For a pure transmitter you don't need Janus - you can use the mic 
input on the Penelope board, and make the appropriate selections on 
Setup->General->HPSDR.

However, if you're going to do receiving as well  then you will want 
to use Janus -- if you use any other audio input card Penelope will 
not work since we'll not be sending the Audio data thru Ozy.

Hmm ... I've done this with an SDR 1000,  connect receive output of 
SDR 1000 to Janus and use Penelope as xmitter,   but I suspect the 
current software may have a glitch with the Soft Rock.  The glitch is 
this - for the Soft Rock we vary the IF to receive since we can vary 
the mixer frequency.  I'm not sure what the code will do when 
Penleope and soft rock is configured .. good chance we'll use the IF 
frequency for the Soft Rock and not the direct freq Penelope 
needs.    Will have to add this config to the list of things to think 
about a bit.
