      Hi Joe,

      The UHFSDR kit is still sitting there in pieces in my lab pipeline...
      I envy that you already got the feeling of it and how the H-Mode mixer works in comparisson to the QSD/QSE we were familiar with.
      I didnt go into the trouble of building it on the beta board and patiently waiting Dave to anounce the new rectified boards.

      Appart from the first touches on PowerSDR-IQ for UHFSDR usage I didnt had the time to incorporate the requests done so far yet. But I will, since I also want to have the H-Mode mixer experience and SDR up to UHF.

      Although you had your Easter last week, its the Orthodox Easter here so you have my Season Greetings.

      Christos SV1EIA
