V-Soft Adds Features to FMCommander 

The company has released a summary of all the program updates this year as an aid to users.

Standards of FM Allocation and Interference 

The simple view of interference meaning overlapping signal contours tends to overstate the area of potential interference. Jeremy Ruck explains.

Alternate Propagation Models 

While the FCC designed its pattern modeling method to be reasonably accurate over a fairly broad slice of circumstances in the United States, it tends to fall apart in situations in which terrain is abnormally smooth or cases where a particular propagation path has some fairly significant undulations.

RF Software RF Investigator v3 

Field strength program

V-Soft Adds Database Auto Updater 

The update allows program users to transparently update FCC and Industry Canada databases.

V-Soft Communications Probe 4 

Terrain analysis software

V-Soft Updates FM Commander to Version 6.3.0.48  

Updated U.S. Census Tiger graphics data is the highlight of the update.

V-Soft Adds FCC Activity Alerts to Service 

Using the e-mail addresses included in the applications, the service alerts users of construction permits granted, dismissals and other similar FCC activities.

V-Soft Releases New FCC 30 Sec. Terrain 

The database is the actual NGDC database used by the FCC.

V-Soft Offers Internet Security Option 

V-Soft has developed a system that allows a user to gain authentication through an online Web server in addition to the physical local or network key.

V-Soft Updates Zip-Signal Utility 

The database used by the program contains station and zip codes for the entire United States and was updated June 1, 2008

Taming a wild monitor point 

When monitor points suddenly exhibit surprisingly high field strength, one's first inclination is to look at the previous logs and ask the technical staff about the monitoring point's history

V-Soft Communications to Host its 6th Annual Broadcast Engineering Training Seminar in Las Vegas 

V-Soft Communications will hold its 6th annual engineering training seminar on April 12 and 13, at the Excalibur Hotel and Casino.

Engineering assistance 

Today's broadcast engineer has a much easier row to hoe than his counterpart in the middle to latter part of the 20th century.

Don Mussell reviews the RF mapping software.

Field Report: V-Soft AM-Pro 

Although there are many software options for evaluating FM stations, there are few software packages to evaluate AM stations. AM-Pro is perhaps the newest package available, and it is proving to be one of the best.

Field Report: V-Soft Probe II 

The Technical Research Department at Salem Communications reviews the RF mapping software.

Computerized planning and station engineering 

In the early days of radio engineering, it was necessary to calculate every value used in determining coverage and antenna design manually. Slide rules were the norm, and many engineers carried one in a hip holster -- well, almost. My slide-rule case certainly had a belt slot in it.

Field Report: RadioSoft Comstudy 2.2 

ComStudy 2.2 is a suite of RF study tools, the primary functions of which are the prediction coverage and interference, along with the study of AM and FM allocations. The software also supports TV and land mobile; however, my version does not support those functions. If I had to describe this software in just a few words, I'd have to say, feature packed.
