[hpsdr] Mercury V2.4

[Joe Martin K5SO]

Joe,

That's interesting.  My Mercury V2.4 seems to work just fine here;  
I've had it running for hours at a time without a single hitch.  Also,  
I don't see any board position dependencies here at all.  I keep  
expecting to see some though based on the postings I've seen but so  
far I seem to be able to put anything anywhere on my Atlas board.  I  
wonder if some of the differences seen on different board sets are due  
to differences in the details of the component placements and  
soldering (especially soldering on the J1-J6 jack pins) on Atlas by  
different folks(?).  Maybe I gobbed my Atlas solder job up just right  
so that I serendipitously get beneficial cancellations on the bus(?).

For the record, Mercury's latest ADC overload function seems to work  
as advertised here; comes on with a -12dBm input signal.

I'm still looking for quirks though; maybe there are some I've not  
stubbled across yet, who knows.

73,  Joe K5SO
