Actually, aprs.fi does store the original binary packet that it received, 
and in a storage format that is binary clean (NULL bytes are shown, and 
all). The default "normal" raw packets view shows non-printable bytes in 
pink hex codes, '<0x1c>' stands for one byte having value 1C, like here:


For other software developers there are also the hex dump view which 
helps in counting the number of space/tab characters and such:


and the decoded view, displaying what our parser gets out of each packet:


Just toggle from the drop-down menu on the top.

Looking at the linked packets closely might reveal a couple of bugfixes, 
but more on those in another email. :)
