[TenTec] Resolved: Omni 6+ Opt 3 problems

[N6QW]

Thanks to all who responded. The problem is fixed and here is why.

The manual I have is for the Omni VI and it is silent about once you get the 
Choose on the display you must push in 1 2 or 3 on the keypad to select the 
sub-menus. This was a change when the factory installed the Opt 3. When I 
bought the radio direct from TT there was an addendum document that explains 
you must select one of the sub-menus --in this case it is menu 1. [Somehow I 
missed reading the detail in that document.]

Once you select 1 then turning the tuning knob will pass you through the 
selections (or repeatedly pressing the enter key) until you get to the clock 
and first you must select whether the clock is on or off (up /down keys) and 
if you choose "on" simply enter the correct time via the keypad. Press lock 
twice and the radio will return to normal and the clock will work.

The keying function is also set in the menu 1 -- when I reset it --it went 
to "off" the default. The proper selection is LCO and with the up/down key 
you can select for K1 to operate by selecting LOC on.

Mike Bryce also had a great suggestion about the connectors -- the radio had 
not been used for several years and so that too should be done.

Thanks to all who replied -- the time is now correct and the relay works.

The good news is I didn't touch anything in the radio. I did learn how K1 
works and I did learn how to set things in the menu -- plus I had quite a 
few nice emails from some very helpful hams!
