[R-390] test equipment

[rbethman]

I actually find my AN/URM-25D to STILL be effective.

It warmed up for a few hours, had a high stability HP counter in-line, 
AND for three days it was rock solid.

The only thing I've had to do with it from a maintenance standpoint in 
the recent past, was to remove the power cord, trim it back, and 
re-attach it.  It developed a "quirk" that "IF" the cord was run to the 
left, I got no power.  "IF" the cord was run to the Right, power was had.

I follow the NAVSHIPS manual for it.  Perform the "zero" per manual, and 
calibrate.

Checks against WWV also.

When I have to, I'll replace it.  Don't have a NEED to as of yet.  It 
sure beats the OLD GR-1001A! <LOL>

The VTVM is a TS-505D/U.
