 Something new I just started playing with is APRS for use as a DF tool.
 Using Automatic Position Reporting System software you can now do DF'ing 
ith
only one base and some other mobiles or bases.
 The version of the software I have is APRS796.ZIP for DOS.
 This ZIP compressed file can be downloaded from:
Landline BBS:

 Once you have the APRS software ZIP,make a a directory on your hard-drive
called APRS.  (ie: C:\APRS )
 To de-compress the APRS796.ZIP archive you -MUST- use the following command:
   pkunzip -d aprs796.zip  C:\APRS
 This will undo the ZIP,and create all the sub-directories structure of the
APRS software on the C:\ drive in a directory called APRS.
 Read the docs that came with it for more info on how to use it.
 In the documentation that comes with this version of the software there are
text files describing how to use the APRS software for DF-ing a signal while
using omni-directional antennas and only one base station set-up.
 While I am still reading the documentation and playing with the software 
ere
on my Baycom TNC,I thought it would be of interest to those having problems
with local repeater jammers or into "fox-hunting" who may want to get a copy
of the software to play with and experiment for themselves.
 I'll post more on it after I finish reading the docs some more and do some
more DF testing.
