[TenTec] OMNI 5 GOES DEAD ON 40

[Carl Moreschi]

The battery backed up RAM in the Omni V does not use the battery.  It 
uses a RAM chip with a built in internal battery that cannot be changed. 
  These chips were made many years ago with 10 year life lithium 
batteries in them.  You can possibly buy a new one but even the new ones 
are more than 20 years old and their internal batteries might also be bad.

The 40 meter problem is most likely the 40 meter crystal.  When I had my 
Omni V I found that I could adjust the trimmer on the 40 meter crystal 
and make it run.  I ended up with about a 2 khz frequency error on 40 
meters but it worked.  My N4PY Omni V ship has a setup for recalibrating 
in software and this solved my 40 meter problem.  But your battery 
backed up RAM chip may not be as easily solved.
