TCS Intermodulation Software
Updated and Improved  04-12-01

For Windows® 32bit operating systems.


TCS Consultants, Inc., provides intermodulation calculation software for the analysis and calculation of intermodulation products generated by multiple transmitters on the same radio structure. This software is used to calculate interference from co-located transmitters that generate harmonics that may be in the same frequency as a receiver on the same site. This software will calculate virtually any range of frequencies (00,000.00001 MHz to 99,999.99999 MHz) and is FREE courtesy of TCS Consultants, Inc.
