Re: [Elecraft] K3 and SDR-IQ and CW Skimmer

[Don Wilhelm]

Ignacy,

I know nothing about the display capabilities of SDR-IQ, so the only 
thing I can say is that the actual input frequency of SDR-IQ must be the 
same as the IF frequency of the K3 - 8215kHz.

If not, it there any way of configuring SDR-IQ to follow band changes with
K3?

Re: [Elecraft] KDSP2 discontinued??

[Don Wilhelm]

Mike,

The DSP-X board is no longer obtainable, so the kit had to be discontinued.

Re: [Elecraft] K3S Sound Board upgrade for K3

[Vic Rosenthal]

I had heard that it only affected the speaker. But a friend that has both a K3 
and a K3S says the audio is better on the S, and he is a former sound man. 
What's known about this?

[Elecraft] IMD and CW (was: Re: K3s - 80W on 160 - Resolved)

[Vic Rosenthal]

I didn't exactly do this, but I did investigate the effects of distortion on CW 
signals. I disconnected my P3 from the K3 and set the IF to 7 MHz. so it would 
act like a standalone spectrum analyzer. 
I was interested in whether a class-C amplifier I had built would sharpen the 
keying enough to create noticeable clicks. The amplifier used minimal fixed 
bias to allow a small amount of resting plate current in transmit mode, with 
full class-C operating bias provided by a grid resistor. 
I noted a broadening of the base of the signal on the P3, indicating that the 
signal was not as clean as the K3 alone.  But listening with another receiver 
on either side of the S9+30 dB signal didn't reveal audible clicks. I also 
asked other operators to listen and there were no reports of clicks.
I am sure that attempting to use that amplifier (a pair of 813s) on SSB would 
have gotten me ridden out of town on a rail!

[Elecraft] K3S Sound Board upgrade for K3

[Guy Olinger K2AV]

Whatever happened to distributing the K3S sound board and its various
improvements for the K3. That's been rumored forever it seems. We have the
various other improvements, synthesizers, new preamp, etc. But not the new
sound board.

Is that project still alive, will it actually happen? If so, a time frame,
is anyone in the splendid engineering department actually working on it?

Or have you guys gone all-hands on some huge new splendid offering we
haven't heard about yet.  ????

Just wishing and wondering.

[Elecraft] P3 "USB DEVICE REMOVED"

[Jean-François Ménard]

Hi,

I’m using my USB keyboard with the P3+SVGAboard. The keyboard works great until 
I power off the P3 then back on. I always have a message on the external VGA 
display « USB DEVICE REMOVED » and the keyboard doest not work until I unplug 
the keyboard and plug it back again.

When I turn on the P3, I always see the keyboard usual init flashing green led. 
When in the terminal mode, I cannot see the K until I unplug then plug again 
the keyboard.

Any idea ???

Regards,

Re: [Elecraft] K3 and SDR-IQ and CW Skimmer

[Wes Stewart]

I don't use skimmer so can't begin to comment on that.  But I do use an SDR-IQ 
with SpectraVue on my K3 and/or K3S i-f output(s).  The SDR-IQ follows the K3s 
perfectly and conversely, you can point-and-click the screen in SpectraVue and 
tune the K3.  You can also tune the K3 with the mouse wheel.


Since my K3 needs to talk to my logging programs too, I use LP-Bridge to 
facilitate that. I've recently become interested in 160 DXing and the waterfall 
display is invaluable in showing signals that I would probably miss when 
manually tuning the band.


If you want more setup info contact me off list.  Elecraft wants to sell P3s.

Bill,

There are no good news stories on using RemoteRig over satellite. A couple
of people have been on the RemoteRig Forum where things like this are
discussed at http://www.remoterig.com/forum/index.php and had tried in vain
to get it to work.

As Joe wrote, the latency is too high to make it work. To put it more in
numbers, the speed of light is (only) 300,000 km/s and the geosynchronous
satellites are in orbit at 40,000 km. Therefore, for the double round trip
that is necessary for the packets, you have a trip of 160,000 km. This gives
you a latency of 533 ms. Then you need to add on the normal ground latency
that comes on top of this in the 200 ms range, giving you a delay of about
three-quarters of one second! Things get difficult for SSB once you hit
about 200 ms, so this just will not work due to physics.

Re: [Elecraft] K3 remote over satellite internet?

[Joe Subich, W4TV]

The latency (delay) through the satellite will probably be a killer.
IIRC, ping times through a satellite link are > 500 ms (120 ms up,
120 ms down *times two* plus any time in the network on each end).

The question becomes can you handle ~1/2 second delay in control
response and deal with audio that is delayed by ~1/4 second each
way?

Re: [Elecraft] K3 remote over satellite internet?

[Fred Jensen]

I can come close.  I currently operate W7RN remotely using our AT&T 
Uverse Internet.  It's 45 Mbps from the street to the router, and the 
computer and Remoterig box run in the 18-20 Mbps down and half that up.  
Ping time to the station is in the 40-45 ms range.  It works fine [well 
... nearly all the time, sometimes the I'net loses packets but that's 
rare].  W7RN uses Teamviewer to access the PC that runs all the station 
automation.  Teamviewer exhibits some increased latency, annoying but 
certainly usable, but that's not the remote radio connection.


I have never operated a radio remotely over a satellite link.  I have 
used such links [HughesNet] for computer-computer work.  For file 
transfer, web downloads, and even interaction with web sites [Amazon, 
PayPal, etc], it is acceptable.  For remote control of a distant 
computer, it is nearly, if not completely, unusable. The space delay is 
only about 27 ms or so, but there the net latency was in the 2-4 sec 
range so there must be additional delays involved.


These experiences suggest, to me at least, that the latency of satellite 
links would make remote operation of a radio very difficult if not 
impossible.


FWIW: We live in a suburban neighborhood with lots of wifi on the 
scanner.  I put our Uverse wifi on the most occupied channel once [6] 
just to see the effect.  The speed seen by the Remoterig box dropped to 
about 1.5 Mbps.  Everything continued to work just fine. I've been told 
that it will work with 500 - 600 Kbps.

It would be interesting to see how much IMD it takes to significantly

I'd expect the effect to be small, compared to that on an SSB signal for

[Elecraft] K3 and SDR-IQ and CW Skimmer

[Ignacy]

I am trying to set up CW Skimmer with SDR-IQ and K3 so that SDR-IQ is
connected to IF OUT and follows K3's frequency. Is this doable?

If not, it there any way of configuring SDR-IQ to follow band changes with
K3?

Ignacy, NO9E

Re: [Elecraft] ERR KEY

My first guess is that either DTR or RTS is being asserted by WSJT and 
you have it configured in your K3 for PTT.  CONFIG --> PTT-KEY --> 
OFF-OFF will do it if that's the case.  Happened to me.

Does anyone know of any physically small audio interfaces for the KX3?


I'm looking for something like the SignalLink USB (built in audio 
codec is required) but less volume.



I've assembled a great mini digital station with my KX3 and a portable 
RaspberryPi, but the size of the SignalLink USB is just too much for 
what it does.



Recreated with modern technology it shouldn't be any larger than a 
pack of Wrigleys gum! The Audio Transformers should be the limiting 
factor in the design.



Has any company made a similar interface where size was a primary concern?


Thanks all!

Bill,

IMD also affects CW. What we call CW is not "continuous wave," it is a 
continuous wave that is 100% modulated by a rectangular wave. That 
rectangular wave is rich in harmonics, and excites IMD. We hear it as 
clicks. This can be clearly seen on slides 8-16 of 
http://k9yc.com/P3_Spectrum_Measurements.pdf Slides 8, 9,and11 show the 
spectrum of a real "continuous wave" -- that is, a steady, unkeyed 
carrier. Slides 14-16 show the spectrum of dits at about 30 wpm. The 
difference is the keying sidebands, and those humps down below -50 dBC 
are IMD.

"A thicker wire 
would certainly require less voltage than 
14.6 and that's what I am going to look 
into."

Another reason to run higher voltage is improved IMD performance on SSB
transmit.  Lots of info available from previous threads.  I've been running
14.5 at the K3 terminals on multiple units for over 5 years with no
problems.
