I put my TIC to hardware, and have started testing it. Here is a sample run comparing it against the 5334B with an off frequency OCXO. I've scaled and rotated to tried to cancel out the length of the cables to the 5334B. Still early days with it, yet. http://www.evoria.net/AE6RV/TIC/TICvs5334B.png Bob - AE6RV
