My guess is the battery has died for the clock and other functions. A quick post in the Yahoo group for TS-940 confirms what is most likely a dead battery. There are 2 sets of batteries in the TS-940, one is for the sub display and the other is for ????  If I am going to open it up, I am going to replace both sets. A little research has found that I can replace them with a round lithium cell, like the ones computer BIOSes use.

Search for a better VHF/UHF Dual band Mobile Antenna

 

Since transferring within my company to a different office theTM-D710 in my car is getting much more use during my daily commute to and from work. For the most part I can get into the local repeater, but at the far end of my communte I am not holding the repeater as well as I should. I guess it is time to look for ways to improve, one way is a better antenna.
