[hpsdr] Penelope - DUC Transmitter

[Phil Harman]

All,

Sorry about the delay in getting the details regarding 'Penelope' -  the 
companion transmitter to the Mercury receiver - details on the Wiki.

I've just uploaded the first cut at the specification and a block diagram to 
the Wiki at

At the moment I have the basic FPGA code running and Bill KD5TFD has made 
the required changes to PowerSDR to enable me to start testing.  The AD9744 
DACs have just arrived and I will add one to the prototype board during the 
week -  heat wave permitting!

Special thanks to Lyle for agreeing to lay out the PCB, he did a fantastic 
job on the Janus board and I am sure we will have similar success with 
Penny.

Please feel free to offer any suggestions or requests for features so we can 
consider them. I've allowed for a low level output to drive a transverter, 
what would be a suitable level,  +10dBm?
