(b) Balloon: The U. S. Weather Bureau released a weather balloon
from its weather station at Victoria, Texas, at O5l5 on the date of the
sighting. Telephone ersations with a Mr. Jones at Victoria revealed
the path of balloon epicted on the attached maps. The path informa-
tion was taken from the weather station's official records. These
records indicated the balloon burst at an altitude of 30,620 meters
(10l,046 feet) at O657 CST. Since the time the balloon burst was almost
two hours before the UFO sighting (o845 CST), it appears that this
balloon could not be an explanation for the UFo sighting.

Certain military control towers transmit on high frequencies such as 3053 ke. and 6723 ke., and other communication stations which are
not shown on sectional charts operate on a number of frequencies in the M/HF bands.
Radio broadeasting stations (AMl), which are extensively used for aireraft homing, transmit on frequencies between 535 ke. and 1605
ke. A selection of these broadcasting stations which are suitable for air navigation are shown with call letters and frequeney on aeronautical
charts.
500 ke. is the international distress frequency for ships and aircraft over the seas.

advisory service). -
136.1-144.0 mc.; 148.0-150.8 mc. Assigned primarily for government use, though frequencies in these bands are often available at FAA **
control towers, and (ARTC) centers for communication with military aircraft. 143.90; 148.15 me. assigned as Civil Air Patrol frequencies. -
Ultra High Frequencies (UHF)
In common aeronautical usage, frequencies in the international VHF band above 225 me., in addition to the 300-3000 me. UHF band;
are termed ultra high frequencies. Ali UHF voice channels are both transmitted and guarded.

Use of Frequencies in Voice Communication
Voice communication is not available at all radio ranges and radiobeacons. Facilities without voice are indicated on sectional charts
by a note "No voice" in the lower line of the box.
In any eommunications with FSS or tower, the frequency on which reply is expected should be specified in the initial call. T
For L/M/HF communication, FAA control towers normally guard the high frequeney 3o23.5 ke. Reply from FSS will normally be
