[GreenKeys] NAVY modem

[WA5CAB at cs.com]

Group,

No, it is either CV-57/URA-6 or CV-71/URA-7.  With two Field Change 
modifications (the small toggle switch between the Narrow-Wide switch and the Tone 
Control and the hole labled LP CUR above and between the MOD BAL and % MARK 
control access holes) that don't happen to be covered by the manual that I have.  

Plus although the screws for the piano hinge were put back in, someone has 
removed the air intake cover that covered the air intake screens and part of the 
setup controls in the middle of the front panel.  And unfortunately on the 
CV-57, CV-60 and CV-71 that's where the nameplate is/was.
