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!

Pete,
the first line of troubleshooting this project would be to pop the top and
bottom, watch out for that speaker wire, and then one at a time pull and
reset each and every one of the MTA (mass termination assemblies) ---those
white connectors with the wire wires---
do that on each one and several times.
there can be oxide that builds up on the pin and by exercising the
connections, you'll fix a lot of problems.
I'm not saying that will smash your bugs, but it's a good place to start.
do every connection going to the logic board and the front panel.

Before I take out the Golden Screwdriver and really mess things
up --thought I would test the list to look for divine guidance.
I have a Omni 6+ Opt 3 that has been inactive for several years. I put
it back on line yesterday and for the most part it works FB.
I noted that the "clock time" was off by about 35 minutes. So in looking
in the manual I see that by holding in the "Lock" button for one second
gives access to the menus and the clock set is in Menu 1. Sure enough I
did that and the panel display read "Change". The next step is to hit
the "Enter" button to scroll through the 13 menus. Only in my case it
does not go through the menus but returns to the normal display as before
engaging the "Lock' button.
So then I thought perhaps a partial reset would cure the issue --nothing.
So next I tried the "master" rest process -- nothing --same issue. Then I
thought Ahhh -- the lithium coin cell battery needs replacing. I popped
in a NIB battery and still the same issue.
Perhaps related is another issue. Before I did the two resets --the NO
relay contacts on K1 worked so I could turn on a linear amp. That no
longer works. The cable to the amp was tested as was the amp switching
and they are good. ( The amp is a SB-200 with the soft key mod so I do
not think anything was fed back into the Omni 6 to kill the keying). The
keying relay K1 is triggered by Q16 (MPS6514) but the driving signal to
Q16 comes from the Logic Board via connector 59. U22, pin 4 sets the
driving signal to Q16. When this pin goes high it keys Q16 which engages
K1. So this may be the connection related to the first problem (after the
two resets) as the driving signal comes from the Logic board and it is
the same board which has a problem in not being able to scroll through
the menus.
Any thoughts or inputs are welcome. I would normally call TT but it
happened on Saturday and this is Sunday so I can't do that until
tomorrow.
Thanks in advance,
Pete N6QW
