Update: On air issues 10/5/11

We are currently experiencing issues with our Station to Transmitter Link (STL). As I am troubleshooting this problem I am finding that our signal to noise ratio (SNR) is fluctuating. This leads me to believe that one of two things is happening, either the transmitter is drifting or we are getting interference. In both cases I’m going to have to spend the next several hours determining the problem.

I have already contacted the manufacturer of the microwave system and have a conference call with them first thing in the morning. If we are able to eliminate interference as the cause of the problem, they are putting together a new system to send overnight. I will update this blog regularly over the next few days as to where we are with this process.

In the meantime, I have lowered the power on the transmitter in hopes of increasing the SNR.

    have had no reception for over an hour now! Not just the broken signal now there is none and no IT update on this site. Come on how long is going to take to get this fixed? Issue has been going on for days now.
