Check the Industry Canada TAFL. plop in my coordinates 45.4154 north by 75.6720 west, and see for yourself. http://sd.ic.gc.ca/pls/engdoc_anon/w...raphical_input
It is bad. DDMMSS is 452455 by 754017
I actually used to build pre-amps with low pass filters for channel 50 and below only - using a very nice 54143 preamp design I came up with. That has been completely shelved. The interference Im getting is WITHOUT a pre-amp. Here is the text of my complaint:
To whom it may concern,
I am writing to submit a formal complaint of interference to my television reception of Ottawa UHF TV channel 60 ( at 746 MHz CFMT-tv "Omni 1" network) as well as UHF TV channel 43 (at 644 MHz, CHRO-tv "A Channel" network in Ottawa). I have a line of sight to both of these stations with normally a perfect picture on both with loads of fade margin. I live at 169 Lees Avenue on the top floor (13th) facing south. Both of these channels show a very distracting pattern of interference now. I do not have a pre-amplifier attached to my antenna, which is a simple dipole plugged into a coax plugged into the back of the TV set. I actually have 2 TV sets both of which are having these interference problems. One of the TV sets is a recent LG model which also has an HD tuner. I have also noticed some pixelation on HD over-the-air channels that was not there in the past. I have tried moving the antenna many places but it has not helped.
The same high-pitched whining sound that is coming from the TV from interference (Tv also has strong visual distortion) can also be heard on my landline non-wireless telephone and my computer speakers, as well as my electronic keyboard (again very distracting and is worst by the window where I spend most of the time in the apartment). I believe these to be rectified radio signals that are so strong that they overpower my basic electronic devices. They are non-stop 24/7 high pitch sounds. I have tried common mode choke coils and even shielding with tinfoil but nothing seems to work.
I live across the street from 180 Lees Avenue, where I have noticed 2 PCS/cellular base station antennas recently installed and pointed at a tilt angle directly toward my apartment. They are about 68 meters away when looking at a map on Google Earth. I looked at the Industry Canada TAFL and there are apparently 2x 955 watt ERP base stations pointed at 290 degrees azimuth toward my apartment from 68 meters away with what appears to be a tilt angle directed at my apartment (license number 1382963), a single 800 MHz base station of 600 watts ERP pointed directly at my apartment, and a 1200 watt ERP base station transmitting at 734 MHz (license number 5110000).
There are other base stations on the building across the street but they are pointed elsewhere. I have calculated the total ERP of these combined 4 stations at 3710 watts ERP, or times 2.2 = 8162 watts EIRP (effective Isotropic radiated power). I must admit it is unnerving to live in a place that is fully exposed to these emissions. The filed strength at 75 meters (add from 68 horizontal meters displacement) would be 100 mW/meter square, which is only about 17 dB less than safety code 6 (and closer if you count for internal reflections in my apartment).
Is there anything you can do to help me with this severe radio interference?
