[Milsurplus] Dang Dang Battle Stations

[Marty Reynolds]

Howie - I worked u fm LST-325 on 20-cw during the CX.  Bofe 'a us on
SB-102s

One of but two prior-life electronics packages remaining are the 1MC and
a 24V DC supply to run "green radios."  (their 'customers' used green
radios).  That 60s 1MC uses 4 6550s

There were 4 Stromberg-Carlson 1MC sets aboard 'til a junk purge
expunged them.  Read overboard.  They used 838s & were prolly 300w ea.
Manual had survived & called it a "battle announcing system"

Dint see the 'battle stations' dang-dang/cam-job documented though.

LST-325 bunch funny.  The aboard-ship Heath presence in CX was source
of some derision - yet the 1MC gets deep sixed.

Tnx info!
