Re: [Elecraft] kx2 utility for linux on Raspberry Pi

[Bob Nielsen]

The Linux source for the KX2 utility could probably be compiled on a 
Raspberry Pi.  I realize that the source code has not been (and probably 
won't be) released but presumably someone at Elecraft would have a RPi 
and be able to create an ARM binary that could be made available.

[Elecraft] Review of the KXPD3 ker

[Eddy Avila]

I just bought the KXPD3 for my new KX3


First the disclaimer.I'm not a hotshot CW op, maybe back in my novice days 
as wn6sdw. Now, I'm lucky to inch towards 20wpm these days, but only when the 
going downhill and the wind is at my back. And no wine.


With that said, I like this little bugger. For the price, the KXPD3 fits 
perfect on the front of the KX3 and is very convenient to use.


Its definitely not your $300 ~ $500 key performance. the KXPD3 is definitely 
not the smoothest key I have used, but more than adequate for field operation, 
or just relaxing working a QSO or two.


I also like use b mode for this paddle.


The cool thing is that Elecraft kept the external paddle port live so you can 
have to keys connected at the same. I use the Kent TP1 and the k1el  Winkeyer 
for contesting.


Cheers all

[Elecraft] Elecraft CW Net Announcement

[kev...@coho.net]

Good Evening,

The sun was quite active during the early part of the week. It has since 
quieted.  Last Sunday the sfu was over 100. Currently it is hovering 
around 70 again where it seems to have been stuck all winter.  The 
strong auroral oval tells me there are ions coming in so the lower bands 
should be noisy but OK. The ELVE in Eastern Europe was interesting.  I 
doubt the lightning ever gets that intense in the PNW.


The daffodils are budding and will open in a week.  That means the last 
snow is due.  Before noon we got half an inch of pellets but we normally 
get a few inches once the daffodils start blooming.  I think their 
clocks are set for warmer areas.



Please join us tomorrow on:

   14050 kHz at 2200z Sunday (3 PM PDT Sunday)
7045 kHz at z Monday (5 PM PDT Sunday)

73,
Kevin. KD5ONS

Re: [Elecraft] ICOM Remote Antenna Tuner

Yes, that is correct. Just feed it some RF and if the SWR is above

There we agree ... where the monitor level is set to be usable in the

are turned on.  However, if one is using low sensitivity headphones
with the speakers turned up high *and* high mic gain, one can cause

I can't honestly think of any reason one would want TX monitor audio in a

it's a good idea.  I can't say I've ever noticed it until doing this test.
Whether it results in audio feedback depends on your monitor level, your
mic, your speakers, and the placement of mic and speakers relative to each
other.

I think some of the misunderstandings on this thread are because the front

1) the original poster is using the front panel PHONES jack, and has

used to - i.e., plugging in the phones mutes the speaker. In this case, if
Monitor is on, it comes through phones OR speaker, whichever you're using
at the time.  There is no provision to enable/disable Monitor based on
whether the front panel phones are plugged in, which is what he wants.

the phones as expected. If SPKR+PHONES is set to yes, the RX audio comes
through the speakers, but the transmit Monitor audio does not.


At least, that's the behavior with my K3, MCU version 5.57.  I just tested
the two scenarios above.  For the record, my normal configuration is to
use
the rear panel phones and mic jacks, with SPKR+PHONES on.  I do have PF1
set to toggle that off, but rarely do, since I'm usually alone in the
shack.  I have yet to hear any kind of audio feedback when transmitting.
I
have no idea if the behavior is any different using the front MIC jack, as
I never do.

I'd be interested to hear if anyone has a different experience.

Incidentally, while testing option 1 above, I unplugged the phones from
the
front and cranked the MONITOR until it was unpleasantly loud from the
speakers, but got no feedback howl, but that may just be a function of
placement.

It is *not* the firmware - it is the *hardware* that does not support

I studied the K3 schematics a few days ago. I've just studied them

On receive, the rig is capable of muting the speakers when the

the two audio amplifiers having parallel inputs.

I have used an AH-4 for many years, with a 706MKIIG and with various other 
manufacturer's radios, including now a K2.  Other than the limitation to ~125 
watts, these are excellent.  I only run 5 watts so it is not an issue.  I do 
not recall a situation where the AH-4 would not give a useable match, provided 
I provided it a plausible antenna.  I use a separate SWR/watt meter that shows 
it working.

The momentary switch  is push on, release off, no time specified.  Pushing the 
button signals the AH-4 to run through its paces for a match.  Most often, it 
is very quick.  Occasionally, when you have gone from, say, 15M to 80M, it 
might take a little longer, but never more than several seconds.  If no match 
can be found, it just stops.  Either way, you stop the power. I wouldn't let it 
just run like that, but have never heard of damage because of it.  You need to 
reduce power with non-Icom rigs that don't do it automatically.

You might join the Icom tuner Yahoo group, if you can stand Yahoo.  Lots of 
user experience there.

I've never seen a store bought controller for the AH-4.  Where have you seen 
them?

Re: [Elecraft] K3S SSB TX monitor - feature request

[Luis V. Romero]

I will then restate my opinion:  

I and just about EVERYONE I have personally dealt with in my professional
experience with broadcast booths for recording voice over, technical
intercom, IFB feeds, musical talent and singers prefer to have SYNCHRONOUS
VOICE sidetone in their ears.  Remember last New Year's Show on ABC-TV?  The
non singing Mariah Carey?  She had clean mix minus in the floor monitors,
but no earpiece sidetone feed :)  

But there are exceptions.  You may be one of them.

Ever watch a TV liveshot where the person on camera yanks out their
earphone?  They are probably being fed DELAYED audio over the IFB.  That's a
really bad thing!  Some delay is acceptable, and some on camera talent are
very good with filtering out the delay.  Most cannot. This has become a
nightmare now in Digital transmission with the added latency introduced by
modulation codecs. Gone forever are the days of feeding main channel with
IFB over ProChannel or 450MHz BAS transmitters (although there are still
some stations out there that do this... Its "traditional").

And I will agree with you on HT carrying hams.  Especially Digital
Modulation ones.  There is copious processing delay with Digital Modulation.
That would drive most people mad!

I can sense the K3 delay when listening to my processing in my rig's
monitor. I find it within my window of manageability and I like to hear
sidetone in my headset as I have been accustomed to by 41 years of using
headsets over RTS/Clearcom/Riedell intercom in broadcast control rooms,
never on speaker.  I could live without it...  But I prefer to have it.  

However, I can also see 2 frames of video to audio delay... It's a curse,
not a blessing in the digital world we live in today.

You mileage obviously varies from mine, Ron!  Viva le difference!

John, I have used both MFJ 993 and 998 successfully.  I have 12v for them and 
send one coax to them.   I don't rely on anything but sending 10 watts via K3, 
etc., to the tuner and await the OK SWR to reflect on my W2 wattmeter.  I 
currently only have the 998 in service.  I prefer the 993 as it takes less 
power to tune.  I am going to sell my 993 as it handles only 300 watts.  I send 
out 500 so cannot use it.  Hope this helps.

Subject: [Elecraft] ICOM Remote Antenna Tuner

I am looking at remote antenna tuners.  I have seen several controllers for the 
ICOM AH-4 tuner.  My questions are about operation with a K3s.
1.  Is there a limit to the time that 10w of RF can be sent to the AH-4
via the K3s Tune button?
2.  All circuits specify a momentary switch, but does momentary mean
0.1sec, 1.0sec or 5seconds? Does the time matter?
3.  When the complete signal returns from the AH-4 should the Tune RF or
the momentary be terminated immediately?
4.  Is there a combination of momentary or Tune RF that will damage the
AH-4?

I have an AH-4 which worked with a home built controller for some months, and 
then became operationally intermittent and final fails to work at all.
That makes me gun-shy, about buying another even though the AH-4 gets excellent 
reviews on eHam, almost all of which are based on an ICOM rig control.

Re: [Elecraft] K3S SSB TX monitor - feature request

[Ron D'Eau Claire]

With respect, it's all what you have grown accustomed to. The AM and FM
stations where I worked only had a speaker in the booth over which the DJ
heard audio from the disk on the turntable or rare network feed. He/she
never heard their own voice. 

Same was true in aircraft and military radio comms. And I doubt if many Hams
today carrying an HT are disturbed by not hearing their own voices. 

Sidetone in telephones was used to keep the person speaking from shouting
(as they did in early phones). The higher the sidetone volume, the quieter
the person would speak. We used that to great effect to tame a "shouter" in
bull-pen office environments. Unfortunately mobile (cellular) phones offer
no such benefit. 

My point is that I suspect that you are tapping into a change in recording,
broadcast and DJ work that is beginning to impact Ham operations.

All:

As a broadcast professional, I completely agree with the need to hear one's
voice as side tone in your headset while speaking.  Not hearing this does
make one feel deaf.  This is a common feature in professional intercom
systems as well as music performance monitoring for singers and
instrumentalists and even your telephone!  It's not really a "nice to have":
In my opinion, it's a "must have".

Re: [Elecraft] K3S SSB TX monitor - feature request

[Dave Fugleberg]

OK, I just ran my test again, but this time turned the monitor up all the
way, and i did indeed hear monitor audio in the speakers. I stand
corrected, and sorry for muddying the waters.

No, I wasn't confusing Phones and Line Out.

At any rate, at a 'normal' (for me) monitor level, it's not objectionable
(or even really noticable) in my external speaker. The only way I could
induce audio feedback was to hold the mic right in front of the external
speaker with MON set at or near maximum.

I can't honestly think of any reason one would want TX monitor audio in a
loudspeaker, but I guess that's the way it works, so somebody must think
it's a good idea.  I can't say I've ever noticed it until doing this test.
Whether it results in audio feedback depends on your monitor level, your
mic, your speakers, and the placement of mic and speakers relative to each
other.

On receive, the rig is capable of muting the speakers when the

There are switch contacts on the front panel headphone jack that enable

Is the audio input set to mic (not line in)?
Is the rig transmitting?

If these four conditions are all true, then mute the speaker amplifier.

That is still a failure mode for all those who leave a headset (or
headphones) connected all the time but only put them on when using
a headset mic.  There is no way for the rig to to know if the device
connected to the front or rear headphone jack are 1) headphones only
only or 2) a headset (with mic) and 3) if the headset mic is actually
in use.

Yes, it it possible to turn off the speaker amplifier but there is
still no sensor that will tell if the headphones are actually in use
just like the YaeComWood mechanical switch can only tell if a plug
is inserted in the jack.

The speaker amplifier is currently disabled whenever headphones are
connected to either jack with CONFIG:SPkR+PH=No.  Disabling the speaker
amplifier whenever headphones are connected to either jack is
*unacceptable* to hundreds of other users who routinely leave headsets
connected - particularly those who use headsets connected to the rear
panel jacks (and before you say "mute on connecting to the front
headset jack" - the headset switches are also connected in parallel).

You are looking for a solution that is unique to your own situation
and would inconvenience hundreds of other users simply because you
are too lazy to program a PF/Macro to toggle CONFIG:SPKR+PH when
you use a headset.

Re: [Elecraft] kx2 utility for linux on Raspberry Pi

[Bill Frantz]

It looks like gemu might work to run the utilities on a Pi. My 
experience with running Windows on a PowerPC Macintosh was that 
if the program wasn't too CPU intensive, the experience was only 
a little lethargic. Running photoshop was like watching paint 
dry. It's certainly worth a try.


Assuming gemu is not satisfactory, and given that Elecraft does 
not want to open source the utilities, I can see some options:


* Leave things as they are. People who use Pi based portable 
systems have to hope they don't need the utilities while away 
from their Intel based computer. Or carry extra stuff.


* Add a Linux ARM utility to the mix using their current 
resources. This option would probably be fairly easy, since most 
Linux just programs compile for both CPU architectures. There 
would still be extra testing needed.


* Look for a volunteer who will maintain the Linux ARM utilities 
under NDA.

2) If you use the REAR panel phones jack, the monitor audio comes through
the phones as expected. If SPKR+PHONES is set to yes, the RX audio comes
through the speakers, but the transmit Monitor audio does not.

Sadly, it will never work natively on a RPi as things are now.

The program is compiled for use on an X86 CPU, so even if the RPi had
WINE (and I doubt if that would run anyway) any Windows program would
fail due to the CPU architecture differences.

The Linux (and OSx) versions of the KX* utilities likewise are also
compiled only for X86 processors.

Lot's has been discussed on this list about this in the past, but
Elecraft and the software authors do not want to make the jump to the
Pi, or make the code open source so we could build it ourselves.  
Frankly, that's a crying shame, as it would be relatively trivial to
build the Linux version on the Pi, unless they are using some "secret"
third party libraries internally.

Running Qemu (or VBox etc) isn't going to help either, it they don't
emulate the X86 CPU as far as I know.

The exagear X86 emulator looks interesting, but I've not seen that
before or tried it.

Looking at their website, the cheapest version is only some £11 (UKP)
but emulates a Debian8 system, so you'll still be in Linux, but the
Linux versions of the util's should then work I suspect...

I run the KX3 and XG3 utilities on Mint (on a X86 laptop) and that's
based on Ubuntu, that is in turn based on Debian.  They work very well.

[Elecraft] ICOM Remote Antenna Tuner

[John Pierce]

I am looking at remote antenna tuners.  I have seen several controllers for
the ICOM AH-4 tuner.  My questions are about operation with a K3s.
1.  Is there a limit to the time that 10w of RF can be sent to the AH-4
via the K3s Tune button?
2.  All circuits specify a momentary switch, but does momentary mean
0.1sec, 1.0sec or 5seconds? Does the time matter?
3.  When the complete signal returns from the AH-4 should the Tune RF or
the momentary be terminated immediately?
4.  Is there a combination of momentary or Tune RF that will damage the
AH-4?

I have an AH-4 which worked with a home built controller for some months,
and then became operationally intermittent and final fails to work at all.
That makes me gun-shy, about buying another even though the AH-4 gets
excellent reviews on eHam, almost all of which are based on an ICOM rig
control.

Re: [Elecraft] K3S SSB TX monitor - feature request

[Dave Fugleberg]

I think some of the misunderstandings on this thread are because the front
and rear panel Phones jacks behave differently. Here's the deal:
1) the original poster is using the front panel PHONES jack, and has
SPKR+Phones set to NO. This makes the radio behave like most rigs we're
used to - i.e., plugging in the phones mutes the speaker. In this case, if
Monitor is on, it comes through phones OR speaker, whichever you're using
at the time.  There is no provision to enable/disable Monitor based on
whether the front panel phones are plugged in, which is what he wants.

2) If you use the REAR panel phones jack, the monitor audio comes through
the phones as expected. If SPKR+PHONES is set to yes, the RX audio comes
through the speakers, but the transmit Monitor audio does not.


At least, that's the behavior with my K3, MCU version 5.57.  I just tested
the two scenarios above.  For the record, my normal configuration is to use
the rear panel phones and mic jacks, with SPKR+PHONES on.  I do have PF1
set to toggle that off, but rarely do, since I'm usually alone in the
shack.  I have yet to hear any kind of audio feedback when transmitting.  I
have no idea if the behavior is any different using the front MIC jack, as
I never do.

I'd be interested to hear if anyone has a different experience.

Incidentally, while testing option 1 above, I unplugged the phones from the
front and cranked the MONITOR until it was unpleasantly loud from the
speakers, but got no feedback howl, but that may just be a function of
placement.

I studied the K3 schematics a few days ago. I've just studied them
again. Thanks for the reminder.

On receive, the rig is capable of muting the speakers when the
headphones are plugged in. This is quite normal. This happens despite
the two audio amplifiers having parallel inputs.

There are switch contacts on the front panel headphone jack that enable
the rig to 'know', firmware permitting, whether there's a jack plug in
the socket. There is also a line labelled MUTE1 connected to the pin 2
of the speaker amplifier U1.

So the hardware exists to enable the firmware (a) to know whether
headphones are plugged in, and (b) to mute the speaker amplifier. This
hardware is, AFAICS, used on receive. All I'm asking for as an option to
do the same thing on transmit, if a particular set of circumstances is true:

Is the rig on a voice mode?
Is the audio input set to mic (not line in)?
Is the rig transmitting?
Is there nothing plugged into the front panel headphone socket?

If these four conditions are all true, then mute the speaker amplifier.

[Elecraft] Feature Request

I'm losing track here. Am I correct in understanding:

1. SSB Sidetone required when wearing headphones.

2. SSB Sidetone not required when headphones are unplugged and listening 
to speaker.


3. SSB Sidetone automatically zeroed upon unplugging headphones.

4. Headphones are just that, not a headset with mic, and are plugged

inconvenient.

It is *not* the firmware - it is the *hardware* that does not support
what you call a "simple and common-sense requirement" and what others
call stupidity.  Perhaps you should study the schematic - at least of
the K3 which is published.   Notice on the sheets K3 DSP: CODECS and K3
DSP:DAC AUDIO the headphone/speaker amplifiers are fed *IN PARALLEL*.
LHPOUT/RHPOUT of U7 (the DC) goes through the audio lowpass filter to
U1 (speaker amplifier) and U2 (headphone amplifier) *IN PARALLEL*.
*THERE IS NO POSSIBLE WAY* to send monitor audio *to only* the
*headphone amplifier* (or for that matter *only* to the speaker).

Changing the operation of the K3/K3S to enable monitor *only* when the
headphones are in use would cripple current operation *and* make it
impossible to monitor data and/or CW modes via the speaker.

As pointed out by many in this discussion, using CONFIG:SPKR+PH by
assigning it to a PF/Macro key to turn off the speaker when one is
using the headphones is a useful alternative.  That solution has been
used by many operators who leave their headphones connected at all
times *for many years*.

When you start proclaiming a "simple and common sense requirement" take
a little time to determine if the hardware will even support such
nonsense!  Note: *none* of the YaeComWood transceivers support such a
"simple and common sense requirement" - they all feed their headphones
from the speaker amplifier through a mechanical switch and current
limiting resistors!  At least the K3 design has enough sense to shut
off the high current speaker amplifier when it is not needed!

Re: [Elecraft] K3S SSB TX monitor - feature request

[Luis V. Romero]

All:

As a broadcast professional, I completely agree with the need to hear one's
voice as side tone in your headset while speaking.  Not hearing this does
make one feel deaf.  This is a common feature in professional intercom
systems as well as music performance monitoring for singers and
instrumentalists and even your telephone!  It's not really a "nice to have":
In my opinion, it's a "must have".

Yes, the rig doesn't do this automatically.  Yes you have to twiddle some
knobs to get it done.  However, there is a very simple solution that allows
this feature requirement with ONE BUTTON PUSH.  Yes it requires an external
device, but it also adds additional flexibility and features for an
insignificant price vs the cost of the radio.

This device is the Behringer MIX800 modular 4 channel dual stereo input
headphone mixer.

I have had this device in my K3 audio path for 9 years now. I feed the line
out of the K3 into this device.  Since I have a KRX3, I feed the main RX
into input #1's right channel and the second receiver into the left channel.
I set the radio to give me main in both ears and second receiver in left ear
only. Since the device has two inputs, the second input is left unused and
becomes "input mute".  I don't use the radio's front panel headset jack for
headphones at all.

This device has four independent headphone level outputs with 1/4inch stereo
jacks on both the front panel and the back panel. Each channel has an
independent level control and a/b input switching.  I feed channel 1 out to
my station speakers (Yamaha self powered computer speakers) via the rear
panel jack. I feed Channel 2 to my headset via this channel's front jack. I
feed channel 3 to my audio recorder using the rear jack.  Channel 4 is
unused, but permanently wired and ready to use as an output for anything
with just a 1/4inch stereo plug.

A push button on each channel controls routing/muting to each individual
line level output feed.  When I need to mute my speakers, I press the
channel 1 button.  The green light goes out, and my speakers mute.  When I
don't need to record the output, I press the channel 3 button, the green
light goes out and the channel is muted.  If I don't want to feed my
headset, I press the channel 2 button and my headset mutes (but both the
speakers and the recorder feeds stay on if I have them selected to be on.
All four outputs can be controlled individually in any combination of on or
off state at the same time, speakers, headset, recorder and auxiliary audio
because each is individually switched.

The BEST thing about this is that each channel has its own level pot. This
means that I can have the recorder level set and vary both the speaker level
and the headset level INDEPENDENTLY. I don't run monitor very loud at all at
any time, so I don't get feedback with monitor on the speaker line when I
use speakers.  When I record I get BOTH my transmit audio AND the receiver
audio, and in SPLIT I get BOTH the TX frequency AND the receive frequency on
all recordings. An added feature is that the headset mixer has its own
BALANCE control, so I can vary the ratio of the second receiver in my left
ear only vs the level of the main receiver in BOTH ears. with one pot, yet
STILL have independent output level when I want it with the radio's
concentric AF level pot. So I can have both features on at the same time:
Not possible with just the radio, it offers either one OR the other (Balance
OR Independent receiver out on the concentric pots).

If you have a second op, you can use the fourth channel for their headset
and they then have their own individual level control separate from yours,
your speakers and your recorder AND THEY WILL HEAR YOUR VOICE as well as the
receiver output. This is nice for things like Field Day or Contesting with a
"partner".

It's really the best $40USD I have ever spent on my station.  BTW,
absolutely no RF feedback into this unit on any band using my KPA500 at full
power.  No notice of its wall wart power supply in my receiver either.

I believe this device will solve this need for the rig as is.  While it
would be nice to have this all built in to the radio, its currently not, and
I believe it wouldn't be that high on the priority list for development. But
this solution is both cost effective and offers additional functionality for
a very little capital outlay.

It works for me here.  It may work for you if you require this
functionality.

Re: [Elecraft] K2 panadapter bandwidth?

[Alan Bloom]

I don't believe this is a limitation of the K2.  The panadapter 
bandwidth is limited by the bandwidth of the sound card.


By the way, if the sound card's sample rate is 192 kHz, the panadapter 
bandwidth is actually somewhat less than that, limited by the 
anti-aliasing filter in the sound card, typically 170-180 kHz.  In 
contrast, the P3 bandwidth is flat out to 200 kHz.

Whether or not there's a 'need' to hear your own voice in the headphones
during transmit depends partly on the headphones. The better the
isolation of ambient sound they provide, the greater the attenuation of
the natural mouth-to-ear path. The two models of headphones I have both
provide excellent isolation of ambient sound. That's partly why I bought
them. (Originally for audio production work, not amateur radio.)
(Sennheiser HD25 and Beyerdynamic DT100.)

I find that so much isolation makes it difficult to speak. It feels as
though I've suddenly gone deaf.

The need to provide one's own voice in headphones, and keep it out of
any speakers in the same room, was recognised by radio broadcasters
decades ago. Pretty well every broadcast studio that's ever been built
caters for it.

I disagree that a 'slight phase shift' is distracting. A delay (of tens
of milliseconds or more) is distracting. Elecraft caters for this with
CONFIG:TXMON NOR or FAST. I use the latter and it sounds great.

I'm not sure quite what your evidence is for any 'majority belief'.
And if the need to keep microphone audio out of the speaker is not
common sense ... then what is? Does not every engineer learn this at his
mother's knee? My pointing this out is not a criticism of Elecraft. (If
anything, Elecraft is ahead of the game by providing voice sidetone at all.)

I am aware of the workarounds. I am also aware why they don't work for
me. You might not necessarily be aware of the latter, but thank you anyway.

Just to point out that I didn't write that.  I suspect something's gone

Re: [Elecraft] K3 does not fully powering down

[Dave Fugleberg]

Do you have anything connected to the 15 pin accessory jack on the K3?
I had the same symptom once last year, and tracked it down to a wiring
fault in a homebrew accessory cable.
If you do have something connected to that jack, try unplugging it
temporarily to see if the power down issue goes away.

Re: [Elecraft] K3S SSB TX monitor - feature request

[Martin Sole]

I'd like this functionality as well.

Phones either plugged in or not, RX audio only out of the speaker, RX 
audio and TX monitor in the phones.


Maybe a toggle in the settings for the monitor, speaker, phones or both. 
Monitor level remains as set.


Martin, HS0ZED

Re: [Elecraft] kx2 utility for linux on Raspberry Pi

[M. George]

This (ExaGear desktop) might be worth a try/look for those interested in
seeing if they can get the kx2util software to run on a Raspberry Pi.  Wine
as a Win32 emulator on it's own won't work with an ARM processor, but the
ExaGear desktop claims to bridge the gap to allow x86 code to execute with
Wine on an ARM processor..

Re: [Elecraft] kx2 utility for linux on Raspberry Pi

[AE0MM via Elecraft]

The Raspberry Pi line of computers use ARM-based CPUs. I'm not aware of an 
emulator that would allow x86 binaries to run on this platform. It is doubtful 
that anyone has been able to run the kx2util on this platform. (yet)

Has anyone successfully installed the kx2util software on raspbian for
the raspberry pi 3? The RPi-3 is a wonderful host for wsjtx and
fldigi. It controls the kx2 like a dream with only two short audio
cables to a $5 usb sound card and the included usb cable. I can then
control my kx2 via the RPi-3 using a virtual network computing window on
a remote desktop. This allows me to control the kx2 in the drafty, cold
shack from the comfort of my computer room upstairs (or anywhere else,
for that matter). The only drawback is getting kx2util installed so I
don't have to drag it upstairs for an upgrade. I would appreciate
detailed instructions if anyone has had success! Thanks - Murphy, KB3EOF

[Elecraft] K3 does not fully powering down

[Andrew UK]

Hi

K3 08206, failed to power down, pressing the power button turned off the K3
display and the normal clicks were heard, but the LCD light remained on.
pressing the power button again, would not bring the K3 on. Only removing
the 13.8V for a few seconds and powering on brings it back. However the K3
will still not turn off properly.

I have saved the config, updated the firmware, and reset the K3 by pressing
shift and powering on. I still have the same issue. I have not got anything
attached to the rear apart from the Linear amp key line, and that has been
removed.

It looks like a hardware fault, if someone can give me some guidance.

BR Andrew Lenton G8UUG

Re: [Elecraft] K3S SSB TX monitor - feature request

[Phil, GJ4CBQ]

Thank you Richard.

Having slept on it, I realised that my earlier retraction, as a result 
of Joe's posting, was somewhat hasty.  I blame tiredness.


It all hinges on Joe's statement:

"Richard admits that he does not need the speakers when he is using 
headphones/operating SSB"


Re-reading the posts this morning confirmed that you hadn't actually 
said that.


My posting yesterday evening was based on the understanding that you 
wanted to operate SSB using either speaker or phones.  Thanks for 
confirming this.  Prior to my original posting I tested CONFIG:SPRK+PH 
on my own K3 and confirmed that it didn't toggle the monitor function.


73,
Phil, GJ4CBQ.
