Discussion:
The purpose of this Technical Brief for a Change of Facilities for CKKX-FM Channel
291A Peace River Alberta is to obtain authority for the actual parameters that CKKX-FM
is presently utilizing. The primary difference between what CKKX-FM is authorized for
and what the station is operating at is the height of the antenna. In discussions with
Industry Canada it was decided that the difference between the authorized antenna height
and the actual antenna is large enough that a Technical Brief for a Change of facilities is
required to amend the CKKX-FM parameters. It is proposed to utilize the existing
Channel 291 and to decrease the ERP from existing 2.8 kW to 2.5 kW and increase the
EHAAT from existing 78.0 m to 155.2 m.
To summarize the technical parameters of the new facilities, the following table has
been prepared:

Channel Selection and Interference Analysis:
3.1
Channel Selection
It is the intent of the applicant to utilize existing Channel 291A for this application.
This channel is presently used by CKKX-FM as a Class A station.
3.2
Channel Interference Analysis for the Proposed
CKKX-FM, Peace River, AB Channel 291A Operation
Distances between the proposed station and co-channel and adjacent channel
allotments or assignments were checked and in all instances meet the required
distance separations set out in Broadcasting Procedures and Rules, Part 3 and
Agreement Between the Government of Canada and the Government of the United
States of America Relating to the FM Broadcasting Service and the Associated
Working Arrangement (dated July 1997) amended February 2001.
3.3
Harmonic Interference
Broadcasting Procedures and Rules, Part 3 - Section C-6.1
The second harmonic of 106.1 MHz (Channel 291A) is 212.2 MHz. This falls in
television channel 13. The nearest channel 13 assignment or allotment is CFRN-TV-1,
Grande Prairie, AB which is 126.6 km at Azimuth 228.1° from the proposed site.
CFRN-TV-1 is authorized to operate on Channel 13ZR.
The installation of the proposed station will ensure that the second harmonic radiation
will meet the requirement for 80 dB attenuation below the fundamental carrier.
3.4
Reradiation of "Ghost" Reflections of Television Signals
Broadcasting Procedures and Rules, Part 4 - Section C-7
It is proposed to continue to co-locate at the existing CKUA-FM-5 tower near Peace
River, AB. The proposed CKKX-FM operation will continue to utilize the existing
CKYL-FM-1 and CKKX-FM broadband antenna. No changes are being made to the
existing broadband antenna. The CKUA-FM-5 tower has been in existence for many
years without “ghost” reflections of television transmissions. Therefore, “ghost”
reflections of television transmissions are not expected to be a problem.

Channel Selection and Interference Analysis: (Cont’d.)
3.5
Isolation of Transmissions
The proposed CKKX-FM station will be combined with the existing CKYL-FM-1
station using a custom made FM combiner.
Isolation of transmissions will be carefully considered in the use of the FM combiner
proposed. The use of a common transmitting antenna, with careful selection of the
proposed combining system, will result in minimum interaction between
transmissions.
The existing CKKX-FM antenna is in the same aperture as the CKUA-FM-5 antenna.
However the stations have operated this way for a number of years without any
problems.
3.6
Adjacent Channel Interference to Television Channel 6
The proposed channel of operation, Channel 291A (106.1 MHz), lies outside the
frequency range 88-92 MHz; therefore, consideration to television Channel 6 has not
been given in this submission.
3.7
Distortion of AM Patterns
Broadcasting Procedures and Rules, Part 3 - Section B-2.4.9(b)
There are no AM stations in the vicinity of the CKUA-FM-5 tower. Therefore,
consideration has been given but is not expected to be a problem.
3.8
Channels Separated by 600 kHz and 800 kHz
There are no FM assignments or allotments on either 105.5 MHz or 106.7 MHz
(channels separated by 600 kHz from 106.1 MHz) in the Peace River area.
Therefore, consideration to 3rd adjacent channel interference has not been given in
this submission.
There are no FM assignments or allotments on either 105.3 MHz or 106.9 MHz
(channels separated by 800 kHz from 106.1 MHz) in the Peace River area.
Therefore, consideration to 4th adjacent channel interference has not been given in
this submission.

Receiver Overloading and Intermodulation Interference
Broadcasting Procedures and Rules, Part 3 - Section C-5
3.9.1
There are a number of FM assignments and allotments in the Peace River area that
could contribute to potential intermodulation product (IM) interference. The
assignments, allotments and the proposed CKKX-FM channel considered in this
analysis are shown in Table 1.
Table 2 shows the list of all IM products in the Peace River area which could create a
potential for interference to the proposed station.
3.9.2
Table 3 shows the list of all IM products in the Peace River area which could create a
potential for interference to the proposed CKKX-FM station.
3.9.3
The proposed Channel 291A (106.1 MHz) and each FM channel allotted or assigned to
the Peace River area have been examined with respect to third order IM products of the
type 2f1-f2 and f1+f2-f3. It was found that Channel 291A (106.1 MHz) could generate IM
products that may appear in the Aeronautical NAV/COM Band (108-137 MHz).
3.9.4
The total population within the estimated 115, 70 and 54 dBu contours of the
proposed station is tabulated below. The population counts were taken from "Canada
Census - 2011" published by Statistics Canada.
Estimated Contours
115 dBu
70 dBu (3 mV/m)
54 dBu (0.5 mV/m)
Population Enclosed
419
8,297
14,734
The 54 dBu contour of the Peace River stations enclose the estimated 115 dBu
contour of the proposed station. Therefore, the population within the overlap area is
419 persons. The applicant is aware of its responsibility to remedy valid complaints
of receiver-generated intermodulation interference within the 115 dBu contour.
The estimated 115 dBu contour is shown in Figure 6.
The applicant is aware of the requirements to remedy valid complaints of immunitytype interference to radio-sensitive equipment within the appropriate EMCAB field
strengths.

Antenna System:
It is proposed to utilize the existing Bext TFC2K 8-bay circularly polarized nondirectional antenna. The antenna is side-mounted on an existing 152.4 m tower with
its radiating centre 135 m above ground level. The antenna radiates circularly
polarized waves with a non-directional radiation pattern.
The antenna gain is 4.4 relative to a half-wave dipole.
In Figure 3 the location of the first minima in the vertical radiation pattern is shown at
a depression angle of approximately 7°. This would cause a minima at a distance of
approximately 1.1 km from the proposed transmitter site. Since there are few listeners
at 1.1 km from the proposed site, no reception problems are anticipated due to the
radiation null.
The antenna is fed by a single run of 7/8" foam transmission line 149 metres long. At
106.1 MHz, the loss in the transmission system will be 1.862 dB which results in a
system efficiency of 56.2%.
