Signalink and K3

Hello

I am to buy a signalink and want to know which is the best way to connect it
to the K3 so I can order the right cables

Thanks!

Re: Signalink and K3

if you plan to use a signalink you order it with the K3 Cables.
SignaLink USB p/n SLUSBK3

Keep in mind that you really don't need a signal link with the K3
any good sound card will work as the K3 has isolation built in. all
you need is cables with 3.5mm plugs on the ends to plug into K3 line
in and out.

the advantage of the signallink is that it has real level pots and its
becomes a second sound card.

That's not the reason for using a better sound card. Indeed, NO
transformers are needed if the equipment is properly bonded together.
The reason for using a better sound card is for better A/D converters
and a quieter signal chain, which results in MUCH better decoding of
digital signals.

The SignalLink has several serious problems, and is NOT a good solution.
Further, it's a single channel box. See the pdf link I posted for Jorge.

Don't waste your money on it, Jorge. One of the Tascam units is far
superior, and about the same cost. http://k9yc.com/USB_Interfaces.pdf

Re: Signalink and K3

In reply to this post by Jorge Diez - CX6VM-2

I ran JT65 EME for a long time using the computer sound card and had mysterious periods of no decodes even on signals I could easily see on the waterfall. This occurred even though I had carefully calibrated the clock rates. Then I bought a Tascam 122 mk II external sound card and the vast majority of missed decodes vanished. Plus you get two nice, big knobs to turn. Just make sure you install the latest firmware AND driver from the Tascam website--mine would not even work at all out of the box until I did this.

Well worth the money, and as Jim says, you don't need the interface.

Re: Signalink and K3

In reply to this post by Jorge Diez - CX6VM-2

Jim and Jorge

I was merely answering Jorge's question. perhaps I should have
given better advice and steered Jorge away from signal link as you
did. I do agree that a signalink or similar is far from ideal and
even less so on the K3 as it would be doubling up on the isolation
transformers that are already part of the KIO3 board in the K3
possibly leading to additional loss in quality.

so to Jorge Diez here is my revised answer!

Forget the signal link, Rigblaster or other commercial fit all rigs
type solution. get a good high quality sound adapter like the tascam
from B&H as stated in Jims article you will be way better off this
way for decoding and encoding for psk, rtty SSTV and more important
JTXX, WSPR etc. than the users of the mediocre commercial "fit all
rigs" solutions and at a better price. I think setting up with this
would actually be simpler than mucking about with the jumpers etc of
the signalink there is no need for a PTT connection either as most
digial software will handle this via command or vox. keep it
available for a foot switch.

I am using an old M-Audio mobile pre USB that was retired from field
recording sound effects. its perfect for this use. I believe it was
Jim's article some years ago that lead me this way and I'm glad I did.

PS B&H is a great source for this kind of stuff I use them for most
of my audio and photo needs.

Re: Signalink and K3

In reply to this post by Jorge Diez - CX6VM-2

At the risk of being repetitive:

The K3 with K103 module has both audio line in/out interfaces and
RS232 interface for running computer soundcard sw. The Signalink is
not required and is probably not up to par with just using a *good* soundcard.

My first "soundcard" sw mode was psk-31 back when no body made
interfaces, so I made my own (circa 1998).
Obviously using the internal computer soundcard spkr and mic
connections to connect to my FT-847 (which nicely provided an audio
and PTT DATA port). My interface had 600-ohm 1:1 transformers and a
NPN transistor for keying the radio from the DTR or RTS in the RS232 cable.
http://www.kl7uw.com/Radio-Computer%20IF.jpg

It was not long and several companies jumped into the soundcard
interface business.

On 2003 a new digital mode for eme was introduced (JT44) and I jumped
on installing and running it. It morphed into JT65 in a couple years
and about 3-4 years ago MAP65 emerged. I have run them all.
http://www.kl7uw.com/MAP65.htm

I was thrilled to find that Elecraft had the forethought to include
the necessary interfaces for running soundcard digital modes without
any extra "stuff".

Now some other things I am involved in (I bought a LP-Pan) required
better soundcard modems so I bought the (then) recommended emu-0202
external soundcard and later a four channel M-Audio Delta44. They
run faster A/D and could support watching up to 190 KHz of spectrum
with panadaptor sw (and WSJT sw). I think they also exhibit better linearity.

Ahah! This is one of the characteristics that appear to help sw
programs like JT65 "work better"!

I have not studied recent soundcard offerings, but I am sure there
some experts on that topic on this list who can assist anyone looking
to *upgrade*. One thing to consider is OS compatibility
(drivers). The other is physical interface (USB, RS232, etc.). My
Delta44 has pci mounted pcb; you will be custom-building a computer
to have a pci-buss these days).

So *bottom line* the K3 does not need a Signalink.

That's what I'm trying to figure out. What are those problems? Is
there any reason it wouldn't work fine with Winmore modulation format on
WinLink?

Re: Signalink and K3

> That's what I'm trying to figure out. What are those problems?

Probably the best place to start for issues with Signalink is:
http://www.frenning.dk/OZ1PIF_HOMEPAGE/SignaLinkUSB-mods.html

In general (at least in the case of the original units):

1) the Signalink design lacks a regulator for the V/2 bus that
provides both a reference for the CODEC and the audio op-amps.
The manufacturer of the CODEC (TI) calls for the V/2 regulator
in the product data sheet and extensive audio design experience
recommends regulation of the V/2 voltage in op amp circuits.

2) the Signalink is USB powered. However, the USB power is not
adequately filtered or decoupled placing digital noise from
the computer on the Signalink power bus (and coupling into
both transmit and receive signals).

3) the Signalink uses low quality audio isolation transformers
which create significant "tilt" across the passband

4) the Signalink internal PTT circuits require the CODEC output
be run wide open for reliable PTT action. At lower voltages
(and without regulation), the CODEC generates significant
distortion at maximum output.

5) the Signalink internal power distribution lacks proper by-pass
and decoupling resulting in both noise and audio crosstalk
distribution via the power circuits.

6) In spite of the use of transformers, the unit still appears
to be susceptible to a "pin 1 problem" and RF feedback -
probably due to a number of the previous problems and most
likely due to the lack of proper filtering/decoupling of the
USB power source.

> There's a fix in a recent QST (this summer) for one of them. W4TV
> identified another one.

The referenced fix (August, Hints & Kinks) addresses the lack of
regulation an noise to the Op Amps but not many of the other issues.

Ed, I presume you're running some I/Q processing with the LP-PAN. Are you
doing that while running a computer based digital mode? Are you using a
separate audio interface for the RX & TX audio in those modes? Is it
possible to have to sound cards connected and running at the same time?

Re: Signalink and K3

Art,

Yes, multiple soundcards are possible, and each can be dedicated to
different purposes (i.e. one for panadapter display, one for soundcard
data modes, and another for Windows sounds). You will have to 'monkey'
with the default soundcard for Windows each time you add one, because
Windows always automatically sets the latest added card as the default.
You select the soundcard to be used in the individual application.

The 'problem' is "how do you get all applications to talk to the
transceiver through one serial port" when each of those applications
want to have a dedicated port to control the rig.
Larry Phipps N8LP has created LP-Bridge which creates virtual ports
that can be used to connect those other applications and send their
command/responses through to the rig over the real serial port.
There are other virtual port applications that do the same thing, but
LP-Bridge was initially created for the K3 and works quite well with it
- LP-Bridge presents an interface to the various applications that look
like a K3 and buffers some information so as to reduce the polling and
responses from the K3. There is an alternate LP-Bridge2 that works with
other transceivers.
Additional information can be had on the LP-Pan Yahoo Group. Larry is
quite approachable and helpful with setup questions posted on that group
reflector.

Ed may chime in with more detail.

Yes, LP bridge (LPB2) is a really cool tool for the Windows user. I use it on Win 8.1 under VMware Fusion on an iMac. It allows me to run NAP3 and Log4OM at the same time with my KX3. Be aware, however, that is is a Windows-only program; there is no Mac or Linux version out there, as far as I know.

You will have to 'monkey' with the default soundcard for Windows each time you add one, because Windows always automatically sets the latest added card as the default. You select the soundcard to be used in the individual application.

Re: Signalink and K3

In reply to this post by ve3dvy

Rather than buying a Signal Link, If one wants an external sound card of good quality (and stereo), I would think the Asus Xonar U7 USB sound card ($80 or so) would be a good choice. For PTT I believe you can use a RS-232 cable to the K3 and set DTS or RTS line to PTT. Have not tried this yet, but I think it would work fine with Winmore.

Jim and Jorge

I was merely answering Jorge's question. perhaps I should have
given better advice and steered Jorge away from signal link as you
did. I do agree that a signalink or similar is far from ideal and
even less so on the K3 as it would be doubling up on the isolation
transformers that are already part of the KIO3 board in the K3
possibly leading to additional loss in quality.

so to Jorge Diez here is my revised answer!

Forget the signal link, Rigblaster or other commercial fit all rigs
type solution. get a good high quality sound adapter like the tascam
from B&H as stated in Jims article you will be way better off this
way for decoding and encoding for psk, rtty SSTV and more important
JTXX, WSPR etc. than the users of the mediocre commercial "fit all
rigs" solutions and at a better price. I think setting up with this
would actually be simpler than mucking about with the jumpers etc of
the signalink there is no need for a PTT connection either as most
digial software will handle this via command or vox. keep it
available for a foot switch.

I am using an old M-Audio mobile pre USB that was retired from field
recording sound effects. its perfect for this use. I believe it was
Jim's article some years ago that lead me this way and I'm glad I did.

PS B&H is a great source for this kind of stuff I use them for most
of my audio and photo needs.

Re: Signalink and K3

In reply to this post by Jorge Diez - CX6VM-2

Art,

First off, by mentioning the use of the LP-Pan in the response to not
needing to use a Signalink, I probably gave too much info (muddied the water).

I bought the emu-0202 to run with my LP-Pan since it was recommended
(simple answer).

Now to address your question. Yes, I needed to use a SDR (I chose
the LP-Pan) to produce a IQ baseband output for the software I wanted
to run (eg. MAP65). For this application I am not using the 15-KHz
DSP of the K3 at all so not using the audio lines to the
computer. The reason is that I needed faster A/D for wideband
spectrum (90-KHz) display and the audio output of the K3 is limited
to 4-KHz. I do use the RS232 I/F for keying the K3 Tx with the DTR line.

However, I can run JT65 using the 4-KHz audio line-out from the
K3. For that all that is needed is a soundcard. I use my emu-0202
because my internal soundcard "crapped out"; I disabled it so I could
use the external soundcard. JT65 can display up to 4-KHz.

I am not the person to answer running multiple simultaneous soundcard
applications because it don't. But I suspect there is a way.

Hope that clarifies things??

73, Ed

Ed, I presume you're running some I/Q processing with the LP-PAN. Are you
doing that while running a computer based digital mode? Are you using a
separate audio interface for the RX & TX audio in those modes? Is it
possible to have to sound cards connected and running at the same time?

Re: Signalink and K3 (you do not need need a Signal Link)

In reply to this post by Jim Brown-10

Jorge,
Interesting enough, at a recent club meeting, the presentation was on using the SignalLink as an interface between your radio and computer to operate Winmore using RMS Express. Until reading all the threads the last couple of days, I was contemplating purchasing a SignalLink; however, last night I tried hooking my K3 directly to my computer.
All I did was connect the line out on the K3 to the mic in on the computer (using a stereo cable) and the line in on the K3 to the headphone jack on the computer. Only thing missing was a way to key the K3. This is easily solved by using the RS-232 port on the K3; hook the K3 RS-232 port to your computer (since my computer does not have a RS-232 port, I used a RS-232 to USB dongle). First go to the config menu in the K3 and find "PTT -- Key"; set either DTS or RTS above "PTT" to on. Now open RMS express; in the setup there is a "PTT Port (optional) setup. Just selected the correct serial port (found in control panel/device manager), baud rate you selected in the K3 config menu, and use either RTS or DTS for keying (the same as you set in the K3 config "PTT --Key" setting).
Fired everything up, set the Line out gain (I found 3 to work fine), then go to menu and select "Line In" and set the mic gain to an appropriate level (4 worked for me); that was it, and I was able to establish Winmor connections on 80 and 40 meters.

Don't waste your money on it, Jorge. One of the Tascam units is far
superior, and about the same cost. http://k9yc.com/USB_Interfaces.pdf
