Purpose of Application

This engineering exhibit supports an application for a "moment method license" for the
presently authorized and unmodified antenna radiation patterns of radio station KRDC,
Pasadena, CA. KRDC is authorized per license to operate on 1110 kHz with a power of 50 kW
day and 20 kW night, employing separate directional antenna patterns for the daytime and
nighttime operation. This application replaces the previously filed license allocation due to the
modification of the translator antenna on one of the towers of the KRDC array. This
modification is required by 47CFR73.10003(2) since the change of the translator antenna
resulted in a change of the "standalone" impedance of that tower by more than the allowable
margin.

The antenna towers and ground system are unmodified from their long-established conditions
and adjustments of the antenna parameters were made in accordance with the terms of the
license and specifications provided for the previous licensing of the station. 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. Measurements described in this report were made by Burt
Weiner and Ashley Wallen under my direction.

Item I
Analysis of Tower Impedance Measurements to Verify Method of Moments Model - KRDC

Tower impedance measurements were made at the locations of the sample system current
transformers using an AIM-I 20 network analyzer in a calibrated measurement system. The
other towers were open circuited at the same point where impedance measurements were
made (the "reference points") for each of the measurements.

Circuit calculations were performed to relate the method of moments modeled impedances at
the tower feed points to those at the current sample device locations as shown in the table.
The base conditions shown for each tower, which includes the stray capacitances, were used in
the moment method model as a load at ground level for the open circuited case. The lighting
transformers in use on three of the towers and the newly installed FM isocoupler on one tower
have been included in the models because of the high impedance of the 132 degree tall towers.
The sample line isolation coils are detuned (parallel resonated with a vacuum variable
capacitor) and it is not necessary to include them in the model.

The following page shows the schematic of the assumed circuit and tabulation of calculated
values. These calculations show the impedance transformations between the tower base
values produced by the MININEC moment method model and the "J" plug locations where the
measurements were made.

NOTE: The tower numbering for the 5 antenna towers employed by KRDC is potentially
confusing, because the numbering in the CDBS database and given for the theoretical pattern
on the station license differs from that given for the operating parameters on that license, and
used on the station antenna monitor. All tower numbering in this report is labeled so as to
minimized the effects of this insofar as possible, including by showing the approximate
orientations of the towers, as NE, SW, etc.

Item 2
Derivation of Operating Parameters for Directional Antenna - KRDC
The method of moments model of the array, following verification with the measured individual
open circuited base impedances, was used for directional antenna calculations.

Calculations

were made to determine the complex voltage values for sources located at ground level at the base
of 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 pattern.

With these

voltage sources, the tower currents and phases were calculated. 33 segments were used for towers
in the moment method model. The currents and voltages at the sample loop locations on the towers
(segments 11,44,77, 110, 143) are shown.

Item 3
Method of Moments Model Details for Towers Driven Individually

- KRDC

The array of towers was modeled using MININEC. A single wire was

used to represent each tower,

which are uniform cross section.. The top and bottom wire end points

were specified using the

theoretical directional antenna specifications in electrical degrees. The

maximum and minimum

segment lengths are 4.273 and 3.985 electrical degrees respectively.
Each tower's modeled height relative to its physical height falls within
percent and each modeled radius falls within the required range of

the required range of 75 to 125

80 percent to 150 percent of the

radius of a circle having a circumference equal to the sum of the widths

of the tower sides.

Item 4
Method of Moments Model Details for Directional Antennas - KRDC
The array was modeled using MININEC with the individual tower characteristics that were verified by the
respective 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 pattern. The following pages contain details of the method of moments model of the
directional antenna pattern.

Item 6
Sampling System Measurements - KRDC

Impedance measurements were made of the antenna monitor sampling system using an AIM-120
network analyzer in a calibrated measurement system. The measurements were made looking into the
antenna monitor ends of the sampling lines for two conditions - with and without the sampling lines
connected to the sampling loops.

The following table shows the frequency closest to the carrier frequency where series resonance zero reactance corresponding with low resistance - was found. As frequencies of resonance occur at
odd multiples of 90 degrees electrical length, the sampling line length at the resonant frequency above
carrier frequency - which is the closest one to the carrier frequency - was found to be 450 electrical
degrees. The electrical length at carrier frequency appearing in the table below was calculated by
ratioing the carrier frequency to the resonant frequency.

The sampling line lengths meet the requirement that they be equal in length within 1 electrical degree.

The characteristic impedance was calculated using the following formula, where Ri + jXl and R2 + jX2
are the measured impedances of the +45 and -45 degree offset frequencies respectively:
Zo

= (®2+ X2)x®2+ X2))%

The sampling line measured characteristic impedances meet the requirement that they be equal
impedance within 2 Ohms.

Reference Field Strength Measurements - KRDC

Reference field strength measurements were made along radials of five of the eight pattern inflection
azimuths for the night pattern and four of the 6 for the day pattern. Both patterns are symmetrical
around the lines of the respective towers and one radial of each symmetrical pair has been included,
rendering measurement of the additional inflection radials unnecessary. The measured field strengths,
point descriptions, and measured coordinates are shown on the following page. The measurements
were made on July 7, 2017. The coordinates are NAD-27.

The measurements were performed by Burt Weiner and Ashley Wallen, who are experienced in the
proper techniques for such work. The measurements were made with a Potomac Instruments FIM4100 serial number 226. This instrument's calibration was checked by comparison with readings of a
Potomac Instruments FIM-21, serial number 803, which was most recently calibrated by the
manufacturer on March 3, 2016, and found to agree well within the manufacturer's stated accuracy for
the instruments.

The calibrating field is maintained equal to the National Instite of Standards and Technolo
(NIST)
standard field within an accuracy of 1.0 perceiit. NIST states that the absolute accuracy of its field is "believed
to be within 3.0 percent."
The error at points on the meter scale other than the calibration point is less than 3.0 percent. The attenuator
ratios are correct within 2.0 percent. These accuracies apply for battery voltages that are indicated by the
instrument's battery check circuit to be useable.

Item 8
Direct Measurement of Power - KRDC

Common point impedance measurements were made with a Delta OIB impedance meter. The
measurements were made at the phasor cabinet input adjacent to the common point current meter
used to determine operating power. The impedance measured at this point was adjusted to a value of
50 - J6 ohms for the day and night common point networks, providing the main transmitter with its
desired load.

Item 9
Antenna Monitor and Sampling System - KRDC
The antenna monitor is a Potomac Instruments model AM-I 901 serial number 106. The sample
transformers are connected through equal lengths of Andrew 3/8 inch foam Heliax solid outer
conductor transmission lines to the antenna monitor. The five sample lines are routed to the towers
such that they are subject to similar environmental conditions. The five identical sample loops are
mounted at approximately 32% of the total height of the towers (42 degrees from the base), such that
with 33 segments in the moment method model segment 11 on each tower (40 to 44 electrical
degrees) encompasses the location of the loops.

The antenna monitor calibration was checked by placing an RF feed divided into outputs with T
connectors and the outputs were connected with short, equal length coaxial cables to the in puts of the
antenna monitor. The resulting readings are well within the manufacturer's rated specifications.
