From preparing basic coverage maps, as seen in our galleries, to AM, FM, TV, DTV and LPTV engineering work our Telecommunications Consulting division can help.

Doug Vernier, owner and principal engineer, is a seasoned broadcast engineering consultant. He has been in the business for over 25 years and is certified by the Society of Broadcast Engineers as a "Professional Broadcast Engineer." Doug is regularly called on to deliver presentations within his expertise at broadcast engineering conferences throughout the U.S.

Among our staff are technical consultants Kate Michler and Adam Puls.  John Gray is our director of research and development. Our clients are numerous, from virtually every state in the country. Whether you require a new frequency or an upgrade for an existing station the consulting staff can help you.  Call us to discuss your broadcast engineering projects (800 743-3684.)

The following is a list of services we regularly provide:

Coverage maps 

1.) FCC standard FCC predicted signal contour levels AM, FM, TV, DTV, LPTV, LPFM and communication stations.

2.) Longley-Rice coverage maps using numerous more sophisticated routines for best "real world" predictions." (Other propagation prediction methods are available including Okamura/Cost Hatta and line-of-sight Shadow.)

Maps can be provided with underling topography, road/streets and political boundaries (large file), land cover or population scatter-gram. 

Ethnic origin, household and population demographics analyses

Interference maps

1.) Standard FCC contour overlap or U/D interference area representations

2.) FM radio Longley-Rice or TIREM defined coverage areas with interference areas subtracted; including population analysis.

3.) DTV incoming or outgoing interference analysis using FCC prescribed OET 69 methodology

4.) Client select interference analysis based on specific receiver specifications

Frequency searches

1.) FM spacings channel studies 

2.) FM contour to contour non-commercial educational, translator and Section 73.215 shortspace studies. 

3.) DTV, NTSC, LPTV, TV translator and Class A channel studies

4.) AM allocation frequency searches

FCC applications and engineering

1.) DTV upgrade projects and new station applications

2.) FM upgrade projects and new station applications
