/*
DB FILE DISC

<3 letter callsign>|<50 char base name and local>|<100 char base URL>|<50 char webmap URL>\NL

empty strings are allowed but no blank spaces between deliminators.( delim )
there must not be any blank lines after the last entry in the table. In fact,
it would be a good practice to insert the lines in alphabetical and numerical
order to eliminate replications and the problem of blank lines on the end of 
the file.
