Running Penny and a Softrock may be a bit weird with the current 
software.  I think the SW will only allow you to set VFOs to Soft 
Rock center freq+/- sampling rate/2  and I suspect there will likely 
be some IF issues as well since  the SW will be offsetting the IF to 
match the SR center freq even for transmit which is not what Penny 
will need.  SR + Penny is not a configuration I've given much thought to.

Yes.  The hardware is capable of just above DC up to about 60 
MHz.  PowerSDR software will limit you to the ham bands.  SIg Gern 
stuff could be done with appropriate software.

>3. What about the Lowfer guys on 500 KHz and 137 KHz?

I'm pretty sure Penny can get down to 500 or 137 khz.  Phil H would 
know for sure - but I believe he's in Dayton this week.
