Purpose of Application

This engineering exhibit supports an application by RADIO LICENSE HOLDING SRC LLC
(“RLH”) for a modified station license for radio station KTCK(AM) Dallas, TX (Facility ID 8773)
following the installation of diplexing equipment to allow KLIF(AM) 570 kHz Dallas to operate
from the KTCK antenna array. This construction also involved new tower lighting, as well as
removal of an unused transmission line on tower #4. Therefore the procedure outlined in 47
CFR §1 .30003(b)(2) has been followed and are described in this report.
Information is provided herein demonstrating that the directional antenna parameters for the
pattern authorized by the station license have been determined in accordance with the
requirements of section §73.151(c) of the FCC Rules. The system has been adjusted to
produce antenna monitor parameters within +1- 5 percent in ratio and +1- 3 degrees in phase of
the modeled values, as required by the Rules.
While KTCK is licensed at a nighttime power of 5 kW, the station operates under a restricted
RMS of 634.1 mV/m/km, which is roughly equivalent to 2.1 kW. The nighttime model in this
report is based on this power.
All measurements contained in this report were made by Benjamin F. Dawson Ill P.E and the
undersigned engineer.

Analysis of Tower Impedance Measurements to Verify Method of Moments Model

KTCK

Tower base impedance measurements were made at the locations of the sample system
current transformers using a Hewlett Packard 8751A network analyzer in a calibrated
measurement system. The other towers were grounded.
The reference point impedance measurements are listed in the table below.

Circuit calculations were performed to relate the method of moments modeled impedances at
the tower base feed points to those at the measurement locations as shown in the diagram
titled Analysis of Tower Impedance Measurements to Verify Method of Moments Model.

The measurements above were made with the pass 570/ reject 1310 filters connected at the
tower under measurement.

Item 2
Method of Moments Model Details for Towers Driven Individually

-

KTCK

The array of towers was modeled using Expert MININEC Broadcast Professional Version 14.0.
One wire was used to represent each tower. The top and bottom wire end points were
specified using electrical degrees in the geographic coordinate system, using the theoretical
directional antenna specifications for tower spacing and orientation. Each tower was modeled
using 30 wire segments. As the tallest tower in the KTCK model is 241 electrical degrees in
height, the maximum segment length is 8 electrical degrees.
Each tower’s modeled height relative to its physical height falls within the required range of 75
to 125 percent of the actual tower height. The array consists of four uniform cross section
triangular towers each having face widths of 36 inches.

Method of Moments Model Details for Directional Antenna- KTCK

The array of towers was modeled using MININEC with the individual tower characteristics that
were verified by the individual tower impedance measurements. Calculations were made to
determine the complex voltage values for sources located at ground level under each tower of
the array to produce current moment sums for the towers that, when normalized, equated to the
theoretical field parameters of the authorized directional antenna patterns. In the schematic
diagram on the following page,
X represents the capacitance between the tower and ground, including the base insulator
X represents the series inductance of the feed line connecting the ATU to the tower
represents reactance of the tower lighting transformers (Austin ring transformers)
XFIL represents the reactance of the pass 570 I reject 1310 filters
XLT

The values used for Xc,

XLT

and are based on values obtained from the manufacturers.

Xc for tower #4 differs from the others as towers 1, 2 & 3 were replaced after being destroyed in
a storm which tower 4 survived.
In all cases, the modeled impedance at the reference point is within one ohm of the measured
reference point impedance.

As shown in the tables above, the base voltages used in the Method of Moments computer
model produce current moments in each of the towers that are identical to the field ratios and
phases (+I 0.10) of the theoretical antenna parameters specified in the KTCK construction
permit.

Item 4
Derivation of Operating Parameters for Directional Antennas

-

KTCK

The currents at the tower reference points have been calculated by using the computer circuit
simulation program pspice. A pspice model has been made for each tower using the antenna
base currents and base impedances calculated by MININEC and shown in the driven array
model above, and the reactances listed previously in the table Analysis of Tower Impedance
Measurements to Verify Method of Moments Model. The magnitude and phase of the current
source in the pspice model was adjusted so that the current calculated in the output branch of
the pspice model (the current through resistor RL) was the same as the base current for the
tower calculated by MININEC. The current at the reference point is the current source in the
pspice model. These calculated currents are then normalized to the reference tower to obtain
the antenna monitor phase and ratio readings, as shown in the tables labeled Antenna Monitor
Parameters, which follow the pspice data below.

Direct Measurement of Power KICK
-

Common point impedance measurements were made using a Hewlett Packard 8751A network
analyzer in a calibrated measurement system. The measurements were made at the phasor
cabinet input jack adjacent to the common point current meter that is used to determine
operating power. The common point impedance was adjusted to 50 jO at the common point,
then the reactance was adjusted for minimum reflected power at the transmitter output. The
final measured common point impedance is 50 -j6 for both day and night operation. The
common point current specified on Form 302 results in an antenna input power of 2.3 kW, the
power specified in the current station license.
