[hpsdr] Come and get it, code's ready!

[Steve Bunch]

Just updated Mercury and Penelope to 2.7, and it's working very well  
for me.  (Updated Janus but have not tried it yet.)

I had previously been experiencing frequent pops/dropouts at 192K  
(less often at 512 than with larger buffers), and less often but still  
happening at 96K.  Now running at 192K/2048 and 1024 w/o problems  
other than occasional lightning-induced ADC overloads -- shutting down  
soon!

Hardware here is a 2.4GHz Core 2 quad with 4GB RAM, intel DP35DP  
motherboard, motherboard USB, separate graphics board, TAPR-built  
HPSDR boards running from a PC power supply, board order randomly  
chosen as Penny/Ozy/Mercury in J6 (closest to P/S)/J5/J4.  Software is  
WinXP SP3 32-bit, McAfee virus protection on, .NET 3.5 SP1, a few  
other things running, but nothing big.  Listening to AM radio is  
taking a bit over 30% of one processor with 192K/2048 sampling, CPU  
affinity set to CPU 3 only, scheduling RT, running a full-width  
waterfall, no NR/NB/ANF -- a configuration that previously generated  
lots of pops/dropouts.  CPU Time is split a bit under 1/4 system time,  
3/4 user (per Process Explorer).  These same settings used to pop at  
least once or twice per waterfall screen, so this is a big improvement.

Thanks to Kirk, Bill, and Phil for all the hard work on this!
