Here is some information on forthcoming Titan IVA launch from the VAFB
extracted from unclassified initial launch alert message (ILAM) for
this launch (initial variant for Jul 16 launch, I assume).

Name:           TITAN IVA/NUS, A-18/K-18/NUS
Launch azimut:  153.0000 DEG
Launch window:  16 JUL 97 0529Z TO 16 JUL 97 0859Z

   Sequence of events

Event                        HH:MM:SS

Liftoff                      00:00:00
Stage 1 ignition             00:01:57
Stage 1 shutdown             00:05:02
Stage 2 ignition             00:05:02
Jettison stage 1             00:05:03
Stage 2 shutdown             00:08:38
Park orbit injection         00:08:58

Objects to achieve orbit:

Two - payload and 2nd stage rocketbody. The payload parameters are classified.
The Stage 2/Payload combination is approximately 115.6 feet by 16.7
feet.  It is three axis stabilized.  There will be a strage 2
retrograde burn to separate the pieces.

Communications frequencies:

The Titan core vehicle transmits two data streams:
(1)  PCM 384 KBPS remote monitoring instrumentation system (RMIS)
     data on 2287.5 MHZ
(2)  Analog wideband instrumentation system (WIS) data on 2255.5 MHZ
  NOTE:  The analog and digital data streams are each relayed through
         two separate antennas; only one WIS, and one RMIS antenna is
         transmitting at one time.
In addition, there is a C-band radar beacon, radiating through two 6
separate antenna. The beacon can be interrogated through either
antenna at any time tuned to 5765 MHZ.
