AM Revitalization Software

V-Soft Communications has added “AM revitalization” capability to its AM-Pro 2 software to study AM station allocations using the new FCC AM revitalization rules and proposals. Using a simple check box, studies can be run with the current rules or the newly proposed rules.

For daytime allocation studies, proposed D/U ratios and protected contour levels can be examined automatically, i.e. without user intervention. For example, for first adjacent relationships the proposed rules use a 1:1 ratio or a D/U ratio of zero dB, while the old rules used a 2:1 ratio or a six dB D/U. For nighttime allocation work, the new protection ratios (for first adjacent) and the 50% RSS exclusion method can be used and the “ratchet rule” power reductions are now gone. These changes allow users to easily compare and examine improvement possibilities under the “AM revitalization” proposed rules. For existing AM-Pro2 users on technical support, the update will be available, without charge, in the next automatic download.
