Looks like the SIGNAL LED is not lighted.

26 dBu (19 uV) is pretty miserable. You've got something horribly wrong unless this is a 20 mile hop, and even then the received signal levels should be at least an order of magnitude better.

Looks like it's less than a 20 inch hop! :lol:

I had to jump back to the picture in the previous post a couple times before I realized the picture above is a split-screen of both ends of the system. :)

I assume you had both dishes peaked for maximum signal.

26dBu is better than 10, but you should have better performance on a 10-mile hop. When the dish at the new studio was installed, is there a chance it was installed in the wrong polarity? Also make sure you're not peaked on a side lobe or reflection.

I must be missing something...the Nicom unit at the top of the picture appears to be an FM broadcast transmitter or exciter, not a 950 MHz STL transmitter.

A picture of the actual STL transmitter in operation might be instructive.

I was snickering initially at what appeared to be a RSL and TSL900 sitting in the same rack but after a closer look, it appears that the picture is of the RSL900 RX and a NT30 exciter.
