      Hi Andy,

      The RX BW is set from 50 to 4195 Hz (Anan100/D)
      The spectrum is flat from 100 to 4100Hz.
      Traces are

      perfectely visibles on waterfall from ~100 to 2500 Hz for JT65
      and decoded 100%
      Traces are also perfectly visible from

      2500 to 4000Hz for JT9
      JT9 are decoded if level is over ~ -15 to -20 dB like "Multi" with JT65-HF
      JT9 is decoded for

      lower levels ONLY if i double click on the corresponding
      trace.
      If i leave the cursor on the trace, next trace(s) are

      perfectely decoded
      "automatically".
      At the same time, JT65 signals are perfectly decoded until -24 dB

      Sorry but it's
      difficult for me to explain in English language hi !

      My best 73,

      Rudi
