[AMRadio] Off AM topic inquiry

[CL in NC]

While I am primarily a boat 
anchor fellow,  I do have one modern but now 30 year old rig, a 
TenTec Omni V.  I would like to know if any of you out there use the SDR equipment,  and if you actively write or modify the programs that run 
them.  I have read a lot about how you can mess with the software, write your own, what ever, but do not recall ever seeing an article, like a 
construction article for a real radio, that deals with a fellow 
describing the software he wrote for some SDR and how lit improved it's 
operation.  Is all the smoke on manipulating and rewriting the op system for this gear, just that,smoke?  Or is their a world out there that 
does not make it into the likes of QST where people are buggy over 
writing SDR software?  My train of thought goes along the lines of all the  mods folks suggested for every piece of tube gear made and were routinely published in CQ, QST, 73, and Ham Radio back in the day.  Are their folks who suggest changing a line of code in an SDR program to add a feature equivalent to  adding a pot and switch to a 32S3 to make it work on AM?
