EXECUTIVE SUMMARY

This engineering exhibit has been prepared in support of an application for licensing for
radio station WREC, Memphis Tennessee, Facility ID #58396. Measurements included
comply with the requirements of Rule Section 73,151c.

The towers and ground system remain as described in current license BL-20100513ALV.
The antenna tuning units and phasing system have been replaced with new components
of modern design and the system adjusted to operating parameters computed using the
Moment Method process as described in Rule Section 73.151c. Mininec Broadcast
Professional version 14.6 by EM Scientific Inc. was used in the analysis.

The system has been adjusted to produce directional antenna parameters within +/-5%
in ratio and +/-3 degrees in phase of the modeled values as prescribed in the Rules.

All measurements contained in this report were made by Mr. Jacob Wyatt of the iHeart
Media Corporate Engineering Staff or the undersigned.

Please refer any questions regarding this report to:

Itemi

Analysis of Tower Impedance Measurements to
Verify Method of Moments Model

Impedance measurements were made of the individual towers with the other tower
bases open. Measurements were made using a Hewlett-Packard 8753ES network
analyzer and a Tunwall Radio directional coupler in a calibrated measurement system.
Measurements were made immediately adjacent to the toroidal antenna sampling
transformers, inside the antenna coupling units. These measured values were related to
the modeled values obtained using the WCAP nodal analysis package. Heights of the
towers were adjusted as permitted by Rule Section 73.151c(1). Towers are triangular,
self-supporting, each leg fed from a common point (spider fed). The tower radii were
modeled at their actual values. The towers were segmented so that each segment is
less than ten (10) degrees in length.

loading remains unchanged and as previously licensed.

Item 2

Method of Moments Model Details for Towers Driven Individually

The model was verified by comparison of modeled to measured tower impedances. The
tower resistance and reactance were measured immediately adjacent to the toroidal
base sampling transformers, inside the antenna tuning unit cabinets. The measured and
modeled impedances were correlated using the Westberg Consulting WCAP Pro
software program. WCAP is based on the SPICE nodal analysis program. The shunt
capacitive reactance of the tower base insulator is represented in the drawing below as
Xc. The series inductive reactance of the tower feed conductor is represented as Xl. Z
model represents the modeled impedance of the tower and Zin represents the
impedance measured at the sampling point. In the following WCAP tabulations, the
modeled impedance is represented between nodes 2-0. The measured impedance is
represented between nodes 3-0. Node 0 represents ground. The calculated reference
point impedances appear under the "TO NODE IMPEDANCE" columns of the WCAP
calculations, following the insignificantly short transmission line (IL 1-3) that was
included in series with the drive current sources (I 0-1) to provide calculation points for
the impedances.

Sampling System Measurements

The following calculations confirm that the sample system as installed complies with
Rule Section 73.151©(2)(1) in all respects, The sample torroids are Delta model TCT3
and their outputs are in agreement within the manufacturer's specification of +/-2% and
+122. The antenna monitor is a Potomac Instruments model 19. The monitor's
calibration was checked against an Agilent 8753ES network analyzer and found to be
operating within the manufacturer's specifications. Additionally, the sample lines
consist of coaxial cables which are constructed of a copper clad aluminum center
conductor, polyethylene foam dielectric, solid, corrugated outer conductor with a black
polyethylene jacket. The cables are equal in length within 1 as required. All cables have
been buried so as to be exposed to the same environmental conditions. The length of
the cables was confirmed by measuring the impedance, looking into the line with the far
end opened. The lines were found to be 3/4 wavelength long at the frequencies listed.
These frequencies were used to calculate the electrical lengths of the lines at the
operating frequency of 600 kHz. Frequencies were calculated at which the lines were
+1- 452 the length of the resonate frequency. The impedance was then calculated using
the following formula:

The sample torroid calibration was confirmed by passing a common conductor through
the torroids. The common conductor was driven by a Hewlett-Packard 8753ES vector
network analyzer that was properly calibrated for response measurement. The output
from the tower #1 torroid was fed to the reference receiver of the analyzer and the
other output was alternately fed to the B input. The output of the tower 2 torroid was
compared to that of the tower 1 torroid and the results noted in the chart below.

Direct Measurement of Power

The common point network in the nighttime phasor was adjusted to provide the proper
operating resistance of 50 ohms and a reactance of 0 (zero) ohms to the transmitter
output. In order to compensate for hookup inductance between the power
measurement point and the transmitter the common point reactance was set for a
value of-j7 at the measurement point. The nighttime operating powers were
calculated by adding 8,0% to both the daytime and nighttime nominal operating power
of 5.0kw. The common point current was then calculated as indicated below.

No day reference points were performed per an understanding between the

is essentially non-directional and there were no pre-existing day monitor points on the

RFR Compliance

Operation of WREC at 5.0 kW daytime and

5.0 kW nighttime will not result in exposure

of workers or the general public to RF radia

tion in excess of levels specified in 47CFR

1.1310. Fences have been installed arou

nd all tower bases to comply with the mini

mum

distance which exceeds the distances spec

ified in OET Bulletin 65 for this frequency,

calculated power levels in the towers and
exposure greater than permissible levels.

tower height to prevent electric and mag

netic

These fences limit access by the general

public. If it becomes necessary for workers
maintenance, the station will either reduce

to enter the tower base areas for

power or cease operation to provide RFR

safety for the workers.
