V-Soft Communications Propagation & FCC Allocation Software Broadcast/RF



From preparing basic coverage maps, as seen in our galleries, to AM, FM, TV, STL, Microwave,  DTV and LPTV engineering work our Doug Vernier Telecommunications Consulting division (DVT) can help.

Doug Vernier, owner and principal engineer, is a seasoned broadcast engineering consultant. He has been in the business for well over 30 years and has a life-time certification from 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.  (View the bottom of this page for various presentations.)

Doug Vernier is our president and senior broadcast engineer/technical consultant. Kate English is one of our technical consultants who can help you in your work with the FCC. 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
  5. STL Frequency Coordination

FCC applications and engineering

  1. DTV upgrade projects and new station applications
  2. FM upgrade projects and new station applications
  3. AM upgrade Projects
  4. FM and TV Channel allocation petitions
  5. Due diligence for sales or purchases
  6. Station site moves studies and FCC applications
  7. First/second service analysis (307B) and mapping
  8. Calculation of population within FCC contour overlaps
  9. Demographic analysis of market service.
  10. License applications
  11. TV analog and digital translator, FM translator engineering and applications
  12. FM and TV booster stations
  13. S.T.L. path analysis, frequency searches and applications

Site Evaluations

  1. Examine signal coverage and penetration
  2. Coverage improvement projects
  3. FM and TV Field strength measurements

Stations watch and alert service

  1. Monthly mailed channel-studies of client’s stations to alert against interference or competitive filings
  2. Alerts by telephone

Auction support

  1. Auction support with regard to coverage and market analysis
  2. Post auction FCC filings
