Need Audio for SignaLonk from Sub-Rx on my K3

I am using the BNC connector for the Rx antenna and am receiving
primarily on the internal 6m band.

This is the first time I have tried it. Otherwise I have been working
many bands and using JT65 with no problems

I just now realised that my SignaLink soundcard in fact is NOT listening
to the Sub-Rx because I shut off the mast mounted Gaasfet and although
the sub-RX audio dropped way off, the JT65 program showed a steady,
unchanging noise level.

So how do I tell the K3 to put the audio from the Sub Rx and not the
main Rx?

Re: Need Audio for SignaLonk from Sub-Rx on my K3

Unless I am misunderstanding the question, you cannot. Not with a
SignaLink. The SignaLink is a mono input sound card (unless you re-wire
the plug to listen to the SubRX).

If you listen with headphones with the sub-receiver on, you will notice
that the subRX appears in the right ear while the mainRX appears in the
left. You can do the same thing (and I have) with a sound card that has
a stereo input.

To my knowledge, there are three sound card interfaces *designed* for
amateur radio:

1. Timewave Navigator (formerly by US Interface)
2. MixW RigExpert
3. MicroHam (various models)

At one time or another, I have looked at all three and debated which to
get. After much agonizing and gnashing of teeth, I decided to stick with
what I have for a few reasons:

1. I already had it (no money out-of-pocket)
2. The offerings only give me one thing I don't currently have
(front-panel Tx audio adjustment)
3. I didn't need rig control which all of the three have - it would be
wasted on me
4. They're relatively expensive ($250 - 300) even without the
*necessary* cable which costs ~ $50 (you *can* build this cable yourself)

I use an off-the-shelf external USB sound card. It is a Creative Labs
E-MU 0204 which I do not think is currently in production. You can look
it up to be certain. The previous model (0202) is also a good sound card
if you can find it. There are scads of internal sound cards available.
The beauty of the K3 is you do not need the audio isolation transformers
available in the SignaLink (or other sound card interface designed for
amateur radio); they're already built in.

This is not directed at you, but it is a preemptive statement to those
who will say you do not *need* the SignaLink: I apologize in advance for
"shouting," YOU NEED A SOUND CARD THAT IS DEDICATED TO AMATEUR RADIO AND
*SEPARATE* FROM YOUR MAIN SOUND. Just yesterday, on 20 m JT65, I heard
someone's WinXP "shutdown" sound over the air. You spent a couple of
thousand on the K3, please be kind enough to the rest of us to spend
another $100 or so and get a nice sound card. Yes, you'll hear all day
that the K3 has the ability to take audio directly from the sound card.
It is a wonderful feature. I use it. I use it with an amateur
radio-dedicated sound card only.

I wound up with the E-MU 0204 because I had experimented with kit-built
SDR a few years back (I built a SoftRock TXRX Ensemble II and a Genesis
G59/GPA10). The 0202 was already out of production, but the 0204 was
available. I bought it used for about $120. They're less expensive even
now. You do not have to go with my recommendation though. There are lots
of choices.

Again, I hope I didn't misunderstand the question and just flooded you
with un-needed information.

I do have an EMU-0404 though. I haven't used it in two years and it's
in a drawer. How would this help me? Are you saying it can split the
Sub-Rx audio out of the the two? ..Currently we take the SignaLink audio
out the rear line in Line out places.

I do realize the Sub-Rx audio is split when listening thru the headsets.

I am using the Sub-Rx because I see no other way to use a separate
receive line when I am using the internal 6m band. I have an Elecraft 6m
XV50 but am needing to split the Rx input on it and haven't gotten
around to it. It is wired to be able to take in Rx coax and have the Tx
o the other conn. ... O want Split lines to simplify using high-end
preamp w/o the usual possibility to kill said pre-amp if I screw up
timing. I am not going to debate the use of this method as I used it
extensively in the past in the 70's to 90's .

So, the gal is to find the near term solution for using internal audio
form the Sub-Rx.

I will re-install the EMU0404 and see how to get the audio out.

thanks for the idea.

Re: Need Audio for SignaLink from Sub-Rx on my K3

Bob,

In regards to RX audio only: if the 0404 has a *stereo* input, it will
listen to the MainRX on the left channel and the SubRX on the right
channel when the SubRX is activated. *If* what you're looking for is
being able to receive the audio from the SubRX, you will have to have a
stereo sound card. If the 0404 does that, you should be good.

If you're talking about anything else regarding the XV50, I'm not sure I
understand that part as I don't use one.

Sub rec audio is on right channel of all K3 audio outputs ( ring +sleeve). Make an adapter for SLUSB!

Not on the Line Out unless one sets Line Out= Phones and then the
AF gain controls the line out level.

Re: Need Audio for SignaLink from Sub-Rx on my K3

In reply to this post by W4JBB

Well gee ... when I ordered the K3, I got it "loaded" because I
correctly figured that eventually (A) I'd need some other non-usual
aspect for my weak signal stuff. And (B) that I would eventually figure
out how to read thee manual and also understand (eventually) what I just
read.

That said, I might have just discovered what the installed KXV3 module
could be used for.

I just plugged the Rx Down-Line into the KXV3 BNC "Rx Ant In".

I am now hearing signals from the antenna by selecting K3 front-panel
"RX ANT" . I see the waterfall of the JT65 program react to my switching
off the mast-mounted LNA. If that's the case, then the SignaLink is also
seeing the signal.

I however do not know if I have opened another can-of-worms by
connecting the Rx line to the KXV3 Rx-In connector.

Joel, I don't see a Stereo input on the EMU0404 box. I'd only used it a
few days when I once wanted to try receiving a VLF station form Sweden.
I guess Stereo wasn't needed. I wanted the high sampling rate of the
0404, at the time then.

No, unless you forget to select the TX antenna when you're not
using the LNA feed.

The EMU0404 has four inputs and four outputs - they can be configured
as four mono in/four mono out or two stereo in/two stereo out. In
either case you can connect input one to the tip of Line Out and input
two to the ring of Line Out and receive both channels at the same time
with the proper software (or configure WSJT to use input two for the
Sub RX).

Well, they do say opinions are like...

Shout all you want, but it is not imperative that you have a separate sound
card. The computer's integrated sound card can be "dedicated" to ham radio.
Keeping Windows sounds from playing through the radio is no different from not
transmitting outside the band. It's something that is supposed to be in our
skill set.

I have both a SignaLink and a Tascam US-100 (highly recommended by Jim Brown).
On RTTY, neither of these is either better, or worse, than the built-in card in
my laptop, and both require a USB port, something in short supply.

It's curious that we have this relatively tiny box of a radio that suffers from
poor ergonomics because of it and then we're supposed to festoon it with dongles
to make it play.

That's unfair and untrue ... there is a distinct disadvantage to
building every option under the sun into a transceiver. The biggest
is that all users pay more for the transceiver *and* the built-in
options (compare the panadapter in an FT-1200 to the P3 or SDR-IQ)
are far inferior to the "best of breed" that can often be had for
little more than the amortized cost of the built-in feature.

If one took your prescription, the K3 would only be available in one
configuration - with all options built-in at double the price of the
base unit.

Re: Need Audio for SignaLonk from Sub-Rx on my K3

Well now, *that* is untrue. If you think that is my "prescription" then so be
it, but that's not what I said. Nothing precludes additional features from
being options, which aren't necessary for modes one is not interested in.

That said, I don't think that a transceiver that is "supposed" to be
"state-of-the-art" should have to have an extra cost (and bulky) dongle hanging
off the back just to have acceptable receiver performance on ten and six meters,
just for example.

Re: Need Audio for SignaLonk from Sub-Rx on my K3

Well now, let's determine what is acceptable receiver performance. If
all I want is to work some openings on 10 and 6, the K3 can hold its on
with anyone in my experience. Certainly it out performs the IC-9100.
For "weak signal" work, a preamp is a welcome addition. I use ARR
P50VDG on 6m and ARR P144VDG on 2m mounted on transfer panels along with
appropriate RF amplifiers and a couple of multi-element beams.

Re: Need Audio for SignaLonk from Sub-Rx on my K3

In reply to this post by Bob KD7YZ

Bob,

You cannot tell the K3 to change it.

The Signalink is a mono soundcard and only listens to the left channel -
which is the connection to the tip of the jack. Even if the Signalink
cable has a stereo plug, there is nothing connected to the ring.

If you need to listen to the SubRX audio, you will have to use a
soundcard that is stereo.
If you use the internal computer soundcard, be sure to turn off Windows
sounds.

If you want to use the Signalink, you would have to make an adapter for
the Signalink audio input so that the audio is taken from either the tip
(normal) or the ring connection (SubRX) - a manual switch would be in
order to select either one.

Bob,

Before attempting to use the EMU-0404, check your application. If it
cannot select between the left and right channel inputs, then you may as
well continue using the Signalink and switch the channels manually as I
suggested in my prior email.
