[Milsurplus] Dang Dang Battle Stations

[howard holden]

All,

The GQ (battle stations) and collision alarms are generated by a special 
oscillator in the 1MC general sound system. One section of the oscillator is 
keyed by a small slow - about 60 RPM - synchronous motor with a cam hitting 
a microswitch. The oscillator is keyed fast attack, slow decay, making the 
"bong bong". The collision alarm section is an oscillator whose frequency 
slowly rises in pitch when the switch is thrown, and when released and 
thrown again the pitch drops and starts to rise again. Both feed through the 
1MC amps, and are in the 1MC cabinet.

It's all done electronically (even in WW2).

We have a working one onboard the USS Ling (SS297, and sorry no spares.
