KX3 and Rocky 3.7

I am trying to get Rocky 3.7 to work with my KX3 similar to the display of the P3 and my K3. I have Rocky 3.7 running on my laptop computer and Windows 8. Rx I/Q is turned on in the menu of the KX3 and the cable supplied by Elecraft is running to my Creative model SB1100 USB sound adapter. My sound adapter is several years old so may not be the same as the new ones listed on the Internet.

Rocky Soundcard info
INPUT
Device 04 SBX-FiGo!
wFormatTag WAVE_FORMAT_PCM
nChannels 2
nSamplesPerSec: 48000
nAvgBytesPerSec: 19200
nBlockAlign: 4
wBitsPerSample: 16
cbSize: 0
wValidBitsPerSample: 0
dwChannelMask: 0
SubFormat: (00000000-0000-0000-0000-000000000000)

I did not include the OUTPUT data as I am not using the transmit part

My problem is I get two spikes for every signal. One is the correct one but an equal sized spike is shown on the opposite side of the screen. I do not think this is normal as I don't think other hams would want a display with that problem.

I have tried Rocky - View - Settings
Left/Right = I/Q
Left/Right = Q/I
Shift Right Channel Data by
-8,-7,-6,-5,-4,-3,-2,-1,0,+1,+2,+3,+4,+5,+6,+7,+8

I don't know what else to try and I do wonder if the
USB sound card uses stereo for the microphone but I have not been able to find that information on the Internet.

I would appreciate any help. I feel it is so close to working but not working right.

Re: KX3 and Rocky 3.7

Ken,

Are you getting a signal to the soundcard from both the I and Q
channels? What you are seeing is normal of only one channel is fed to
the soundcard.

In other words, check your cables. Plug in the left channel only into
the soundcard and see if you have a signal present, then do the same
with the right channel.

It may be a cabling problem, or your sound adapter may have only mono
input. Many external soundcards have mono input when the mic input is
selected, but may (or may not) when the Line In is selected - I/Q
decoding requires stereo soundcard input - if the input is mono, you
will see exactly the condition you report.

Re: KX3 and Rocky 3.7

Ken,

Getting the double signals very often is caused by not getting both I and Q
through the sound card into the computer.

Here is a handy sound card oscilloscope program that can be used to see if
you are getting stereo input to a sound card. Get a male to male 1/8 cable.
Plug one end into the sound card. Touch the ring and tip at the other end to
see if you get input on one channel or the other (but not both just touching
ring or tip).

Re: KX3 and Rocky 3.7

In reply to this post by Don Wilhelm-4

Hi Don

You answered and confirmed my suspicion. I suspect since I have a new Elecraft cable and the sound card only has the MIKE input that it is MONO. Do you know of a USB sound card that you will work? I would rather by something good that I know will work than spend money on something cheap that may not. I have got my use out of this sound card on digital ham programs.

Re: KX3 and Rocky 3.7

Ken,

Since the KX3 I/Q bandwidth is limited to something like 48kHz, you do
not need an exotic soundcard which will give you a 192 kHz span, most
external soundcards will do the job just fine.

The Creative X-Fi soundcard is available at a modest price, and will do
a 192 kHz span should you need it, but there may be other less costly
options that I am not aware of. The X-Fi can be modified with a couple
of added capacitors to reduce the noise level - Google for the mod
information.

The biggest consideration for use with the KX3 RX I/Q output is the
noise level rather than the bandwidth of the soundcard.

Re: KX3 and Rocky 3.7

Thanks Don for your help.

I still need someone to give me a model number for a USB Sound Card that will work as I only want to do this once. I have been on the internet but none of the sound cards tell me if the mic input is stereo. The Creative X-Fi was too generic for me to tell which model to buy so if I had the rest of the model information that still might be the answer.

73 and thanks for any information.

Re: KX3 and Rocky 3.7

I think he means this one:
http://us.store.creative.com/Creative-Sound-Blaster-XFi-Surround-5.1/M/B0044DEDCA.htm

As Don mentioned, you can add in some decoupling capacitors to make it a
bit quieter (after all, it is powered by the noisy USB).

Re: KX3 and Rocky 3.7

In reply to this post by Kenneth Christiansen

I remember seeing a post with a link showing a person with a KX3 using an iMic USB sound card. Furthermore, I recall him using an iPad, or similar, for the pan-adapter. He demo'd it and as I recall, there was very little latency to be seen. It was the best I had seen to date. I think the link was for YouTube.(maybe).

Yes, people have reported good results with the Griffin iMic. Mine certainly has stereo in, because I've used it to rip stereo LPs.

One small correction, iSDR is from Digital Confections not Pignology.

Ken,

Take a look at
http://us.store.creative.com/Creative-Sound-Blaster-XFi-Surround-5.1/M/B0044DEDCA.htm.
This is only one vendor and I am not endorsing it, just giving you a
picture of the soundcard I am recommending.

73,

I have been on the internet but none of the sound cards tell me if the mic input is stereo. The Creative X-Fi was too generic for me to tell which model to buy so if I had the rest of the model information that still might be the answer.

Re: "...KX3 I/Q bandwidth is limited to something like 48kHz..."

It is actually 192 kHz wide per the Owner's Manual, Page 26:
"Set the correct sampling rate...192kHz sampling will yield a display of about +/- 96 kHz."

My Sony VAIO VPCF121GX laptop has a very quiet 192 kHz internal soundcard, and it displays +/- 96 kHz hooked directly to the KX3. That is not to say that all that bandwidth is required, or even really needed. Most of the time I have it scaled down considerably. A 192 kHz soundcard will certainly cost more, so you may want to consider a 48 kHz card. They are the easiest to find, and won't break the bank.

I have a Griffin iMic (48 kHz), but I usually use it for fldigi's display, and keep Rocky running using the internal soundcard at the bottom of the screen as the bandscope. I just tried using the iMic with Rocky, and it works hooked directly to the KX3. Looks great on 2.5, 5, and 20 mhz WWV, but not as good on 10 and 15mhz. I just tried turning the preamp on, and it really helped on 10 and 15 mHz. I think I paid about $35 for this and it looks great! I really need to work with it at a time other than the middle of the night. It is after 1am right now and I am not thinking to well.

It is unfortunate that Rocky cannot read the KX3's frequency. It has one of the most useful frequency domain displays that I have seen. I said useful, not pretty. You can really see the signal, its bandwidth, and sidebands (key clicks on CW) on Rocky better than any other program I have tried. NaP3 is my second choice since its frequency domain display is almost as good, it is pretty, and reads the KX3 frequency, but I cannot get it to display properly on this wide screen laptop. It overwrites itself.

Way past my bedtime.

Ken,

Since the KX3 I/Q bandwidth is limited to something like 48kHz, you do
not need an exotic soundcard which will give you a 192 kHz span, most
external soundcards will do the job just fine.

Thanks for all the information and help

Thank-you Don W3FPR, Nick N3WG and Dick N0CE. I used your advice and ordered a Griffin iMac. I also ordered the iPad camera kit ic5331zm. I got a bonus going this way as I can use the pan-adaptor while I am camping on my iPad as well as at home on my Toshiba lap top. Thanks again I am please with your help and consider this thread closed.

Forgot to mention that Rocky "only" supports up to 96 kHz.
