ensemble rx ii has a problem


 

what did I do wrong on my softrock ensemble rx II? I'm using the cheap
little syba (aud20101) usb sound card and this is what I get when I try to
use it as my input.

I've not seen anything like this.

What is it like without anything plugged in?
Have you tried mixer controls? Stereo Mix?
What PSU?
Have you any other sound? On-board?

I'd guess it's working at only 48KHz. And a lot of these were mic input mono but you would see signals.
(The Ensemble is only designed to go down to 3.5MHz although it will receive lower with a reasonable antenna.)

One other note, it's the same display from 80M - 10M


 

I have seen this display. It is quite dramatic, startling even when you expect to see the normal display. Unfortunately, I can not remember exactly what the problem was in my case but I think what returned my Ensemble II set up to normal function was to unplug either the rx or the soundcard USB and plug it in again. (Do you have the USB drivers for both the rx and the soundcard installed?)
There is another, less dramatic but still abnormal, display that sometimes appears for me where the fix is to change the frequency, even 10 Hz.


 

Re. my USB comment. Is the soundcard working OK for other apps, like playing music files,? if so my question re. USB driver is probably not relevant. Is the rx frequency control (which uses the USB) working when you use the "SoftRock Configuration Tool"? The latter should show that the Si570 is connected and succeed in changing the frequency. If that is OK and the display is still not showing the band signals, then I would guess that the USB for the rx is OK (but that USB control dll file has to be in the HDSDR directory as well as in the CFSGR exe directory I think). The cabling from the rx to the soundcard line input (not line output in spite of what it says on the rx) might be worth looking into also. My setup is quite sensitive to the sound cable quality and length. I am new to the SoftRock world myself, so hopefully one of the experts will have the solution for you.


 

I will check on the operations of the USB card, I am leaning towards a cable problem though

Tried a different 3.5mm - 3.5mm cable - just the same.
I get the same thing from the line in on the laptop Dell d630 and the usb sound card.
I'm starting to think it's a PSU problem - cheap multi-voltage walmart
Any other thoughts from the experts?

I have not had good luck at all with wall wart power supplies unless they are transformers. The lightweight switching supplies cause hum and noise both on the receive display and on the transmit signal. I even purged them from my entire shack. Try the rig on a 12V battery and see if that cures the problem.

First thing to try in _any_ weird problem. It's quick, easy, and has a
decent success rate. PS noise can find its way into weird places and
cause some truly odd symptoms.

Adulthood isn't an award they'll give you for being a good child. You
can waste... years, trying to get someone to give that respect to you,
as though it were a sort of promotion or raise in pay. If only you do
enough, if only you are good enough. No. You have to just... take
it. Give it to yourself, I suppose. Say, I'm sorry you feel like that
and walk away. But that's hard.

2 6v lantern batteries in series, no change :(

12V connected


 

12v not connected, but moving the LO around doesn't change the display below (tuning does nothing)


 

The HDSDR display shows a very wide bandwidth, with big signal bars at +- 30 kHz. If you set the soundcard to 48 kHz with HDSDR and make the HDSDR display show only +- 24 kHz, what does the display then look like? Are you getting any real RF signals thru the rx?
Interesting puzzle.


 

Now I have a question. The email version of Kevin's posts that I receive have screen captures of his HDSDR display, but the posts I see on Yahoo Groups only have the text, no images. How do I get the Yahoo posts to show the images?

You should see a flat line with no 12V.
Use HDSDR at 48KHz, what do you see? Please confirm that you see nothing if the audio lead is removed.
Otherwise, presumably you built this Ensemble?
Did all the checks go well?

I have to open Kevin's email in my browser....
And I too cannot see the pictures on the Yahoo web interface.

Maybe it would be better if Kevin posted pictures as attachments?

Something is not compatible with Yahoo (and my email client)

Ditto, the image box is empty, I have to re open the mail in Firefox
to see the attached image.

I see all the screen shots in my email client (Apple Mail). I very rarely go to the web group page

without 12v I have a (reasonably) flat line @ 48khz - with the spike at the LO frequency
My internal card does 192/24
My external card does 96/24

Input : Softrock Si570

Input channel mode for RX: I/Q
Output channel mode for RX: AF to both channels

Swap I and Q is checked (I swapped the jumpers during build as recommended)

There is no guarantee that your sound systems will work higher than 48K without some configuration in their panels. Sometimes this can be tricky, so leave it at 48K for now.
So, do you now see signals when you connect a good antenna?
Assuming you have checked the basic sound mixer controls for correct input selection and gain.
