Particularly true if the interference is from a broadband source such as an automobile ignition system, florescent light fixture, computer, motor, etc. Less likely if the interference is from a fixed frequency source such as a licensed transmitter.
The the fixed frequency source is quite likely to affect only one or two channels. FM broadcasts are a common source of single channel interference to OTA TV. Of course, it could be coincidence that the weakest TV signal happens to be the victim of a fixed frequency interferer.
In the cases of fixed frequency sources of interference, the likely frequencies to be interfered with will be odd multiples of the frequency transmitted. In your case, real CH-45 is 656 MHz to 662 MHz. So your first suspects would be operating on frequencies 1/3, 1/5 or 1/7 of the frequcie range of real CH-45.
