Must See Software:
Probe 5™ – Professional level RF propagation modeling, DTV/TV, communications systems coverage and FM broadcast coverage and interference analysis. With this release, Probe 5 becomes a 64 bit program that can use all your computer’s memory instead of just 2 MB. Probe 5 produces spectacular “atlas” type maps – now with authentic U.S. topographic map backgrounds. The program integrates a high-resolution population database with V-Soft’s state-of the-art polygon mapping. For predicting coverage and interference, the program features these methods: Longley-Rice, Okamura-Hata, Cost-Hata, PTP #1 & #2, Line of sight, ITU, standard FCC and the new NSMA OHLOSS method. Probe 5 is bundled with with the current FCC broadcast station FM and DTV databases, V-Soft’s advanced polygon mapping, land cover and census databases.
FMCommander™ – Combines detailed service and interference FCC FM contour color mapping with commercial and LPFM minimum separation spacings and contour-to-contour frequency searching in one integrated package. Find new ways to upgrade your station or to move its transmitter site under short space. Integrates FCC data, census data, terrain data, tower, airport, AM stations, railroads, rivers, major highways, city boundaries, county boundaries and lakes and oceans into one complete FM channel search package. Our latest version of this program contains the proposed FM class C4 separations.
AM-Pro 2™ – Calculates and plots standard and grid-based AM coverage and interference based on the FCC AM rules. AM-Pro also performs AM ground-wave and automated sky-wave RSS allocation studies and it creates detailed allocation maps with polygon shaping. AM-Pro is is used daily by the FCC. The program contains a switch to implement the FCC’s proposed AM rejuvenation rules.
Microwave-Pro 2 is now using the industry standard NSMA methodology. This software program is our top-of-the-line microwave frequency allocations and path analysis program 
for the broadcast auxiliary services, Part 101, COALS and CARS projects. It produces the required “prior notification” (PCN) mailing lists to complete your studies. The new version adds bi-directional channel analysis and contains a new point search tool to identify microwave paths in the vicinity of wind farms or other large blocking structures.
