| + | The day after impedance matching all the Mid and High transducers had a circle around the outside of the Smith Chart. | ||

| + | |||
| + | Update 5/26/2015: Now every transducer on this device is displaying the open circle. I believe that all the transducers on this device are broken. It appears that a signal greater than 25 Dbm causes one of the busses to overload and burn up. | ||
