K0P Special Event Station Belle Isle and Section Report Corrections


Michigan always seemed to be first in many things, here’s another first “the first broadcast to police cars”. (read the attached excerpt below).

We invite local Amateur Radio enthusiasts to come to Belle Isle on April 7th between 10 AM and 4 PM, and bring their low power (QRP?)  emergency communications gear and help us ‘work’ the Special Event station K0P and celebrate the 90th anniversary of the first Radio broadcasts to police patrol cars.

Come have fun, enjoy the day, the company and meet different folks.

This should be a good time to check out emergency communications gear with minimum preparation and quick and easy antenna setups.  (I think too many of us treat Field Day more as a contest than an check of our preparedness and a chance to improve our emergency operating skills.)

Contact Kimball Williams, N8FNC (k.williams@ieee.org) or Bill Boyke, N8OZV (wboyke@ford.com) for more details.




The Psychic Friends comment is even funnier if you spell it correctly




HamCon 2018 dates are October 6th and 7th 2018 (calendars are new and complex)




I copied the traffic counts incorrectly on the section report. I only received one complaint.

Milestones:One-Way Police Radio Communication, 1928


Detroit, MI Dedicated May 1987



At this site on April 7, 1928 the Detroit Police Department commenced regular one-way radio communication with its patrol cars. Developed by personnel of the department’s radio bureau, the system was the product of seven years of experimentation under the direction of police commissioner, William P. Rutledge. Their work proved

the practicality of land-mobile radio for police work and led to its adoption throughout the country.


The plaque can be viewed in the Harbormaster Station on Belle Island of Detroit, Michigan, U.S.A., at the front south-west corner near the main entrance door to the building.


In the 1920s gangster era, bank robbers and bootleggers made clean getaways time after time, to the great consternation of police. For this was before reliable mobile- radio communications existed, communications that could have quickly dispatched patrol cars to the scene of the crime.


But in 1928, a dedicated Detroit patrolman and an electronics buff devised the first successful one-way radio link between police headquarters and cruisers. Critical news of crimes in progress could now be transmitted from the stationhouse to police cars as they drove.


Electronics was a fledgling science when Detroit Patrolman Kenneth Cox and Robert L. Batts, an engineering student, built a stable radio receiver and antenna system. Their successful one-way radio, coming after years of trial and error, was installed in April 1928. The Detroit Police Department made history as the first to dispatch patrol cars regularly by radio. Many city police departments shortly followed suit with their own systems.


Between 1921 and 1927, radio buffs Kenneth R. Cox, Walter Vogler and Bernard Fitzgerald, all Detroit police officers, experimented with radio sets they had Installed in the back seat of a Model T Ford police patrol car.

The receivers picked up signals, but not very consistently. Frequently, broadcasts would fade out as the car passed large buildings or under railroad bridges. Also, police had no designated band on which to broadcast, so the system operated like any radio station. The station was appropriately called KOP and listed locally as an entertainment station.

To meet FRC (Federal Radio Commission, predecessor of the FCC) licensing requirements, police officers broadcast recorded music in between lists of stolen vehicles and descriptions of missing children.


Persistent work by Cox and Robert Batts led to the development of an improved receiver in 1927. A broadcasting station, W8FS, was set up on Belle Isle and regular dispatches began in 1928. (Source: Detroit Free Press).
