[R-390] Classified Equipment

[Raymond Cote]

As far as dates go, The R-390A was being taken OFF my submarine in about 
1965 and being replaced by the R-1051.   I remember as the Radio men were 
complaining that the 390A was a better radio and easier to tune up and down. 
My contact with them was that I was asked to work on them as an Electronics 
Technician.   The purpose of this note is to relate that the R-390A was 
waiting for us at the pier as the sub returned to port and the 1051 
disappeared.  The radio gand and the Comm officer were not impressed with 
the 1051.  So if the 1051 was already set to replace the R-390A by mid 60's 
the 390A was out for some time before that period.
