Project Echo was another portable communications system produced by TMC, one for which I do not have the Military Designation.  If you know anything about this system, please let me know.

It appears that the system was composed of four trailers.  Two contained a pair of GPT-40K transmitters, along with antenna control systems.  The other two trailers comprise a pair of 75KW diesel generators (each) to power the transmitters.
