What are these files ?

Well my interest is in something called QRSS, a minority radio interest, 
so these files are not really meant for the masses !

Also stuff to support QRP'ers, Homebrewers, Raspberry Pi ham radio and 
general ham radio utils.

Many thanks to QSL.NET for hosting this stuff.
They really are worth chipping in a donation to.
THe older I get the more I appreciate what's being provided.
