| - | ====== Omni VI / VI+ Varying Keyer Speed Fix ====== | ||
| - | **From the Ten-Tec Reflector May 31, 2001** | ||
| - | I'm a little perplexed by this - we've had reports from some (I'll have to define "some" also: a few, not all, not the majority) Omni-VI Plus owners that the keying speed with the internal keyer will be subject to a little bit of variation. There is an easy fix for this problem involving the addition of a .01 capacitor. Please give us a call at (865) 428-0364 and ask to speak with Don Prouty in our service department. We'll be happy to describe the fix and send you the part at no charge. | ||

| - | I called Don Prouty at Ten Tec today and here is the fix: | ||
| - | |||
| - | Put a .01 uf capacitor across the violet and brown leads of cable "D" on the logic board. Logic board is just under the top cover. | ||
| - | Cable "D" is the only cable on that board with colored wires going to it. Cable "D" has a violet, a white and a brown wire going to it. | ||
| - | |||
| - | Don suggests simply soldering the capacitor to the top of the connector, use minimum heat and be reasonably quick to avoid melting the connector or wire insulation. Alternatively, one could strip back a bit of insulation (this is usually more difficult in the center of a wire) and solder to the wires just above the connector. | ||
| - | |||
| - | Note: Voltage rating of the capacitor is unimportant as this is a 5 VDC line we are filtering. OK, OK it must be a 5 VDC rating or higher! | ||
| - | |||
| - | They will send you the part if needed, but every Ham who knows what end of a soldering iron is hot will have one in the junk box. | ||
