[R-390] Manual Correction

Greetings.. RE  Manual. NAVSHIPS 0967-063-2010... Radio Receiver R-390A/URR.

I don't use it often but recently had reason to look up parts list  and
check bandswitch alinement.

 Chapter 6 . para 6.2 .5 .4 has incorrect  information at point 4.

' Connect multimeter AN/PSM -4 between pin 6 of XV 205 and pin D of
J208----"

 

This should be pin 6 of  XV 207 and pin D of J208.

 

Checking the  schematic will show  'why is it so' . The Army manuals and Y2
K don't have the error.

 Not being aware makes a real chore out of unloading the RF module to find
no problems.
