... it is so very hard to get the average ham 
to respond with signal reports when there is jammer 
or stray signal on the air.  The usual responses are:
1)  Im mobile,
2)  I dont have any DF equipment.
3)  I dont have a beam.
4)  I cant easily listen on the input
5)  I cant remember how to do REV on this rig
6)  Maybe tonight I can do something
7)  I only have an omni antenna...
8)  I'd have to change radios
8)  Get someone with some DF equipment to help
10)  I cant hear anything
*** ATTENTION ***  None of those excuses in any
way prevent that station from giving good valuable
data to help locate the signal.  All we need are: 
a) His location
b) His Antenna height, gain, directivity
c) A signal report including the very valuable 0.
d) A map to plot all this data on... 
Now, APRS already is transmitting (a) and (b), and
has (d), so all it needs is a single digit -c- from several 
stations to localize the signal.
