The transmissions originate from orbiting satellites at very low power, therefore, it takes a very large dish to receive these small signals for re-transmission. Over the past ten years, interference has become more prevalent at our satellite farm on Chatham Heights Road. Now it has reached the level where many of our receivers no longer are able to provide reliable service. For those of you interested in a more technical explanation, here is one source

The source article points out the "services in large areas covering intercontinental and global communications provide a wide range of services for distance learning, telemedicine, universal access, disaster recovery, national security, air navigation and safety, e-government. We have been able to determine the interference we are receiving is sporadic (not constant), and very strong. The spurious emission splatters across almost the entire C-band spectrum, rendering filters useless. We have not been able to determine the source of this interference, despite concerted efforts to do so. We have been able to determine the signature produced would indicate it is a ground-to-ground transmission and not listed in any databases confirming its use. I have talked with a number of experts in this field and the consensus is we are likely the victim of some government use, be it national security or the like. Regardless, there is no viable solution to our problem, at least not one that restores reliable C-band reception.

Fortunately, we have been able to restore most of our network programming services with an IP solution. In some instances, an IP solution doesn't exist, and in those cases we have had to provide alternate programming. thisTV Network provides no alternative to C-band at this time, and the interference has rendered this source no longer viable during daytime hours. For whatever reason, the interference only occurs during the daylight hours. Our C-band reception is unaffected during the overnight hours. 

Until a solution is found, our programming of thisTV Network will be limited to midnight to 6 AM. Should the interference become present during the overnight hours, we will be left with no recourse, but to discontinue thisTV Network.
