originally hoping for a P3 version that did not even HAVE an internal

 external monitor shows a more typical fill in under the line.

Re: [Elecraft] K3/KPA500/KAT500 SWR problem UPDATE

[Stephen Prior]

Ray,

Very interesting stuff, thanks.  As the user of an off-center fed doublet
myself, I was initially very nervous of running more than my usual 100W.
As it happened, I need not have worried, as I have never experienced the
problems you describe with the arrival of the KPA/KAT500.  The reason may
well be the choking I use on the doublet, and I suspect that you are on the
right track here.  I took a belt and braces approach to this a year or so
ago.  I have a drop of about 20 feet of 300 ohm 'balanced' feeder whereupon
a conversion to heavy duty coax is made via a choke balun based upon
GM3SEK's work - using the recommended ferrites, combining three different
chokes in series to cover the whole of the HF range.  It's very heavy and
physically quite large so I have it mounted in a box on a flat roof about
20 feet above the operating position.  The coax (short run) goes down to
the shack and through another 3 section choke balun on the back of the
amplifier.

GM3SEK's article is well worth a careful read.  Miscellaneous bits of
ferrite are likely to do nothing, and the combination of coaxial coils and
ferrite in Ian's design works extremely well in my experience.  An added
bonus was that it also reduced my local noise floor considerably.

http://www.ifwtech.co.uk/g3sek/in-prac/index.htm#1005

...is all you need.  In the UK you can get the ferrites from  Farnell in a
couple of days although they are quite expensive.  Accept no imitations!

 As the original poster under this heading I figured you might be interested
 to know what I have achieved so far, even though I am not yet ready to send
 the white smoke up the chimney.  Briefly, my problem was that my KAT500
 would go into uncommanded tunes during a QSO, usually on digital modes.The
 practical result was that I had to restrict TX power to less than 40Watts
 on
 most bands to avoid a burst from the Chicago Piano in the KAT. I had
 assumed
 an antenna/feeder problem and had changed every last connector, wire, balun
 and insulator in my system before asking for help from the Reflector Brains
 Trust. All of the other people who subsequently reported a similar problem
 made me feel a little better, and I also received a lot of diagnoses and
 practical advice which I have followed or will follow soon. One of the
 simplest was from Ron WB4OOA: Carry out a K3 Gain Calibration via the K3
 Utility (I had to download the latest Utility version to make this work
 properly) then Install the KAT500 V1.42 Beta (Not quite as easy as it
 sounds). After this things were better, and my power setting on the K3
 always appeared on the KPA500 wattmeter. I could now operate at higher
 power
 on some bands but had to stay below 40W on 40m. I had also adjusted the per
 band retune trigger SWRs upwards via the KAT500 Utility which also helped a
 little.

 I remain convinced though, that the basic trigger problem lies with the
 antenna system (an OCF multiband dipole) and I am continuing to work on
 this
 aspect using my analyser. Why it should have suddenly kicked off after many
 months of solid performance, and why changing everything hasn't yet cured
 it
 remains a mystery. My next steps are to try a choke balun on the feeder
 (parts now to hand) and to prune the antenna to get a better resonance on
 the bands of interest. Now if only this darn rain would stop! (I still
 think
 some tweaking of the KAT500 software might also help!)

[Elecraft] K3: Internal keyer misbehaving

[Stephen Prior]

Occasionally, at 100W I get the internal keyer locking up, sending a string
of dits.  Having now built the KPA500/KAT500, it is now happening often
enough for me to worry more about it - it is, in fact, quite embarrassing!
When it happens it always sends dits and can be stopped by a further tap of
either paddle (Begali).  I'm using the cable supplied with the Begali, with
it wrapped around a 'significant' ferrite (appropriate material type) just
before it enters the socket on the back of the K3.

Despite the origin of the cable, I shall try another one that I know is
well-shielded, but wonder if anyone else has experienced this problem?

Re: [Elecraft] P3 Problem

[Stephen Prior]

I get that too, but usually just for 2 or 3 seconds and sometimes not at
all.  I have never got my head around it, but I think it got worse after
fitting the SVGA board.  That leads me to another 'feature', in that the
SVGA screen will occasionally do a complete refresh of the waterfall,
without me touching anything else such as the VFO.  It's as if a buffer
which is much bigger than the screen data is being flushed, leaving no
history in the waterfall at all.

I can't imagine myself being without the P3 now, however!

 I am using a P3 with the SVGA option. It is connected to a K3. I find that

 information. It's almost like the P3 is suffering from data overload,
 finally processes it, and gets back to normal.



 This is particularly annoying as one cannot spot where the DX is listening
 in said pileup because the screen is essentially frozen and does not
 display
 stations real-time until it unfreezes. This happens regardless of mode
 (CW, SSB or RTTY). In RTTY this freeze time also locks up the USB
 keyboard.


 The problem does not appear to be RFI related, as I get it regardless of
 the

 Any idea what's going on?

Re: [Elecraft] [KX3} Accuracy of clock

[Stephen Prior]

Mine will drift a few minutes over a few weeks, but I do agree that 4200s
in one week points at a problem somewhere.

 With certainty, a 4200+ second deviation in a week's time is pathological
 and should not be dismissed with only set-it-if-you-need-accurate-time
 advise.

 Something abnormal has caused it.  Time it again over a week to see if
 it's hardware, or something that you might have inadvertently caused.

Re: [Elecraft] KX3 and P3 question

Graham,

Elecraft did write, in an email a year or so back, that they might be

Whether it is still on the cards I don't know.

[Elecraft] K3 buzzing on key down

[Stephen Prior]

I'm getting a fairly loud buzz, almost an arcing sound coming from the
K3/100 on key down on CW, just some bands, 15m for instance. I'm wondering
if I have a ferrite bead vibrating somewhere.  I have had the transceiver
now for some years and have never heard it before.  Has anyone else found
this?  It doesn't do it all the time so is rather difficult to pin down.
I'm getting full power out without any problem.

Thanks for any advice,

  I'll inject some science into the discussion based on my profession of
 electroacoustics.  Human perception of sound is logarithmic, both with
 respect to amplitude and frequency (pitch). Another way of saying it is
 that our ability to separate two notes is a function of their percentage
 difference.  For the same bandwidth in Hz, we have better discrimination
 between two note a lower frequency, because the difference is a higher
 percentage of the frequency.  So it's easier to discriminate a 100 Hz
 difference at 450 Hz than at 750 Hz. That's one good reason to use a lower
 pitch.
 
  Another is that for most (but not all) of us, hearing loss is greatest
 at higher frequencies, so we old farts tend to have somewhat better hearing
 at 450 Hz than at 1 kHz.  That's not universal though -- those of us who
 were exposed to noise (usually at work) that's much louder at some
 frequency(ies) tend to develop notches in our hearing at those frequencies.

Re: [Elecraft] K3 Current Drain When Off

My Fluke 73 reads 4.3mA on the 300mA range and 40mA on the 10A range, which

the 'full scale' value is so very much higher than the current that you are
trying to measure.

Ron,

I'm not sure if your posting was directed at me or not, but I didn't
mentally move the decimal point :-)  It was a fundamental limitation of the
(good, I thought) DMM I was using.
It just goes to show that you can't always believe what your measuring

 almost 40 mA (38 mA in my case) that is produced by the KPA3. I

 virtually zero.

 The measurement was made by placing an ammeter in the positive lead from
 the
 power supply. Nothing at all connected to the K3 except for the power
 cable.


 It's not an issue to me because I switch off the dc supply when leaving the

 Subject: Re: [Elecraft] K3 Current Drain When Off

 Jim,

 Here's one possible explanation:

 The external power supply must drop all the way to zero V, as must any all
 K3 I/O signals. This may have implications for attached equipment.

 If there's any residual voltage on the supply or I/O lines, even 1 V, the
 K3
 may not turn off all the way. It turns out that the brown-out detection
 circuitry on microcontrollers can be confused at some power levels that
 are
 low enough to look like a brownout but not high enough to properly power
 the
 detection circuitry. Under such conditions the MCU may continue to run on
 power-down via the on/off switch, resulting in the radio drawing an
 unpredictable amount of current.

 If residual supply or I/O leakage isn't the cause, then I suspect a
 problem
 with your K3's on/off circuitry or possibly even the PA module. (You could
 test the latter theory by unplugging the KPA3.) Every K3 we've tested
 drops
 to a very small number of milliamps of current drain when off.

Re: [Elecraft] KX3 S meter calibration

We are waiting for the S meter absolute mode to be incorporated into the

 accurate up

 I would have expected it to be calibrated with both the pre-amp and

 Also, when the firuware is available that automatically accounts for

Re: [Elecraft] KX3 power reverts from 10W back to 5W

[Stephen Prior]

I have found that with even a freshly charged 7Ah battery that the power
folds back, on some bands especially, even if the internal atu has found a
good match. However, in almost all cases setting the power output to 8W
rather than initially 10W it doesn't happen as much, at least not until the
battery voltage has fallen well below 12V.

 Arno,

 Sure someone from Elecraft will respond with a technical
 explanation...sounds a bit like default behaviour to me and also shows
 there is a difference in the battery and the internal PA voltage and you
 are maybe close to the fold back voltage.

 If the supply voltage drops below 12V (I use 7AH SLA batteries so see this
 often) then it can be lower at the PA internally (c11V + a bit) when it is
 the KX3 folds back to 5W, no real warning it just does it. I found it a bit
 annoying when I knew mine was running hot but then the KX3 was designed
 with battery /P operation in mind (I assume).  The KX3 does the same thing
 to protect the KX3 if the PA gets too hot (you could try this, not sure it
 will damage the KX3 so be warned, I did this when I fitted a heatsink to
 reduce the issue... set power out to 10W, key down or send dah dah
 constantly with a keyer for a few minutes into a dummy load (not on air!)
 to make it fun do this in bright sun and watch the PA temp rise and rise
 and the rear metal panel gets hot, eventually the temperature will exceed
 what is 'safe' and the power will reduce, same thing happens for excess
 current say if a PA transistor is failing or an antenna impedance/VSWR
 changes there are multiple reasons and a few other situations all are
 designed to protect the KX3.

 You could monitor the KX3 reported PA temperature and the KX3 reported
 voltage and see when it happens so you know when to adjust the power out
 level yourself or know when it is likely to happen.

 I have a really nice light weight /P switch mode mains power supply it
 provides 12.2V (was for a CCTV camera) the KX3 will never exceed 8W out
 with it on CW, if you set 10W it folds back immediately to 5W.

 The Volt meter showed 12.3 V at RX and dropped to 11.7V at TX. Was that
 the
 reason (getting below 12V)?

 Was the PA getting too hot? It never went below 5W.


 Thanks for any tips,

Re: [Elecraft] K3 RX Audio

[Stephen Prior]

Trevor

My #930 has always sounded nice to me with a pair of high end sennheiser 
headphones with far less background hiss than either the ts480 or IC7000 which 
preceded it. I did the dsp board swap a couple of years ago and that made it 
even more pleasant to listen to. In my opinion, even for its size, the built in 
speaker in the k3 is disappointing and I don't use it.

 Hi All
 
 I am allmost ready to order my K3 but I keep reading about people that are 
 unhappy with the RX audio,
 
 Is this still a problem or has there been changes made to slove it, Can 
 someone point me to a good guide on how to set the RX up to remove the harsh 
 sounding audio.
 
 I will mainly be using a headset as DXing is my main interest.

Re: [Elecraft] looking for iPad software

[Stephen Prior]

Bill,

The Hamlog app:

http://pignology.net/hamlog.html

can be as simple or as powerful as you like.  And if you team it up with a
'pigtail' from Pignology (check out the same website) you can even
wirelessly connect to the KX3 to get full transfer of mode, frequency etc.,
in addition to full rig control if that's what you want.

Re: [Elecraft] KPA500 - power out question

[Stephen Prior]

Bill,

I suspect it has more to do with the default reply nature of the group, in
that replies are sent straight back to the originator of the message rather
than to the group itself.  It's not typical of the way that groups tend to
be set up these days and so catches us all out from time to time!

If I may add my indirect experience of the KPA500 in that a good friend of
mine bought one, he too very quickly followed up with an order for the
KAT500 and is, I believe, very happy with its performance.

Re: [Elecraft] 6 m reception comparing with KX3

[Stephen Prior]

Skip,

I can hear no difference on FM between the K3 and the KX3.  1uV from the
XG3 on 50.120 MHz gives much the same level of smooth noise from both
radios.  My KX3 is #434 so yours is not an 'age' issue,  there must be
something else wrong.

73 Stephen G4SJP


On 4 May 2013 02:56, Skip Davis skipn...@yahoo.com wrote:

 John and the group,

 From my experience I own both a K3 and KX3. I have found that the K3 hears
 better on 6m FM using the same antenna switching between both rigs. I have
 only used both on 6m in FM mode only in the 53 MHz range for a local
 repeater.
 The repeater will be S9 and clear on the K3 and will only be an S3 and
 noisy to the point it is almost unintelligible. On transmit running at 8
 watts both rigs I'm told are full quieting into the repeater.
 At one point before a firmware update I could only tell on the KX3 that
 the repeater was accessed and the beep tone was clear but audio sounded
 garbled. Any signal over S5 was clear.
 I am using all the preamp settings for 6 as outlined in the manual and I
 have the latest DSP and firmware loaded. Now having said all this my KX3
 serial number is under 1000 so I don't know if there was any changes to the
  unit that my have addressed this or that mine is unique.
 I did noticed that on the schematics for the bandpass filters there is a
 outline for a LNA in the 6 meter bandpass filter. So I am wondering if this
 is already thought of and the boards are setup to accommodate one in the
 future, I hope so.
 Also as a side note when I hook up my FT817 to the same antenna the
 repeater is S9 and full quieting.

Re: [Elecraft] Free DV (digital voice as reported in QST-Aprilissue)

[Stephen Prior]

It took some finding on the Elecraft site and in the end I had to use the
site's search tool, but the information (and more besides) is at
http://www.elecraft.com/K3/k3_operating_tips.htm

I agree that something so important should be in the main manual.

On 3 April 2013 19:47, Don Wilhelm w3...@embarqmail.com wrote:

 Well, I 'thought' was in the manual, and it *should* be.

 Lyle has explained several times here on the reflector (and he should
 know, he designed it) that the onset of ALC action is at the 5th bar.  The
 bars below that do not indicate ALC action at all.

 Due to the way the K3 controls power, if you do not have sufficient audio,
 the K3 will increase power (thinking there is not enough drive) and you
 will find your power drifting upward as you transmit.

 So adjust for 4 bars on the ALC meter (that is *no* ALC) so your power
 will be uniform throughout the transmission.  With the K3 you must have
 sufficient audio drive to allow the power controls to work as they should.
 Contrary to the advice given for most transceivers (which do not control
 power in a closed loop), the K3 power will behave strangely if you use that
 advice - which is to set the power for maximum and use the audio drive to
 control the power output.  That just will not work with the K3.

Since this is just another digital mode, why would you not set the K3
ALC indication as specified for other digital modes.  4 bars on the ALC
meter with the 5th bar flickering.

If you do not do it that way, the K3 will power hunt and you will not
have consistent power output.
Bring the audio up as indicated in the digital operation section of the
K3 manual and set the power knob for the desired power output.

 Is it perhaps gain reduction caused by extremely strong signals in the IF

Re: [Elecraft] Newest P3 FW Upgrade (Workaround)

It took me three attempts, failing on the SVGA load the first two times,
even after switching both K3 and P3 off and then on.

I don't know whether this is significant but I had the SVGA disabled (I
have no monitor connected at the moment) the first two times but then
decided to turn it back on and the SVGA loaded okay  - it could have been
coincicidence of course.  I had similar issues last upload as well which is
very much in contrast to the troublefree uploads I have done on the K3 and
KX3 over the years.

  Read almost all the posts and one stuck with me - the one who stated
 everything worked fine on a Win7 machine using the same cable.

 On a lark, I started my Win 7 virtual machine through VMware, downloaded
 and installed the P3 Utility, and connected to the P3 - voila, it worked.

 This is going through the exact same machine, using the same USB adapater
 with the USB adapter plugged into the same port. In other words, I did not
 change a thing. This VMware machine has caused me all kinds of grief and
 has only recently started working somewhat reliably. However, it allowed me
 to load the firmware.

 The only thing different was the fact that I received FW 1.26 instead of
 1.25.

 None of this answers why the FW load (either 1.24 or 1.25) always stopped
 at the same point in the load on the Mac version. I have no idea...

 Thanks for the suggestions.

 I absolutely cannot upgrade to the latest P3 FW (1.25). I had similar
 issues with 1.24, but it eventually loaded after several attempts.

Re: [Elecraft] Enabling VOX via a macro

[Stephen Prior]

Hi John,

That confirms what I thought.  I don't want toggle as the vox may already
be on and implementation of the macro would only serve to switch it off
again.  What I am doing within the control software is setting up one
button mode changes along with filter settings, P3 span width, etc.  As
fldigi and Rumlog are not completely integrated I don't have the option of
CAT control for PTT in the data modes, hence the need for the VOX to be
enabled.

Having said that, it's a very minor irritation that I can easily live with!

Thanks for taking the trouble to reply,

73 Stephen

 I'm not sure exactly what you are trying to do but swh09; is the only

 there is for setting vox on and off, a toggle. In my RUMlog I have a macro
 to do just that. So if it's already on I can turn it off and vice versa.

Re: [Elecraft] K3 Reduced BW FSK

[Stephen Prior]

Mark,

You will have to enlighten us (well, me anyway) - just what pre-beta
software are you referring to?

 Just a report that I used the pre beta low bandwidth fsk software on both

 With the ever increasing popularity of rtty contesting, improvements like

Re: [Elecraft] P3 generates noise on 144 MHz

[Stephen Prior]

I've had absolutely no issues with my P3 and a 2m ssb transceiver just
inches from it.  This will doubtless be the exception rather than the
rule.  There must be something not quite right somewhere.

 I'd be interested to see the EMC Test Report on the P3, required for

 Elecraft could comment please?. I was thinking of picking up a P3 at Dayton
 but may hang fire...

 As hams we have no right to complain about PLT, Plasma TV etc if we don't

  I recently installed the K144XV 2meter converter in my K3. I could work
 strong stations on 2m with no problem, but weak stations were swamped by
 noise which was S9 over the entire band. My P3 was showing that the noise
 consisted of carriers every 19KHz with lots of buzzy noise in-between. I
 soon found the source of the noise. It was the P3 !  When I turned the P3
 power off, the noise completely disappeared. With the P3 on and the antenna
 replaced with a dummy load, the noise also all but disappeared. When I
 removed the RS232 cable and the IF cable from the P3, leaving only the
 power cable, the noise persisted at the same strength. So it appears that
 the P3 box is radiating this noise directly into my antenna. My antenna is
 a 2meter ground plane on the roof of my shack. It is about 8 feet from the
 P3. Obviously a solution would be to move my 2 meter antenna well away from
 the shack. I was not able to find any mention of this problem in the
 archives. Is there something wrong
  wi
  th my particular P3 or do they all do this?

[Elecraft] P3: Enabling SVGA makes display jerky when using narrow span

[Stephen Prior]

I have not noticed this before, and I often reduce the span down to 5kHz or
so when I am calling a DX station spilt.  On both the P3 and the external
1024x768 monitor, instead of a nice smooth waterfall, it is jerky in its
motion and the only setting that I can find to prevent this happening is
the one that disables the external display.

I am running firmware version 1.25.

Any ideas?
