Attached is my screen display similar to other on here. Both signals are of equal amplitude. At the suggestions of others I have carefully checked the Left and Right and Ground outputs from the Teensy Audio adapter for continuity to the "Exciter" output of the Main board. Everything checks out and there are no shorts betweem "L, "G" and "R". I am wondering if anyone else has found a reason for this issue other than the Teensy audio adapter signals for the QSE board. Any suggestions will be greatly appreciated! From what I can understand the QSD inputs are connected through a 20db attenuato to the QSE outputs for this test. My QSD have been moridifed to enable QSE and QSD simultaneously as documented in the latest calibration procedure. Thanks and 73, Frank K1FFJ <IMG_1795_1_.jpg> -- Jack, W8TEE
