... 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. ...
