      EnsembleRXTX - a most perplexing problem

      Posted by: "w1srb" w1srb@...   w1srb

      Tue Oct 4, 2011 12:49 pm (PDT)



      Summary; only one channel and no image rejection.

      I finished building my Ensemble RXTX a few months ago and have just gotten around to the final transmitter tests, which required a computer with more processing power than the netbook I was using (the transmitter works fine). I think the receive worked when I tested the receiver section some months ago but it's not now. I'm using an E-MU 0202 sound card - the right channel LED doesn't light at all with the RXTX running, no matter what the E-MU volume is set at. When interchanging the plugs on the E-MU, still no right channel, which you would think indicates that the problem is in the E-MU. However, when the same cable is plugged into a portable CD player, both channels on the E-MU work fine (i.e., the LEDs for both channels light at the appropriate volume setting). Furthermore, when I plug a softrock lite into the E-MU that I use as a pandapter with my K2, it also works just fine with good image rejection using Rocky (which I also used for the RXTX). Changing the E-MU ground to floating has no effect and I've even made a new cable and that didn't change anything - So, I'm most perplexed... any suggestions as the what the problem may be?

      Thanks.

      From 9Ħ1AV
      Just for information, when I started with my license in 1967 (is it that long? my my how time flies) I used a B28 or as it is also known a CR100 hotted up with various mods.
       
      Above 7 MĦz, I used an R208 which tuned from 10 MĦz to 60MĦz in three bands. It had a 2 MHz IF so I took an output from the detector IF tranfomer at 2 MHz and fed it into the B28 which was used as a tunable IF.
       
      This was for two reasons. Notwithstanding the very slow motion drive tuning was very fast on the B28 on the last band which covered 11 MĦz to 30 MĦz and stability was not that good.
       
      Tuning the 14 MĦz, 21 MĦz and 28MĦz which were the other available ĦF bands at the time on this setup was very fine with the B28 tuning being a sort of very fine bandspread, the main tuning being done on the R208. The R208 was deaf by itself but the combination worked very fine. This setup was also used with a 2 metre converter in front of the R208 resultign in a triple conversion overall receiver system as we had to do with we had available at the time. This was before I got an AR88D. All these receivers are still in good working conditions and in fact presently I am using the B28 to operate on 500 kĦz until I make a receiver ro a converter.
       
      So yes, you could use another receiver tuned to the TS850 IF so that you will be using your other receiver as a tunable IF and will hear signals in the IF passband of the TS850.
       
      Hope this explanation is clear enough.

      If you have a scope that goes to at least 10mhz(most do these days) you will see the signals. There will be a lot of signals jammed together if your using a antenna because of the wide band width. If you use a signal generator it will me a more usable view. It will be enough to tell you if your seeing the output of the mixer. I use a scope on the output of my BPF on my R390. It is 455kc so just about any scope will do that.
      Another RX will do the same thing. What ever is easier for you to try.

      RX Ensemble II is not working HELP!!!

      Posted by: "jacob" kd7vea@...   kd7vea

      Tue Oct 4, 2011 6:05 pm (PDT)



      Hello everyone. I am new to the group, and SDR all together. I purchased a RX Ensemble II a couple of weeks ago, and I have been working on it for the last week or so. I finally have it complete, but it is not working. it is doing some weird things. I plug in my 12 volt supply, and then the USB, and the audio cable. a box pops up that says there is an unrecognized USB device. I have installed the driver,and if I go into my device manager and uninstall, and reinstall the device, and then "upgrade" (reinstall) the driver, unplug the usb,and plug it back in, most of the time, it will recognize the device. I am running the most current version of HDSDR, and I have installed the Certificate for the driver. I have installed CFGSR version 2.3 into the same directory as HDSDR. everything is up and running, but all I hear is clicking, maybe 4 clicks per second I am receiving no signals at all. everything looks like it works, but it does not. I am running windows 7. I was also wondering, at the testing stage during the build were you use a receiver to hear the oscillator, should that be a full quieting signal? I was using a handheld scanner, and if I held the antenna close to the board, I was hearing clicking (maybe 4 clicks per second). I hope someone can point me in the right direction. thanks

      Did you test the torroids for continuity? It's easy to get the primaries and secondary's mixed up when installing them.
      Also the enamel on the windings can cause some bad solder joints if not properly removed. Thats been a common problem.
      As far as hearing the local oscillator with the scanner it should be a strong signal.
      Check for a loose connection or bad solder joint around the att tiny and usb components.
      I would use the build and test notes on Robbie's web site and go thru all the stages again. http://www.wb5rvz. com/sdr/. There are also links in his web site that take you to good sites with discriptive information on the problems you are discribing.

      I bet you will get it working.

      Thanks for the reply. I have been using wb5rvz.com for the entire build. I did all of the tests to show continuity on the toroids, and they checked out during the build. if I start from the begaining and do all of the tests, are they going to give me the same readings with the completed board? one thing that I was wondering about is the SI570. there are three connections on each side (north and south if laying the board lengthwise in front of you) but then on the ends where it has the two connections, there are actually three traces showing on the sides. right now, I only have 8 pins soldered to the board, should it be 12 pins soldered to the board? thanks for the help.

      Hi,
      Si570 has 8 pins and you need to solder those 8 pins only.
      Connect power to the Rx, connect the USB cable between the computer and RX,
      run CFGSR.exe and check the 'General' and 'Test' tabs
      to ensure proper working of the oscillator.
      All the best,
      rk

      Jake,

      This is a rather crude test so difficult to specify what strength you may
      find. The important thing is to hear the signal and verify it moves
      frequency. Is the clicking associated with this signal?

      hello everybody purchased the ensemble from tony assembled and tested as I could not wind toroids and do surface mount with one hand. tearing my hair out trying to get it to work downloaded the si570 usb driver, rocky 3.7 hooked it up. pc talked to the sdr but no signals. well I felt like a fool when I realized what I done, when hooking up surround sound, eq's and such you always take the output and feed it to the next input. well when I seen lineout I automatically pluged it into line in on the sound card anyway you see where I'm going here READ THE DIRECTIONS well now that I have it all up and operating I would like a nice enclosure for it
      I seen one online but did not bookmark the site anyone know where to get one ready made for the ensemble rx/tx? Now to build a 40 watt mosfet amp
      something I can do with a little ingenuity.

      Hoping this will work with the Softrock Ensemble II receiver:

      192 Khz sampling. About $20 after I applied a gift card (48.99 without). Seems like a decent price, but will it work?

      Hi ,

      I'm using this card with very good results in my WebSDR servers (linux
      based).
      In my opinion is one of the best options for SDR in terms of
      price/quality, much better than any Creative card I have (including
      EMU-0202).
      In Windows it works like a charm with ASIO drivers at 192KHz/24bit.

      Hope this help.
