[TenTec] small white connectors

Thu Jul 7 09:53:55 EDT 2016

Al, you are correct, the white two pin plastic connectors are very small and have, what appears to be gold plated male pins and not anything I would want to physically manipulate because of their more fragile construction.
Question: Al are you very familiar with the evolution of the Omni VI to the Omni VI with factory installed option 3 ? I have had my Omni VI over 20 years and sent it back to Ten Tec for the option 3 upgrade. I have NEVER personally worked on it and always returned it to Ten Tec for repairs, upgrades and adjustments. I have NEVER studied the schematics of the Omni VI and that is the basis for my question to you.
I have been seeing discussions on the reflector regarding the TCXO in the Omni V!. Thence the following questions:
1. Did the early production (1992-1993) Omni VIs have a TCXO ?
2. Did the later models have a TCXO added ?
3. Did the option 3 factory upgrade change the type TCXO ?
4. Are the early Omni VIs less prone to serious TCXO problems ?

My Omni VI is working great except to the occassional disconnect  of the small connector. The frequency readout on 75 meters seems to be about 400 hertz low, so when I call the 3.925 net I set the readout to 3.924.6. Stability appears excellent. Transmitted audio is great according to K5QDA, my brother, who knows my voice better than anyone except K5MOL, Barbara, my wife.
If you can comment on the TCXO history of the Omni VI, please do. If you would like to involve another TEN TEC lover/historian, please feel free to do so. Thanks and 73, John, K5PGW

 Lee,

AMP Mate-N-Locks are used for the power connectors. The connector in question 
is for an internal low-level signal of some sort and is much smaller.
