[BC] RCA phono plugs - How far back?

[DHultsman5 at aol.com]

For many years  KKB-364 Dallas Police Department  on 1714 kHz.  (or cps.) 
back then maintained the dispatcher only on the 1714 AM channel.  They used alot 
of their old 6 volt DC receivers for 1714 kHz. even into the early 1960's with 
a slant wire operating into the WRR-AM Auxiliary tower that was next to the 
WRR-FM tower at the South end of the Cotton Bowl.

>From the early 1930's  DPD had [police car transmitters around 30 mHz. AM and 
1714 receivers in the cars for two-way communications.   After they moved to 
45.66 mHz. FM in the early '50's the 1714 equipment was maintained and used 
for a non-selective one way paging system to officers assigned to warrant 
serving and other jobs not requiring 2-way communications.

The transmitter used was a Western Electric Model 303-C  1 kW. AM rig.
