    Funny how those things can jump so far. I had one jump and spent 2 hours on the floor searching. The wife finally found it. Whew. Got mine up and running.

      Hi.
      I'm new to SDR and it's my first Softrock (I've an RXTX Ensemble waiting, but I've prefered to begin with a less complicated kit).

      I was slow on built and I'm not easy with toroid !
      Everything went well until I missed in the QSD step with strange voltages observed during test. Typically, A-R11 (voltage divider) show 120mV instead of 2.12V previously.I finally decided to undo the step, unsoldering U2 (with a special tool) wasn't too difficult and R11 voltage become 820mV, better but not good. I continued with C11 and C12 and discovered that too much past had built a shortcut under C11. After cleaning and resoldering all voltages were good and test are OK. Well, it's not perfect ! I've lost a 0.047uF will desoldering (the little beast jump somewhere).
      For now the kit is working only with C11, I've placed an order to replace the other.
      I've tried-it with a wire hooked to the antenna input, an EMU-202 and SDR#. I was able to get some signals on the screen, which make me really happy.

      Thanks KB9YIG for all the work, the quality of the kit and the fast shipping.
      Thanks to WB5RVZ for all the documentation. If I succeeded, it's only with the help of your website (old and new).
