FMC NavRad/LRC....B757 and 777

I looked through the forum and haven't seen anything related to my question. Not that it's a huge deal,but why is it that I cannot insert an NDB freq. on the right side of the FMC? I can insert it on the left side. However, if I try the same freq. for the right side, the freq. just disappears.Also, why is long range cruise not active in the VNAV section of the FMC? Econ. seems to be the default. Was LRC not programmed in the making of this FMC? Just curious...Joe

Limitation of FS. Only allows one ADF. Some other developers used custom radio coding to get around this problem (PMDG, LDS).PSS rely on alot of default FS coding, hence no ADF2.
