      Hi,

      The same problem was here with Ensemble RXTX. Problem was solved with correct IQ channels swap.

When I enter 10.0 in the Real box and click on Calibrate, I find that WWV now shows up on 10.01184. This is a correction in the wrong direction (i.e. a sign problem). The I/Q channels seem to be correct. Am I missing something obvious? I have older Softrock RXTX v6.3 and that calibrated easily.
