[hpsdr] Ozy/Janus Operating Manual available for download

[Joe - AB1DO]

High Pete,
I have tried to answer your questions in line, but again I'm only the 
messenger. Someone else may also want to jump in. Pointer on manual 
indications is well taken and will be looked at when I get to revision 2.

Thanks,
73 de Joe - AB1DO

[AB1DO] Yes, the various calibration steps are still necessary. These steps 
(frequency, level and image reject), are all software (DSP) related.

[AB1DO] Sample rate is definitely valid with Janus, and if I'm not mistaken 
audio buffer size is too.

[AB1DO] Yes, it refers to a MONO plug. If you insert a mono plug in the 
JANUS mic/PTT jack, the sleeve of the mono plug will short the ring and 
sleeve connections of that JANUS mic/PTT jack. If you have set the PTT 
jumper to the ring setting, then the sleeve of the mono plug will 
permanently connect PTT to ground, thus activating PTT. If you leave the PTT 
jumper unset, however, (i.e. your mic has no PTT switch), then there should 
be no issue and you can safely use your MONO mic plug.

[AB1DO] Yes, the SDR MOX button functions as before. When you click MOX on 
the front console of PowerSDR, the software sends the appropriate control 
command (either through the parallel port, the USB Adapter or Ozy, whichever 
you are using), to set the TX/RX relay
