[TenTec] ten tec omni 6 plus

[Bob McGraw K4TAX]

Lee:

Well a Tentec 563 is indeed an Omni VI, and is not a Plus.  If the 
option 3 has been added, then it is an Omni VI opt3.  That makes it 
close to having the features to a Omni VI Plus and many will incorrectly 
indicate that it is an Omni VI Plus.  If it is a true Omni VI Plus then 
it is a model 564 and will have the Omni VI Plus on the front.

As to issues you describe.  Due to the age of the radio it is very 
common for the various connectors inside to oxidize and cause 
problems.   I suggest one clean each connector, male pins, with a 
contact cleaner applied to a Q-Tip.  Scrub the male pins and then 
exercise that connector 2 or 3 times, on and off with the female 
connector.  This provides adequate wiping action to clean the both parts 
of the connectors.  Do this one connector and cable at a time, being 
careful not to mis-plug a connector until all have been cleaned.    This 
usually correct most intermittent and other seemingly failed issues.   
This includes issues with the front panel and display board.    For 
this, remove the two screws on the top left and right side and the front 
panel will tilt forward for easy access.

Also the external RX antenna switch is noted to cause receive issues.  
Again, a good cleaning usually corrects the issue.  As a word of 
caution, do not spray contact cleaner into the radio. DeOxit is my 
favorite although others work as well to clean contacts.

These radios are really quite solid in performance.   Routine 
maintenance and cleaning keeps them working for another 30 years.
