Happy 100th Birthday Denver Radio Club!

Happy 100 Years Happy 100 Years

The Mountain States Radio Association of Denver was the forerunner of the Denver Radio Club, Inc.
The first election of officers was held on January 19, 1917.

The first President was Donal L. Clark, 9ADH.
Colorado was then a part of District 9, and, at that time, there was no assigned prefix to the calls.

Our next Denver Radio Club Meeting will be on

Wednesday, January, 18th, at 7 pm.

Our meeting presentation topic is:

Game Day Frequency Coordination

Plaque Displayed at Events Which Require Frequency Coordination

Presented by Jim Schoedler

At sports stadiums, large concerts, and other public venues, there may be literally hundreds of devices transmitting and receiving RF in very close proximity to each other. Preventing, and/or troubleshooting, radio frequency interference is the primary job of the event frequency coordinator.

The NFL uses multiple frequency coordinators, known as Game Day Coordinators, at every football game. Whatever the title, the job starts well before the event with building a database of users and frequencies and finishes when the last use of RF at the event is completed. In between the job requires a variety of people and technical skills.

Jim Schoedler is the Society of Broadcast Engineers' radio frequency coordinator for Denver and the Front Range of Colorado. Jim is also a game day RF coordinator for the NFL Broncos and the Colorado Rockies Baseball Club. In 2008 he was the on-site frequency coordinator for the Democratic National Convention, held at the Pepsi Center. In 2014 and 2015 he was a frequency coordinator at the NFL Super Bowl.

In his talk Jim will discuss the range of frequencies used at a typical venue, the methods used for coordination, the tools used at the venue, and some of the pitfalls and successes he has experienced in his 10 years of performing frequency coordination.

Much more information, and Jim's Bio, is available in the January issue
of the DRC Roundtable Newsletter.

This will be a "Don't Miss" presentation...
please mark your calendars now to attend!


We will be meeting at the Jefferson County Administration & Courts Bldg.
100 Jefferson County Parkway, Golden CO
Hearing Room #2
Coordinates: 39.727962N , -105.201500W
