Engineering Report For
CRC Media West LLC
KPSF(AM)
Cathedral City, California
March 2012
This engineering report documents the Directional Antenna Performance Verification
measurements for KPSF (AM), FCC facility ID number 161373, Cathedral City, California.
KPSF is authorized to operate on 1200KHz with 5 KW using a three tower directional antenna
daytime and 1.3 KW nighttime using a five tower directional antenna. This Verification is for the
new facility authorized by BMP-20 1201 25AAB and documents the required "model proof' in
order to grant the covering license. All measurements were made personally by the writer in
accordance with the FCC rules at 47 CFR 73.151(c).
Eligibility for 73.151(c) Processing
The KPSF antenna system consists of five conventional uniform cross-section insulated
steel radiators, series-fed with no top loading. They are 106.9° tall at the KPSF frequency (1200
KHz) and are sampled at the base using Delta TCT-3 toroidal current transformers. The ground
system is of standard design, consisting of 120 equally-spaced buried bare copper wire radials
around each tower 74.25 meters long (106.9°) except for those which intersect, with 4" copper
straps terminating the radial intersections and interconnecting the towers. A 4" strap
interconnects the towers to each other and to the phasor and transmitter. There was no change in
the physical configuration of the towers or ground system from that licensed for KXPS.
Background
The KPSF antenna system shares towers with KXPS (facility ID 22342), licensed to
Thousand Palms, California. The implementation of the construction permit did not require any
additional construction except for the installation of the proper equipment. No changes were
made to the towers or ground system. The filters used to isolate each station are of a standard

design and are documented later in this report. The antenna current sample elements are Delta
Electronics TCT-3 current transformers and are located at the input to the series filters. There are
no shunt elements between the filter and the tower except for the static drain or tower lighting
choke which presents a very high impedance (more than 10 times the tower impedance) at 1200
KHz. Equal lengths of RFS 3/8" LCF38-50J Cellflex foam coaxial cable are used as sample lines.
A Potomac Instruments AM-19D (210) antenna monitor is used to keep tabs on the array. The
monitor was refurbished, recalibrated and checked for proper operation in accordance with the
manufacturer's instructions. A statement of calibration is attached.
Measurements
The KPSF system was modeled using Westberg Consulting's Phasor Professional 2.1 .1
which calculates the tower matrix values as well as the proper operating parameters. The towers
and sample lines were measured and documented using an Array Solutions PowerAIM-120
network analyzer serial number 1019 operated in accordance with the manufacturer's
instructions. This analyzer has been used in several recent projects and exhibits excellent stability
and field performance and since it operates 'floating" via battery power and a Bluetooth radio
connection to the associated computer no RF ground loop issues arise.
The five KPSF towers are identical and are base sampled using toroidal current
transformers. Each tower was disconnected from its ATU at the sample transformer using the
jack installed for this purpose and was measured at that point. The other towers were individually
shorted and/or left floating for each measurement as required, plus additional measurements with
the subject tower base insulator shorted to measure the feedline impedance and electrical length
from the ATU to the tower as well as at the tower itself with the ATU disconnected. These
measurements are documented below and show good agreement with the Westberg theoretical
numbers.

The Westberg Phasor Professional method-of-moments mode! fully complies with all FCC
requirements for tower radius, height, segment length, and calculation references points. No
shunt capacitance was used. Towers were adjusted by varying the propagation velocity as shown
above. The measured impedances agree with the model within +1- 2 ohms +1- 4%. Westberg's
Phasor Professional uses a single wire of the desired effective radius divided into segments or no
more than 100 electrical length each to model the tower.

Sample System Verification [47 CFR 73.15 1(c)(2)]
RFS 3/8" LCF38-50J foam dielectric Celiflex coaxial cable

Sample Lines:

88% velocity factor, 50 +1-I ohms
Lines were cut to equal electrical length and terminated with proper connectors. An additional
short (five foot) Times Microwave LMR-400 flexible cable connects the 3/8" Cellflex to the
antenna monitor. The LMR-400 cable has very similar electrical characteristics to the LCF38-50J
and "looks" like part of the Celiflex cable. These jumpers are identical and are accounted for in
the data which follows.
Sample Element Type:

Delta Electronics TCT-3 Toroidal Current Transformers

Location:

At output of antenna tuning network and diplex filter.

Operating Potential:

TCT-3 Phase and Ratio Test (Tower 2 is reference):

1.002/+0.10

Tower 3:

1.003/+0.30

Tower 4:

0.997/ -0.4°

Tower 5:

1.001/+0.10

(Current Transformers are matched within +7-0.30% ratio and +7-0.35° phase)
The phase and ratio calibration test was done with transformers removed from the ACUs and
configured in pairs with the #2 transformer adjacent to each other reading RF current to tower #2
in day pattern at 500 watts. The cables used to connect the TCTs to the monitor are identical in
electrical length and characteristic impedance and are normally used as flexible jumpers from the
sample line to the antenna monitor.

Engineering Report
PLACEHOLDER PAGE
Pages 24 and 25 of this Engineering Report (containing certain reference point
measurements) could not be completed as of the required filing date for this application
because high winds (the reason for the tolling of this Construction Permit from 3/5/12 to
3/12/12) continued unabated this week and caused clogging to the radiator for the
electrical generator that powers the facility and thus caused the generator to overheat,
resulting in an inability to operate the station at the required levels necessary to take such
measurements. While the generator has now been repaired, there is insufficient time to
take the measurements and produce the datum before the paper copy of this application
must be filed. Thus, Mark Mueller (Tecimical Consultant) will submit these two pages
electronically to Son Nguyen (Audio Division) to insert into the paper application as soon
as they are completed.

Tower Survey [47 CFR 73.15 1(c)(1)(ix)]
The three KPSF towers were surveyed on February 2, 2012 by Phillip K. Fomotor, a
licensed Professional Land Surveyor in the state of California (license number 7070) of Fomotor
Engineering, Palm Springs, California and were found to be as follows:
Tower 1 (5) to 2 (SC): 324.5 feet (142.46°) at 28.07° True (theo.

=

142.6° at 23° T)

Tower 1 (S) to 3 (NC): 648.9 feet (284.88°) at 28.110 True (theo. =285.20 at 230 T)
Tower I (S) to 4 (N): 973.6 feet (427.43°) at 28.12° True (theo. = 427.8° at 23° T)
Tower 1 (5) to 5 (W): 541.2 feet (237.60°) at 321.21° True (theo.

=

237.6° at 320° T)

A copy of the sur vey report is attached. This corresponds to a maximum relative spacing
error of 0.4° and absolute bearing error of +5.12° (see below) for towers 2, 3 and 4. The
theoretical tower spacings and orientation were used in the model.
The KXPS licensed tower spacings and orientations were used to prepare the underlying
KPSF construction permit application and no physical changes were made to any of the towers. It
appears that the 5 degree orientation error dates from the original KXPS construction in 1990. An
evaluation of the allocation impact of the shifted tower line reveals almost no change to the
daytime contour locations and the station can be granted interim PTA at full power with no risk of
prohibited contour overlap. At night, KPSF can operate at 600 watts pending the grant of the
application which makes small changes to the tower 4 and 5 parameters to provide the required
protection to WOAI. No other stations are affected.
The application to change the towers 2-4 orientation to reflect those from the survey will
be filed immediately. Tower 5 is unaffected.

Construction Permit Conditions:
1 Permittee shall install a type accepted transmitter, or submit
application (FCC Form 301) along with data prescribed in Section
73.1660(b) should non-type accepted transmitter be proposed.

KPSF has installed a new Nautel XR-6 which the transmitter manufacturer states is type accepted
for the power levels and intended service.
2 The permittee must submit a proof of performance as set forth in either
Section 73.151(a) or 73.151(c) of the rules before program tests are
authorized.
A proof of performance based on field strength measurements, per Section
73.151(a), shall include a complete nondirectional proof of performance, in
addition to a complete proof on the (day) and (night) directional antenna
system. The nondirectional and directional field strength measurements must
be made under similar environmental conditions. The proof(s) of performance
submitted to the Commission must contain all of the data specified in
Section 73.186 of the rules. Permittees who elect to submit a moment method
proof of performance, as set forth in Settion 73.151(c), must use seriesfed radiators. In addition, the sampling system must be constructed as
described in Section 73.151(c) (2) (i)

The KPSF antenna system was verified using the "model proof' rules at 47 CFR 73.151(c). The
towers are series-fed and the sample system meets the requirements of 47 CFR 73.151 (c)(2)( 1).
This is the required report and filing.
3 Licensee shall be responsible for satisfying all reasonable complaints of
blanketing interference within the 1 V/m contour as required by Section
73.88 of the Commission's rules.

The transmitter site is in an undeveloped desert area with zero population inside the 1 V/ni
contour so no blanketing interference complaints are expected.
4 Before program tests are authorized, sufficient data shall be submitted
to show that adequate filters, traps and other equipment has been installed
and adjusted to prevent interaction, intermodulation and/or generation of
spurious radiation products which may be caused by common usage of the same
antenna system by Stations KPSF and KXPS (ID#22342) and there shall be
filed with the license application copies of a firm agreement entered into
by the TWO stations involved clearly fixing the responsibility of each with
regard to the installation and maintenance of such equipment. In addition,
field observations shall be made to determine whether spurious emissions
exist and any objectionable problems resulting therefrom shall be
eliminated. Following construction, and prior to authorization of program
test under this grant, BOTH stations shall each measure antenna or common
point resistance and submit FCC Form 302 as application notifying the
return to direct measurement of power.

KXPS has installed pass-reject traps at all five towers as shown below. Each is of standard
design and sufficiently isolates the two stations to prevent both interaction and spurious
emissions. Even though the two stations are under common ownership a formal maintenance
agreement is attached. Field observations indicate -84 dB or better suppression of all harmonics
and mix products. Spurious and harmonic emissions measurements from 540 KHz through 5
MHz were made March 8, 2012 outside the transmitter building, which is approximately at the
center of the array, with each station operating at full daytime power. These measurements, taken
with the write?s Potomac Instruments FIM-4 I field intensity meter show that there is excellent
isolation between the transmitters:
