Signal Problems on 91.5
We now believe that the problem lies in the signal that is sent from the Cold Springs tower over to the Laughlin tower. The strength of that signal is not strong enough to overcome whatever is interfering with it. We do see that a lot of antennas have been recently hung right next to our STL antenna at Cold Springs and the could be interfering. And we are going to try to climb up to that antenna and inspect the cable going into it. It is weird that this problem mainly shows up around 4 PM in the afternoon. Something that interferes seems to get turned on right around then. But our own equipment should be able to withstand it. So it is a problem that has not been fixed yet. If we can't solve it with these simple fixes, then we are going to have to hire tower climbers who take signal analyzers up and put them in line to assess it. this is expensive and has to be done while the signal is turned off. We hope it doersn't come to this, but we have to do what it takes to solve it.
Big stations get around this sort of thing by having entire alternate STL sets with separate antennas operating on different licensed frequencies feeding into alternate STL units. the only way to guarantee uptime is to have full redundancy along the entire path of the radio signal chain. KZYX and KZYZ has never had that. We know that we need it and we are paying the price for it now. It was a big and long term mistake for this organization to not build this as it went along. We have to correct this and we will correct it. But it will take time and money. There is no other way.
