Re-read Part 97 about automatically controlled stations.  Please point out
to me where a 1200 bps AFSK data transmission using FM on 144.39 which is
not responding to an interrogation is allowed.

Part 97 is very specific about automatic control:

§97.109 Station control. 
(d) When a station is being automatically controlled, the control operator
not be at the control point. Only stations specifically designated
elsewhere in 
this Part may be automatically controlled.

§97.201 Auxiliary station. 
(b) An auxiliary station may transmit only on the 1.25 m and shorter
bands, except the 219-220 MHz, 222.000-222.150 MHz, 431-433 MHz and 435-438
(d) An auxiliary station may be automatically controlled. 

§97.203 Beacon station. 
(d) A beacon may be automatically controlled while it is transmitting on
28.20-28.30 MHz, 50.06-50.08 MHz, 144.275-144.300 MHz, 222.05-222.06 MHz,
432.300-432.400 MHz segments, or on the 33 cm and shorter wavelength bands. 

§97.205 Repeater stations. 
(d) A repeater may be automatically controlled. 

§97.221 Automatically controlled digital station.
(a) This rule section does not apply to an auxiliary station, a beacon
a repeater station, an earth station, a space station, or a space
(b) A station may be automatically controlled while transmitting a RTTY or
emission on the 6 m or shorter wavelength bands, and on the 28.120-28.189
24.925-24.930 MHz, 21.090-21.100 MHz, 18.105-18.110 MHz, 14.0950-14.0995
14.1005-14.112 MHz, 10.140-10.150 MHz, 7.100-7.105 MHz, or 3.620-3.635 MHz 
(c) A station may be automatically controlled while transmitting a RTTY or
emission on any other frequency authorized for such emission types provided 
(1) The station is responding to interrogation by a station under local or 
remote control; and
(2) No transmission from the automatically controlled station occupies a 
bandwidth of more than 500 Hz.

I fail to see where a tracker being controlled (turned on and off is
control) by a non-licensed person which is transmitting on 144.39 meets any
of these conditions.  Maybe you can enlighten me.
