Appendix 1 – Supplementary Brief
Technical Amendment – CFHK-FM St. Thomas
Overview of application
1.
This is an application by Corus Radio Company, a wholly owned subsidiary of Corus
Entertainment Inc. (Corus), to amend the licence of CFHK-FM St. Thomas, Ontario.
Corus proposes to change the authorized contours of CFHK-FM by: (i) relocating the
transmitter site; (ii) increasing the average effective radiated power (ERP) from 16,700
watts to 22,000 watts; and (iii) increasing the effective height of the antenna above
average terrain (EHAAT) from 150 metres to 179.6 metres.
2.
The purpose of this technical amendment is to overcome fourth adjacent channel
interference to CFHK-FM’s signal caused by CHST-FM London, which is operated by
Rogers Broadcasting Limited (RBL). CHST-FM transmits on the frequency 102.3 MHz
which is the fourth adjacent channel to CFHK-FM on 103.1 MHz.
3.
Corus proposes to relocate CFHK-FM’s transmitter to CHST-FM’s transmitter site,
consistent with Industry Canada guidelines for addressing such issues. Co-location with
CHST-FM will allow us to better equalize the signal strength of the two stations, thereby
eliminating fourth adjacent channel interference.
4.
This application is intended solely to correct CFHK-FM’s technical reception problems.
It will not impact any other station in the market.
Current reception issues
5.
CFHK-FM operates on 101.3 MHz with an average ERP of 16,700 watts. From its current
transmitter location approximately 10 miles north-east of St. Thomas, it serves the
communities of St. Thomas and London and the surrounding primarily rural areas.
Based on Statistics Canada 2011 census data, CFHK-FM’s 3 mV/m contour encompasses
a population of just over 450,000 persons.
6.
The RBL-owned station CHST-FM London broadcasts from a transmitter location in
London, at a site owned by Bell Media Inc., on 102.3 MHz. CHST-FM’s FM channel is
therefore fourth adjacent to that of CFHK-FM.
7.
In Broadcasting Decision CRTC 2012-490 the Commission approved an application by RBL
to increase the average ERP of CHST-FM from 5,840 watts to 20,400 watts, and the
maximum ERP from 12,100 watts to 100,000 watts.
8.
The purpose of the power increase was to improve CHST-FM’s reception within its
authorized contours; however, it also had the effect of significantly increasing the
strength of the CHST-FM signal relative to that of the Corus-owned station CFHK-FM.
9.
Because of the fourth adjacent channel frequency relationship, the result was to create
technical interference to the reception of CFHK-FM, particularly in the vicinity of
2
the CHST-FM transmitter site where the signal strength disparity between the two
stations is most pronounced. Corus became aware of this particular interference issue
shortly following the implementation of the power increase of CHST-FM to its
maximum ERP of 100 kW.
10.
Earlier this year Corus conducted an on-line survey in which listeners were invited to
respond to six questions concerning the technical quality of their reception of CFHK-FM.
The survey garnered responses from 604 listeners and, of this number, 190 (31.5%)
reported reception/interference problems, the majority of them clustered in areas close
to the CHST-FM transmitter site in London. This is the usual result of fourth adjacent
channel interference, which typically occurs close to the transmitter site of the
interfering station where its signal strength is significantly higher than that of the station
receiving the interference.
11.
Appendix D includes a map of the London/St. Thomas area with the locations of
listener reports of signal reception issues linked to Forward Sortation Area (FSA) postal
codes. This graphical representation clearly demonstrates the high incidence of
reception problems in the vicinity of the CHST-FM transmitter site in London, in the
N6A FSA postal code.
12.
London is an important part of CFHK-FM’s market area and as such, it is important that
we maintain a signal of as high a technical quality as possible in the area. The presence
of fourth adjacent interference from CHST-FM significantly limits our ability to properly
serve our listeners in the London area.
A relocation of the transmitter site to CHST-FM’s site is the optimum solution
13.
Corus retained engineering consultants D.E.M. Allen & Associates Ltd. (DEMA) to
investigate the fourth adjacent channel interference problems being experienced by
CFHK-FM and to recommend a solution to these problems. The DEMA report is also
included in Appendix D.
14.
As detailed in the report, DEMA estimated the signal levels of CFHK-FM and CHST-FM
at six specific locations where listeners had complained of fourth adjacent channel
interference. DEMA concluded that the differences in signals levels between the two
stations at those locations are sufficient to cause fourth adjacent channel interference on
many receivers.
15.
In such cases, Industry Canada’s rules strongly recommend that fourth adjacent channel
stations be co-located if possible to avoid such interference. DEMA agrees that this is the
appropriate solution to resolve the interference problem. At the proposed technical
parameters, DEMA states that “[c]o-siting CFHK-FM at the CHST-FM site will equalize
the field strengths of CHST-FM and CFHK-FM in the problem areas and will
substantially diminish, if not eliminate any instances of fourth adjacent interference.”
16.
The CHST-FM site is owned by Bell Media Inc. It is located just south of London,
approximately 15 km north-west of CFHK-FM’s existing site. Corus has secured an
3
agreement with Bell Media Inc. to lease space on their tower to mount the new antenna
for CFHK-FM. A copy of this agreement has been provided as Appendix C to this
application.
17.
The location of available space on the Bell Media Inc. tower has determined the new
EHAAT of 179.6 m, a slight increase from the 150 m EHAAT at CFHK-FM’s existing
location. DEMA has selected an antenna design and ERP that will roughly equalize
signal strengths between CHST-FM and CFHK-FM, maintain an excellent signal in St.
Thomas, and closely duplicate the population covered by the proposed 3 mV/m contour
as compared to the existing 3 mV/m contour.
18.
Based on Statistics Canada 2011 census data, CFHK-FM’s proposed 3 mV/m contour
will encompasses a population of 455,096 persons, an increase of less than 1% from the
number of persons covered by the existing 3 mV/m contour.
19.
With regard to the impact on CFHK-FM’s signal quality in St. Thomas, the DEMA report
notes that the new transmitter site maintains a clear path into St. Thomas. The proposed
3 mV/m contour continues to fully enclose St. Thomas, meeting the requirements of
Industry Canada respecting the provision of satisfactory service to principal target
centres. In addition, DEMA calculated field strengths at several locations in St. Thomas
using Predict software, and confirmed that the estimated field strengths at those
locations would be well above the desired 3 mV/m for a principal target centre.
20.
Co-siting with CHST-FM is the optimum technical solution and is consistent with the
strong recommendations of Industry Canada respecting the solution to instances of
fourth adjacent channel interference. Moreover, space is available on the tower used by
CHST-FM and Corus has been successful in securing an agreement with the owner of
the tower to lease space for CFHK-FM’s antenna.
21.
In these circumstances, Corus has not pursued alternate solutions in addressing the
current reception difficulties. Given the specific technical issue to be addressed, Corus
submits that there is no other technical solution that can effectively address fourth
adjacent channel interference problems.
The proposed amendment will have no impact on other stations in the market
22.
As noted above, CFHK-FM serves the communities of St. Thomas and London. The
other English-language commercial radio broadcasters serving these markets are as
follows:
•
•
•
•
23.
Astral Media Radio G.P. – CJBK, CKSL-FM, CJBX-FM and CIQM-FM London
Blackburn Radio Inc. – CKLO-FM London
My Broadcasting Corporation – CKZM-FM St. Thomas
Rogers Broadcasting Limited – CHST-FM London
The proposed technical amendment is based solely in the need to correct fourth adjacent
channel interference problems. Other than a relocation of the transmitter site
4
approximately 15 km to the north-west, CFHK-FM’s proposed technical parameters are
very comparable to its current parameters and the total population enclosed within the 3
mV/m contour will change by less than 1%. CFHK-FM will continue to serve the
communities of St. Thomas and London, the only difference being an elimination of the
interference currently experienced by many of our listeners in London.
24.
In these circumstances, Corus submits that there will be no change to the competitive
landscape in St. Thomas and London, and therefore no impact on the other Englishlanguage commercial broadcasters in the market.
Respondents to this application
25.
It is our position that approval of this amendment application will not have any impact
on other stations in the St. Thomas/London market and will not affect the competitive
balance. As such, we submit that there are no parties that are adverse in interest to the
applicant.
26.
Nevertheless, to ensure complete transparency with respect to this application, Corus is
treating My Broadcasting Corporation, Rogers Broadcasting Limited, Blackburn Radio
Inc. and Astral Media Radio G.P as respondents to this application. These parties are
being served with copies of this application pursuant to the CRTC Rules of Practice and
Procedure.
27.
In addition, as discussed in the Engineering Brief, the following licensees operate FM
stations that are short-spaced to the proposed CFHK-FM transmitter site:
•
•
•
•
•
28.
Astral Media Radio G.P. – CKLH-FM
Canadian Broadcasting Corporation – CBEF-1-FM Leamington
MZ Media Inc. – CFMX-FM Cobourg
Points Eagle Radio Inc. – CKCI-FM Sarnia
Rogers Broadcasting Limited – CHST-FM
If not already included on the list of respondents who operate commercial Englishlanguage radio stations in St. Thomas/London, Corus will also treat these parties as
respondents to this application.
Conclusion
29.
Corus submits that the proposal to change the authorized contours of CFHK-FM St.
Thomas is fully justified based on technical reception issues due to fourth adjacent
channel interference, as documented in this application.
30.
The proposed solution is consistent with Industry Canada recommendations for
resolving fourth adjacent channel interference problems. The proposed technical
parameters have been carefully chosen to resolve current interference problems while
ensuring no impact on other broadcasters operating in the St. Thomas/London market.

Corus Radio Company, owner and operator of CFHK-FM, proposes to change the
parameters of CFHK-FM, St. Thomas, Ontario on Channel 276B (103.1 MHz) by
moving the transmitter location to the existing CTV tower near London, Ontario. A new
side-mounted custom panel antenna will be installed on the tower. The proposed facility
will operate with an ERP of 60 kW (H&V) maximum and 22 kW (H&V) average with
an EHAAT of 179.6 m.

Interference Analysis
3.2.1
Additional Interference Analysis
(Cont’d.)
Additional comments are provided below for select assignments and allotments.
3.2.1.1 CBEF-1-FM Channel 276A Windsor ON
CBEF-1-FM has Limitation #9, “Limited to 1 kW and 85.5 metres”. In view of the
fact that CBEF-1-FM is authorized for 1 kW at 77.5 metres, CBEF-1-FM is
essentially limited to existing parameters, or at best slightly above existing
parameters. No CBEF-FM-1 future interfering contour is shown on Figure 7.
3.2.1.2 CFMX-FM Channel 276C1 Cobourg ON
CFMX-FM has limitation #68, “Limited to 86.7 kW and 252 metres” that limits
CFMX-FM to existing parameters (see Figure 8).
3.2.1.3 CFMO-FM Channel 275C1 Collingwood ON
CFMO-FM’s Channel 275C1 operation is listed as AU in the IC database, and has
Limitation 99, “Future limitations” (see Figure 11).
3.2.1.4 CKCI-FM Channel 277A Sarnia ON
CFHK-FM has no limitations towards CKCI-FM. Therefore the allowable interfering
contour shown for CFHK-FM in the CBEF-1-FM interference analysis on Figure 13
is based on maximum CFHK-FM parameters. However, in view of CFHK-FM’s
limitations to other stations including Lapeer, MI, it is very unlikely that CFHK-FM
will ever be able to operate at max parameters.
The proposed CFHK-FM 48 dBu interfering contour will overlap the existing 54 dBu
contour of CKCI-FM resulting in an area of possible interference to CKCI-FM.
3.2.1.5 WCRF-FM Channel 277B Cleveland OH
WCRF-FM is operating at or nearly at maximum parameters for its class and
therefore no WCRF-FM future interfering contour is shown on Figure 14.

Channel and Interference Analysis: (Cont’d.)
3.3
Harmonic Interference
Broadcasting Procedures and Rules, Part 3 - Section C-6.1
The second harmonic of 103.1 MHz (Channel 276C1) is 206.2 MHz. This falls in
television channel 12. The nearest channel 12 allotment is ON-PT-1761, Chatham, ON
which is 87.1 km at Azimuth 230.6° from the proposed site. ON-PT-1761 is assigned
Channel 12R.
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 co-locate with the existing CTV tower near London, Ontario. The
proposed CFHK-FM antenna will be side mounted below the existing TV antenna.
The CTV tower has been in existence for many years without “ghost” reflection of
television transmissions, and all the transmitting antennas on the tower are mounted
co-linearly. Therefore, “ghost” reflections of television transmissions are not
expected to be a problem.
3.5
Isolation of Transmissions
The new CFHK-FM antenna is side-mounted on the existing 298.8 m tower with its
radiataing centre 161.5 m above ground level.
The following broadcast stations are co-located at the proposed site:
 CFPL-FM, Channel 240C1 (95.9 MHz)
 CHST-FM, Channel 272C1 (102.3 MHz)
 CFPL-TV, Channel 10R
Isolation of transmissions between the proposed station and other broadcast facilities
at the proposed site are not anticipated to be a problem due to the difference in
frequency, the co-linear mounting of the antennas, and the installation of filters and/or
combiners at the output of each transmitter.

3.6
Adjacent Channel Interference to Television Channel 6
The proposed channel of operation, Channel 276C1 (103.1 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 proposed tower; therefore, distortion
of AM patterns will not be a problem.
3.8
Channels Separated by 600 kHz and 800 kHz
There are no FM assignments or allotments on either 102.5 MHz or 103.7 MHz
(channels separated by 600 kHz from 103.1 MHz) in the St. Thomas and London
area. Therefore, no problem with respect to 3rd adjacent channel interference is
anticipated.
Channel 272C1 (102.3 MHz) is assigned to CHST-FM, London, ON (4th adjacent
from 103.1 MHz). It is the intent of the applicant to co-site with CHST-FM. One of
the reasons for co-siting is that CFHK-FM has had complaints of 4th adjacent channel
interference from CHST-FM in the London area and co-siting will minimize
interference to CFHK-FM. The proposed CFHK-FM ERP will not exceed the ERP of
CHST-FM by more than 20 dB in any direction. This will minimize the possibility of
4th adjacent channel interference to CHST-FM, and as per Section C-1.6.1 will
preclude CHST-FM from having any 4th adjacent channel interference remedying
responsibilities to CHST-FM (see Figure 15).
Channel 280C1 (103.9 MHz) is assigned to CKDK-FM, Woodstock, ON (4th adjacent
channel from 103.1 MHz). The proposed CFHK-FM 100 dBu contour intercepts the
area between CKDK-FM’s 70 dBu and 54 dBu contours (population 142,499). As
such, there is an area of possible 4th adjacent channel interference from the proposed
CFHK-FM to CKDK-FM (see Figure 16). CKDK-FM is also owned and operated by
Corus Radio Company.

Receiver Overloading and Intermodulation Interference
Broadcasting Procedures and Rules, Part 3 - Section C-5
There are a number of FM assignments and allotments in the St. Thomas/London area
that could contribute to potential intermodulation product (IM) interference. The
assignments, allotments and the proposed CFHK-FM channel considered in this
analysis are shown in Table 1.

The total population within the estimated 115 dBu contour is 19,208.
The applicant is aware of its responsibility to remedy valid complaints of receivergenerated intermodulation interference within the 115 dBu contour (see Figure 17).
The applicant is aware of the requirements to remedy valid complaints of immunity
type interference to radio-sensitive equipment with the appropriate EMCAB field
strengths.
The proposed channel and each FM channel allotted or assigned in the area have been
examined with respect to third order IM products of the type 2f1-f2 and f1+f2-f3. It
was found that the proposed channel could generate IM products that may appear in
the Aeronautical NAV/COM Band (108-137 MHz).

Exposure to Radiofrequency Energy
Broadcasting Procedures and Rules, Part 1 - Section 8.0
The proposed CFHK-FM Channel 276C1 (103.1 MHz) operation has been examined
with respect to "exposure to radiofrequency energy". It was found that the proposed
calculated power density at a distance of 2 m above ground level is below the
maximum exposure level for uncontrolled environments recommended in Safety
Code 6.
Given that the calculated levels at 2 metres above ground are well under 50% of the
uncontrolled environment exposure limit, no measurements are required.
Figure 6 shows the detailed profile of the estimated “exposure to radiofrequency
energy” levels.

Antenna System:
It is proposed to utilize a new Sira FMC-05/13 (4 x 3+1) 4-bay (3 panels per bay)
circularly polarized antenna. The antenna will be side-mounted on the existing
298.8 m tower with its radiating centre 161.5 m above ground level. The antenna
radiates circularly polarized waves with a directional radiation pattern.
The maximum gain of the antenna is 5.05 relative to a half-wave dipole. The average
gain of the antenna is 1.89 relative to a half-wave dipole. The horizontal radiation
pattern is shown in Figure 3. The vertical radiation pattern is shown in Figure 4.
In Figure 4, the location of the first minima in the vertical radiation pattern is shown
at a depression angle of approximately 17°. This would cause a minima at a distance
of approximately 528 m from the proposed transmitter site. Because of the height of
the site relative to the City of London, 0.5° beamtilt and 10% null fill is proposed to
eliminate possible reception problems.
The antenna will be fed by a single run of 3" air transmission line 390 m long. At
103.1 MHz, the loss in the transmission system will be 1.929 dB which is an
efficiency of 64.1%.

The geographical co-ordinates of the antenna are:
Latitude 42° 56' 59" North
Longitude 81° 15' 52" West
The overall height of the antenna system is:
298.8 m above ground level
577.3 m above mean sea level
Average elevation of terrain:
Elevation of radiating centre:
161.5 m above ground level
179.6 m above average elevation of terrain
This information is shown in Figure 5.

Average EHAAT = 179.6 m
The effective radiated power from which the distances to the various contours were
determined, was calculated as follows:
ERP = Transmitter Power x System Efficiency x Antenna Gain
Since the antenna radiating characteristics are directional, the antenna gain is a
function of the radiation in any direction relative to the radiation in the maximum
direction. The ratio is the relative field.
The antenna gain is obtained as follows:
Antenna Gain = (Relative Field)2 x 5.05
Example: Radial #1
Azimuth 0°
Antenna Gain = 0.9582 x 5.05 = 4.63471
ERP = 18.5 x 0.641 x 4.63471 = 54.961 = 55 kW to two significant figures
Data for determining the average elevation for all radials was obtained from the CRC
500 m Terrain Database.

CFHK-FM, ST. THOMAS ON
1.0 Introduction and Executive Summary
D.E.M. Allen & Associates Ltd. (DEMA) has been retained by Corus Radio Company to
investigate the fourth adjacent channel interference problems being experienced by
CFHK-FM and to recommend a solution to these problems.
CFHK-FM operates on 103.1 MHZ (Channel 276B) at a maximum ERP of 50 kW and an
EHAAT of 150 metres. CFHK-FM is licensed to and operated by Corus radio Company.
Specifically, Corus has received complaints of fourth adjacent channel interference
from CHST-FM to CFHK-FM in the London area.
To overcome the interference issue, it is recommended that Corus move CFHK-FM from
its present site to a site in the London area. The existing Bell Media site is the best
option for Corus.
2.0
Proposed CFHK-FM Change of Facilities
Corus Radio Company, the licensee of FM broadcasting station CFHK-FM 103.1 MHz
St. Thomas, Ontario is applying to Industry Canada and the CRTC to change the
facilities of CFHK-FM by moving the transmitter site from the existing CFHK-FM tower to
a tower owned by Bell Media. The maximum ERP of CFHK-FM is being increased from
the present 50 kW maximum ERP to a 60 kW maximum ERP. The EHAAT is increasing
from 150 metres to 179.6 metres.
A new custom panel type antenna optimized for CFHK-FM’s protection and coverage
requirements will be added to the Bell tower.
The purpose of this change of facilities is to eliminate the existing fourth adjacent
channel interference in London.
This report identifies the causes of the interference issues and how the move will
resolve the problem and still maintain coverage in the St Thomas area.

Interference Complaints
3.1
CFHK-FM Receives Fourth Adjacent Channel Interference from CHST-FM
CFHK-FM receives complaints of fourth adjacent channel interference from CHST-FM.
The complaints mostly come from listeners in the London area. CHST-FM transmits on
the frequency 102.3 MHz which is fourth adjacent channel to CFHK-FM on 103.1 MHz.
3.2
CFHK-FM and CHST-FM Site Locations
CHST-FM is authorized for and has recently implemented a power increase to a
maximum ERP of 100 kW. CHST-FM transmits from the Bell Media site located within
London whereas the CFHK-FM site is located approximately 17.5 kilometers south of the
centre of London.

3.2
CFHK-FM and CHST-FM Site Locations (Cont’d.)
Fourth adjacent channel interference usually occurs when the signal strength of one
station is considerably higher than the other station. The following map shows the
locations of the transmitting site of CFHK-FM and CHST-FM (at the Bell Media site).
It can be seen that the transmitter site of CHST-FM is located within London whereas
CFHK-FM is located south of London, outside of the City. This results in CHST having
significantly greater field strengths in London than CFHK-FM. Moving CFHK-FM to the
Bell site will equalize the field strengths of CFHK-FM with CHST-FM.

Interference Complaints (Cont’d.)
3.3
Industry Canada Recommends Co-Siting for Fourth Adjacent Channel FM
Stations
With respect to fourth adjacent channel stations, Industry Canada’s Broadcasting
Procedures and Rules Part 3 states;
“FM stations separated by 600 or 800 kHz and operating in the same
area may interfere with each other if not co-sited and therefore cositing is strongly recommended if possible.”
Industry Canada’s rules recognize and recommend that fourth adjacent channel stations
should be co-sited when possible. The proposed Change of Facilities for CFHK-FM will
co-site CFHK-FM and CHST-FM.
3.4
CHST-FM Field Strength Significantly Exceeds CFHK-FM in London
A comparison was made between the CFHK-FM and CHST-FM field strength levels at a
number of locations in London where complaints have been received or where Corus
staff has reported interference. The existing CFHK-FM and authorized CHST-FM field
strength levels were estimated using the program Predict version 2.08 developed by the
Communication Research Centre in Ottawa. The program Predict is a terrain-sensitive
software widely used by Industry Canada for estimating contours and field strengths.
Many measurement campaigns carried out by DEMA have shown that Predict is accurate
in estimating the field strengths of FM stations.

CHST-FM Field Strength Significantly Exceeds CFHK-FM in London (Cont’d.)
The following map shows a number of locations where listeners have complained of
fourth adjacent channel interference, or CFHK staff have experienced interference:
The following table compares the estimated field strength of the existing CFHK-FM
operation to the estimated field strength of CHST-FM. These levels were estimated at
9 metres above ground to correspond with the standard height used for broadcast
contours.

3.4
CHST-FM Field Strength Significantly Exceeds CFHK-FM in London (Cont’d.)
These estimated signals do not consider losses from buildings and trees, and the actual
levels could be lower. Due to the greater distance of CFHK-FM from London, the CFHKFM levels would be more affected by tress and buildings than the CHST-FM levels.
However, given that fourth adjacent interference occurs when one station has
significantly higher field strength than the other, these estimates are valid for
demonstrating the significant difference in field strength between CFHK and CHST.

The differences in signal level between CFHK-FM and CHST-FM listed above are
sufficient to cause fourth adjacent interference on many receivers.
Co-siting CFHK-FM at the Bell Media with CHST-FM site would substantially improve the
CFHK-FM field strengths at the above locations as shown in the following table:

Co-siting CFHK-FM at the CHST-FM site will equalize the field strengths of CHST-FM and
CFHK-FM in the problem areas and will substantially diminish, if not eliminate any
instances of fourth adjacent interference.

3.5
Existing CFHK-FM Site is Shadowed into London
Portions of London, particularly the downtown and inner core are located in the valley
created by the Thames River. As such, the low elevation of these areas results in
shadowing of the FM signal in these low areas. This is demonstrated below.
The following profile of terrain shows the path from the antenna at the existing CFHKFM site to a listener with a radio at 2 metres above ground in downtown London (in the
vicinity of One London Place Building).

3.5
Existing CFHK-FM Site is Shadowed into London (Cont’d.)
From the above, the signal path from the existing CFHK-FM antenna to the listener in
downtown is grazing due to the terrain, and in some places will be completely blocked
or shadowed by the terrain.
The effect of this will be that the CFHK-FM field intensity in downtown London will be
reduced by the attenuation caused by the terrain blockage.
The profile of terrain from the Bell Media site to the same point in the downtown area
is shown in the following:
The above two plots demonstrate that in order for CFHK-FM to have the same signal
path or “shot” into the downtown area of London as CHST-FM, that CFHK-FM must cosite at the Bell Media site.
The CHST-FM antenna is slightly lower on the Bell tower than the proposed CFHK-FM
antenna but this difference in height is relatively small when considering the path
clearances.

The Proposed Change of CFHK-FM Doesn’t Compromise the Signal
in St. Thomas
4.1
Bell Site Has a Clear Signal Path into St. Thomas
The profile of terrain was also evaluated from the Bell Tower to the center of
St. Thomas to ensure that the St. Thomas signal path isn’t compromised by the move to
the Bell site. The attached plot shows that the proposed CFHK-FM antenna at the Bell
site has a very clear signal path into St. Thomas. Therefore, the move of the CFHK-FM
site significantly improves the signal path into London and maintains a clear signal path
into St. Thomas.

The Proposed Operation at the Bell Site Maintains 3 mV/M Enclosure of
St. Thomas
The contours for the proposed CFHK-FM operation as filed with Industry Canada and the
CRTC are shown in Appendix A of this report. These contours have been calculated
using the method of curves required by Industry Canada.
Industry Canada’s Broadcasting Procedures and Rules Part 3 states;
A minimum field strength of 3 mV/m is required for satisfactory service to principal
target centres, where a target centre is any populated area defined as city, town,
locality, etc. as per Natural Resources Canada maps.``
The proposed operation meets this requirement by enclosing St. Thomas with the 3
mV/m contour.

4.3
The Proposed Operation at the Bell Site Provides Reliable Signal Levels in
St. Thomas
As an additional check to ensure that the field strength levels in St. Thomas are at
levels suitable for a community such as St Thomas, the realistic contours were
calculated and the field strengths at spot locations in St Thomas were also calculated.
Appendix B shows the realistic 3 mV/m contour determined using Predict 2.08v2. From
this map it can be seen that the realistic 3 mV/m contour encloses all of St Thomas.
The field strength at a number of spot points in St Thomas was calculated using Predict
2.08v2 to ensure that there are no localized anomalies in the field strength. The field
strengths were calculated at 9 metres above ground to correspond with IC’s
methodology. Field strength calculations were made at the locations shown below:

Recommendations
It is recommended that CFHK-FM move to the existing Bell Media tower. Moving CFHKFM to the existing Bell site using the proposed parameters in the Technical Brief will;
•
Equalize the field strengths in London between CFHK-FM and fourth adjacent
CHST-FM. This will eliminate or substantially reduce the fourth adjacent channel
interference that CFHK-FM presently receives from CHST-FM.
•
Meet Industry Canada’s recommendation that fourth adjacent channel stations
be co-sited.
•
Replace and improve the existing CFHK-FM shadowed signal path into the
downtown of London with a signal path from the Bell Tower that is not
obstructed by terrain.
•
Serve St Thomas with a signal path that is also not obstructed by terrain.
•
Maintain reliable service to St Thomas by enclosing St Thomas with a 3 mV/m
contour as required by Industry Canada for the principal community. The 3
mV/m contour calculated using both the method of curves and Predict 2.08v2
substantially encloses both St Thomas and London.
