Re: Rocky and soundcards

Alex,

?

Some feedback to you for the Creative Soundblaster Live 24 Bit External soundcard and Rocky 1.02.

?

?Version 1.02 will start with this card, however, ?the sound is quite muffled and sound is ?distorted.? Also, strangely enough, the program recognizes only one side of the cards input, or in other words, the left channel only.? Therefore, the automatic I Q function will not correct, nothing plots.? ?????This card will operate with the other Softrock programs and the I Q will correct out.?

?

Rocky works perfectly and sounds fine with the PC on-board card,? ?which is a Realtek AC97.? ??I would rather ?use the 24 bit card in order to use the 96 khz sample rate.

?

PC is Pentium 4, 2.4Ghz.? Windows XP.???? (ASIO4ALL disabled , (made no difference))

?

Thanks.? Hope this may help.

?

Re: Noise floor at -85dBm

Tony Parks
 

Hi Chris,

I have now built more than 90 of the v4.0 SoftRock40 receiver. All have worked properly, but some required additional effort. My number one problem was with my SMT soldering. Look very carefully for opens and solder bridges. Also check to make sure the center-tap voltage to T1 and pins 3 and 5 of U5 is at about 2.2 volts.

T1 has been a problem for a number of SoftRock builders. A quick test, but not a complete test of proper winding and mounting of T1, is to measure the resistance to circuit ground for the six vias where T1 in mounted. The primary vias, (two closest to board edge), should read zero ohms. The other four should read around 7.0 k ohms.

Hope you are able to get it working fairly quickly.

73,
Tony KB9YIG


A couple additional suggestions for what to check.
1) Check carefully the soldering around the SMT components.

Hi all
I am new to the group. I have finished my SoftRock40 today and
everything seemed to work fine. But then, after calibrating with an
external signal, the noise foor went up to -85dBm and stays there. So
only few strong singnals can be received at the antenna.
Any suggestions?

Rocky Problem

 

Can run the PowerSDR test wav files and both PowerSDR and SDRadio can pick the CW audio up OK. But Rocky gives an error message, "Input Device Does Not Support Selected Parameters". Is it possible to test Rocky just off of a wave file?

Hi, Chuck

Many thanks for your "sight": its the first "real" vision I get on Rocky***

Now I just think about having a QSO with a fellow using same SDR and seeing
simultaneously each other ;-))

-----------------------------------------
Citando Chuck Carpenter <w5usj@...>:

Here's what I see with this particular sound card.

Re: Noise floor at -85dBm

I can't answer your question specifically. But, I can tell you that the op amp and the is very quiet, it does not generate much noise. Thus, shorting the antenna where it is soldered to the input terminals will result in a very low audio output voltage from the softrocks audio amp gain stage.

But, it could be a software problem or a hardware problem in the softrock.

Before chasing after an RF problem in the softrock, I'd compare the baseline noise level (with the software running) between no connection to the sound card and the baseline with the softrock connected normally, except with the antenna terminals shorted together.

They should be the same, within 2 or 3 db.

In other words:

Start the software-

Hook the softrock up normally and short the antenna terminals and note the baseline noise level-

Next, disconnect the softrock from the sound card audio input plug so nothing is connected to the sound card at all and note the baseline noise level-

The two noise levels noted previously should be roughly the same, within a few DB.

If they aren't nearly equal, then something in the softrock has changed and you need to look at the softrock closer.

If the softrock is indicated as having a problem, you might start by checking the supply voltage to the IC's, it should be around 4.2 volts.

Hope this helps.

Hi Alex,

I'm still trying to get the Rocky code to run with this Santa Cruz sound
card since Rocky requires so much less CPU power when compared to the
PowerSDR (which runs fine) and I'd very much like to have a "portable"

It would be a fantastic thing if you shared this technology in some

have too much else to do. I would drop PortAudio completely and ASIO

drivers! ASIO is just too restrictive with its restrictions to one
device per system. I just finished virtual audio to connect to
applications without wires (I have been running MMSSTV and MMTTY without
wires for a few days). We have jack that does this beautifully on
Linux. Virtual Audio Cable, with the facilities just built into the
PowerSDR release about to come out, will do the job for it. But it
would be much lower latency and much less overhead if all of these
devices were opened in WDM-KS. I attempted for quite a while to get
MSVAD (WDM-KS) virtual sound cables (in the Windows DDK) to work before
giving up and using VAC and MME through PortAudio. I did not want to
do the latter because it costs $40. However, it is better than not
having the facility at all.

Hi Alberto,

As you know, Rocky talks directly to the WDM driver of the audio card. This
is the most promising but least explored method of audio streaming on the
Windows platform. AFAIK, no other SDR program currently uses this method
because WDM streaming is very poorly documented. There is some documentation
on the MS web site that explains how to write WDM drivers - but not how to
use them in applications.
However, WDM audio streaming is so attractive that someone has to find a way
of using it. This is exactly what I am trying to do. Due to lack of
documentation, this is to some degree a trial and error process, and I
depend heavily on the user feedback since the program works fine on all of
my own computers.

I have just uploaded v.1.02 of Rocky to
, this may have fixed the
problem that you described. Please try the new version and see if the
problem if now fixed.

Also, I have written a utility that displays properties of all WDM audio
devices on the system, this should help me to figure out what is going on on
the systems where Rocky is not working properly. If the device list in Rocky
is still blank, I will ask you and all other users who experience the same
problem to run the utility and send me the report that it generates. The
program is at .

Rocky and PowerSDR

[email protected]
 

Can't seem to get "Rocky" to work with this sound card (Santa Cruz) but
boy does it work with the "PowerSDR" software (chunking along at 50-60%
CPU). Hats off to you guys involved with bringing this little hardware
demo system out and to Gerald Youngblood and his team for some teriffic
software. The computer I'm using 1.7Ghz Celeron, didn't have the correct
B.Gates MDAC sw for installation and had a problem downloading over dial
up ....so I installed on another machine and moved the whole V1.4.4
FlexRadio Systems file over (with the SR-40 mods) and it works fine now.

Jean-Claude is right.

Let's see: Two lines for input (I/Q IF from radio) , two lines for output (I/Q for audio processing or single channel output). Sounds like full duplex to me!

Re: PowerSDR Error at Execution

 

Tony,

That is what I am running. I was just getting the software setup. I don't have my SoftRock 40 built yet. Have to do some prep for the Sunday School tomorrow morning, so will have to call it quits for now. Maybe will get to building it tomorrow afternoon.

I was kind of amazed PowerSDR works with my oddball sound card.

Hi Bill -
The documentation for starting out is not all that good for sure. Tuning is done with he mouse wheel (I hope you have one). Unfortunately tapping it changes the step size as well,and tuning at 10 KHz steps is not so useful. You have to keep tapping until you get back to a reasonable step. Most are not useful for the SR-40. You can also right click on the display to bring up cross hairs, then position them to a signal you want to tune to and left click and you are there. Sure is remarkable what can be done with a little hardware and software! Did you get the image to null out down into the noise? It should easily do so.
