| + | ====== Model 961 Speaker 60 Hz Hum Fix ====== | ||
| + | **From the Ten-Tec Reflector May 18, 2007** | ||
| + | I just attempted to use the built-in speaker on the 961 for the first time and am experiencing a 60 Hz hum which is quite audible. | ||
| + | |||
| + | I do not hear this hum when using the Omni VI's built in speaker, nor when using headphones. | ||
| + | |||
| + | It is loud enough that it is annoying. | ||
| + | |||
| + | Has anyone else experienced and fixed this? | ||
| + | |||
| + | Tnx\\ | ||

| + | Thanks to those who offered suggestions. | ||
| + | |||
| + | The winning suggestion came from Jack Burchfield, the president of Ten-Tec, who responded to my e-mail enquiry with "remove the ground wire which runs from one side of the 961's speaker to its chassis ground". | ||
| + | |||
| + | Works just fine now. No hum at all. | ||
